Biometric authentication method, corresponding authentication system, program and terminal

摘要

The method involves providing biometric authentication information (11) by an individual to be authenticated and an identifier forming an address information (10) designating sub-databases containing reference information representing the individual. The reference information corresponding to the individual is searched from a set of reference information stored by an authentication system based on the authentication information. A searching phase (13) of the reference information is performed on a subset of the set of the reference information, identified by the address information. Independent claims are also included for the following: (1) a system for biometric authentication of an individual to be authenticated from large number of individuals (2) a downloadable computer program product comprising a set of instructions of program code for carrying out the authentication method (3) a terminal for biometric authentication of an individual to be authenticated from large number of individuals.
