DETECTION OF DEEP FAKE VIDEOS BASED ON DIGITAL SIGNATURE

摘要

Technologies are generally described to provide authenticity for a video signal. Audio and video components of the video signal may be captured along with a verification signal distinct from the audio and video components of the video signal and transmitted by a physical device on or near a speaker captured in the video signal. The audio and/or the video component of the video signal may be signed with the verification signal prior to transmission to provide authenticity of the video signal. An authentication accessory device on or near the speaker may detect an audio or video component of the video signal, generate an audio or video verification signal based on the detected component, and transmit the audio or video verification signal to be captured with the video signal. At the receiver side, the verification signal may be decoded and the received video signal authenticated based on the decoded verification signal.
