General Access Structure Secret Sharing in Matrix Projection

Abstract

Image Secret Sharing is a technique which provides security to confidential images by dispersed storages. General access structure image secret sharing provides flexibility for deciding qualified subsets of participants which can reconstruct the original secret image. Non qualified subsets of participants cannot get any information about original secret image. This paper proposes general access structure image secret sharing based on matrix projection. The experimental results show high accuracy, high security and less overhead in the network due to highly reduced size of image shares.
