Enhanced Matrix-Based Secret Image Sharing Scheme.
IEEE Signal Processing Letters（2012）
Abstract
Recently, Rey proposed an efficient (2, n) matrix- based secret image sharing (MSIS) scheme based on simple binary matrix operations. However, the threshold property of Rey's (2, n)-MSIS scheme is compromised. Elsheh and Hamza showed a weakness that if the ranks of the singular matrices used in Rey's scheme are not low enough then one can retrieve the secret information from only one shadow image....
