Abstract: With the arrival of many sophisticated video editing technologies, it becomes significantly difficult to trust the correctness of the video information. There are many cryptographically secure ways of video transmission. The proposed scheme includes encryption, data hiding and tampering detection using the embedded data. The proposed method includes the following three parts- H.264/AVC video encryption ,data embedding and data extraction for tampering detection. A selective encryption is performed in the compressed domain. Encryption and data hiding make use of the compression parameters. Two sensitive parameters namely intra prediction modes (IPM) and motion vector difference(MVD) are selected for encryption . The data hiding is performed by codeword substitution technique where the codewords of levels are used. The data embedded is used for tamper detection.The scheme ensures both format compliance and strict file size preservation even after encryption and data hiding.
