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。
The communication model of known information hiding system is analyzed. A new theoretical model based on information theory is proposed. The proof of hiding capacity under no attack condition is obtained and the model is discussed. The new model mainly considers the robustness of the existing information hiding system, comprehensively integrates the information hiding embedding, detecting and attacking models, and improves the previous information hiding theoretical model without considering the testing model.
