A construction method of visual secret sharing schemes for plural secret images
Mitsugu Iwamoto and Hirosuke Yamamoto
- In this paper, a new method is proposed to construct a visual secret sharing scheme with a general access structure for plural secret images. Although the proposed scheme can be considered as an extension of Droste's method that can encode only black-white images, it can encode plural gray-scale and/or color secret images.
