IC Card Fingerprint Recognition Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC cards relying on personal identification codes for verification are vulnerable to theft and require users to remember multiple codes, leading to inconvenience and security risks.
Innovation Solution
Integration of fingerprint recognition functionality into IC cards, allowing verification of user identity through fingerprint information, thereby eliminating the need for personal identification code input during transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal identification code verification is used, then the IC card transaction system is simple to operate, but the security is poor and codes are easily stolen
Solution Approach 1:
The patent replaces the mechanical input method (typing PIN code) with a biometric recognition system (fingerprint scanning). The fingerprint recognition module captures and verifies fingerprint patterns, substituting the manual code entry process with an automated biometric verification process, thereby improving security while maintaining ease of operation.
Solution Approach 2:
The patent changes the verification parameter from a user-defined code (PIN) to a unique physiological parameter (fingerprint). This parameter change ensures that each user has a distinct, hard-to-replicate identifier, significantly enhancing transaction security while requiring minimal user effort beyond placing a finger on the scanner.
2Adaptability or versatility
If multiple IC cards are used, then the functionality is versatile, but the user may forget or confuse the personal identification codes
Solution Approach 1:
The patent creates a biometric copy of the user's fingerprint and stores it in the IC card's secure memory. This fingerprint template serves as a unique identifier that travels with the card, eliminating the need for users to remember separate codes for different cards. The system copies and stores the essential verification data (fingerprint pattern) directly in the card.
3Reliability
If fingerprint recognition is added to IC card, then the security is improved, but the device complexity increases
Solution Approach 1:
The patent merges the fingerprint recognition module with the existing IC card structure, integrating the biometric verification system into the card's hardware and software architecture. The fingerprint sensor, processing unit, and storage are combined within the card, creating a unified device that performs both traditional and biometric verification functions without requiring separate standalone systems.

AI summary
A working method for an IC card having a fingerprint recognition function, comprising: an IC card receiving and determining an instruction type from a terminal, and when determined that the received instruction is an application selection instruction, the IC card selecting an application and returning a response to the terminal; when determined that the received instruction is a processing option acquisition instruction, the IC card acquiring a user fingerprint information verification state according to the content of the instruction, and if verification is successful, returning to the terminal a processing option instruction response containing an application file locator list for which a personal identification number does not need to be verified; if verification fails, returning to the terminal a processing option instruction response containing an application file locator list for which a personal identification number must be verified; when determined that the received instruction is a record reading instruction, the IC card returning a record reading response to the terminal according to the record reading instruction, wherein the record reading response contains a method for verifying a card holder. Thus, the risk of a personal identification number being leaked is avoided, thus enhancing the security of a transaction, while also improving user experience.
