Solution Overview

Problem

Current authentication systems are cumbersome and prone to fraud, as they often require multiple inputs and do not provide strong authentication, making them inefficient and susceptible to unauthorized use.

Innovation Solution

A method and system that uses biometric identification information to authenticate users by prompting clients for biometric data, comparing it with stored sample data from a database, and only completing transactions if the match exceeds a predetermined threshold, thereby providing strong and efficient authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multifactor authentication is used, then security is improved, but authentication time and complexity increase

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-enrolling users with multiple authentication factors (biometric data, security questions, passwords) stored in a database. During authentication, these pre-prepared factors are rapidly presented and evaluated, eliminating the need for sequential verification of multiple factors and reducing authentication time while maintaining security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the authentication process by evaluating multiple factors simultaneously rather than sequentially. The authentication flow adapts based on the user's responses and biometric verification results, allowing the system to complete verification faster when confidence is high while maintaining security requirements.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If traditional authentication methods are used, then ease of operation is maintained, but authentication strength decreases

Engineering Contradiction:
Improveauthentication convenienceVSAvoidauthentication strength
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system replaces traditional mechanical authentication methods (typing passwords, answering security questions) with biometric authentication (fingerprint, facial recognition, iris scanning). This substitution maintains ease of operation as biometric verification is naturally intuitive, while dramatically improving authentication strength by using unique physiological characteristics that are difficult to replicate or steal.

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

Solution Approach 2:

The system changes the fundamental parameter of authentication from knowledge-based (passwords, security questions) to biology-based (fingerprint patterns, facial geometry, iris structure). This parameter change maintains user convenience while providing significantly stronger authentication that is resistant to fraud and unauthorized access.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If biometric authentication is implemented, then authentication strength is improved, but system complexity increases

Engineering Contradiction:
Improveauthentication strengthVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system introduces a centralized authentication server as an intermediary that manages the complexity of biometric verification. This server handles biometric data storage, comparison operations, and authentication logic, allowing client devices to perform simple biometric capture and forward results for verification. This distribution of complexity maintains strong authentication while simplifying the user-facing interface and client device requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for authenticating a user identity for a data transaction is provided. The method is implemented using an identity authentication computing device in connection with a memory and a data transaction processor. The method includes receiving a request from a first user of a first client device for a data transaction with a second user, causing a second client device to prompt the second user for biometric identification information, receiving captured biometric identification information corresponding to the second user, retrieving sample biometric identification information associated with the second user, comparing the captured biometric information and the sample biometric information, determining that the captured and the sample biometric information match, completing a data transaction between the first user and the second user, and transmitting an instruction to one or more of the first client device and the second client device displaying a notification that the data transaction is completed.
