Fingerprint Smart Card Enrollment Through POS Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fingerprint smart cards face inefficiencies in enrollment processes, requiring users to visit banks and lack robust security measures, leading to increased costs and inconvenience.
Innovation Solution
A fingerprint enrollment method for smart cards that allows enrollment through a POS terminal using a two-step authentication process: first with a user authentication means and then with a PIN code, enabling secure storage of fingerprint information without bank visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fingerprint enrollment is performed through traditional bank channels, then security is maintained, but user convenience deteriorates and distribution costs increase
Solution Approach 1:
The patent introduces a POS terminal as an intermediary device between the user and the fingerprint enrollment system. The POS terminal acts as a trusted mediator that can perform authentication and facilitate secure fingerprint enrollment without requiring users to visit banks, thereby improving convenience while maintaining security through the terminal's authentication capabilities
Solution Approach 2:
The system enables users to perform fingerprint enrollment independently through POS terminals without requiring bank staff assistance. Users can complete the enrollment process themselves by interacting with the POS terminal interface, which guides them through authentication and fingerprint capture, thus improving ease of operation while maintaining security through automated verification
2Reliability
If two-step authentication is implemented for fingerprint enrollment, then security is improved, but process complexity increases
Solution Approach 1:
The authentication process is segmented into two distinct steps: first authentication using existing credentials (PIN, password, or biometric) and second authentication specifically for fingerprint enrollment. This segmentation allows each authentication step to be optimized independently, maintaining high security while making the complex process more manageable and understandable for users
Solution Approach 2:
The first authentication step serves as a preliminary verification before allowing fingerprint enrollment. By performing this initial authentication in advance, the system ensures that only authorized users can proceed with fingerprint enrollment, thereby maintaining security while structuring the complex process into manageable sequential steps
3Productivity
If fingerprint enrollment is restricted to bank visits, then security control is maintained, but distribution efficiency deteriorates
Solution Approach 1:
The POS terminal is utilized for multiple functions including its traditional payment processing role and the additional function of fingerprint enrollment. By making the POS terminal universal and multi-functional, the system can perform fingerprint enrollment at any location with a POS terminal, dramatically improving distribution efficiency while maintaining security through the terminal's existing authentication and communication capabilities with the server

AI summary
In a fingerprint enrollment method of a fingerprint smart card configured to communicate with a server and to enroll fingerprint information through a point of sale (POS) terminal, the method includes determining whether the fingerprint information is enrolled in the fingerprint smart card, performing a first authentication based on a user authenticator corresponding to the fingerprint smart card, in response to determining the fingerprint information is not enrolled in the fingerprint smart card, receiving the fingerprint information, in response to the first authentication being successfully completed, performing a second authentication based on the server and a personal identification number (PIN) code corresponding to the fingerprint smart card, storing the fingerprint information in the fingerprint smart card, in response to the second authentication being successfully completed, and omitting the first authentication and the second authentication in response to determining the fingerprint information is enrolled in the fingerprint smart card.
