Abstract: In terms of the problems of the traditional algorithms concerning the working nonfluncy of the distance education operating system and the drop-outs video playing, a perceptive encryption algorithm was proposed based on the advantages and disadvantages of the comprehensive induction of the traditional video encryption scheme and the characteristics of the H.264 video data. Furthermore, an experimental platform of distance education video was established to modify the kernel of Android system, aggrandize the video data flow processing bank and introduce the remote education receiving devices. When the video was displayed on the basis of the perceptive encryption, asterisks appeared. The video could be displayed by applying the decryption algorithm to the perceptive algorithm. And the Android system works smoothly, which indicates that the effective control of video encryption and video decryption could be achieved through the algorithm, and the system operation stability could also be guaranteed.

Key words: remote education, perceptual encryption algorithm, android operating system, copyright management
