A visual cryptography based system for sharing multiple secret images
Shang-Kuan Chen · International Conference on Signal Processing · 2007
A Visual Cryptography (VC)-based system for sharing multiple secret images is proposed. Several weighted transparencies are generated so that people can reveal multiple secret images by stacking qualified subsets of some transparencies together. The transparency with relatively larger weight decides which secret image will be revealed. The proposed method has the following characteristics: decoding without computation, multiple secret images recovery, max-weight dominance, and quality-control design.
