Evauation for Optical Visual Cryptography Encryption by using Optical Correlator

광상관기를 이용한 광 시각 암호의 암복호 평가

Optical visual cryptography was proposed by conjunction of the optical theory with the cryptography. However, it had some difficulties. The problems occurred in the process of transferring data processing system from visual to optics. Therefore, it is appropriate to approach these problems in terms of optics. The results show that the optical visual cryptography system has both the effectiveness and reliability as well as real-time implementation property.
