Audio anagram: An information hiding technique using cover data rearrangement
Abstract
This paper proposes an audio information-hiding technique termed Audio Anagram, inspired by linguistic wordplay. The technique introduces a cryptographic mechanism analogous to an anagram, in which rearranged data remains perceptually plausible, thereby concealing the presence of the hidden message. The proposed method enables the extraction of secret audio data by reversing a mapping that rearranges the cover audio signal. This approach serves not only as a practically feasible method but also as a creative audio manipulation technique, allowing two distinct audio streams to coexist within a single signal.
