Abstract
Nowadays, due to the increasing need for cloud storage and cloud computing services, digital images need to be kept confidential in order to secure the privacy of individuals' information. Since the currently available codomain reversible data masking techniques are based on gray images, this paper introduces a data masking approach using color image channel correlation to achieve codomain reversibility. In the encryption stage, the security and homomorphism of encryption are achieved through XOR encryption and block scrambling. The data hiding processed by making full use of the texture information data of the reference channel to predict the pixel data more accurately, and an adaptive prediction error expansion technique is used to embed the encrypted information into the R, G, and B channels. The experimental results prove that the method has better security and better performance than the existing algorithms.
