Sound Steganography using Shamir Secret Sharing Scheme

Transmitting information in a secure way is now both a challenge in everyday life and a beautiful area for research. The type of information may intended to hide may include sensitive information of institutions or private health information of ordinary people. Several algorithms and combination of algorithms have been proposed and tested. Here in this work we propose to hide an image in several other images after it is separated in pieces and then reconstruct it in a similar way to the Shamir secret sharing scheme. We will do this in to steps: firstly, by attaching n chunks of the image into n other images; and secondly, these combined images will be embedded to n different audio files. Any random collection of k (k<n) audio files will be used to reconstruct the original image.
