Inventors include Hanes, M. , David; Singh, Vivek, Kumar; and White, David, C. Jr..
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: Techniques for utilizing invisible and/or inaudible watermarking techniques in media streams (e.g., video and/or audio streams) as a form of in-band steganography to authenticate the source capture camera and/or microphone to prevent deepfakes in network-based communication systems. User device(s) may establish cloud-based connections to a network- based communication system hosting media stream(s). An encoder of a watermarking component of a user device may receive video/audio data directly from a camera/microphone thereof and encode the video/audio data with watermark(s) representing a signed signature. A decoder of a watermarking component of a recipient user device and/or another device associated with the communication system may extract the watermarks and authenticate the signed signature using public certificate(s) associated with the sending user device to validate authenticity of the capture source(s) of the sending user device and that the video/audio data has not been modified since the time of capture.
