    METHOD TO PRODUCE A
    IMAGE IN AN AREA OF
    IMAGE IN ONE
    PHYSICAL MEANS, AND MEANS CUSTOMIZABLE BY SELECTIVE EXPOSURE TO
    PHOTONS
    FIELD [0001] The present invention relates generally to the secure personalization of documents, and more particularly to personalization by producing an image on a document selectively revealing colored, black and white pixels exposing one or more layers of photon-sensitive materials to photons.
    FUNDAMENTALS [0002] Many forms of physical media exhibit customization of both mass production and end user. For example, identity cards may need to be produced for very large population groups, yet each individual card has to uniquely identify the person holding the card. The high volume manufacturing phase can be performed on relatively expensive equipment because the cost of the equipment can be amortized over very large production runs. On the other hand, end-user customization can preferably be carried out at customer sites in relatively low volumes, thereby requiring much lower equipment costs.
    [0003] For many identity cards, the security of all information in the wallet, whether digitally recorded or physical characteristics of the card, is of paramount importance. Security is sometimes linked to certain characteristics that reveal whether the environment has been physically violated. One mechanism to prevent attempts to breach identity cards is lamination. For ensuring the physical means in
    Petition 870190002500, from 01/09/2019, p. 4/95
    2/38 a lamination layer that cannot be laminated without destroying the physical primitive capacity of the medium goes far beyond protecting the safety integrity of the medium.
    [0004] A very important mechanism for limiting an identity object is the placement of a person's photograph on the identity object. Driver's licenses, passports, identity cards, employee badges, etc., all normally contain the image of the individual to whom the object is attached.
    [0005] Laser engraving provides a prior art technique for personalizing a post-shipment identity card with a photograph. Figure 1 is a detailed perspective view of the various layers that make up such a state-of-the-art ID card 50. The ID card 50 may include a layer of laser-engravable transparent polycarbonate 57. Selectively exposing an image area on the card with a laser, specific locations in the polycarbonate layer 57 can be turned black, thereby producing a gray scale image.
    [0006] Traditionally, polycarbonate (PC) ID products have been customized using laser engraving technology. This is based on a laser beam heating carbon particles within specific polycarbonate layers to the point where the polycarbonate around the particle becomes black. Although the particles could be chosen to be something other than carbon, it is the intrinsic property of polycarbonate that creates the desired contrast and number of levels of gray to produce, for example, a photograph. The gray tone is controlled by laser energy and scanning speed through the document. This technology

    is standard at the market ID. Meantime, an limitation of that technique is what images colorful cannot to be produced that mode. [0007] In certain markets and applications it is desirable Tue
    identity cards with color images.
    [0008] Traditionally, color photographs have been placed on identity cards using Dye diffusion thermal transfer technology (D2T2), which is available for PET and PVC products. Recently, the development of D2T2 technology has made it possible to customize polycarbonate cards in color as well. This technology requires a smooth printed surface and the printed image must be protected with an overlay film, which can also be of the holographic type. Gemalto S / A from Meudon, France has developed a desktop D2T2 solution that has been available on the market since the fall of 2007.
    [0009] One drawback to superficially printed color customization is that it is not as secure as photos
    recorded The laser and data that They are situated inside the structure in layer in polycarbonate, like illustrated at figure 1. [00010] In another alternative to technique previous, an Image
    color can be produced using digital printing before the product is checked. This allows for high quality images placed in ID wallets. This technology also has many disadvantages: the personalization and manufacture of the card body must take place on the same premises, which additionally has to be, typically, in the country of issue of the document because government authorities do not like to send civil registration data

    4/38 across borders, color printed photographs prevent the PC layers from merging into each other, and if any of the portfolios on a sheet are stained in additional production steps, the personalized portfolio must be reproduced from the beginning of the process leading to a process highly complicated manufacturing process.
    [00011] US patent 7,368,217 to Lutz et al., Multilayer Image, Particularly a multicolor image, May 6, 2008 describes a technique in which color pigments are printed on checked sheets and each color can be targeted up to one desired tone using a color sensitive laser.
    [00012] From above, it will be evident what there is a need to one method perfect for to provide one mechanism to put images in portfolios in identity and similar using one
    mechanism that produces tamper-proof color images, secure during a customization phase using inexpensive equipment, on the customer's premises.

    to the attached drawings that show, as an illustration, specific modalities in which the invention can be put into practice. These modalities are described in sufficient detail to allow those skilled in the art to practice the invention. It should be understood that the various embodiments of the invention, while different, are not necessarily mutually exclusive. For example, a specific feature, structure, or aspect described here with respect to one modality can be implemented in other modalities without departing from the spirit and scope of the invention. In addition, it should be understood that the location or arrangement of elements

    7/38 individual in each revealed modality can be modified without departing from the spirit and scope of the invention. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, appropriately interpreted, together with the full range of equivalents to which the claims are entitled. In the drawings, similar numerals refer to the same or similar functionality in all the various views.
    [00029] One embodiment of the invention provides a mechanism by which physical means such as ID cards, bank cards, smart cards, passports, valuables, etc., can be customized in a post-manufacturing environment. This technology can be used to place images on such articles within a lamination layer after the lamination layer has been applied. In an alternative embodiment, a protective lamination layer is added to the identity card after personalization. In this way, items, for example, smart cards, can be manufactured in a mass production mode in a factory setting and customized on relatively cheap and simple equipment at a customer location. The technology provides a mechanism to thereby personalize items, such as smart cards, bank cards, identity cards, with an image that is resistant to tampering. Here, for the purpose of providing a clear narrative, the term identity card is used to refer to the entire class of physical media to which the techniques described here can be applied even if some such physical media are not "cards" in a strict sense. . Without limiting the application of the term identity card
    Petition 870190002500, from 01/09/2019, p. 10/95
    8/38 is intended to include all of these alternatives including, but not limited to, smart cards (contact and contactless smart cards), driver's licenses, passports, government-issued ID cards, bank cards, ID cards employees, security documents, personal valuables, such as records, proof of ownership, etc.
    [00030] In a typical smart card life cycle, a card is initially manufactured in a factory setting. The manufacturing step includes placing an integrated circuit module and connectors on a plastic substrate, typically in the shape of a credit card. The integrated circuit module can include systems, programs and certain standard applications. The card can also be printed with some graphics, for example, the customer's logo.
    [00031] The card is then delivered to the customer.
    [00032] The customer, for example, a government agency, a commercial company, or a financial institution, which wishes to send secure identification cards to its customers, the end users of the cards, then personalizes the cards. Personalization, perso in the industry phraseology, includes the placing by the customer of its application programs on the card, and specific end user information on the card. Perso can also include personalizing the physical appearance of the card for each end user, for example, by printing a name or photograph on the card.
    [00033] After the wallet has been personalized, the wallet is shipped to the end user, for example, an employee or a customer of the customer, step 40.
    [00034] Other identity cards have life cycles

    Similar 9/38.
    [00035] Figure 1 is a detailed perspective view of a prior art identity card, 50, which allows some level of customization of the physical appearance of the post-shipment card, for example, by the customer. Such card 50 can, for example, have the following layers:
    . a layer of transparent polycarbonate (PC) 59. a layer of transparent laser-engravable PC 57. an opaque white PC core 55. a layer of transparent laser-engravable PC 53. a transparent PC layer 51 [00036] As anti-counterfeiting measures, the upper PC layer 59 may include some embossing 67 and a multi-laser image / changeable laser image (CLI / MLI) 69. To further increase security the card 50 may include features such as DOVID 65, that is, a diffraction optical variable image device such as a hologram, cinegram or other secure image, and a Sealy 63 window (a
    aspect in safety, provided by Gemalto S. A., Meudon, France, at the which one clear window that becomes opaque after violation is provided In the card). The 50 card can contain
    also an antenna system and non-contact chip 61.
    [00037] During customization, the laser-engrave transparent layers 57 and 53 can be provided with a gray scale image and identification text.
    [00038] Figure 2 is a top view of an identity card 100 according to an embodiment of the technology described here. In summary, the identity card 100 is provided with an image area 205 that is constructed of several layers of material located between a substrate (for example,
    Petition 870190002500, from 01/09/2019, p. 12/95
    10/38 example, a PC core) and a lamination layer. The bottom layer of these image area layers is a print pixel grid (see figures 3 to 8) that consists of a plurality of specifically arranged areas having different colors. The print pixel grid is covered by a transparent layer and an opaque layer of photon sensitive materials. The transparent layer can be selectively changed to a certain level of opaque black and the opaque layer can be selectively changed to transparent. In this way, by selective manipulation of the photon sensitive layers, any given location in the 205 image area can be made to display a specific color of the print pixel grid, black (or a darkened shade of the underlying grid sub-pixel) , or white. By selectively manipulating the photon sensitive layers of the addressable locations (as discussed below, the addressable locations are referred to here as sub-pixels) of the image area, an image can be produced. The structure of the print pixel grid and the photon-sensitive layers, and the process of manipulating these layers to produce an image are discussed in more detail below.
    [00039] Identity card 100 may have been printed with a company logo or other graphic. Through an exclusive process and manufacturing described in more detail below, identity card 100 contains a 203 color image, for example, a photograph of the intended end user, printed in an image area 205. Identity card 100 may have been additionally personalized with a printed name 207. The printed name 207 can be applied to the wallet using the same techniques as described here to apply an image 203 to the identity card 100.
    Petition 870190002500, from 01/09/2019, p. 13/95
    11/38 [00040] Figure 3 (a) is a cross section of the identity card 100 of figure 2 taken along line a-a. identity card 100 consists of a substrate 107. Substrate 107 can be constructed of a plastic material, for example, selected from polyvinyl chloride polycarbonate (PVC), acrylonitrile butadiene styrene (ABS), PVC in combination with ABS, terephthalate polyethylene (PET), PETG and polycarbonate (PC). As with the prior art identity card 50 of Figure 1, identity card 100 may include additional layers, for example, laser-engravable PC layers 53 and 59 and transparent PC layers 51 and 59.
    [00041] A print pixel grid 111 is located on a surface of substrate 107 (substrate 107 means here any of the inner layers of card 100, for example, similar to the opaque PC layer 55, transparent PC layer 53 or 57, or inner layers constructed of alternative materials) in an area of the substrate corresponding to the image area 205. The print pixel grid 111, which is described in greater detail below in combination with, for example, Figures 4 through 8, it can be printed on the substrate using conventional offset printing or using any other technique to precisely arrange a colored pattern on the substrate.
    [00042] The print pixel grid 111 is covered by a transparent photon-sensitive layer 105. The transparent photo-sensitive layer 105 is made of a material that converts from being transparent to a certain level of opacity after being exposed to photons in length specific wave and intensity. Suitable materials include polycarbonate
    Petition 870190002500, from 01/09/2019, p. 14/95
    12/38 carbon doped. Traditionally, polycarbonate (PC) ID products have been customized using laser engraving technology. This customization is based on a laser beam heating carbon particles within specific polycarbonate layers to the point where the polycarbonate around the particle becomes black. Although the particles could be materials other than carbon, it is the intrinsic property of polycarbonate that creates the desired contrast and number of gray levels to allow the creation of a photographic image. The gray tone is controlled by the laser force and scan speed across the image area 205. In this way, a layer of transparent carbon-doped PC can be selectively changed to an opaque layer along the darkness scale exposing the selected location with a laser. NdYAG or fiber laser. An Nd_YAG laser emits light at a wavelength of 1064 nanometers in the infrared light spectrum. Other available Nd-YAG laser wavelengths include 940, 1120, 1320 and 1440 nanometers. These wavelengths are all suitable for making a transparent opaque black or partially opaque PC layer with an intensity in the range of 10 to 50 watts. In a typical application, the Nd-YAG laser is scanned (in the manner discussed in more detail below) over the image area for a duration of approximately 4 seconds, exposing specific locations as needed. Fiber lasers that are suitable for making the transparent PC layer opaque or partially opaque operate at wavelengths in the range of 600 to 2100 nanometers. Although some lasers and specific wavelengths are discussed above, any alternative photon source, for example, a UV laser, which converts a
    Petition 870190002500, from 01/09/2019, p. 15/95
    13/38 spot on a transparent opaque PC layer can be used instead.
    [00043] The transparent photon-sensitive layer 105 is covered with an opaque layer 103 which can be changed to a transparent layer by exposure to photons at a specific intensity and wavelength. Suitable materials for the opaque to transparent photon sensitive layer include a white targetable ink that can be arranged on top of the transparent to opaque layer 105 through thermal transfer or matrix sublimation, for example. Examples include SICURA CARD 110 N WA (71-010159-3 1180) (ANCIEN CODE 033250) by Siegwerk Druckfarben AG, Sieburg, Germany, Dye diffusion thermal transfer (D2T2 inks available from the Datacard Group of Minnetonka, Minnesota, USA or Dai Nippon Printing Co., Tokyo, Japan. Such materials can be selectively altered by exposing specific locations by a UV laser at a wavelength, for example, 355 nanometers or 532 nanometers with an intensity in the range of 10 to 50 watts to a few milliseconds per addressable location (sub-sub-pixel) To change the sub-sub-pixels in the layer from opaque to transparent 103 the laser is continuously scanned over the image area exposing those sub-sub-pixels that must be changed from opaque white to transparent in the opaque-to-transparent layer 103 by evaporation or ink bleaching. In an alternative embodiment, the same UV laser wavelength that removes the ink from the opaque-to-tran layer sparente 103 can also be used to change the carbon-doped transparent-to-opaque layer 105 below the sub-sub-pixels removed from the transparent-opaque layer 103 when residual energy is available from the
    Petition 870190002500, from 01/09/2019, p. 16/95
    14/38 UV laser.
    [00044] In an alternative embodiment the opaque to transparent layer 103 is a photon-sensitive layer that is sensitive to a dry photographic process that does not require chemical image treatment. An example is a spirochirane photochrom with titanium oxide (similar to the material used to produce with PVC). This process is based on the photochemical behavior of colored complexes between spiropyranes and metal ions. THE
    figure 4 illustrates the reaction chemistry. When spiropyran SP2 401, which is structure closed, is exposed to light UV, transforms in a structure open 403 what it's colorful. An
    Suitable alternative for SP2 401 is indolinic spiropyran (3 ', 3'-dimethyl-1-isopropyl-8-methoxy-6-nitrospiro [2H-1benzopyran-2,2-indoline]).
    [00045] In an alternative embodiment, illustrated in figure 3 (b), the opaque to transparent layer 103 is augmented with a doped organic semiconductor layer 106. The doped organic semiconductor layer 106 is useful as an amplifier to improve the speed at which the opaque to transparent layer 103 changes from opaque to transparent. Example materials for the doped organic semiconductor layer 106 include polyvinyl carbazole and polythiophenes. A layer of polyvinyl carbazole 106 can be disposed by evaporating 2.5 grams of polyvinyl carbazole in 50 cubic centimeters of dichloromethane. The semiconductor layer 106 is preferably doped to match the energy levels required for a photochromic effect in the opaque to transparent layer 103.
    [00046] The photochromic effect of opaque to transparent layer based on spiropyran 103 can be obtained by
    Petition 870190002500, from 01/09/2019, p. 17/95
    15/38 exposure to ultraviolet or visible light. The preferred intensity is in the range of 50 to 200 watts at a distance of 30 to 300 millimeters for a duration of 10 to 300 seconds.
    [00047] The principle of preparing emulsions for a dry color printing process was patented by Prof. Robillard (US patent application 2004259975). The results of feasibility investigations are described in J. Robillard et al., Optical Materials, 2003, vol. 24, p. 491-495. The process involves photographic emulsions that exclusively require UV light or visible stripe to produce and fix images. Emulsions include color photochromic dyes and an amplification system and exhibit photosensitivity comparable to those of conventional known silver-containing materials. In general, this process is applicable to any type of media (paper, tissues, polymeric films).
    [00048] Finally, the identity card 100 is covered with an upper lamination layer 109a and a lower lamination layer 109b. lamination layers 109 provide security in protecting the image 203 produced in the image area 205 from physical manipulation. The upper handling layer 109a should be transparent to the photon wavelengths used to change the transparent to opaque layer 105 and the opaque to transparent layer 103. In addition, the lamination temperature should be low enough so as not to alter the transparent to opaque layer 105 or opaque to transparent layer 103, for example, in the range of 125 to 180 degrees Celsius. Suitable materials include PVC, PVC-ABS, PET, PETG, and PC.
    [00049] Figure 3 (c) is a cross-sectional view still
    Petition 870190002500, from 01/09/2019, p. 18/95
    16/38 of another alternative modality for a 100 ”identity card that can be personalized with a color image produced on the wallet during the customization phase. A 111 ”photon sensitive print pixel grid is located above a carbon 105 doped PC layer, which in turn is located above a 107” white opaque PC layer. The 111 ”print pixel large in this case consists of multiple sub-sub-pixels that can be selectively removed by exposure to photons of appropriate wavelength and intensity. The 205 image area can be customized with a 203 color image by selectively removing colored sub-sub-pixels from the 111 ”photon sensitive pixel grid and by subjecting the carbon 105 doped PC layer selectively to the photon energy that alters selected portions from transparent to black.
    [00050] While it is desirable to prepare the entire portfolio during the manufacturing phase of the portfolio life cycle, in some embodiments the application of the technology described here which is not practical because the top laminating layer 109a could prevent evaporation of dyes from the opaque layer for transparent 103 or 111 ”. Therefore, if changing one of the photon-sensitive layers requires evaporation or some other form of material removal in the process of transforming from one state to another, for example, from opaque to transparent, the top lamination layer 109a can be added during the customization phase, for example, after the image area 205 has been customized as described here. Such lamination can be performed using DNP CL-500D lamination media from Dai Nippon Printing Co., Tokyo, Japan or other appropriate lamination technology.
    Petition 870190002500, from 01/09/2019, p. 19/95
    17/38 [00051] Turning now to the structure of the print pixel grid 111, for which a small portion is illustrated in figure 5. The print pixel grid 111 is composed of a set of print pixel 501. One print pixel 501 corresponds to a pixel in an image's bitmap, for example, a pixel in a .bmp file. In the small portion of a print pixel grid 111 illustrated in figure 5, it contains a grid of 4 x 7 pixels of print 501. In a real-life print pixel grid, 111, a grid having many more print pixels in each dimension it would be necessary to produce a meaningful image. Each print pixel 501 contains 3 rectangular sub-pixels 503a, 503b and 503c, each corresponding to a unique color, for example, green, blue and red as illustrated in the example. For the purpose of being able to produce various color combinations, each 503 sub-pixel is subdivided into a plurality of 505 sub-pixels. In the example in Figure 5, each 503 sub-pixel is composed of a 2 x 6 grid of sub -sub-pixels 505.
    [00052] The term print pixel is used here to the equivalent of a pixel in a digital image that is printed on the print pixel grid and having a plurality of subpixels that individually form a portion of the print pixel, and the areas corresponding to the photon-sensitive layers that cover the 205 image area. A sub-pixel is a single color area of the print pixel. A sub-sub-pixel is a single addressable location in a sub-pixel. In this way, a sub-pixel is composed of one or more sub-sub-pixels. A sub-subpixel can have its color exposed from the print pixel grid or any of the photon-sensitive layers.
    [00053] Figure 6 is an illustration of a pixel grid of
    Petition 870190002500, from 01/09/2019, p. 20/95
    18/38 alternative print 111 'composed of print pixels 501' which are composed of hexagonal sub-pixels 503 '. As illustrated in figure 6 (b), each hexagonal sub-pixel 503 'is composed of six triangular sub-pixels 505' which when connected form the hexagonal sub-pixel 503 '. As it should be recognized, although figures 5 and 6 illustrate two different print pixel structures, there are many more structures possible. All of these alternatives should be considered equivalent to the print pixel structures illustrated here as examples.
    [00054] Figure 7 is a 701 color photograph of a model and is presented here as an illustrative example. Consider the lower left quarter 703 of the model's right eye (right and left being from the viewer's perspective). This portion 703 of the model eye is shown in greater magnification in figure 8. Image 701 is created by selectively rotating specific colors from the transparent to opaque layer 105, the opaque to transparent layer 103, and the print pixel grid 111 for each sub-sub-pixel 505 that make up the print pixels 501 forming the image. Consider the lower left impression pixel 501 ”of the eye portion 703. The lower left impression pixel 501” is located on the lower eyelid of the model and is pinkish red. To obtain this coloring, a large portion of the red sub-pixel 503c ”is revealed by 8 of 12 red sub-pixels 505 of the underlying print pixel grid. The blue sub-sub-pixels are completely obscured by the opaque white layer and most of the green sub-pixels are obscured by the black layer, thereby providing a neutral brightness and mainly coloring

    red for the pixel of print 501 ”. [00055] A figure 9 (a) illustrates the manipulation gives layer in opaque to transparent 103 and the transparent layer for opaque 105 to produce colors desired for one pixel in
    print 501 for displaying the cross section of each of a black print pixel 501a, a white print pixel 5091b, a red print pixel 501c, and a blue print pixel 501d. for each print pixel 501a through 501d shown in figure 9, each column represents a subpixel 503. Sub-pixels 505 are not shown in figure 9. To produce a solid black print pixel 501a, the opaque to transparent layer 103 is made transparent (T) by exposing the print pixel 502 to the change of state light necessary to change the opaque to transparent layer 103 of the print pixel from opaque white (W) to transparent (T). To produce a solid white print pixel 501b the print pixel 501b is not illuminated because the default state for the opaque to transparent layer 103 is white. For a solid white print pixel 501b, the transparent to opaque layer 105 can have any value since it is absorbed by the opaque white layer 103. However, it would typically be made transparent (T). To produce a red print pixel 501c, both the opaque to transparent layer 103 and the transparent to opaque layer 105 are configured in their transparent state (T) for the area over the red sub-pixel (R). This effect is produced by exposing the opaque to transparent layer 103 to photos of changing state to opaque to transparent layer 103 while leaving the transparent to opaque layer 105 in its native state. The opaque to transparent layer 103 for the

    20/38 green or blue sub-pixel can be changed to transparent (T) and the corresponding location on the transparent layer to opaque 105 can be changed to black (K) to reveal a black sub-pixel. By combining black and white sub-pixels or sub-sub-pixels for non-colored sub-pixels or sub-sub-pixels, they can be used to adjust the brightness of pixel 501. The blue pixel 501d is produced similarly to the red pixel 501c.
    [00056] Figure 9 (b) illustrates the manipulation of the 111 ”photon-sensitive print pixel layer and the carbon-doped transparent layer of the 100” alternative identity card illustrated in Figure 3 (c). to create a black pixel 501a "the removable ink from all 503 sub-pixels of the 111" photon sensitive print pixel layer location is removed (-). As with the opaque to clear white layer 103, certain inks can be targeted with UV laser exposure and thereby removed. The same ink can be transparent to a YAG laser that can be used to transform the transparent to opaque layer 105 into all black (K), thereby making the 501a ”pixel black. To make pixel 501b ”white, the pigmentation for the print pixel layer 111” is removed (-). However, the transparent to opaque layer 105 is not exposed to a laser and therefore remains transparent (T), leaving pixel 501b ”white. For red, the pigmentation of the green and blue sub-pixels is removed (-) through exposure to a UV laser while the transparent to opaque layer 105 corresponding to the red (R) sub-pixel, respectively, can be transformed into a shade of gray to provide a darker background. It should be noted that figure 9 (b) only shows some combinations
    Petition 870190002500, from 01/09/2019, p. 23/95
    21/38 possible. By changing the adjacent sub-pixels between black and white, as well as the gray scale value of the underlying layer, many different effects can be achieved.
    [00057] Although figure 9 illustrates the manipulation of photon-sensitive layers at a sub-pixel level, it should be noted that effective print pixels 501 are composed of very sub-sub pixels 505 and that many variations in brightness and color can be produced by selectively revealing colored, black and white sub-sub-pixels in a suitable combination to produce the desired color and brightness for a given 501 print pixel.
    [00058] Turning now to computing masks for the transparent to opaque layer 105 and the opaque to transparent layer 103. The determination of which sub-pixels 505 should be left opaque white, should be turned to opaque black or should reveal the underlying color of the print pixel grid 111 is controlled by a mask for each of the photon sensitive layers. These masks can, for example, have an on / off value for each sub-sub-pixel in the 205 image area or a value indicating the level of opacity that the specific photon-sensitive layer must provide for each sub-sub-pixel. Figure 10 is a flow chart that illustrates the steps of a modality for computing these masks. The description should not be considered limiting since there are other possible algorithms for producing the masks.
    [00059] Process 110 accepts a digital image 121 as input, for example, in .bmp format. An image file in .bmp 121 format is a bitmap for each pixel in an image for specific RGB (red-green-blue) values. Process 110 converts image file 121 into a mask
    Petition 870190002500, from 01/09/2019, p. 24/95
    22/38 white exposure 125a than a black exposure mask 125b. These exposure masks 125 are provided as input to a controller 355 (figures 12 and 13) to control the exposure of sub-sub-pixels of the transparent-to-opaque layer 105 and opaque to transparent layer 103. The purpose of designing the masks 125 is to produce an image that resembles the image in the digital image file 121.
    [00060] It is assumed here that there is a one-to-one correspondence between each pixel of the source image 121 for each printing pixel 501 of the printing pixel grid 111. Otherwise, a pre-processing conversion algorithm can be applied . In addition, process 110 is described with respect to square printing pixels 501 with three rectangular sub-pixels 503 for green, blue and red, respectively, as shown in figure 5. In alternative modalities, other pixel and sub-pixel formats and colors are possible. For example, in an alternative, the print pixel pattern includes black or white sub-pixels (or both) that can take the place of one of the photon-sensitive layers 103 or 105. In yet another alternative, the pixel pattern of printing includes colors such as cyan, magenta and yellow to allow greater variability in colors displayed. For such alternatives, process 110 would be modified to account for such different structures in the print pixel pattern and the photon sensitive layers of coverage.
    [00061] From a perspective an objective of process 110 is to determine how much of each colored sub-pixel 503 should be visible for each printing pixel in the resulting image 203. A second objective is to determine the opacity for the transparent-to layer -oppaque 105 because this layer
    Petition 870190002500, from 01/09/2019, p. 25/95
    23/38 assume varying degrees of opacity. Third, process 110 determines the ratio between sub-sub-pixels of fully obscuring, black and white and the locations for such sub-sub-pixels.
    [00062] The brightness of each source pixel is determined, step 127, by the following formula:
    public static float brightness (float red, float green, float blue) return (0.30 * red + 0.55 * green + 0.15 * blue);
    } [00063] Where red, green and blue are numerical components of the source image and have values in the zero and Max range (255). The resulting brightness value is therefore in the same range (0 Max (255)).
    [00064] Next RGB values adjusted in whitelevel are computed, step 129. This calculation starts with the computation of whitelevel:
    whitelevel = minÇredigreei ^ blue) [00065] Adjusted RGB values are computed by:
    Petition 870190002500, from 01/09/2019, p. 26/95
    24/38
    AdjustedRED ~ red - whitelevel AdjustedGREEN = green - whitelevel AdjustedBLUE = bine - whitelevel [00066] Where red, green and blue are the RGB values in the source image.
    [00067] Next, a hue intensification is computed and the adjusted RGV values are additionally adjusted for the hue intensification, step 131, as follows:
    maxComponent = max (AdjustedRED, AdjustedGREEN, AdjustedBLUE) if {maxComponent o 0) then, j-,. í (255 - (255 —maxComponent) / 2) „„ | hueFactor = min —--- 2 --------------- t — L, 30 maxComponent J
    AdjustedRED = hueFactor * AdjustedRED
    AdjustedGREEN = hueFactor * AdjustedGREEN
    AdjustedBLUE = hueFactor * AdjustedBLUE [00068] This calculation produces for each 501 print pixel the portion size of each red, green and blue sub-pixel to be fully revealed. The portion size is converted to conform to the number of available sub-sub-pixels for each color sub-pixel:
    nuniSubSubRED = totalSubSub * AdjustedRED 4- 255 mtmSubSubGREEN - totalSubSub * AdjustedGREEN 4-255 mimSubSubBLUE - totalSubSub * AdjustedBLUE 4-255 [00069] Where totalSubSub is the number of sub-sub-pixels 505 per
    Petition 870190002500, from 01/09/2019, p. 27/95
    25/38 sub-pixel 503 and numSubSubRED, numSubSubGREEN, and numSubSubBLUE each are floating point values corresponding to the number of sub-sub-pixels that would be needed to cover sub-pixel 503 with the corresponding portion of red, green and blue, respectively.
    [00070] Next, each print pixel is adjusted in brightness, step 133, as follows:
    totalRevealed = sum (numSubSubRED, numSubSubGREEN, numSubSubBLUE) numSubSubTotalCover - (totalSubSub * 3) - totalRevealed r , / numSubSubTotalCover * (255 - brightness) numSubSubTotalBlackCover = round ----------------- ------------------ (255 [00071] Where brightness is the brightness computed in step 127.
    [00072] Step 133 thus computes the general portion of each 501 print pixel that must be completely opaque black to be used in computations described below.
    [00073] The number of sub-sub-pixels revealed for each color and also the number of sub-sub-pixels for black coverage are both victims of quantization errors during computations. For the case described here of twelve sub-sub-pixels per sub-pixel, this quantization error does not have an easily perceptible effect on the image for a human viewer, and the quantization errors can be ignored. If a print pixel is designed with a smaller number of sub-sub-pixels per sub-pixel, then these quantization errors become more noticeable in the image quality produced. The human eye is much more sensitive to brightness errors than color errors, so the priority is to repair brightness quantization errors. The ability to adjust the transparent photosensitive layer to black 105 allows an opportunity for correction.
    Petition 870190002500, from 01/09/2019, p. 28/95
    26/38 [00074] Consider a printing pixel with 5 sub-sub-pixels for each of the three colors (red, green, blue) and a fourth (and much smaller) white sub-pixel composed of a single white sub-sub pixel (WSSP). Such a printing pixel is a square printing pixel with 5 x 5 sub-sub pixels in total. The variation in black coverage over this single white sub-sub-pixel provides a mechanism to compensate for the brightness quantization error. This compensation can be performed, at the beginning of the algorithm, assuming that a single white sub-sub-pixel is black (even if the overall pixel color desired is pure white). Then when a brightness quantization error occurs, that white WSSP sub-pixel can be darkened to the desired gray scale level to overcome the quantization error (if more brightness is desired, a sub-sub-pixel covered with additional black is allocated instead of white coverage, so the difference made by darkening that single white sub-sub-pixel (WSSP). The following is a sample code for an ordering list for the print pixel configuration having 5 colored sub-sub-pixels and one white sub-sub-pixel per

    [00075] At that point, knowing how many of each 505 sub-sub-pixel to reveal for each 503 sub-pixel, and how many sub-sub-pixels to make black, the number of white sub-pixels is the rest:
    íotalWhiteCover = (3 * totalSubSub) - íotalBIackCover - totalRevealed [00076] Next, the sub-sub-pixels that must be opaque (white or black) are mapped in the 505 sub-sub-pixel grid that make up the 501 print pixel , step 135. A preference is given to having opacity located on the periphery of the printing pixel 501. This result is obtained by ordering the sub-sub-pixels with respect to their relative priority order to make an opaque sub-sub-pixel . Opaque sub-pixels are located according to that order of priority until all opaque sub-pixels have been assigned specific locations, if assigning opacity to a specific sub-pixel would make the sub-pixel to which that sub-sub-pixel belongs as having too few sub-pixels revealed from the print pixel grid layer 111, opacity is assigned to the next sub-sub-pixel in the order of opacity preference.
    At that point, the opacity map 123 was computed.
    [00077] Next, the black coverage map is computed. This calculation starts with determining the preference of
    Petition 870190002500, from 01/09/2019, p. 32/95
    30/38 brightness placement, step 137. To obtain sharp representation of brightness limits, source image 121 is analyzed to identify sharp brightness limits and to set a brightness positioning preference for each 501 print pixel; for print pixels that do not fall within a brightness limit, no brightness position preference is assigned.
    [00078] For each pixel in the source image 121 the direction and magnitude of the highest brightness contrast are identified by comparing adjacent pixels while ignoring the pixel brightness for which a brightness positioning preference is being determined.
    [00079] In this way, brightness contrasts are determined for the pairs up-down, left-right, up-right, down, right up-down. As an example, the brightness contrast for the above-below pair is:
    brightnessConírast (above, below) = abs (brightess (above) - brightnessfbelow)) [00080] If the highest brightnesscontrast for those adjacent pixel pairs is below a predefined limit, for example, 96/255, the brightnessPositioningPreference is adjusted in none. If the highest brightnesscontrast is above or equal to the limit, the dark side of the pair with the highest brightnessContrast is remembered as the brightnessPositioningPreference for the pixel.
    [00081] Next, a black ordering preference is computed, step 139. To determine the ordering of preference for placing black sub-sub-pixels, the 505 sub-pixels that make up the printing pixel 501 are ordered according to its relative proximity to
    Petition 870190002500, from 01/09/2019, p. 33/95
    31/38 brightnessPositioningPreference for that pixel. If the brightnessPositioningPreference is none, sub-sub-pixels 505 located over bright sub-pixels 503 are preferred, that is, green before red before blue, and secondary preference to sub-sub-pixels located at the edges of the print pixel 501 to reduce sensitivity to print misalignments. In this way, the ordered list of darkness of sub-sub-pixels is produced.
    [00082] Next, the opaque black sub-pixels are allocated to the sub-sub-pixels that make up the print pixel, step 141. Each nearby opaque sub-sub-pixel is allocated to a sub-sub-pixel in the order provided by ordered black list of sub-sub pixels. if as a black opaque pixel to be allocated it was not marked as opaque on opacity map 123, that subsub-pixel is not marked as black and the next sub-sub-pixel in the ordered sub-sub-pixel darkness list is considered. If the sub-sub-pixel was marked as opaque on the opacity map 123, it is marked as being black.
    [00083] Upon completion of this, process 110 determined the location of white sub-sub-pixels for the opaque-to-transparent layer 103 and black sub-sub-pixels revealed of the transparent-to-opaque layer 105. These maps are then translated to expose patterns for each of the photon sensitive layers 103 and 105, step 143, resulting in an exposure mask for white 125a corresponding to the transparent white-to-transparent layer and an exposure mask for black 125b corresponding to the transparent layer for black.
    [00084] Figure 11 is a flow chart illustrating a process 150 of using the masks produced from process 110 to create an effective image on an identity card 100.
    Petition 870190002500, from 01/09/2019, p. 34/95
    32/38
    First, identity card 100 and exposure equipment are aligned to ensure accurate exposure of photon sensitive layers 103 and 105 to produce the image, step 151. Misalignment could result in revealing the incorrect sub-sub-pixels from the print pixel set 111. Therefore, precise alignment is very important.
    [00085] Next, the white layer mask 125a is used to turn off sub-sub-pixel mask in the opaque-to-transparent layer 103 that must be converted from opaque white to transparent, step 153.
    [00086] The image area is then exposed to photons at the correct wavelength and intensity to convert from opaque to transparent, step 155.
    [00087] Next, the transparent to opaque layer 105 is converted from transparent to black by first unmasking the sub-sub-pixels that must be converted to black, step 157.
    [00088] The unmasked sub-sub-pixels are exposed after the photons necessary to cause the conversion from transparent to black, step 159.
    [00089] Finally, the image is fixed through a fixation step 161. The method by which the image is fixed, that is, the method by which the opaque to transparent layer 103 and transparent to opaque layer 105 are prevented from changing to other states, varies by material. The most direct case is for the opaque to transparent layer 103 to be targetable paint. It was found that certain target inks evaporate when exposed to UV laser. Thus, when the opaque to transparent layer 103 is transformed from opaque to transparent by
    Petition 870190002500, from 01/09/2019, p. 35/95
    33/38 removal of pigmentation from that layer, it is not possible to revert to being opaque. It is a transformation in a way.
    [00090] If the opaque to transparent layer 103 is a spiropyran layer, the layer can be made fixable by including a fixing material in the layer, for example, Ludopal as a photo-polymerizable polymer with benzoyl peroxide as a radical initiator. This layer 103 can be fixed by exposure to UV light in the range of 488 nm to 465 nm with a power of approximately 3.5 milliwatts / cm 2 for approximately 5 seconds. Suitable equipment includes a black beam lamp B-100 A, no. 6283K-10, 150W from Thomas Scientific of Swdesboro, New Jersey, USA. Alternatively, an opaque-to-transparent layer of spiropyran 103 can be fixed using heated rollers, for example, 3M Dry Silver Developer Rolls at 125 degrees Celsius at medium speed.
    [00091] Now returning to the equipment that can be used to produce an image 203 in an image area 205 of an identity card 100. Figure 12 is a block diagram of a first modality of a personalization station 351 to produce an image 203 in the manner described above. A .BMP 121 digital image is input to a 353 mask computer. The 353 mask computer can be a general purpose computer programmed to perform the computations of the process 110 described above in combination with figure 10. The 353 mask computer includes thereby a storage medium for storing instructions executable by a processor from the 353 mask computer. When the processor loads these instructions, which include instructions to perform process 110 operations, in its memory
    Petition 870190002500, from 01/09/2019, p. 36/95
    34/38 internal and executes the instructions regarding the .BMP image input 121, the mask computer 353 produces masks 125.
    [00092] Masks 125 are entered into a 355 process controller. The 355 process controller is programmed to perform process steps 150 in figure 11. In this way, the 355 process controller can use the masks to control a set of microspheres 357 in such a way that when a photon beam 359 emitted from a photon point source 361 is directed over microspheres 357 the latter redirects the photon beam exclusively over those sub-pixels of the image area 205 that must be exposed in according to masks 125. Controller 355 can also be programmed to control photon source 361 to cause exposure of appropriate duration for these sub-sub pixels. in an alternative modality, it uses a set for microfresnel lenses instead of the 357 micro mirrors. In such an modality, each Fresnel lens provides a focus on a specific sub-sub-pixel.
    [00093] Figure 13 is an alternative embodiment of a personalization station 351 'to produce an image 203 in an image area 205 of an identity card 100. In the case of personalization station 351', a controller 355 'is programmed to accept masks 125 to control a light array 363 that is composed of a plurality of light sources. The light array 363 produces photons at the appropriate wavelength and intensity to convert the photon-sensitive layers from corresponding locations in the 205 image area. In one embodiment, the photon beams produced by the light array 363 are focused through
    Petition 870190002500, from 01/09/2019, p. 37/95
    35/38 one or more lenses 365 to cause the trajectory of the photon beams over the appropriate sub-sub-pixel locations in the image area 205.
    [00094] Figure 14 is a flow chart of a 370 smart card life cycle extended to include the technology described here. In card manufacturing step 10, the print pixel grid 111 is printed on a substrate 107 of each card, step 11. This can, for example, be done using standard offset printing. Then the transparent to opaque layer 105 is deposited on the card, step 13. Next, the opaque to transparent layer 103 is placed on the card, step 15. And finally the card is laminated, step 17a. it should be noted that in some modalities of the identity card 100, the lamination step is performed after the image 203 has been produced on the card 100.
    [00095] The resulting manufactured card 100 has an image area 205 consisting of the print pixel layer 111, the transparent to opaque layer 105, and the opaque to transparent layer 103 all optionally under a laminate layer 109. The cards 100 can now be delivered to customers, step 20.
    [00096] It should be noted that for the 100 ”identity card modality illustrated in figure 3 (c) the ordering of the steps above can be somewhat reorganized.
    [00097] At customer locations, cards 100 can be customized for end users, step 30. This includes making an image of the end user on the card, step 31, in the manner described above by converting an image file into masks 125 that can be used to control
    Petition 870190002500, from 01/09/2019, p. 38/95
    36/38 equipment that exposes selected locations in the image area to photons that selectively reveal or hide sub-sub-pixels of various specified colors. After creating the image, it is fixed, step 33. Alternatively, the cards 100 can be protected against alteration by adding a filter that filters photons that would alter the photon-sensitive layers, for example, by applying a filter varnish to the card. In yet another alternative, an additional transparent layer is included between the top lamination layer 109a and the photon sensitive layers 103 and 105. This additional layer is also a photon sensitive layer. This additional layer, after being exposed to photon energy or heat, transforms from transparent to wavelengths that transform opaque layer into transparent 103 and transparent layer into opaque 105 into opaque for those wavelengths thereby blocking any attempts to alter the image 203.
    [00098] As described above, in some embodiments the change from opaque to transparent is based on ink evaporation from opaque to transparent layer 103. Therefore, the perso phase 30 can conclude with a lamination layer 17b after customizing the image area 205 The post-person lamination step 17b also provides an alternative opportunity to have a filter that blocks photons that could otherwise further alter the image 203, in which case fixation step 33 and lamination step 17b can be considered as one step.
    [00099] Finally, card 100 can be shipped to an end user 40.
    [000100] Thus, the smart card life cycle has been successfully modified to provide post customization
    Petition 870190002500, from 01/09/2019, p. 39/95
    37/38 shipping by placing an end user image on the card under a laminate thereby improving the personalization of the card while providing a high degree of tamper resistance.
    [000101] From the above it will be evident that a technology was presented above that allows personalization of sensitive items such as identification cards, bank cards, smart cards, passports, valuable papers, etc. in a post-manufacturing environment. This technology can be used to place images on such articles within a lamination layer that can be applied before or after the lamination layer has been applied. In this way, items, for example, smart cards, can be manufactured in a mass production mode in a factory setting and customized on relatively cheap and simple equipment at the customer's location. The technology provides a mechanism to thereby personalize items, such as smart cards, bank cards, identity cards, with an image that is tamper-proof.
    [000102] While the above description focuses on smart card customization, which is a field in which the technology described above is ideally suited, the smart card foundation here should only be considered as an example. The technology is also applicable to other devices and documents that benefit from secure personalization with an image. Some examples include ID cards, bank cards, smart cards, passports, valuables.
    [000103] Although specific embodiments of the invention have been described and illustrated, the invention should not be limited
    Petition 870190002500, from 01/09/2019, p. 40/95
    38/38 to the specific forms or arrangements of parts so described and illustrated. The invention is limited only by the claims.
