Abstract:	In traditional visual secret sharing (VSS) scheme, the pixel expansion is a drawback which not only increases the transmission cost, but also distorts the recovered secret image. This paper proposes a visual secret sharing scheme which hides a secret into two share images without pixel expansion. It provides high quality of recovered secret image. The experimental results show the stacking result of share images in our scheme is smoother than others. Copyright © 2009 ACM.
