Biometric Credential Authentication for Real-Time Identity Validation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional authentication systems fail to verify the identity of the individual presenting a credential document, allowing sophisticated individuals to falsify their identities using valid but illegally obtained documents, and similar issues arise in online transactions where fraudulent credentials are presented.

Innovation Solution

A system that biometrically authenticates a user by simultaneously capturing a biometric sample and an image of a user credential, comparing the biometric sample to stored data to confirm the user's identity and validating the credential data against a database, ensuring the user is the authentic owner of the credential.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional document validation systems are used to verify credential validity, then credential authenticity is improved, but identity verification capability deteriorates

Engineering Contradiction:

Improvecredential authenticityVSAvoididentity verification

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The system merges credential validation with biometric authentication into a unified process. The processor simultaneously verifies the credential document's validity and compares biometric data from the credential against live biometric samples, combining two separate verification functions into one integrated system that addresses both credential authenticity and identity verification.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Biometric data embedded in the credential document serves as an intermediary element that bridges credential validation and identity verification. The system extracts biometric data from the credential as an intermediate step, then uses this extracted biometric information to authenticate the presenter's identity, creating a logical bridge between verifying the document and verifying the person.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If biometric comparison is performed against stored data, then authentication accuracy is improved, but processing time increases

Engineering Contradiction:

Improveauthentication accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

Biometric data is extracted and stored in the credential document during the credential issuance process, before the authentication event occurs. This preliminary preparation of biometric information eliminates the need for complex real-time biometric extraction during authentication, reducing processing time while maintaining accuracy through direct comparison with pre-prepared reference data.

Inventive Principle:

Principle #10Preliminary action

AI summary

A system for authenticating a user includes a memory device, and a processor. The processor is configured to receive a first biometric sample associated with a user from a biometric measurement device, and receive, substantially contemporaneously with receiving the first biometric sample, an image of a user credential, where the image includes credential data, such as any of a variety of personally identifiable information. The processor may also be configured to compare the received first biometric sample to at least one of: i) a second biometric sample included in the credential data, or ii) a third biometric sample stored by an authentication database in association with the user. Likewise, in at least some embodiments, the processor may determine whether to authenticate the user, such as based upon the comparison.
