Biometric Smart Card Data Recording via Transaction Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face constraints when configuring biometric smart cards, such as bank cards or access badges, as they need to visit institutions or use specific devices to record personal biometric data, which is inconvenient and not secure.
Innovation Solution
A method that allows users to configure biometric smart cards by recording reference biometric data during conventional transactions protected by a personal secret code using external devices like payment terminals or smartphones, without requiring separate visits or devices, while maintaining security through secure data recording and validation mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users configure biometric smart cards by visiting institutions or using specific devices, then security of biometric data recording is improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The system enables users to autonomously record their biometric data during routine transactions without requiring visits to institutions or use of special devices. The smart card automatically captures biometric data (e.g., fingerprint) during standard payment operations, allowing users to configure their own biometric identification securely through normal card usage.
Solution Approach 2:
The patent combines the biometric data recording function with routine transaction processing. The same payment terminal and transaction flow used for regular payments are also utilized to capture and store biometric data, merging two functions into a single integrated process that occurs during normal card operations.
2Reliability
If users configure biometric smart cards through separate visits or devices, then security of the configuration process is improved, but time consumption and productivity deteriorate
Solution Approach 1:
The system performs biometric data recording during routine transactions before the user needs the biometric functionality. By capturing biometric data during regular payment operations, the configuration is completed in advance, so when the user later wants to use biometric authentication, it is already available without requiring additional setup time.
Solution Approach 2:
The useful action of transaction processing continues uninterrupted while biometric data is being recorded. The system maintains normal payment flow and simultaneously captures biometric information, ensuring that the configuration process does not interrupt or delay the user's primary transaction activities.
3Ease of operation
If biometric data is recorded during conventional transactions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The payment terminal and smart card system are designed to perform multiple functions: routine transaction processing and biometric data recording. The same hardware components and communication protocols used for payments are leveraged to also capture and store biometric information, avoiding the need for separate dedicated biometric configuration devices.
Solution Approach 2:
The smart card acts as an intermediary that bridges the payment terminal and biometric data storage. The card contains a biometric sensor and secure storage elements that interface with the existing payment terminal infrastructure, allowing biometric functionality to be added without fundamentally changing the terminal's core payment processing architecture.

AI summary
The invention relates to a method of recording a reference biometric data in a biometric smart card comprising a biometric sensor characterized in that the recording (24) of a biometric data acquired by the biometric sensor, as reference biometric data, is carried out in response to the validation (22), by the biometric smart card, of a personal secret code of the user of the biometric smart card entered on a first external device to authorise a transaction between the biometric smart card and a second external device via the first external device.
