Integrated algorithm for block-permutation-based encryption with reversible data hiding

This paper proposes a Block-Permutation-Based Encryption (BPBE) method with Reversible Data Hiding (RDH). In the proposed algorithm, Histogram Shifting (HS) is used for RDH, and the BPBE method is utilized for encryption. The BPBE method performs four processes for encryption, namely, block scrambling, block rotation/inversion, negative-positive transformation, and the color component shuffling. The proposed algorithm is implemented on the concatenated image from a large database. Therefore, the number of the divided blocks can be increased, and the color scrambling of the encrypted image is increased. Consequently, the resistance against Jigsaw Puzzle Solvers (JPSs) could be improved. This algorithm consists of different hierarchical steps for the data embedding and the encryption. Therefore, the proposed algorithm can be suitable for the hierarchical access control system, where the permission is granted according to the various access rights.
