Abstract:Aiming at the secure, robust and perceptually invisible data hiding goal, a Discrete Cosine Transform (DCT) based blind video watermarking algorithm which is robust against collusion attack is proposed in this paper. This research work embeds the binary code acting as a digital fingerprint in the video frame that uniquely recognizes the authenticated user. The fingerprints are designed in the DCT domain that resist collusion and controls piracy. The confidentiality of the original frame is achieved by embeddin… Show more
