Authentication apparatus, authentication system, authentication method, and authentication program using biometric information for authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication systems for multi-function peripherals (MFPs) do not allow multiple logins by the same user, either through identity authentication using biometrics or owner authentication with IC cards, preventing registered users from simultaneously logging in and delegating operations to unregistered individuals.
Innovation Solution
An authentication apparatus and system that stores user records with both identity and owner authentication information, enabling comparison and permission signals for multiple logins across connected information processing devices, allowing simultaneous login and delegation of operations while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identity authentication using biometrics is performed, then authentication security is improved, but multiple logins by the same user are not allowed
Solution Approach 1:
The authentication system is segmented into two distinct authentication methods: identity authentication (biometrics) and owner authentication (IC card). Each authentication method has its own permission portion that independently manages login permissions. This segmentation allows the system to maintain security through biometric verification while simultaneously enabling multiple logins through IC card delegation, resolving the contradiction between security and multiple login capability.
2Adaptability or versatility
If owner authentication with IC card is performed, then delegation to unregistered persons is enabled, but authentication security is reduced
Solution Approach 1:
The IC card serves as an intermediary that enables delegation of authentication permissions to unregistered persons. When the registered user authenticates via biometrics, they can issue permission signals to others using their IC card. The IC card acts as a mediator that transfers authentication rights without compromising the original biometric security verification, allowing delegation while maintaining the security foundation.
3Ease of operation
If multiple authentication methods are implemented, then user convenience is improved, but system complexity increases
Solution Approach 1:
The authentication apparatus is designed with multi-functionality, incorporating both identity authentication (biometrics) and owner authentication (IC card) within a single system. The storage portion stores both types of authentication information, and the system includes both identity authentication portion and owner authentication portion that work together. This universal design allows users to choose the most convenient authentication method for each situation, improving ease of operation while managing complexity through integrated design.

AI summary
In order to enable multiple logins by a same user, the authentication server includes a registration portion to store a user record including a fingerprint image for authentication of identity of a user and owner authentication information stored in a IC card issued to the user; an identity authentication portion to compare a fingerprint image received from one of MFPs with the one included in the user record for authentication; a first permission portion to transmit a permission signal permitting login based on the authenticated fingerprint image to the MFP that transmitted the fingerprint image; an owner authentication portion to compare owner authentication information received from one of the MFPs with the one included in the user record for authentication; and a second permission portion to transmit a permission signal permitting login based on the authenticated owner authentication information to the MFP that transmitted the owner authentication information.
