Abstract (in Japanese) (See Japanese page) 
(in English) An audio secret sharing scheme is a variant of secret sharing schemes in which a secret and shares are acoustic information. In previous work on audio secret sharing schemes, it is hard to reproduce the secret in physical space whereas they can achieve perfect secrecy. This drawback is due to the requirement that sound wave interference is necessary to be realized with high accuracy.
In this paper, we introduce a new security criteria such that it is considered to be secure if secret information cannot be recognized by human acoustic sense. Under our new security criteria, we
propose a new method of audio secret sharing schemes which does not use wave interference but is based on frequency dividing. Experimental results show that our new method offers easy reproduction of secret in physical space and actually realizes an audio secret sharing scheme.
