Solution Overview

Problem

Existing security systems require users to enroll with personally identifiable information, compromising privacy and flexibility, and lack efficient biometric authentication methods for immediate access.

Innovation Solution

An AdHoc enrollment process that captures biometric data without requiring formal enrollment, using facial scans and session tags to verify identity, and employs algorithms to match and store templates securely, ensuring privacy and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional enrollment process is used, then system security is improved, but user privacy is compromised due to collection of personally identifiable information

Engineering Contradiction:
Improvesystem securityVSAvoiduser privacy
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts and removes personally identifiable information (PII) from the enrollment process, retaining only biometric data and session tags. This extraction principle resolves the contradiction by eliminating PII collection while preserving security functionality through biometric verification alone.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces session tags as an intermediary mechanism that links biometric data to user sessions without requiring PII. This intermediary allows the system to maintain security and user identification capabilities while avoiding direct collection of sensitive personal information.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If formal enrollment with PII is required, then user identification accuracy is improved, but system flexibility is reduced

Engineering Contradiction:
Improveuser identification accuracyVSAvoidsystem flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system performs automatic biometric verification without requiring users to manually provide PII. The self-service principle enables the system to autonomously capture and verify biometric data, maintaining identification accuracy while eliminating the rigidity of formal enrollment procedures.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements a dynamic enrollment process where biometric verification can occur in multiple modes (formal and AdHoc). This dynamic approach allows the system to adapt between structured enrollment when needed and flexible walk-through verification when appropriate, maintaining both accuracy and versatility.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If biometric data is collected without formal enrollment, then user privacy is protected, but verification reliability may be compromised

Engineering Contradiction:
Improveuser privacyVSAvoidverification reliability
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The system performs preliminary biometric capture and template generation during the AdHoc enrollment process before actual verification is needed. This preliminary action ensures that biometric templates are properly established and stored with session tags, enabling reliable verification later without requiring formal enrollment at the time of use.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the system continuously verifies biometric data against stored templates and session tags. This feedback loop ensures verification reliability by confirming that AdHoc-enrolled users are properly authenticated while maintaining privacy through automated validation without PII.

Inventive Principle:
Principle #23Feedback

AI summary

Methods and systems are provided for an AdHoc enrollment process. A user may be able to enroll and be verified by a system for a variety of actions or authentications without being forced to turn over personally identifiable information and without having to formally enroll. The system may compare captured biometric information with existing biometric information and may identify the user without the use of personally identifiable information.
