SECURE IRIS AUTHENTICATION USING VISUAL CRYPTOGRAPHY

Abstract

Biometrics discusses automatic ways to find a person or verify a person's identity based on physical or behavioral factors. Visual cryptography is a private sharing system in which a secret image is enclosed in a cell that independently reveals that there are no facts about a unique private image. Since the biometric template is stored in a single database, due to security threats the biometric template can be altered by the attacker. Ifthe biometric template is changed by an official person then they will not be allowed to access the source. To address this problem visual cryptography schemes can be used to comfort the iris template. Visual cryptography offers a first-of-its-kind approach to assisting such security concerns and additional coverage. Especially with the rise of human laptop contact, the discovery ofthe eye world has drawn good attention over the past decade. In this experiment, a country eye detection device was introduced basically based on round hough transform (cht). First, a face-to-face shot is removed from the gray-degree photographs. After some advanced steps, the life patterns of the circular structure are searched within the of cht. The life of the iris circular structure is searched image created by the use inside the image with the eyes with the help of a circular hough remodel
