Abstract EN
In order to effectively increase embedding capacity and completely extract the watermarking information in information hiding of encrypted images, a new reversible watermarking embedding algorithm based on rhombus prediction model and difference histogram shifting ideas is proposed.
Firstly, the images are pretreated according to rhombus prediction model.
Then, the watermarking information is embedded in encrypted images by effective combination of homomorphism encryption scheme and reversible watermarking techniques.
Finally, the watermarking information is completely extracted and the images are recovered based on computed difference histogram from left to right and from top to bottom.
So, the efficiency and reversibility are ensured when watermarking information is embedded in encrypted image.
Experiment results show that the proposed algorithm is simple and easy to realize, the embedding capacity is effectively increased, watermarking information is completely reversible, and the image can be recovered with no distortion.
