A Reversible Data Hiding Scheme in AMBTC Compression Code Using Joint Neighborhood Coding

Steganography is a well-known technique used to protect important secret information by embedding the secret data into a cover multimedia file, such as video, still images and audio. This study proposes a reversible data hiding method, which uses a joint neighborhood coding (JNC) technique to hide secret data in AMBTC compression code. A reversible data-hiding scheme proposed by Wang was modified by this proposed method. We apply an exclusive OR operator and modified JNC algorithm to provide higher capacity. The experimental results demonstrated that the proposed method improved capacity by more than 3% over Wangs scheme in terms of embedded rate (ER).
