IRIS AUTHENTICATION DEVICE, IRIS AUTHENTICATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18217851 titled 'IRIS AUTHENTICATION DEVICE, IRIS AUTHENTICATION METHOD, AND RECORDING MEDIUM

Simplified Explanation

The patent application describes a method for authenticating a target using images of an authentication target's eye.

• Input a first image of the authentication target and a second image of the target's right or left eye.
• Determine whether the second image is of the left or right eye based on the first image.
• Output the determination result as left/right information associated with the second image.
• Detect an overlap between the region of the second image and a predetermined region in the first image.
• Calculate a verification score by comparing characteristic information related to the left/right information with iris characteristic information from the second image.
• Calculate a first weighted verification score by weighting the verification score with a detection result.
• Authenticate the target in the second image based on the first weighted verification score.
• Output the authentication result.

Original Abstract Submitted

The disclosure is inputting a first image captured an image of an authentication target; inputting a second image captured an image of a right eye or a left eye of the target; determining whether the second image is of a left eye or a right eye of the target based on information including the first image, and outputting a determination result as left/right information in association with the second image; detecting an overlap between a region including the second image and a predetermined region in the first image; calculating a verification score by comparing characteristic information that are related to the left/right information with iris characteristic information calculated from the second image, and calculating a first weighted verification score obtained by weighting the verification score with a detection result; and authenticating a target in the second image based on the first weighted verification score, and outputting an authentication result.
