| Abstract(in English) | We developed an audio secret sharing scheme for 1bit-audio, Binary audio secret sharing(BASS), in which information of an original 1bit-audio signal is shared among k kinds of 1bit-audio signals heard like white noises. To obtain the original 1bit-audio signal, all of the k shared ones are necessary. Any k - 1 of them give no information about the original. This scheme was developed based on an existing visual secret sharing scheme for a binary image. In this report, we present a new technique for BASS to divide the original into shared decoy signals that are specifically intended but totally different from the original. This technique can provide k - 1 of the shared signals with any intended (desired) sounds without loss of secrecy. |
