Solution Overview

Problem

Current security systems lack clear visibility into the location and movement of individuals within facilities, making it difficult to enforce access control policies and respond to emergencies, as they rely on manual processes and do not effectively utilize electromagnetic (EM) or radio frequency (RF) signatures for authentication and presence tracking.

Innovation Solution

A system utilizing EM sensor networks to detect and analyze RF fingerprints from mobile devices, generating electronic personas that combine with access control data to provide real-time location tracking and behavior analysis, enabling enhanced security and compliance monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual processes are used for access control and presence tracking, then system complexity is reduced, but security monitoring effectiveness and real-time visibility deteriorate

Engineering Contradiction:
Improvesecurity monitoring effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical processes with electromagnetic field-based detection systems. RF sensors and EM sensors automatically detect and track electronic devices, substituting human-operated manual systems with automated electromagnetic detection infrastructure that provides continuous real-time monitoring without manual intervention

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

Solution Approach 2:

The system creates digital copies of physical presence through electronic personas. Each detected device generates an electronic persona that replicates the physical individual's location and movement data, allowing security personnel to monitor and track individuals remotely through their device-generated digital twins rather than direct physical observation

Inventive Principle:
Principle #26Copying

2Loss of information

If electromagnetic sensors and RF fingerprinting are deployed throughout facilities, then real-time location tracking and behavior analysis improve, but infrastructure complexity and implementation cost worsen

Engineering Contradiction:
Improvevisibility into location and movementVSAvoidinfrastructure complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system uses universal electronic devices that individuals already carry (smartphones, tablets, laptops) as tracking identifiers. These multi-functional devices serve both their primary communication purposes and as unique identifiers for security tracking, eliminating the need for dedicated tracking hardware and reducing infrastructure complexity

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

Solution Approach 2:

The patent introduces electronic personas as intermediary entities between physical individuals and the security system. These digital intermediaries aggregate device data and translate it into actionable security information, simplifying the connection between complex sensor networks and security personnel by providing a unified interface for monitoring

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If electronic personas combine access control data with RF fingerprints, then authentication accuracy and policy enforcement improve, but data processing complexity increases

Engineering Contradiction:
Improveauthentication accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system merges multiple authentication factors into a unified electronic persona model. Access control data, RF fingerprints, location information, and behavioral patterns are combined into a single integrated profile, enabling comprehensive authentication and policy enforcement through one consolidated data structure rather than separate systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary data aggregation and persona creation in advance of security decisions. Electronic personas are continuously updated with device and location data before authentication events occur, so that when access control decisions are needed, pre-processed persona data is already available, reducing real-time processing complexity

Inventive Principle:
Principle #10Preliminary action

AI summary

Electromagnetic (EM)/radio frequency (RF) emissions may be detected and corresponding EM personas may be created. One or more EM personas may be associated with a super persona corresponding to a particular entity. EM personas, super personas, and/or supplemental identifying information can be used to enforce security protocols.
