The process comprises a data-acquisition phase with the creation of a database of multicomponent digital signatures constituting fingerprints of identity documents, linked to a central server relocated relative to a primary database comprising variable textual data and images of reference identity documents. A relocated checking phase of identity documents at a checkpoint comprises the digitizing of an identity document to be checked, the creation of a fingerprint of the digitized document, the comparison of the latter with the fingerprint of a document from the fingerprint database indexed with the same reference number and the sending of a message according to the result of the comparison.

Method and system for automatically checking the authenticity of an identity document

The method of indexing multimedia documents comprises the following steps: a) for each document identifying and extracting terms tconstituted by vectors characterizing properties of the; b) storing terms tin a term base comprising P terms; c) determining a maximum number N of desired concepts that group together the most pertinent terms t; d) calculating the matrix T of distances between the terms tof the term base; e) decomposing the set P of terms tof the term base into N portions P(1&#x2266;j&#x2266;N) such that P=P&#x222a; P. . . &#x222a; P. . . &#x222a; P, each portion Pcomprising a set of terms tand being represented by a concept c, the terms tbeing distributed in such a manner that the terms that are farther apart are to be found in distinct portions P, P, and the terms that are closer together are to be found in the same portion P; f) structuring the concept dictionary; and g) constructing a fingerprint base made up of the set of concepts crepresenting the terms tof the documents, each document being associated with a fingerprint that is specific thereto.
