A reversible data hiding in encrypted image based on additive secret sharing with adaptive bit-plane prediction

With the rapid development of 5G network, protecting multimedia data security has attracted a lot of attentions, and Reversible Data Hiding in Encrypted Image (RDHEI) has become a research hotspot, since it has the ability of hiding information while protecting the privacy of original cover images. RDHEI remains a challenging task to improve the embedding capacity under the premise of real reversibility. In this paper, we propose a RDHEI scheme with multiple data hiders based on Additive Secret Sharing (ASS) and Adaptive Bit-Plane Prediction (ABPP). First, ASS and bit-plane separation techniques are developed to encrypt an original image. It can encrypt an original image into n encrypted image shares with an encryption key and send each encrypted image share to one data hider. Then, we propose a Several-Parts-Disposable Strategy (SPDS) which is developed to generate the encrypted secret data with multiple data hiders. SPDS makes our scheme have the ability to resist collusive analysis and cooperative attacks. Finally, each data hider can embed encrypted secret data independently using ABPP embedding strategy. Furthermore, our scheme is separable and can be applied to multiparty copyright protection. In addition, we present a Shared No Key (SNK) based on secret sharing, which costs much lower computation than the literature works proposed SNK-type schemes by using homomorphic encryption. The experimental results and theoretical analysis show that our scheme is secure, high capacity and significantly outperforms previous schemes.
