数据冗余空间中的掩密术安全性

Security of Steganography Based on Space of Redundancy Data

分析了目前掩密术的研究的理论和掩密术安全性评估理论,指出了目前掩密术研究框架的部分局限性和现有掩密术安全性理论的不足。在视觉冗余的基础上提出了基于数据冗余性的掩密术定义和掩密术安全评估准则。

After analyzing the actual steganographic theoretics and the theoretics of evaluation of steganographic security,some localization in steganographic framework and theoretics of steganographic security are found out. Besides visual redundancies, defines of the stegangraphy and evaluation of steganographic security base on data redundancies were given out.
