Biometric Authentication Error Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems do not provide clear notification of the reason for authentication failure, making it difficult for users to understand the situation when they are not authenticated.
Innovation Solution
An information processing apparatus and method that includes a matching unit for biometric information, a determination unit for usage authority, and an output unit that provides first error information for failed matches and second error information for lack of usage authority, enabling users to understand the authentication failure reason.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the authentication device only outputs generic error information for authentication failure, then the device complexity is reduced, but the user understanding of authentication failure reasons deteriorates
Solution Approach 1:
The authentication failure reasons are segmented into distinct categories (biometric information not registered, usage authority not granted, both conditions met). The output unit provides different error information messages for each category, allowing users to understand the specific reason for authentication failure without requiring complex diagnostic mechanisms.
2Loss of information
If the authentication device provides detailed error information for all authentication failures, then the user understanding of authentication failure reasons is improved, but the device complexity increases
Solution Approach 1:
Different error information messages are provided for different local conditions of authentication failure. The determination unit evaluates specific local conditions (biometric registration status, usage authority status) and the output unit responds with appropriately tailored messages for each condition, avoiding the need for a complex universal error handling system.
3Reliability
If the authentication device determines authentication failure based on multiple conditions, then the authentication reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The output unit provides feedback to users in the form of specific error information messages that correspond to the actual reason for authentication failure. This feedback mechanism helps users understand what went wrong and what actions they need to take, maintaining ease of operation while ensuring reliable multi-condition authentication determination.

AI summary
An information processing apparatus in the present invention includes: a matching unit that matches biometric information acquired from a user requesting use of a management target with registered biometric information of each of a plurality of registrants; a determination unit that determines whether or not a registrant with which a matching result is that the matching is successful out of the plurality of registrants has usage authority for the management target; and an output unit that, when the matching result from the matching unit is that the matching failed, outputs first error information, and when it is determined in the determination unit that the registrant with which the matching result is that the matching is successful does not have the usage authority, outputs second error information different from the first error information.
