Solution Overview

Problem

Existing methods for recording biometric data on cards, such as payment cards, are inconvenient and require multiple stages or additional confidential codes, making them cumbersome and insecure.

Innovation Solution

A method involving a microcontroller in the card communicating via a secure channel with a remote server through a device application, authenticating the user and server, and recording biometric data using a fingerprint reader after mutual authentication, eliminating the need for additional codes and in-person visits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the card holder goes to the card issuer to record biometric data, then the biometric data can be recorded securely, but the process becomes inconvenient and time-consuming

Engineering Contradiction:

Improvesecurity of biometric data recordingVSAvoidconvenience of recording process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The card holder can perform biometric data recording independently at home using their mobile device and the card's fingerprint reader, without requiring visits to card issuer offices. The system enables self-service recording while maintaining security through authentication protocols.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A mobile application serves as an intermediary between the card holder and the card issuer's authentication system. The application facilitates secure communication and authentication, enabling remote biometric recording without direct contact with the card issuer's physical offices.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If biometric data recording is performed remotely without in-person verification, then convenience is improved, but security and authentication reliability deteriorate

Engineering Contradiction:

Improveconvenience of remote recordingVSAvoidauthentication reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary authentication of the card holder through the mobile application before enabling biometric data recording. This preliminary verification ensures that only authorized users can initiate the recording process, maintaining security while enabling remote operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authentication system provides feedback mechanisms to verify the card holder's identity and authorize the recording process. The system continuously monitors and verifies authentication status throughout the recording process, ensuring reliability while maintaining convenience.

Inventive Principle:

Principle #23Feedback

3Reliability

If additional confidential codes are used for authentication, then security is improved, but the complexity of the system and ease of operation deteriorate

Engineering Contradiction:

Improvesecurity of authenticationVSAvoidcomplexity of authentication system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mobile application serves multiple functions including authentication, biometric data acquisition, and communication with the card issuer. By consolidating these functions into a single application, the system reduces overall complexity while maintaining strong security through multi-factor authentication.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the authentication process with the biometric recording process into a single integrated flow. The mobile application combines authentication verification and biometric data capture in one seamless operation, eliminating the need for separate confidential codes and reducing system complexity.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If biometric data recording is done in two stages with separate verification, then security is improved, but the time required and convenience for the card holder deteriorate

Engineering Contradiction:

Improvesecurity of biometric verificationVSAvoidtime required for recording process

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system merges authentication verification and biometric data recording into a single simultaneous process. The mobile application and card work together in one integrated operation, eliminating the need for separate verification stages and reducing the overall time required while maintaining security.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The authentication and biometric recording processes continue simultaneously without interruption. The system maintains continuous verification and recording in a single uninterrupted flow, eliminating idle time between stages and improving both speed and convenience.

Inventive Principle:

Principle #20Continuity of useful action
