Solution Overview

Problem

Existing biometric identification systems face challenges in efficiently managing and trusting biometric identifiers across multiple credential granting authorities, leading to redundant authentication processes and security concerns when users access resources from different organizations.

Innovation Solution

A server system that receives, stores, and manages biometric identifiers associated with users from various credential granting authorities, accesses trust data to determine if one authority trusts identifiers collected by another, allowing for seamless inheritance and use of biometric identifiers across trusted authorities, thereby streamlining user authentication and access to resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric identifiers are collected and stored by multiple credential granting authorities independently, then security and identification accuracy are improved, but system complexity and authentication redundancy increase

Engineering Contradiction:

ImprovesecurityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges biometric identifier management across multiple credential granting authorities by implementing a centralized trust data storage mechanism. The server system consolidates trust relationships between different authorities, allowing biometric identifiers collected by one authority to be recognized and trusted by others, thereby reducing system complexity while maintaining security through unified management.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universal trust data structures that enable a single biometric identifier to serve multiple credential granting authorities. The trust data model allows biometric identifiers to be universally recognized across different organizations and systems, eliminating the need for separate authentication processes for each authority while maintaining security through standardized trust verification.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If each credential granting authority requires its own biometric authentication, then identification accuracy is improved, but authentication time and user convenience deteriorate

Engineering Contradiction:

Improveidentification accuracyVSAvoidauthentication time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-establishing trust relationships between credential granting authorities in advance. Trust data is stored and validated beforehand, allowing the system to quickly determine whether a biometric identifier from one authority is trusted by another without requiring real-time verification, thereby reducing authentication time while maintaining identification accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by allowing biometric identifiers collected by one credential granting authority to be copied and used by other trusted authorities. Instead of requiring separate biometric collections, the system copies the trusted identifier across multiple authorities, eliminating redundant authentication processes while preserving identification accuracy through the established trust relationships.

Inventive Principle:

Principle #26Copying

3Ease of operation

If biometric identifiers are shared across multiple authorities, then user convenience and authentication efficiency are improved, but security risks and trust verification complexity increase

Engineering Contradiction:

Improveuser convenienceVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces an intermediary mechanism through centralized trust data management on the server system. This intermediary layer verifies and manages the trust relationships between credential granting authorities, allowing biometric identifiers to be safely shared across multiple authorities while maintaining security through standardized verification processes. The trust data acts as a mediator that ensures secure interoperability without compromising security.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A biometric identifier is received, from a first credential granting authority, is associated with a user and was collected by the first credential granting authority. The biometric identifier is stored in association with the user and the first credential granting authority. Trust data is accessed and enables determination of whether a second credential granting authority trusts biometric identifiers collected by the first credential granting authority. It is determined that the second credential granting authority trusts biometric identifiers collected by the first credential granting authority based on the accessed trust data. Based on the determination that the second credential granting authority trusts biometric identifiers collected by the first credential granting authority, biometric identification of the user using the biometric identifier collected by the first credential granting authority is performed for the second credential granting authority.
