Latest Patents

One of Oren Keidar's latest patents is a method for verifying the authenticity and integrity of an ordered sequence of digital video frames. This innovative approach allows for the embedding of digital signatures based on a secret key and the video content of respective frames. The signatures are cleverly camouflaged within the transform coefficients of the video data, specifically in areas corresponding to motion. If there is sufficient motion to accommodate all signature bits, a supplementary technique is employed to embed signatures in high-texture areas of the frame. Additionally, a fallback method is available for embedding in a predefined default zone. This process can be applied in a single pass, enabling real-time operation. Verification occurs during decoding by comparing the embedded signatures with those calculated anew using the same embedding method.
