Title (EN) AUDIO DATA TRANSFER
(FR) TRANSFERT DE DONNÉES AUDIO
Abstract:
(EN) This application relates to transfer of microphone data from a microphone (101, 102, 102a, 201) to a processing module, such as voice biometric authentication module (111) in a secure manner, such that the receiving module can trust that the received audio is genuine. An authentication module (203) is configured to receive microphone data (DM) representative of an audio signal received at the microphone (201), and generate from the microphone data, authentication data (DA) for certifying that the microphone data did pass via the authentication module. The first authentication data (DA) comprises information relating to distinguishing characteristics of the audio content of the microphone data and may, for instance be an acoustic fingerprint of the audio content. The authentication data, may be cryptographically signed or encrypted and sent with the microphone audio to allow a receiver to verify that the audio is genuine and the content has not been substantially altered. The process may be robust to processing of the data that results in imperceptible changes in the audio content.
(FR) L’invention concerne le transfert sécurisé de données de microphone depuis un microphone (101, 102, 102a, 201) vers un module de traitement, tel qu'un module d'authentification biométrique vocale (111), de façon à ce que le module de réception puisse confirmer l'authenticité du signal audio reçu. Un module d'authentification (203) est configuré pour recevoir des données de microphone (DM) représentant un signal audio reçu au niveau du microphone (201) et générer, à partir des données de microphone, des données d'authentification (DA) permettant de certifier que les données du microphone sont passées par le module d'authentification. Les premières données d'authentification (DA) comprennent des informations relatives aux caractéristiques distinctives du contenu audio des données du microphone. Il peut s'agir, par exemple, d'une empreinte acoustique du contenu audio. Les données d'authentification peuvent être signées ou chiffrées de manière cryptographique et envoyées à l’aide du microphone audio pour permettre à un récepteur de vérifier que le signal audio est authentique et que le contenu n'a pas été sensiblement modifié. Le processus peut être robuste au traitement des données, ce qui engendre des changements imperceptibles du contenu audio.
