确保湿纸隐写术中的消息嵌入

Ensuring message embedding in wet paper steganography

Daniel Augot, Morgan Barbier, Caroline Fontaine

摘要:

伴随式编码是由Crandall在1998年提出的一种通过使用有界解码将消息秘密地嵌入到覆盖介质中的方法。在2005年,Fridrich等人引入了湿纸码,通过使发送者能够根据覆盖介质和消息的性质锁定覆盖数据的某些成分来提高嵌入的不可检测性。不幸的是,几乎所有现有的方法解决有界解码综合征问题,或没有锁定组件有一个非零的概率失败。在本文中,我们介绍了一种随机的伴随式编码,它保证嵌入成功的概率为1。我们分析了这个新方案的参数的情况下,完美的代码。

英文摘要:

Syndrome coding has been proposed by Crandall in 1998 as a method to stealthily embed a message in a cover-medium through the use of bounded decoding. In 2005, Fridrich et al. introduced wet paper codes to improve the undetectability of the embedding by nabling the sender to lock some components of the cover-data, according to the nature of the cover-medium and the message. Unfortunately, almost all existing methods solving the bounded decoding syndrome problem with or without locked components have a non-zero probability to fail. In this paper, we introduce a randomized syndrome coding, which guarantees the embedding success with probability one. We analyze the parameters of this new scheme in the case of perfect codes.
