Due to increasing security requirements, digital videos need to be encrypted to maintain confidentially, integrity and availability. This paper proposes data embedding in H.264/AVC video where the embedded data is restored without knowing the original video content. In this manner, confidentially is preserved. The property of H.264/AVC code, the codeword of the intra-prediction modes, motion vector differences and residual coefficients are encrypted with the stream ciphers. User may hide additional data in the encrypted domain by using code word substitution method. Data can be restored in encrypted domain or in the decrypted domain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
