Solution Overview

Problem

Existing portable data carriers face issues with unauthorized data reading due to the need for physical contact and lack of secure biometric verification, allowing unauthorized access and potential theft of sensitive information.

Innovation Solution

A portable data carrier with contactless communication and biometric verification, where the biometric template is stored on the carrier and compared with a sample from an external arrangement, only allowing data transfer and application-specific functions if the sample matches the template, ensuring the rightful owner's consent and knowledge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical contact communication is used between portable data carrier and terminal, then data transfer can be established, but the risk of unauthorized access and corruption increases due to loose contact and corrosion

Engineering Contradiction:
Improvedata transfer reliabilityVSAvoidcontact corrosion and loose contact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical contact-based communication system with a wireless communication system. The portable data carrier and terminal establish data transfer through electromagnetic fields rather than physical contact, eliminating corrosion and loose contact issues while maintaining reliable communication.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If wireless communication is implemented without biometric verification, then communication convenience is improved, but security deteriorates allowing unauthorized data reading

Engineering Contradiction:
Improvecommunication convenienceVSAvoiddata security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements biometric verification before allowing wireless data transfer. The carrier stores biometric templates and performs verification in advance of the actual data communication, ensuring that only authenticated users can access the wireless communication function, thus maintaining both convenience and security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces biometric verification as an intermediary layer between the user and the wireless communication function. This intermediary mechanism authenticates the user's identity before permitting data transfer, preventing unauthorized access while maintaining ease of operation for legitimate users.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If biometric template is stored on the portable data carrier, then verification security is improved, but the complexity of the carrier increases

Engineering Contradiction:
Improveverification securityVSAvoidcarrier complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the biometric verification functionality directly into the portable data carrier by integrating the biometric template storage and verification processes. This combination eliminates the need for separate verification systems, reducing overall system complexity while maintaining high security standards.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A portable data carrier (10) and a method (B1-B10), as well as a storage medium with instructions, for transferring data by means of a portable data carrier are provided. The portable data carrier comprises a carrier storage (12) for storing data containing a biometric template (13) and an application-specific function (15) as well as carrier communication means (11) for contactless receipt and transmission of data. The portable data carrier is characterised in that it further comprises carrier processing means (16) for comparing the biometric template with a biometric sample (23) received from an external arrangement (20), and that it is arranged to complete a handshake process with the external arrangement as well as perform the application-specific function and transmit a result of the same to the external arrangement, only if the biometric sample matches the biometric template.
