摘要：
The thresholding scheme in which a person can decode the encrypted data with an important information in the agreement of other members has been extended to the visual data by visual cryptography. But with the limitation of visual cryptography in the representation of information, some problem is encountered in application, This paper proposes a method to overcome the problem by introducing an optical technique to the visual cryptography.
