Dual Authentication Using Face Match Ambiguity and Partial Passwords
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in securely authenticating users when face authentication results in multiple potential identities, requiring additional manual input of user identification information to confirm identity.
Innovation Solution
A dual authentication process involving face recognition followed by partial or full password entry based on collation results, where face authentication identifies multiple candidates, requesting partial password entry to confirm identity, and full password entry if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face authentication is used to authenticate users, then authentication convenience is improved, but authentication security deteriorates when multiple candidate identities are found
Solution Approach 1:
The authentication process is segmented into two distinct phases: face authentication for initial identification and password authentication for final verification. When multiple candidate identities are found during face authentication, the system segments the authentication process by requiring additional password verification to resolve the ambiguity and ensure secure authentication.
2Reliability
If additional authentication methods are required when multiple identities are found, then authentication security is improved, but user burden increases
Solution Approach 1:
The system applies partial action by requiring password authentication only when necessary (when multiple candidate identities are found), rather than always requiring full authentication procedures. This partial application of additional authentication methods maintains security enhancement while minimizing unnecessary user burden in cases where face authentication alone is sufficient.
3Measurement precision
If the system determines multiple candidate identities from face authentication, then authentication accuracy is improved, but authentication time increases
Solution Approach 1:
The system performs preliminary face authentication to identify candidate identities before requiring additional password verification. This preliminary action filters and pre-sorts potential users, so that when multiple candidates are found, the subsequent password authentication can proceed more efficiently by focusing only on the relevant candidates rather than requiring complete re-authentication from scratch.
Data Source
AI summary
An information processing system includes circuitry. The circuitry collates authentication target face information with registered face information to generate a collation result. The authentication target face information is acquired by reading face information of a person to be authenticated. The registered face information has been registered in advance in association with user identification information. When multiple pieces of user identification information are found based on the collation result indicating multiple pieces of registered face information satisfying a predetermined authentication condition, the multiple pieces of user identification information of the user identification information being associated with the multiple pieces of registered face information of the registered face information, the circuitry requests entry of an at least partial password and authenticates the person to be authenticated, based on entered password information and multiple pieces of password registration information, which are stored in association with the multiple pieces of user identification information.
