    A method and a device for signature verification, where an electric pulse train individual for every person in question is caused to be generated in that said person is allowed to move a pen comprising at its nib a light-emitting member and a light-sensitive member over a background, whereby an electric pulse train is caused to be emitted from the light-sensitive member in response to patterns on said background, and where said pulse train generated at a certain occasion is caused by means of a computer, processor or corresponding device to be compared with pulse trains generated earlier. The invention is characterized in that said pen at its nib comprises a writing pen or a ballpoint pen capable to bring about a line when the pen is moved on a support capable to write on, such as a paper document, and said pulse train is generated when the person at the writing of his/her signature with the pen nib crosses lines written earlier during the writing with the pen, and that the signature being in writing constitutes said background.

     The invention relates to an automatic, ke, in particular to a method for recognizing a signature and a device for its implementation.
    The purpose of the invention is to increase the reliability of signature verification.
    On league. 1 shows a sample signature; in fig. 2 - pulse sequence, created when writing the specified signature; in FIG. 3 - the tip of the writing instrument (pen); in fig. 4 is a block diagram of a device, which is the actual method proposed.
    Writing tool 1 (pen) contains (fig.Z) light source 2, for example, a diode, a light guide 3, a receiver 4, made in the form. phototransistor, light guide 5, wire - NICKY 6-9 and writing element 10.
    The block diagram of the device (FIG. 4) contains an input block 11, a block 12 and
    one
    13 memory, computer (computer) 14 and display 15.
    Pigaug instrument 1 is connected to input unit 11 (Fig. 4).
    The device works in the following way.
    When the writing instrument (pen) 1 is moved over the background consisting of light and dark areas, a signal is generated in the form of a sequence of electrical pulses at the output of the phototransmitter 4. This sequence of pulses goes through the input unit 11 to the computer 14 when the person being tested moves writing instrument on support. In the first phase, one person makes several personal signatures, which are memorized in block 12. Computer 14, which receives such a series of pulse laix. sequences programmed

    s
    van for comparison of these pulse sequences and simultaneous lumping of parts of the named pulse sequences., which are to a certain extent similar, Part - fragments, sections or entire pulse sequences. After such a comparison, 11 the computer 14 is programmed to store identical parts in block 13. In the second phase, after the said identical parts are stored, the computer 14 is programmed to draw a person's signature to compare the pulse sequence created with the corresponding parts stored in memory assessing the presence in the last created pulse sequence of parts corresponding to the stored parts and the degree of their convergence. When a similarity is found, the person who made the last signature is considered identical to human: the person who made several signatures in the first phase.
    In accordance with the invention, said pulse sequence is formed in a special way.
    It is assumed that the support that permits writing is a paper, plastic, etc., on which a writing or iGarikovy pen is able to leave a mark. Reliance, in particular, relates to documents, checks, official lists, etc., on which a person is asked to verify something by writing a personal signature.
    Thus, when the pen is moved on a support, it leaves behind a trace line. When a person puts his personal signature, the lines cross each other. This assumption is true in almost all cases. With each such movement, a pulse appears on the conductors 8 and 9 of the phototransmitter 4; as a result, a pulse sequence characteristic of each person is formed.
    The invention, in a manner, is based on the assumption that the named pulse sequence is formed when writing the signature, and the written out signature represents the named above background, i.e. source for pulses.
    Tla FIG. Figure 1 shows the ERIC signature, which may be a part of a full signature. The direction in which the pen moves while writing is indicated by arrows. FIG. 2 is a potential-time diagram illustrating the output voltage of the photo-transistor 4.
    The number O indicates the potential level, which is reached when the pen is detached from the support or when the pen illuminates the dark area on the support, i.e.
    when through the light guide 5 the phototransistor 4 does not receive light or it receives very little. Figure 1 indicates the potential level that is reached when light is reflected
    from the output of the light guide 3 using a support to the input of the light guide 5.
    The numbers 10P-106 (Fig. 1) denote intersections that occur when the pen moves in the direction indicated by the arrows; Figs. 2 illustrates the corresponding pulses. It has - with seven pulses with various 1.11 and time intervals between them. I.
    Additionally, .- two longer
    impulses exist at level 0, namely, pulses 107 and 108. P1 pulse 107 is formed because a person raises the pen after completing the writing of the letter E in the signature
    before writing the letter C, i.e. from point 109 to point 110. An impulse 108 is formed because a person lifts the handle between points 111 and 112.i
    The first first pulse sequence, i.e. the pulse sequence stored in the memory of the computer 14, and accordingly, only parts of it can be compared
    with the second pulse sequence, i.e. impulse sequence, formatted by a person during signature verification.
    Very high level of reliability
    it is possible to achieve even if only these pulses are partially compared, and at the same time the acceptance level can be kept high when the pulses are only partially compared. This is due to the fact that a person differently fulfills his signature, which depends on the prevailing mental state of a person.
    In most cases, however, a certain number of parts are very similar to the dependence on the soul and the influence of external factors.
     For these reasons, it is not the appearance of the signature that is of interest, but the pulse sequence that is. Section 4 is configured using the specified flat code.
    When analyzing such an impulse sequence, several parameters must be taken into account, as well as a combination of different parameters, in order to achieve the accuracy with which the signature must be made relative to the impulse sequences stored in the computer so that the acceptance level, i.e. it could be assumed that the verification took place ...
    In the first phase, a large number of pulse sequences are entered into block 12. Computer .14 is programmed to compare these pulse sequences according to various criteria with each other and select certain characteristic sections or sections of the pulse-; sequences, followed by memorization of selected sites or sections in block 13. Block 13 may also contain an identification card number, an account number, a particular person has the right to access a particular, pa, or other part of the data register. information.
    Thus, when verifying the signature, the subject again uses his pen to sign. The pulse sequence generated here is stored in block 12. Computer 14 can be programmed in a suitable, known manner.
    2. A writing instrument for verifying a signature, comprising a housing with a photodetector installed in it, the input of which is optically coupled to the output of the first light guide, the input of which is the information input of the writing instrument, which also In order to improve the reliability of verification, it contains a second fiber, the output of which
    comparing some part of the pulse-dz is the output of a writing instrument, a sequence stored in and a source of light, in particular block 13, with a part of the pulse meter bottom, the output of which is optically connected to the block the second fiber.
     12 memories. When comparing it is found that the pulse sequences or their parts are to a predetermined degree similar to each other, computer 14 is programmed to display a message that the verification can be considered completed, that the last written signature was made by the same person who previously signed the pulse that generated the pulse follower. on the first phase.
