Chestega: chess steganography methodology

Steganography is the science and art of avoiding the arousal of suspicion in covert communications. This paper presentsChessSteganography (Chestega), a novel methodology that exploits popular games like chess. Chestega conceals messages in chess related covers such as training documents, game analysis, news articles, etc. Unlike contemporary approaches, Chestega does not exploit noise to embed a message nor produce a detectable noise. Instead, authenticated data can be employed in the cover which makes it resilient to comparison attacks. Chestega is also a public approach that neither relies on the secrecy of its technique, nor need to employ a stega‐key. The paper demonstrates the feasibility of employing authenticated Chess Cover that is generated by Chessmaster 8000. Chestega is further validated through steganalysis.
