摘要：将隐写过程从信道的角度进行描述,提出了一种新的隐写信道模型。该模型把隐写信道分为载体编码-噪声信道、攻击信道和编码-攻击信道。在此模型中,把错误概率和检测率作为失真约束,运用博弈论的方法分析了博弈双方在不同失真约束条件下的隐写容量。最后,给出了一种普遍情况下的信道分布服从高斯分布时的隐写容量的大小与基于博弈论的隐写容量估计的关系。
This paper presents a new stego-channel model by describing steganograph via channel.This model divides the stego-channel into cover encoder-noise channel,attack channel,and encoder-attack channel.In this model,the probabilities of both error and detection are taken as distortion constraints.By using game theory,this paper analyzes the steganographic capacity under the different distortion constraints between the two game players.Finally,this paper gives the steganography capacity and its relations of the game conditions for the case that the channels distribute is Gussian distribnte.
