Abstract (en)

[origin: FR2911021A1] The method involves encoding randomly chosen points of a polynomial of degree n into k code words of an error correction code, and dividing a stable and ordered representation of reference biometric data of a user into k parts, where k is equal to 16 and n is equal to 8. K pairs of values are calculated such that one pair comprises reference comparison between one of the code words and one of the parts of the representation, and an image of the code word by hash function. Independent claims are also included for the following: (1) a method of regenerating a secret from current biometric data of a user (2) a device for representing a secret from biometric data of a user (3) a device for regenerating a secret from current biometric data of a user (4) a device for capturing biometric data of a user (5) a computer program comprising code portions for executing a secret representation method (6) a data storage unit comprising a computer program for executing a secret representation method (7) a computer program comprising code portions for executing a secret regeneration method (8) a data storage unit comprising computer program code instructions for executing a secret regeneration method.
