Solution Overview

Problem

Current identity management systems face challenges in authenticating individuals while maintaining privacy, as they rely on identifiable information that can be compromised, risking security and privacy of personal data.

Innovation Solution

An anonymous association system utilizing biometrics, where biometric markers create a matrix of associations among ancillary data elements without identifying the individual, using a biometric input device to retrieve keys for institution and user identifiers, allowing secure data aggregation and access without revealing the user's identity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional identity management systems use identifiable information for authentication, then authentication reliability is improved, but privacy security deteriorates

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidprivacy security
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes personally identifiable information (PII) from the authentication system. Instead of storing or transmitting actual identity data, the system uses only biometric templates and randomized keys, separating the authentication function from identity revelation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces randomized keys as intermediaries between biometric data and account information. These keys act as mediators that enable authentication without directly linking biometric data to personal identity, thus protecting privacy while maintaining authentication reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If biometric data is stored centrally for authentication, then authentication speed is improved, but security risk increases

Engineering Contradiction:
Improveauthentication speedVSAvoidsecurity risk
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent segments the authentication system into distributed components. Biometric templates are stored locally on user devices rather than centrally, and authentication decisions are made through distributed verification across multiple systems, reducing the security risks associated with centralization while maintaining speed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary enrollment actions where biometric templates are converted into randomized keys during initial setup. This preliminary transformation ensures that even if data is intercepted during authentication, the actual biometric information remains protected, reducing security risks without affecting authentication speed.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If multiple data sources are aggregated using traditional methods, then data completeness is improved, but privacy protection deteriorates

Engineering Contradiction:
Improvedata completenessVSAvoidprivacy protection
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent creates a universal randomized key system that can aggregate data from multiple sources without requiring source-specific identifiers. The same key structure works across different data sources, enabling complete data aggregation while maintaining consistent privacy protection through the use of randomized keys instead of personal identifiers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An anonymous database system includes a plurality of biometric nodes in communication with one another. Each of the plurality of biometric nodes includes a biometric input that receives biometric data from a user. The system also includes at least one central database in communication with the plurality of biometric nodes; and a plurality of institution databases in communication with the plurality of biometric nodes. A first node of the plurality of biometric nodes is configured to receive a message from a second node of the plurality of biometric nodes, the message requesting authorization of data access by the second node. Various embodiments relate to a method for performing an action requiring multiple levels of authentication using an anonymous database system.
