Abstract: Reversible data hiding in encrypted domain combines the dual advantages of encryption technology and data hiding technology, aiming to achieve privacy protection of data content on public channels,and reversible data embedding, so as to cope with the increasingly complex application requirements in the cloud environment. The research significance of reversible data hiding in encrypted domain is discussed from four application scenarios: encrypted data management, covert communication of intelligence, military collaborative operations, and technological integration innovation. Then, the reversible data hiding in encrypted domain is classified according to the operation relationship between data embedding and data encryption, and the technological development under different embed-ding frameworks is also reviewed. Furthermore, technical difficulties of reversible data hiding in encrypted domain are analyzed from four aspects, including embedding performance improvement, separability implementation, image encryption security, and application requirements for cloud environment. Finally, subsequent research directions are analyzed and prospected.

Key words: information security, reversible data hiding, cloud environment, image processing, encrypted domain
