Abstract : In the field of video protection, selective encryption (SE) is a scheme which ensures the visual security of a video by encrypting only a small part of the data. This paper presents a new SE algorithm for H.264/AVC videos in CAVLC mode. This algorithm controls the amount of encrypted alternative coefficients (AC) of the integer transform in the entropic encoder. The structural similarity (SSIM) is used to measure the visual confidentiality level of each video frame and to control the amount of encrypted AC. Moreover, a new psychovisual metric to measure the flickering is introduced, the so-called TSSIM. This method can be applied on intra and inter frame video sequences. Several experimental results show the efficiency of the proposed method.
