Abstract
System and process for audio authentication of an individual or speaker including a processor for decomposing an audio signal received at the sensor into vectors representative of the speaker to be authenticated for transforming the super-vector V of the speaker resulting from the concatenation of the vectors associated with the said speaker into binary data 1001100 . . . 0 taking as an input the mean super-vector M resulting from the mean super-vector, and comparing the super-vector V of the speaker with the mean super-vector M, the said binary data thus obtained being transmitted to a module for extracting the speaker authentication taking as an input the public keys Kpub(l) in order to authenticate the speaker and/or to generate a cryptographic key associated with the speaker.
