Abstract
Pixel expansion has been a major issue of visual secret sharing (VSS) schemes. A number of probabilistic VSS schemes with minimum pixel expansion have been proposed for black-and-white (binary) secret images. This paper presents a probabilistic (n, n)-VSS scheme for grayscale images. Its pixel expansion is significantly smaller than that of previous methods. The construction of the shadow images (shares) is based on the Boolean XOR operation. © 2008 Springer-Verlag Berlin Heidelberg.
