Abstract

We propose two novel visual two-secret sharing schemes in this paper. The major difference between the previous and our approaches is that the two secrets are revealed by superimposing shares at different distances. In our schemes, two secret images would be encoded into two shares with different sizes, and the two secrets can be revealed by superimposing the two shares at two different superimposition positions. The distant superimposition for decoding enhances the flexibility of the visual cryptographic system.

This research was supported in part by the Ministry of Science and Technology, Taiwan, under Grants MOST 102-2221-E-130-005 and 103-2221-E-130-002-MY3.
