Abstract :
Visual secret sharing (VSS) schemes, providing secret communication services, are classified into two categories: visual-cryptography-based (VC) and random-grids-based (RG). As a friendly progressive version of VC-based VSS presented in 2008, it suffers the problem of pixel expansion which is innate deficiency of conventional VC-based VSS. In this paper, a new friendly progressive VSS scheme by random grids is proposed without this problem. To demonstrate the feasibility, the experimental results show the proposed scheme does work.
