YouTube Stego
YouTube has become an extremely popular video sharing website. We ask and answer the question: is it possible to convey hidden message though this medium. Considering that the videos uploaded to YouTube undergo format conversion as well as compression and that the embedder has no control over or knowledge of the parameters involved in the process, this is a tough challenge. Specifically, we propose a novel temporal-DCT based spread spectrum data hiding scheme that can survive YouTube compression. The method is designed to reduce the decoded bit error rate of the messages while keeping the distortion to the original video low.
