Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If identification cards are used for proving identity, then identity verification can be performed, but the user must carry multiple cards which is inconvenient and increases the risk of identity theft

Engineering Contradiction:
Improveconvenience of carrying identificationVSAvoidsecurity against identity theft
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges multiple identification functions into a single mobile device by storing multiple biometric templates (driver's license, credit cards, social security, medical insurance) and their corresponding electronic identifiers in one location, eliminating the need to carry multiple physical cards while maintaining security through biometric authentication

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates digital copies of identification credentials by storing biometric templates and electronic identifiers in a mobile device, allowing users to present these digital copies instead of physical cards, thereby reducing the risk of physical card theft while maintaining verification capability

Inventive Principle:
Principle #26Copying

2Productivity

If identification cards are used for online authentication, then identity verification can be performed, but users need to scan or manually enter information which is time-consuming

Engineering Contradiction:
Improvespeed of identity verificationVSAvoidtime required for authentication
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual card scanning or information entry with automated biometric recognition technology, where the system automatically captures and compares biometric data (fingerprint, facial recognition, etc.) to verify identity instantly, eliminating the mechanical processes of scanning and manual typing

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

Solution Approach 2:

The patent performs preliminary actions by pre-storing biometric templates and electronic identifiers in the mobile device during enrollment, so that during authentication, the system can immediately compare captured biometric data against stored templates without requiring any manual information entry or card scanning

Inventive Principle:
Principle #10Preliminary action

3Reliability

If human evaluation is used to verify identification cards, then identity authentication can be performed, but the evaluation is inconsistent and assumes the evaluator is trustworthy

Engineering Contradiction:
Improveconsistency of identity verificationVSAvoidtrust requirements for evaluators
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces human evaluators with automated biometric recognition systems that objectively compare captured biometric data against stored templates using algorithms, eliminating human subjectivity and inconsistency while reducing trust requirements to the security of the biometric data storage and comparison system

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

Solution Approach 2:

The patent implements feedback mechanisms where the system continuously verifies biometric data against stored templates and provides immediate authentication results, creating a self-validating system that does not rely on human judgment but rather on automated comparison and decision-making algorithms

Inventive Principle:
Principle #23Feedback

4Reliability

If biometric authentication is implemented, then security is improved, but users must trust that their biometric data cannot be stolen and misused

Engineering Contradiction:
Improvesecurity of authenticationVSAvoidrisk of biometric data theft
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments biometric authentication into multiple independent components: biometric template extraction, template storage in secure memory, derivative generation for comparison, and authentication decision-making. This segmentation isolates the sensitive biometric data from direct exposure during transactions, reducing the attack surface for potential theft

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces derivatives as intermediaries between the original biometric template and the authentication process. The derivatives are generated from the templates for comparison purposes but do not reveal the original biometric data, acting as a protective layer that enables authentication while preserving the security and privacy of the original biometric information

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Embodiments of the invention are directed to a method. The method may comprise receiving a second biometric template of a user, and providing an authentication request message comprising an electronic identity and a derivative of the second biometric template of the user to a resource provider computer to conduct an interaction. The authentication request may be forwarded to a processing server computer by the resource provider computer, and the user device may receive an authentication response message comprising an authentication result from the processing server computer. The authentication result may be determined by the processing server computer based on a comparison of the derivative of the second biometric template to a derivative of a first biometric template accessible to the processing server computer. The authentication result may also be based on the validity of the electronic identity.
