Abstract

Identification method using data in a database that are distributed in at least a first group of data and a second group of data, a comparison being made using first of all the biometric data in the first group and then, in the event of failure of the comparison, using the biometric data in the second group, the distribution of the data between the groups being modified according to a number of validated identifications stored for each user, the first group comprising the data of the user comprising a number of validated identifications greater than a predetermined threshold over a predetermined period and identification system for implementing this method.

Claims11

Dependent claims

A method for identifying persons from at least one database that is hosted on a computing unit and contains identification data of users, including biometric data relating to biometric characteristics of the users, said biometric characteristics being of a predetermined type and the identification data contained in the database being distributed in at least a first group of identification data and a second group of identification data, the biometric data of the identification data of the first group relating to the same predetermined type of biometric characteristics as the predetermined type of the biometric characteristics to which the biometric data of the identification data of the second group relate, the method comprising:

capturing and coding by computer, at a predetermined identity check site, biometric characteristics of a candidate for identification in order to form biometric data of the candidate, the biometric characteristics of the candidate being of the same predetermined type as the predetermined type of the biometric characteristics to which the biometric data of the identification data of both the first group and the second group relate;
comparing and executing a program comparing the biometric data of the candidate with the biometric data of the identification data of the first group;
and
validating the identification if the comparison is successful, and then, in the event of failure of the comparison, comparing the biometric data of the candidate with the biometric data of the identification data of the second group;
and
validating or rejecting the identification according to the result of the comparison.
