Abstract :

This paper 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. A powerful two-class support vector machine (SVM) classifier is designed to distinguish encrypted and non-encrypted image patches, allowing us to jointly decode the embedded message and the original image signal.The proposed scheme has several advantages over the state-of-the-art RIDH schemes. First, it provides higher embedding capacity. Second, it is able to perfectly reconstruct the original image as well as the embedded message. Third, it is more secure, as it does not require access to the secret encryption key.Extensive experimental results are provided to validate the superior performance of the proposed scheme. The results show that the proposed scheme can achieve higher embedding capacity, better image quality, and higher security than the state-of-the-art RIDH schemes.
