| Abstract(in English) | We consider a visual cryptography sharing scheme with cyclic access structure for n secret images and n shares, where two consecutive shares decode one secret image. This secret sharing scheme can be constructed by using Droste's method. However the contrast of its scheme is 1/(2n). In this paper, a new construction of such a secret sharing scheme is given, and its contrast is 1/4 for n ≧ 4 and 1/6 for n = 3. It is also shown that this contrast is sharp for every n. |
