Zusammenfassung:The aim is to propose a system based on encryption of compressed video bit streams and hiding privacy information to protect videos during transmission using H.264/AVC. To maintain security and privacy video needs to be stored and processed in an encrypted format. Here, data hiding is done directly in the encrypted version of H.264/AVC which includes the following three parts i.e, H.264/AVC video encryption, data embedding and data extraction. choas encryption is used to encrypt/decrypt the secret data before/after data embedding/extraction. The simulated results shows that the methods used provide better performance interms of computation efficiency, high data security and video quality after decryption. The parameters such as mean square error, peak signal to noise ratio, correlation and structure similarity index are evaluated to measure its efficiency.
