Abstract

Digital videotape at times requirements near be stored and processed in an encrypted layout to keep sanctuary and seclusion. Used for the principle of comfortable information with tampering appreciation, it is basic to complete information thrashing in these encrypted video. Into this system, information thrashing into encrypted sphere personal of decryption protects the privacy of the restful .In reckoning, it is additional inventive present decryption follow by data thrashing along with encryption. Into this serious newspaper, a original format of information thrashing openly in the encrypted description of H.264/AVC videotape river is projected, which include the subsequent three part, videotape encryption, information embed, and information removal. By analyzing the possessions of H.264/AVC code, the codeword’s of intraprediction and the codeword’s of enduring coefficients are encrypted with torrent ciphers. Then, a in turn hider may surround supplementary data in the encrypted domain by using code word substitution procedure, without perceptive the original videotape contented. In instruct to adapt to different application scenarios, information extraction can be done whichever in the encrypted domain or in the decrypted domain. Videotape dossier extent is harshly conserved even after encryption and data embed. Tentative grades comprise established the probability in addition to good organization of the planned methods.
