Reversible data transmission, visible watermarking and steganography schemes that can be employed along with multimedia applications. However, these methods are susceptible to quantization errors provided by standard image/video compression standards. In this work we present a secured data transmission using novel reversible visible watermarking scheme for H.264/AVC encoded video sequences. The proposed approach reversibly embeds the residual information that will then be used by the decoder to recover the original image or video frame. The residual information is losslessly compressed using the Gzip Deflector algorithm to minimize the information to be embedded and reduce the distortion provided by RCM. The compressed information is then encrypted using the 128–bit Advanced Encryption Standard (AES). Furthermore we add security in this work if the key does not match we provide irrelevant information or unwanted data’s to the decoder. And finally we compared our proposed work with existing state of art.
