Ying Shen, YE Yin-lan · 2010
This paper applies visual cryptography for copyright protection. A multiparty scheme is presented for coowners of digital image. The basic concepts of visual cryptography are explained at first. Then by comparing with reference, a scheme for coowners is described. Next, key points in schemes are listed including halftone and progressive algorithms. At last examples are listed to show the whole procedure.
