Forensic Marking for IP Protection

A video processing technique to deter unauthorized viewing or downloading of video footage while enabling traceability of leaks. The technique embeds a hidden forensic marker in some frames and a visible marker in others, creating an alternating pattern from the original video stream. If the video is leaked, the hidden marker can be detected to identify the specific leaked portion. The visible marker can also be checked to verify if it matches the hidden marker pattern, revealing whether the entire video or only a portion was leaked.

Security marker system with redundancy to improve accuracy and reliability. The system has two components, a forensic marker and a validation marker. Both markers contain unique sets of characteristics that correspond to data in a database. This allows independent validation of results obtained from the forensic marker. The redundant validation marker improves accuracy/reliability compared to just using the forensic marker. The markers can be separate components or built-in redundancy in the forensic marker.

Preventing the unauthorized distribution of copyrighted video content and tracking the illegal distributors using a forensic watermarking technique that allows real-time insertion and detection of high-resolution video watermarks. The technique involves generating a forensic watermark with a unique identifier based on content metadata, inserting it into the video, and storing the original video and watermarked video. When the video is played, the watermark is detected and checked against the stored version. If the watermark doesn't match, it indicates an unauthorized copy. The technique also involves storing transaction information when the video is requested. This allows tracking the origin of illegally distributed videos back to the original viewer. The real-time watermarking and detection allow catching video piracy in progress. The separate user and distributor watermarks prevent collusion attacks.

Real-time forensic watermarking method and system for digital content to insert user-specific watermarks in content as it is delivered to the user. The content server inserts different watermarks into the original content to create separate versions. It sends the fragmented versions to the user's device, which combines them in the correct order based on user info to create a personalized watermarked version. This allows dynamic user-specific watermarking without pre-processing or delay.
