Abstract

In this paper, a video encryption algorithm based on MPEG4 codec is proposed, which combines encryption process with MPEG4 compression process. This algorithm is composed of two parts: VOP (Video Object Plane) encryption and VOL (Video Object Layer) encryption. In VOP encryption, the intra-encoded VOP is encrypted by inter-block permutation, the intra-encoded code blocks are encrypted by bit-plane permutation and coefficient sign encryption, and the other code blocks are encrypted by motion vector encryption. In VOL encryption, the basic VOLs are encrypted while others left unchanged. It can obtain high speed, for only parts of VOLs are encrypted. And it supports direct bit-rate control, which means that the encrypted images can also be decrypted correctly after recompression or bit-rate conversion. What's more, it is more robust to transmission errors than traditional ciphers since the errors causing in the encrypted bit-stream cannot spread out. These properties make it suitable for secure multimedia transmission over network, such as Video-on-Demand systems, multimedia communication networks, mobile multimedia or wireless multimedia networks, and so on.
