Abstract(in Japanese) (See Japanese page)
Abstract(in English) In this paper we first extend the steganography system model which Cachin proposed so as to admit errors. Based on this model, we introduce a new perfectly secure steganography scheme, one-time hash steganography, with which one can hide a secret bit into any cover-message that satisfies certain condition (partial recomputability). Finally, with the existence of one-time hash steganography system, we show that there exists a perfectly secure steganography system with given cover-message if and only if the cover-message source is partially recomputable to its sender.
