Reversible Data Hiding in Encrypted Image via Joint Encoding of Multiple MSB and Pixel Difference

Reversible data hiding in encrypted image (RDHEI) has become a research hotspot, which can effectively protect content privacy. An RDHEI scheme based on the joint encoding of multiple MSBs (most significant bits) and pixel difference is proposed this paper. A block-based encryption method adopted owner side, securely contents while retaining spatial correlation within each block. By strategy MSB difference, redundancy bit plane sufficiently compressed to accommodate more additional data; thus, high embedding rate be achieved. According different kinds available keys, decryption extraction separably conducted receiver side. Experimental results show that our achieve higher than some state-of-the-art schemes.
