摘要

隐写通道是一种通过将隐藏的数据以难以检测的方式嵌入到另一个文档中来传输隐藏数据的方法。本文分析了一种基于纠错码的无噪声隐写信道通信数据隐藏模型。证明了两个相应的香农定理，并讨论了码的平均覆盖半径作为隐写应用的重要参数。香农定理推广了D'yachkov(2006)在二元模型中得到的结果。

On error-correcting codes for a steganography channel

A steganography channel is a method of transmitting hidden data by embedding it into another document in a way that is difficult to detect. In this paper, we analyze a model of data-hiding for communication via noiseless steganography channel by application of error-correcting codes. Two corresponding Shannon theorems are proved, and the average covering radius of a code is discussed as an important parameter for steganography applications. The Shannon theorems generalize the results obtained in D'yachkov (2006) for the binary model.
