Reversible data hiding in encrypted images using cross division and additive homomorphism

作者：

Highlights：

• Host image is divided into crosses.

• Homomorphic encryption is with no data expansion.

• Data hiding is directly processed in encrypted domain.

• Real reversibility is realized.

• Difference histogram is shifted several rounds.
