High Capacity Reversible Data Hiding Scheme based on AMBTC for Encrypted Images
View through CrossRef
<p>Reversible data hiding for encrypted images is a technique that allows for exact extraction of embedded data and precise reconstruction of the encrypted image to its original version. In this paper, we propose a novel, reversible data hiding technique based on an absolute moment block truncation coding (AMBTC) algorithm for encrypted images. In the proposed scheme, each selected block is represented by an AMBTC code to vacate space to embed data after image encryption. Upon obtaining the encrypted image with the embedded data, the receiver can separately extract the embedded secret data and also recover the cover image losslessly. The experimental results for the proposed scheme achieved excellent performance. The proposed scheme is significantly superior to state-of-the-art schemes in terms of embedding capacity and image quality.</p>
