This paper presents a scheme that hides secret audio in cover audio on the basis of robust digital signature to preserve not only hidden communication but also content integrity and non-repudiation of the secret audio. Authentication of the scheme is flexibly measurable, and the measurement value is in correspondence with the sense of human hearing precisely. Experimental results show that the proposed scheme provides highly robust authentication against content-preserving degradations and high level of distinct authentication between content-destructive degradations.
