Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deepfake technologies are rapidly evolving and challenging to detect in real-time applications, particularly in network-based communication systems, where deepfakes are generated and rendered instantaneously or with minimal latency, and existing detection algorithms are inadequate.
Innovation Solution
Utilizing invisible and inaudible watermarking techniques as in-band steganography to authenticate the source capture camera and microphone by encoding steganographic watermarks into media streams, which are detectable using AI-based neural networks and survive editing, and leveraging public certificates for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If deepfake detection algorithms are used, then deepfake detection capability is improved, but detection accuracy and reliability deteriorate in real-time applications
Solution Approach 1:
The patent embeds steganographic watermarks into media content at the source (camera/microphone level) before distribution. These watermarks contain authentication information that proves the media was captured by the legitimate device. This preliminary action shifts the detection burden from analyzing complex deepfake generation processes to verifying simple watermark presence, enabling reliable real-time detection.
Solution Approach 2:
The patent introduces steganographic watermarks as an intermediary authentication mechanism between the capture device and the media content. Instead of directly analyzing the complex deepfake generation process, the system uses these watermarks as a trusted intermediary that carries authentication information, simplifying the detection process while maintaining high reliability in real-time applications.
2Ease of manufacture
If traditional computer graphics and animation methods are used, then content creation capability is improved, but production time and computational resources increase
Solution Approach 1:
The patent uses steganographic watermarks as digital copies of authentication information that can be embedded into media content without altering the actual visual or audio content. These watermarks are imperceptible copies that carry authentication data, allowing for rapid verification without the computational burden of analyzing the entire media content for deepfake characteristics.
3Reliability
If steganographic watermarks are embedded in media streams, then authentication reliability is improved, but media stream complexity increases
Solution Approach 1:
The patent applies steganographic watermarks at the local level within the media stream, embedding authentication information directly into the media data structure itself rather than adding separate authentication layers. This local embedding approach maintains authentication reliability while minimizing the increase in overall system complexity, as the watermarks are integrated seamlessly into the existing media format.

AI summary
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.
