摘要：提出了一种基于数字图像的新的隐写信道模型.在该模型中,考虑隐写分析器的作用和载体与隐秘体的相似性,引入错误概率和检测率作为失真约束条件.运用博弈论,把隐写过程看成编解码方与攻击方的博弈,给出了隐写博弈的双方在不同失真约束条件下的隐写容量,并对容量结果进行了分析.
This paper presents a new model of stego-channel based on the digital images. It takes account of the steganalysis and similarity between cover-image and stego-image, considering the probability of error and probability of detection as distortion constraints. It applies game theory to steganography. It regards the eneoder-deeoder and attacker as the two players in the game, analysing the steganographic capacity under different distortion constraints. At last, it discusses the results of the steganographic capacity base on the game theory.
