A Robust Anaglyph 3D Video Watermarking based on Multi-sprite Generation

Collusion presents a malicious attack for video watermarking techniques. In the case of anaglyph 3D video, this attack is not yet considered. In fact, only several watermarking techniques were proposed for this type of media and they are not robust against dangerous attacks such as MPEG compression and collusion. In this paper, a robust anaglyph 3D video watermarking technique is proposed. It is based on multi-sprites as a target of insertion. This allows obtaining a robustness against collusion attacks. First, several sprites are generated from original video. Then, a hybrid embedding scheme based on the least significant bit and the discrete wavelet transformation based method is applied on every sprite to insert signature. This improves invisibility and robustness against usual attacks. Experimental results show a high level of invisibility and a good robustness against collusion, compression and against additional attacks such as geometric and temporal attacks.
