High Volume Secure Data Hiding In Video

This paper proposes a Multi-Stream Cipher Stegnographic technique for high volume and secure data hiding in digital video and images. The proposed technique enables high rate of data embedding along with provisioning of confidentiality, integrity and authenticity security services. Embedding is carried out in spatial domain utilizing multiple stream ciphers for embedding signature information. Signature data is first processed using an advance symmetric cipher. The cryptogram thus obtained is then spread over the individual colour bands of each pixel of every video frame using multiple cryptographically secure pseudorandom bit generators. This results in an extremely secure, imperceptible and alteration detectable steganographic scheme supporting high volume data embedding including picture-in-picture and video-in-video. An analysis of the proposed scheme against available steganalysis methods has also been carried out.
