Abstract:

This work proposes a novel reversible image data hiding (RIDH) scheme over encrypted domain. The data embedding is achieved through a public key modulation mechanism, in which access to the secret encryption key is not needed. The encrypted data is embed into the image using Bitwise XOR operation. Then the image after embedding divides into block by Image block splitting method. At the decoder side, a powerful two-class SVM classi´Čüer is designed to distinguish encrypted and non-encrypted image patches, allowing us to jointly decode the embedded message and the original image signal. Compared with the state-of-the-arts, the proposed approach provides higher embedding capacity, and is able to perfectly reconstruct the original image as well as the embedded message.
