Secret Image Sharing Based on Transform Coding

The main challenges facing secure image sharing tasks are the increase of sharing volume and sharing-control flexibility. In this book a novel scheme based on transform coding has been developed to perform secret image sharing in the case when the secret image is a colored image with enough sharing control features and as minimum as possible shares sizes. The main signal decomposition attribute of the transform is utilized to divide the secret image into uncorrelated shares, and each share will be separately encrypted
