Data hiding has a vital role to play in information security. Using a data hiding technique, secret information is hidden into cover digital content. Compression techniques and data hiding techniques received much less attention from the research community and from industry than cryptography. In past research many data hiding and image compression techniques has been developed, it works indepen...

Reversible data hiding can guarantee that the original image can be recovered from the marked image without any distortion. In this paper, an efficient multilevel reversible data hiding algorithm for video sequences is presented. Since the gray level distribution of the difference map is Laplacian, the peak point of the distribution thus leads into high data hiding capacity and good image quali...

This framework propose a new video data hiding method that makes use of erasure correction capability of Repeat Accumulate codes and superiority of Forbidden Zone Data Hiding (FZDH). Selective embedding is utilized in the proposed method to determine host signal samples suitable for data hiding. This method also contains a temporal synchronization scheme in order towithstand frame drop and inse...

Reversible data hiding technology has currently attracted great attention recently. Using reversible data hiding methods, original cover images can be recovered losslessly from the cover image embedded information. In this paper, spatial reversible data hiding schemes based on histogram modification of difference images are discussed, in which the pixel gray values of difference image are alter...
