A novel selective encryption scheme for H.264/AVC video with improved visual security

作者：

Highlights：

• A selective encryption scheme for H.264/AVC video with format compatibility and better visual scrambling effect is proposed.

• The encryption can resist known sketch attacks compared to other existing methods.

• The encryption method is suitable for both compressed video and raw video.

• Adaptive frame encryption keys based on the initial key and the statistical characteristics of each frame are employed to enhance security.
