Summary Data hiding is widely used for concealing secrets in images so that senders can securely transfer these secrets to the receivers. In data embedding schemes, the image quality, hiding capacity, and compression ratio as well as the security of the hidden data are all critical issues. Instead of using traditional data encryption techniques to encrypt secret data in the preprocessing phase, this...
Reversible data hiding is a special algorithm that not only guarantees the confidential data will be extracted accurately but also allows the original cover image to be reconstructed without distortion after the confidential data are completely extracted. This paper proposes a new index compression and reversible data hiding scheme based on side-match vector quantization (SMVQ) and search order coding...
