摘      要：Reversible data hiding in encrypted image(RDHEI)is a widely used technique for privacy protection,which has been developed in many applications that require high confidentiality,authentication and *** RDHEI methods do not allow high embedding rate while ensuring losslessly recover the original ***,the ciphertext form of encrypted image in RDHEI framework is easy to cause the attention of *** paper proposes a reversible data hiding algorithm based on image camouflage encryption and bit plane compression.A camouflage encryption algorithm is used to transform a secret image into another meaningful target image,which can cover both secret image and encryption behavior based on“plaintext to plaintext*** edge optimization method based on prediction algorithm is designed to improve the image camouflage encryption *** reversible data hiding based bit-plane level compression,which can improve the redundancy of the bit plane by Gray coding,is used to embed watermark in the camouflage *** experimental results also show the superior performance of the method in terms of embedding capacity and image quality.
