Study of Selective Video Encryption for the H.264 Standard
Qiu Hua Wang, Xing Jun Wang · Applied Mechanics and Materials · 2013
Video encryption has been widely researched in digital right management in recent years, especially selective video encryption. Selective video encryption has been the main trend with the development of compression coding methods, which selects an important subset of the comparative large compressed video data to encrypt in order to satisfy the real-time features and ensure the security of the video at the same time. In this paper, according to a particular evaluation criterion we proposed, we mainly analyze several selective video encryption algorithms based on the H.264 standard. Through the analysis we find out how to select the different vital data sets of the video to encrypt according to various security levels and applications.
