摘要：
For security of stereoscopic video, a video encryption and information hiding algorithm based on entropy coding is proposed. Firstly, with the analysis of Multi-view Video Coding (MVC), the physical mechanism of error drift is investigated. By applying the stereoscopic masking effect, the frames to be encrypted and the frames to be embedded are determined. Secondly, by using a Context-based Adaptive Binary Arithmetic Coding (CABAC) bin-string substitution technique, the encryption and data hiding of stereoscopic video are implemented. Experimental implementation reveals that the video stream has the format compatibility and the bit-rate remains unchanged after encryption and data hiding. The video quality degradation is negligible. The algorithm has significant advantages in computational complexity and rate increase.
