US 12,645,806 B2 · Visual and audio output authentication in avatar systems

Abstract

A method for countering digital impersonation and unauthorized digital or audio usage due to a rise of deep-fake technologies is described. The method employs biometric authentication to ensure user authenticity in real-time during avatar or voice recording. Unique watermarks are generated at predetermined intervals and embedded into audio and/or video outputs. Device integrity can be additionally verified through device attestation, verifying both hardware and firmware integrity of the visual and audio systems. The device attestation may generate a device authentication key which can be combined with a user authentication key based on the biometric authentication to generate a combined watermark. Accordingly, real-time verification tools allow for the authentication of the watermark, ensuring ongoing content authenticity.

Dependent claims

A method comprising:

at each of a plurality of instances during recording of video or audio content by a user,
performing one or more biometric authentication operations to authenticate the user;
performing device attestation to verify integrity of at least one of a camera or audio system of a computing device of the user;
responsive to verifying the integrity of at least one of the camera or audio system, generating a device authentication key;
and
responsive to successful authentication of the user, embedding a cryptographic watermark into the video or audio content associated with the instance, the cryptographic watermark generated based at least on a combination of a user authentication key and the device authentication key to form a compound watermark representing continuous presence of the user during the recording.

3 more elements

One or more processors comprising:

processing circuitry configured to perform operations comprising:
at each of a plurality of instances during recording of video or audio content by a user,
performing one or more biometric authentication operations to authenticate the user;
performing device attestation to verify integrity of at least one of a camera or audio system of a computing device of the user;
responsive to verifying the integrity of at least one of the camera or audio system, generating a device authentication key;
and
responsive to successful authentication of the user, embedding a cryptographic watermark into the video or audio content associated with the instance, the cryptographic watermark generated based at least on a combination of a user authentication key and the device authentication key to form a compound watermark representing continuous presence of the user during the recording.

4 more elements
