摘要

Due to a rapid increase in copyright infringement, protecting secret information during transmission on the Internet is very important. More and more researchers have proposed solutions such as steganography, watermarking and data hiding schemes to solve these problems. Among these methods, the reversible data hiding scheme (RDH) is the most famous method. It not only extracts secret information from the stego carrier, but also recovers the original carrier. Therefore, in this study we propose an effective RDH in absolute mean block truncation coding (AMBTC) compression code, which uses joint neighborhood coding (JNC) to embed secret information and uses an exclusive OR operator to compute differences between the current value and the selected value. Experimental results indicate that our scheme has a satisfactory embedding rate and an appropriate stego file size using JNC and XOR.
