Fingerprint Authentication for Secure NFC Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near field communication technologies lack robust authentication methods for personal information, making them vulnerable to unauthorized access, especially when used for transactions like credit card payments, as they do not ensure accurate user authentication.
Innovation Solution
Implementing a fingerprint recognition system that allows access to a security region only if the input fingerprint matches the stored fingerprint, enabling secure transmission of personal information during near field communication by determining the sameness of input and stored fingerprint data and granting access rights to the security region for authorized transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If near field communication is implemented for sharing personal information, then convenience of information transmission is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The system performs fingerprint authentication before allowing near field communication operations. The fingerprint data is captured and verified in advance against stored biometric templates, ensuring that only authenticated users can access personal information for NFC transactions, thus preventing unauthorized access while maintaining convenience
Solution Approach 2:
The patent introduces a biometric authentication module as an intermediary between the user and the near field communication function. This module verifies the user's identity through fingerprint recognition before permitting access to personal information, acting as a security gatekeeper that enables convenient NFC operations while ensuring robust authentication
2Reliability
If fingerprint authentication is added to near field communication, then security is improved, but operation complexity increases
Solution Approach 1:
The patent combines the fingerprint authentication function with the near field communication interface into a unified system. The authentication process is integrated directly into the NFC operation flow, allowing users to perform both authentication and information transmission through a single interaction sequence, thereby reducing perceived operational complexity despite adding security
Solution Approach 2:
The system automatically captures fingerprint data and performs verification without requiring manual intervention beyond the initial finger placement. The authentication process is self-executing, comparing the captured biometric data against stored templates and automatically granting or denying access, which simplifies the user experience while maintaining strong security
