Ocular biometric authentication with system verification

摘要

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.

主权项

1. A biometric authentication system, comprising:
an image database comprising a plurality of images; a user database containing a plurality of user profiles, each user profile associated with a selected one of the images 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 for receiving asserted user credentials; an eye scanning module for obtaining ocular biometric data; a position detection module for detecting an eye position or eyelid position; an optics module including a first lens to be viewed with a left eye of a user and a second lens to be viewed with a right eye of a user; and an access control module in communication with the user database for obtaining a user profile associated with the asserted user credentials, in communication with a display device for displaying the image key associated with the obtained user profile only through one of the first and second lenses and displaying another image only through another of the first and second lenses, in communication with the position detection module for verifying the biometric authentication system by detecting whether the user is viewing the image key, and in communication with the eye scanning module for obtaining ocular biometric data and authenticating the user by matching the obtained ocular biometric data with the ocular biometric data record.
