IC Card Biometric Registration via Remote Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC card systems require users to visit facilities for biometric authentication data registration, which is inconvenient and lacks secure network transmission of biometric information.
Innovation Solution
An IC card system and method that includes an IC card management server, MNO server, and terminal device, where the IC card management server requests user verification and generates a registration application with a card ID and secret key, allowing secure biometric authentication information registration on the IC card without direct network transmission of biometric data, using a fingerprint sensor and secure communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication data is registered at physical facilities such as bank counters, then security is maintained through controlled environments, but user convenience deteriorates due to the need to visit specific locations
Solution Approach 1:
The patent introduces a communication terminal as an intermediary device that enables remote biometric data registration. The terminal captures biometric information locally and transmits it securely to the IC card system without requiring physical presence at a facility, thus improving convenience while maintaining security through the mediated communication channel
Solution Approach 2:
The patent replaces the mechanical/physical system of visiting facilities with electronic/digital communication systems. Biometric data is captured via sensors in the terminal and transmitted electronically, substituting the physical journey and in-person registration process with remote digital communication, thereby improving ease of operation
2Ease of operation
If biometric information is transmitted over the network for registration, then registration convenience is improved, but security deteriorates due to potential data interception
Solution Approach 1:
The patent extracts and transmits only the essential authentication data needed for IC card registration rather than transmitting complete biometric information. The system captures biometric data locally, extracts relevant authentication features, and transmits only this processed information over the network, reducing the risk of harmful factors while maintaining registration convenience
Solution Approach 2:
The patent transforms biometric information from its original form into processed authentication data with different parameters. The raw biometric data is converted into extracted features or authentication codes that retain verification capability but minimize information exposure, thereby reducing interception risk while enabling remote registration
3Measurement precision
If complete biometric information is stored and transmitted, then authentication accuracy is improved, but security and privacy protection deteriorate
Solution Approach 1:
The patent creates and uses a simplified copy or representation of biometric information rather than the complete original data. The system generates authentication data that replicates the verification function of complete biometric information but contains less sensitive information, thereby maintaining authentication accuracy while reducing privacy exposure
Solution Approach 2:
The patent extracts only the necessary authentication features from complete biometric information. By taking out and transmitting only the essential verification data rather than the full biometric dataset, the system maintains measurement precision for authentication while minimizing the exposure of sensitive personal information
Data Source
AI summary
An IC card system includes an IC card management server and an IC card. The IC card management server requests a SIM management server to make an inquiry regarding a user based on card identification information and user information relating to a contract of SIM card, and, in a case that validity of the user is verified, transmits a generation request for generating a registration application registering biometric authentication information, including the card identification information and the secret key, to the SIM management server. The IC card includes a data storage storing the card identification information and the secret key and storing the biometric authentication information and, in a case that authentication based on the card identification information and the secret key through communication with the SIM card based on the registration application is succeed, stores the biometric authentication information based on the biometric information in the data storage.
