Title (EN) AUDIO DATA TRANSFER
(FR) TRANSFERT DE DONNÉES AUDIO
Abstract:
(EN) This application relates to the transfer of audio data, and in particular to the verification that data transmitted to a data processing module, such as voice biometric module (111), did originate from a microphone. A microphone authentication apparatus (204) is described having a first input for receiving analogue audio signals from a microphone transducer (201) and an analogue-to-digital converter (202) coupled to said first input for generating digital microphone data based on the received audio signals. A data authentication module (203) generates an authentication certificate (MAC) for certifying that the digital microphone data did pass via the authentication module. The authentication certificate is based on the digital microphone data (DM) and an authentication module key. An output module outputs a digital microphone audio signal based on the digital microphone data with the authentication certificate.
(FR) L’invention concerne le transfert de données audio, en particulier la vérification du fait que les données transmises à un module de traitement de données, tel qu'un module biométrique vocal (111), proviennent d'un microphone. L'invention concerne un appareil d'authentification de microphone (204) comprenant une première entrée permettant de recevoir les signaux audio analogiques d'un transducteur de microphone (201), ainsi qu’un convertisseur analogique-numérique (202) couplé à ladite première entrée permettant de générer des données de microphone numérique d’après les signaux audio reçus. Un module d'authentification de données (203) génère un certificat d'authentification (MAC) permettant de certifier que les données de microphone numérique sont passées par le module d'authentification. Le certificat d'authentification est basé sur les données de microphone numérique (DM) ainsi qu'une clé de module d'authentification. Un module de sortie génère un signal audio de microphone numérique d'après les données de microphone numérique avec le certificat d'authentification.
