Abstract:
With the development of the emerging applications, watermarking methods require a new type of constraints.
In fact, robustness to malicious attacks and processing time reduction have became two important constraints which must verify a watermarking approach. In this paper, a new scheme of digital watermarking for video security is proposed. This scheme is based on dynamic multiple-sprites. These last ones allow obtaining
robustness in front of collusion which presents a dangerous attack for marked video. First, original video is divided into groups of images, and then a sprite will be generated from each group. Finally, the signature will be inserted in the low bits of the obtained sprite and marked frames will be generated from the marked
sprites. Experimental results show that the proposed scheme is robust against several attacks such as collusion, compression, frame suppression and transposition, and geometric attacks. In more, processing time of watermarking is reduced.
