Verifiable Secure Secret Image Sharing Scheme

Angel Rose A, Sinu Maria Kurian

Abstract: Many visual secret sharing schemes for digital images have been developed in recent years. The new progressive secret sharing scheme for grayscale images proposed in this paper is based on a combination of bit-plane slicing of an image and equation based secret sharing scheme. First, n*n secret image and n*n cover images are decomposed into bit-plane images. Then higher bit-plane images of the both are utilized to produce shadows. The proposed scheme progressively recovers the secret. After collecting all shadow images, the secret image can be completely recovered.
