Abstract

In this paper, we propose a new secret sharing scheme (SSS) [1] for audio signals, called as “Binary audio secret sharing (BASS).” SSS is an encryption method and produces n shared data from an original data to hide useful information. Applying SSS to audio communications on the Internet can help to make it more robust against theft and the tapping of information. Thus, we focused on the 1-bit audio format and applied SSS to 1-bit audio signals to realize audio secret sharing. Moreover, we propose a method to make each shared data heard as its intended sound.
