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.

Abstract: The invention relates to a method of identifying a subject person 5 by comparing at least biometric data of the subject person with biometric data 14, 15, 16 of reference people previously recorded in a database 3. According to the invention, the comparison of the biometric data of the subject person 5 with the data of each reference person is performed by means of a first algorithm or of a second algorithm presenting different performance ratings, and, for each reference person, the comparison algorithm is selected on the basis of at least one selection criterion specific to each reference person.
