Christian Cachin. Information­Theoretic Model for Steganography (An), IHW'98 - Proc. of the International Information hiding Workshop, April. 1998. [PS]   Abstract An information­theoretic model for steganography with passive adversaries is proposed. The adversary's task of distinguishing between an innocent cover message C and a modified message S containing a secret part is interpreted as a hypothesis testing problem. The security of a steganographic system is quantified in terms of the relative entropy (or discrimination) between PC and PS. Several secure steganographic schemes are presented in this model; one of them is a universal information hiding scheme based on universal data compression techniques that requires no knowledge of the covertext statistics. | Neil's Homepage | Steganography | JJTC Main Page | Send comments to nfj(at)jjtc(dot)com.
