The invention relates to a method for enrolling data in order to verify the authenticity of a security datum, the method comprising implementing by data processing means of a server the steps of: obtaining a reference security datum, generating a first encoded datum by applying to the reference security datum an obfuscated fuzzy Hamming distance encoding procedure, determining from the reference security datum, a plurality of derived data of the reference security datum, generating a first random datum, and determining a second encoded datum such that a variable point comparison predicate parameterized by the second encoded datum and the first random datum is true when said variable point has as coordinates said derived data, storing on a data storage means of the server at least said first and second encoded data. The invention also relates to a verification method and a server for this purpose.

Methods for enrolling data in order to verify the authenticity of a security datum or for verifying the authenticity of a security datum

The present invention relates to a method of processing a transaction sent from a proof entity () connected to a verification entity ();

Method of processing a transaction sent from a proof entity

A method for strong authentication of an individual by a server and a connected client device, the client device having a candidate biometric data of the individual and an image from an identity document representing at least one photograph of the individual and one optical reader data visible on the identity document. A cryptographic footprint includes extracting, by analysis of the acquired image and the optical reader data, calculating a first data decoded by application of a decoding process to the candidate information and to a first encoded data, such that the first decoded data matches first random data if the candidate information matches a reference information representative of the appearance of the photograph, verifying that a cryptographic footprint of a first concatenation of the extracted optical reader data and the decoded data coincides with the first cryptographic footprint, and a reference biometric data and the candidate biometric data match.

Method for strong authentication of an individual

A method of authenticating an identity document based on an extraction, by analysis of an image acquired of the identity document, of candidate information representative of the appearance of a photograph such as depicted in the acquired image and optically readable data as depicted in the acquired image.

Method of authentication of an identity document of an individual and optionally authentication of said individual

The invention proposes a method for registering data from an individual's identity document (), the method being characterized in that it comprises implementing by data processing means () of a server () the following steps: (A) Receipt of a photograph of said individual visible on said identity document (), an optical reading data element of the identity document (), and at least one personal data element of said individual; (B) Extraction by analysis of said photograph from reference information representative of the appearance of said photograph; (C) Generation of a random string, calculation of an encoded data element by applying an encoding procedure to said reference information representative of the appearance of said photograph and said random string; (D) Storage on the server () data storage means () of:  The invention also relates to an authentication method and a server for this purpose.
