1. A method for strong authentication of an individual comprising:
(a) acquisition of a candidate biometric data for the individual and an image acquired from an identity document representing at least one photograph of the individual and one optical reader data visible on the identity document;
(b) by analysis of the image acquired from the identity document, extracting:
a candidate information representative of the appearance of the photograph as depicted in the acquired image; and
the optical reader data as depicted in the acquired image;
(c) calculating a first decoded data by application of a decoding process to the candidate information representative of the appearance of the photograph and to a first encoded data, wherein the first decoded data matches a first random data if the candidate information representative of the appearance of the photograph matches a reference information representative of the appearance of the photograph; and
(d) after the calculation of the first decoded data, verifying a first condition if a coincidence exists between:
a first candidate cryptographic footprint, wherein the first candidate cryptographic footprint is a cryptographic footprint of a first concatenation of the extracted optical reader data and of the first decoded data; and
a first reference cryptographic footprint, wherein the first reference cryptographic footprint is a cryptographic footprint of a first concatenation of the optical reader data of the identity document and of the first random data,
and a second condition if a reference biometric data matches the candidate biometric data of the individual; and
(e) if the first condition and the second condition are verified, performing an enrollment of an authenticator.
