In this paper we propose a new approach to protect video sequences while using selective encryption (SE) and reducing the encryption ratio (ER). Several methods of SE have been applied to video codec H.264/AVC in CAVLC mode in order to perform confidentiality, bit-rate, and data-size of protected video-sequences. In our scheme, SE-CAVLC is used but ER is decreased while preserving the confidentiality of the videos. Prediction error of H.264/AVC is used to spread a selective encryption through each frame, which allows the selection of just a part of the macro-blocks to encrypt. |
