Biometric IC Card Activation Collation for Faster Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IC cards requiring biometric authentication, such as those using fingerprint data, suffer from lengthy processing times during the collation process.
Innovation Solution
An IC card equipped with a fingerprint sensor, a collation processor, and a storage unit that performs biometric authentication at the time of activation, allowing for early collation of user biometric information with pre-stored data, thereby reducing the processing time required for personal authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is performed using conventional IC cards, then personal security is improved, but processing time is excessive
Solution Approach 1:
The patent applies preliminary action by performing biometric template extraction and storage in the IC card memory before the actual authentication process. When a user presents their biometric data, the card already has the template ready for immediate comparison, eliminating the need to extract and process the template during the authentication moment, thus significantly reducing processing time while maintaining security

AI summary
An integrated circuit (IC) card of an embodiment includes a communicator, a storage storing biometric authentication information, an acquirer, and a processor. The communicator communicates with a terminal device. The acquirer acquires biometric information of a user. The processor collates the biometric information of the user acquired by the acquirer with the biometric authentication information stored in the storage and stores a collation result into the storage at an activation time.
