研究分块隐写算法和湿纸码隐写算法的设计原理,设计了一种融合分块隐写原理和湿纸码隐写原理的新型隐写算法,并给出算法的详细设计流程及实现方法。通过分块隐写的设计策略,可以提高在图像信息中隐写算法的容量,而结合隐写码的设计思想,可以提高隐写算法的安全性。仿真实验测试表明,设计的新型隐写算法在性噪比、抗攻击能力和隐写容量等指标上均有较优的表现。

This paper studies the design principle of block steganographic and wet paper code algorithm; designs a new steganographic algorithm integrating block steganographic and wet paper code algorithm; and presents the design process and implementation methods in detail. Taking advantage of the block steganographic design strat- egy the steganographic algorithm capacity in image information can be expanded, and with steganographic code de- sign ideas, the algorithm security can be improved. The simulation tests indicate that this new steganography algorithm has a better performance in noise ratio, anti -attack capability, steganographic capacity and other indexes.
