摘要
本文基于对RS掩密分析技术的分析,利用矩阵编码技术对现有的空域LSB掩密算法提出了改进,改进后的算法可以在一定程度上抵抗RS攻击,从而进一步提高了LSB算法的安全性。
An improved LSB steganographic algorithm using matrix encoding on the spatial domain is put forward in this paper. The improved algorithm can resist RS steganalysis in some degree so that the security of LSB algorithm is improved.
