An Overview of Text Steganalysis

Abstract

AbstractWith the rapid development of the Internet, network information security is progressively under menace. Text steganography is one of the key reasons to affect information content security. It aims to hide confidential information in text carriers in a concealment system. In case that text steganography is used by criminals, malicious information can easily be transmitted through the Internet without being discovered by a third party. In contrast, text steganalysis is an effective technique to solve this problem by detecting whether a text carrier contains secret information. This paper presents an overview of current text steganalysis methods starting from 2006. We discuss the basic text steganalysis model and compare the pros and cons of these algorithms, hoping to offer some perceptions and motivations for future research directions.KeywordsInformation securityText steganographyText steganalysis
