Abstract

Abstract: High Efficiency Video Coding (HEVC) encryption can be encrypted by syntax elements. To our best known, almost all of current scheme of HEVC encryption encrypt the whole video in order to obtain unviewable information. However, it cannot meet the needs of all customers. In many cases, users would like visible information in encrypted video to satisfy their requirements. Aiming at this demand, we propose a multi-level encryption scheme in which each level can obtain different amount of information. First, we use AES-CTR to generate a pseudo-random number sequence. Then, the main syntax elements in H.265 /HEVC encoding process are encrypted by a pseudo-random sequence. In the process, only one syntax element is encrypted at a time. We find that the encryption of the luma and chroma intra prediction model (IPM) and the scrambling of DCT coefficient sign can achieve multi-level encryption of visual information. The experimental results meet our expectations. Meanwhile, users can flexibly choose the encryption level according to their various requirements.
