Fault-Tolerant Visual 2-Secrets Sharing Scheme
Abstract— In 1994, Noar and Shamir proposed the basic visual secret sharing scheme (also called visual
cryptography) to solve a part of the security problem. Visual cryptography is to encrypt a secret image into
two meaningless random images, called shares, such that it can be decrypted by stacking these two shares
without any calculations. In practice, there would be problems in alignment when staking these two shares by
hand. Besides, share two secret images in the same time will enhance the functionality of the scheme.
Therefore, this study proposed a new visual secret sharing scheme which encrypt two secret images into two
shares in the same time, and it is not necessary to align the shares precisely. Both theoretical analysis and
simulation results demonstrate the effectiveness and practicality of the proposed scheme.
