Substitution-based linguistic steganography based on antonyms

Abstract

<span>The study of steganography focuses on strengthening the security in protecting content message by hiding the true intention behind the texts. However, </span><span>existing linguistic steganography approach especially in synonym-based substitution is prone to attack. In this paper, a new substitution-based approach for linguistic steganography is proposed using antonyms. The antonym-based stego-text generation algorithm is implemented in a tool called the Antonym Substitution-based (ASb). Evaluation of ASb was carried out via verification and validation. The results showed highly favorable performance of this approach.</span>
