A biometric authentication system includes an image database and a user database containing user profiles. Each user profile is associated with a selected image in the image database as an image key and with an ocular biometric data record obtained from an eye of the associated user. A user input terminal receives asserted user credentials, an eye scanning module obtains ocular biometric data, and a position detection module detects an eye position or eyelid position. An access control module communicates with the user database for obtaining a user profile associated with the asserted user credentials, communicates with a display device for displaying the image key associated with the obtained user profile, communicates with the position detection module for verifying the biometric authentication system by detecting whether the user is viewing the image key, and communicates with the eye scanning module for obtaining ocular biometric data and authenticating the user. |
