SYSTEM FOR AUTOMATIC VERIFICATION OF BIOMETRIC DATA SIGNALS, ESPECIALLY GENERATED BY A SPEAKER

摘要

The invention concerns a method for automatic verification of signals (Y) of biometric data associated with at least one individual called a client defined by a determined identity. The processing is distributed between an embedded system (5) and a host terminal (4), the said host terminal (4) performing indexing (32) of the regions containing characteristic vectors (y(t)) obtained from the said signals (Y) in a space of characteristics representative of the said signals (Y), using a partition (RX) or a set of partitions (RiX) of said space, associated with the said claimed or assumed identity and transmitted by the embedded system (5) and the said vectors (y(t)) and, the said embedded system evaluating a global score (S) from the said series of indices (<>(t)<) or of index vectors ([?>i,(t)<]) transmitted by the said terminal.
