NFC Mobile Terminal Fingerprint Authentication for Card Emulation Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing NFC mobile terminals face a significant safety hazard due to the potential for unauthorized use in card consumption, as they lack effective user authentication mechanisms, allowing anyone to use a lost or stolen device for transactions.
Innovation Solution
Implementing a fingerprint authentication system that prestores authorized user information, compares inputted fingerprint data with stored data, and only allows card emulation application processing if the fingerprint information matches or exceeds a preset similarity threshold, thereby controlling access to card consumption functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC mobile terminal allows card emulation application without authentication, then ease of operation is improved, but security and reliability deteriorate
Solution Approach 1:
The system performs preliminary fingerprint authentication before allowing card emulation operations. The fingerprint information is collected and verified in advance, ensuring that only authorized users can access the card consumption function, thus preventing unauthorized use while maintaining ease of operation for legitimate users.
2Reliability
If NFC mobile terminal implements fingerprint authentication, then security is improved, but device complexity increases
Solution Approach 1:
The NFC mobile terminal integrates multiple functions including fingerprint sensing, feature extraction, information comparison, and card emulation authentication within a single device. This multi-functional integration allows the system to enhance security through fingerprint authentication without significantly increasing overall device complexity, as these functions are combined in the existing mobile terminal architecture.

AI summary
Disclosed are a method for implementing the card simulation application of a near field communication (NFC) mobile terminal and an NFC mobile terminal. The method includes: prestoring fingerprint information about an authorized user of the NFC mobile terminal; acquiring inputted fingerprint information and comparing the inputted fingerprint information with the prestored fingerprint information about the authorized user of the NFC mobile terminal; if the inputted fingerprint information matches the fingerprint information about the authorized user, then allowing to execute a processing operation of the card emulation application of the NFC mobile terminal; and if the inputted fingerprint information fails to match the fingerprint information about the authorized user, then rejecting to execute a processing operation of the card emulation application of the NFC mobile terminal.
