Secure Multimedia Data using H.264/AVC and AES Algorithm

The demand of multimedia information is increasing rapidly. Therefore, multimedia security has become one of the most aspects of communications with the continuous increase in the use of digital data transmission. Many approaches are there to secure multimedia information. In this paper Selective Encryption is proposed along with compression on multimedia information. This paper proposed a new system of video encryption. The proposed system aim Selective Encryption is performed by using the Advanced Encryption Standard (AES) algorithm and Compression is performed using H.264/AVC Standard. The system includes two main functions; first is the encoding/encryption of video stream, through the execution of two processes (the input sequences of video is first compressed by the H.264/AVC encoder, and the encoded bit stream (I-frame) is partially encrypted using AES block cipher). And the second function is the decryption/decoding of the encrypted video through two process (specify the encrypted I-frame stream, decryption of the I-frame, and decoding with H.264/AVC decoder).
