Separable and three-dimensional optical reversible data hiding with integral imaging cryptosystem

Abstract

Reversible data hiding in encrypted domain (RDH-ED) is an important and effective technical approach for security data management of cloud computing, big data and privacy protection. This paper proposes a three-dimensional (3D) optical reversible data hiding (RDH) with integral imaging cryptosystem. The secret data is encrypted and embedded into the cover image. The receivers can decrypt the cover image and secret data with a reversible or lossless manner, respectively. The simulation experiment and results show that the data embedding rate can be increased to one. Besides, the quality of image decryption is quite high. The technique boasts the advantages of high data embedding rate, security level and real-time capability.
