Information Hiding Scheme Based on LDPC coding

This paper proposes a new information hiding scheme in images via LDPC coding. Generally, resisting the bits attacking is nearly impossible for the conventional information hiding system. In this article low-density parity check codes are introduced into the information hiding system because of the better performance of their own. We provide the information hiding system based on the LDPC coding as well as the belief propagation decoding algorithm, and analyze the performance of the results. The simulation results show that the proposed information hiding system based on LDPC codes can achieve the good error rate performance and the apparent robustness can be taken on
