( <i>n</i> , <i>n</i> ) Multi-Secret Image Sharing Scheme with Enhanced Quality Meaningful Shares

Abstract Traditional visual secret sharing (VSS) schemes that encrypt secret images into noise-like images have been extended to multiple secret sharing (MSS) schemes to share multiple secret images using meaningful shares. Due to poor visual quality, such schemes are vulnerable to attacks from intruders. In this paper, we propose an efficient (n, n) MSS scheme for sharing n secret images, where n cover images are embedded in n meaningful shares. The proposed scheme provides improved visual quality with higher sharing capacity. Security is enhanced by meaningful share images. Thus, the proposed scheme offers enhanced quality and efficiency while satisfying security criteria.
