| Abstract(in English) | The visual cryptography scheme (VCS) is a type of secret sharing scheme for images.The VCS uses matrices called basis matrices to generate shares, which are partitioned information for the images.In this paper, we focus on the VCS, in which multiple image information appear as a share or combinations of shares, and propose a method for constructing the basis matrices using the Boolean satisfiability (SAT) technique.Also, basis matrices constructed by the SAT technique are evaluated in terms of pixel expansion. |
