Abstract

As the compression technique spread on the Internet, data hiding combining with compression techniques is a hot property in recent years. In this paper, a reversible data hiding (RDH) scheme for Absolute Moment Block Truncation Coding (AMBTC) compressed image is proposed. In the proposed scheme, according to the four kinds of situations which the secret data combine with the bitmap value, we provide some rules to embed data by use the mean value and the absolute moment. Experimental results and analysis demonstrate that, the proposed method can achieve high capacity with low distortion. Besides, the proposed method is very simple and can be easily applied to real-time transmission due to its lower computational complexity.
