摘要
分析了已知信息隐藏系统的通信模型,提出了建立在信息论基础上的理论新模型,得出了无攻击情况下隐藏容量的证明,并对该模型进行了讨论。新模型重点考虑了信息隐藏系统实际存在的鲁棒性,全面综合了信息隐藏的嵌入、检测和攻击模型,对以往信息隐藏理论模型中没有考虑检测模型做出了改进。
In this paper,the author analyze the already communication model of information-hiding system,and intro-duce the own theoretic model based on information theory.Then the author give a proof of the hiding capacity under the condition of no attack,and discuss the characteristic of the model.This model think about more the real exist robust of information-hiding system,and entirely colligate embedding,testing and attacking model in one.It improve on already information-hiding theoretic model which don't consist of testing model.
