Reversible Image Data Hiding with Homomorphic Encryption and contrast Enhancement

摘要：

　　This paper proposes a novel reversible data hiding algorithm with image contrast enhancement based on homomorphic public key cryptosystem.The additional data is embedded based on histogram shifting after preprocessing procedure.Then the image is encrypted using public key and side information is embedded.On the receiver side, the image with contrast enhancement is obtained directly after image decryption using private key.Due to the correlation between adjacent pixels, date extraction and image recovery can be implemented.To our best knowledge, it is the first reversible data hiding in encrypted image algorithm with image contrast enhancement.Experimental results have demonstrated the feasibility and effectiveness of the proposed method.
