- a fingerprint or fingerprint is the result of the affixing of a finger on a support.
- the pattern formed on the support consists of dermatoglyphs. Fingerprints are unique and characteristic of each individual.
- a "digital trace”, a more general term, is the result of contact between a finger and a support, the fingerprint being an example of a digital trace.
- the papillary traces (or their fingerprints) include fingerprints (or their fingerprints with automatic identification software spotting 150 to 200 characteristic points) and palm traces (traces of the palms of the hand spotted by 1500 to 2000 points characteristics).
- the digital trace can be:
- the trace comes from the sweat deposit (secretion of the sweat glands: 99% of water which while evaporating leaves in place salts and amino acids) and / or sebaceous secretions deposit (sebaceous glands) and / or
- the trace comes from the contact of a finger with a malleable surface (wax, putty ).
- the lines of fingerprints can be divided into three main types of patterns: arches (also called arches or tents), loops on the right or left and turns, whorls or swirls. These three types of footprints group together 95% of the human fingers: 60% for the loops, 30% for the spirals and 5% for the tents. We differentiate the patterns between them with the help of "singular points" on the loops, arcs or turns:

- the coded message integration means 145, coded positions and coded features in a digital matrix code define a matrix of dots representing the sequence of numbers of the code provided by the coding means 140.
- the message is integrated in a central square, whose resolution makes it an anti-copy mark (that is to say, whose degradation by the print noise, that is to say the generation of one-off, individually unpredictable errors, causing a point to be interpreted with an incorrect value, then copying can be measured to discriminate an original from a copy).
- the printing means 155 on or in the document 125 of the analog matrix code 130 is, for example, a printer or a marking means implementing a laser beam.

- the first step 205 is to capture an image of a document to secure against forgery and against changes.
- the captured image is entered in a software for extracting characteristic elements (measurements, ratios, contours or points, for example) or compression, which, during step 215, provides these characteristic elements.
- the positions of the extracted characteristic elements are marked on the document.
- the characteristic elements and their positions are coded.
- a message is encoded.
- a digital matrix code is constituted by integration of the encodings of the characteristic elements and their positions and the message.
- locations available on the document are determined to receive the printing of the matrix code. For example, during step 240, for each point of the image of the document, outside predetermined margins, the distance from this point to the nearest point carrying information is determined. Then the largest area with points for which this distance is greater than a predetermined distance is selected. For example, this predetermined distance is one twentieth of the length of the smallest side of the document. We then determine if this larger area may receive all the elements of the matrix code (for example 17 elements for the matrix code illustrated in FIG. 5).
- the predetermined distance is reduced, for example to one fortieth of the length of the smallest side of the document, and the search for the largest area is repeated.
- step 240 is repeated by determining, for each point of the image of the document, outside predetermined margins, the distance from this point the area of the nearest document that carries characteristic information processed in step 215.
- a form of the matrix code to be printed is determined. For example, during step 245, in the largest zone determined during step 240, the matrix code shapes in which the number of side common to two elements of the matrix code are decreasing are successively tested (for example, in the form illustrated in FIG. 5, there is 26 common side between the 17 elements of the matrix code). It is determined whether the largest area can contain the considered form. If not, we go on to the next form. If so, this form is retained for printing the matrix code.
- the digital matrix code is printed on the document of which an image was taken during the step 205, at the location determined during the step 240 and in the form determined during the step from step 245.
- step 240 a plurality of locations (from areas having the largest distance to information) is determined and, in step 245, a plurality of code part shapes are (forms that enter these locations).
- step 250 the code is printed in parts taking the locations determined in step 240 and the shapes determined in step 245.
- the control device 300 of the present invention illustrated in FIG. 3 comprises:
- the digital image capture 320 is similar to the means 120 except that it is configured to capture an image of sufficient resolution of the matrix code 330 so that it can be read.
- the means 335 for extracting characteristic elements is similar to the means 135.
- the decoding means 345 performs inverse functions of the coding means 140. However, the decoding means 345 decodes only the image characteristic elements and their coded positions. in the matrix code 330.
- the means 340 for checking correspondence between the contents and positions of the characteristic elements of the image captured by the capture means 320 and the characteristic elements encoded in the matrix code 330 determines a degree of similarity between these elements. characteristics and these positions, if this degree of similarity is greater than a predetermined limit value, it provides integrity confirmation information of the candidate document 325. Otherwise, it provides information integrity defect of the candidate document 325, meaning that its content or form has been altered, whether it is counterfeit or that ometrics encoded in the matrix code 330 do not correspond to the biometric data carried by the candidate document 325.
- the decoding means 350 performs inverse functions of the coding means 140. However, the decoding means 350 only decodes the message carried by the matrix code 330 and does this decoding only if a confirmation of integrity information is provided by the means 340 correspondence check. In addition, the decoding means 350 measures the noise carried by the copy protection code representing the message, for example in counting the error correction rate needed to read this message. The decoding means 350 determines the authenticity of the document as a function of the noise measured:
- FIG. 4 shows, for the verification of a document, that is to say the verification of its integrity and its authenticity, a step 405 of capturing an image of at least a part of the document, a step 410 for extracting characteristic elements from the captured image and their positions, a step 415 of capturing an image of a matrix code representing characteristic elements of an image and an additional message, a step 420 decoding the coded characteristic elements and their positions in the matrix code and a step 425 for checking correspondence between the contents and the positions of the characteristic elements extracted during step 410 and the contents and positions of the decoded characteristic elements during from step 420.
- step 425 If the match is checked in step 425, during a step 430, the message encoded in the matrix code is decoded and provides, for example, displayed.
- step 435 the noise carried by the copy protection code representing the message is measured, for example by counting the error correction rate necessary to read this message. Then the authenticity of the document is determined: If this noise is greater than a predetermined value, which depends on the resolution of the anti-copy code, the document is declared as a copy. Otherwise, the document is declared as authentic.
- the message represented by the anti-copy code represents or identifies a decoding key necessary for decoding the image characteristic elements coded in the matrix code. digital 330.
- the digital matrix code 330 represents or identifies a decoding key necessary for decoding the message carried by the copy protection code.

- correspondence check can, in this case, be performed visually by a user, for example after display on a screen, decoded characteristics elements.
- the noise carried by the anti-copy code representing the message is measured and compared to a predetermined limit value.
- This limit value is, for example, learned in a learning step (not shown) from the original 500 documents and copies made from these documents. Two clouds of noise values are thus obtained and a limit value is chosen between these clouds of values.
- the decoding of the anti-copy code 510 integrated in the matrix code 515 makes it possible on the one hand to determine whether the document 500 is a copy and, on the other hand, to obtain an additional message representing, for example, indications (time stamp, signatory name, biometric data of the signer, etc.) relating to the document 500 or to its signatory, sender, recipient or owner.

- the result of the hash function (or "hash” for "condensate) is used, in variants, filter to provide access to the reading of the message preserved by the anti-copy code.
- the hash of the fingerprint of an index is used to descramble the anti-copy code or the matrix code.
- the de-scrambling allows the authentication of the individual
- the de-scrambling allows the authentication of the document
- the application of the hash leaves the content (payload) of the readable code (the de-scrambling makes it possible to authenticate the physical legitimacy of the support)
