Popis
Shrnutí:A great many algorithms of video encryption have been proposed nowadays with the necessity of data rights management, especially the selective video encryption algorithms, which ensure the security of the information and meanwhile reduce the data to encrypt. The residue data, intra-prediction modes, inter-prediction modes and motion vectors are key elements that are usually partially or completely selected to encrypt to keep the security. In this paper, a new encryption algorithm that encrypts different elements according to different intra-prediction or inter-prediction modes for the H.264 standard is proposed. This novel algorithm keeps format appliance and has little impact on compression. Most importantly, it has flexible security levels with different applications.
