Reversible data hiding in encrypted images with separability and high embedding capacity

作者：

Highlights：

• The image is encrypted by modular addition with addition homomorphism.

• After encryption, the correlation between adjacent pixels can be preserved.

• The prediction technology can effectively improve the prediction accuracy.

• Through a control factor, the embedding capacity can be flexibly adjusted.
