A method of steganalysis of text data based on statistical analysis
Abstract
This article is about a steganalysis method of text data. It proposes a simple and effective approach to detect the presence of embedded information in text files. A message extracted from the text is checked for randomness by means of chi-square test. The method is based on the fact that message randomness reveals the presence of embedding.
