Innovation Solution

A system utilizing mobile devices and cellular communications for secure two-person access authorization, which includes establishing a secure data connection, real-time person-to-person communication, and biometric verification, leveraging geolocation and mobile app functionalities to facilitate authorization decisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional two-person access rule systems are used, then security verification is provided, but remote and mobile authorization is not supported

Engineering Contradiction:

Improveremote and mobile authorization capabilityVSAvoidsecurity verification strength

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a mobile device as an intermediary between the authorized user and the resource. The mobile device captures biometric data (photos, voice samples) and geolocation information, then transmits this data to the authorization system. This intermediary enables remote authorization while maintaining security by collecting physical-world attributes through the mobile device's sensors and cameras.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical presence verification (physical co-location of authorized users) with electronic and optical fields. Biometric data captured by mobile devices (visual attributes via camera, voice via microphone) substitutes for physical presence, enabling remote verification while maintaining security through analysis of these field-based attributes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If physical presence verification is required, then security is enhanced, but ease of operation for remote access is reduced

Engineering Contradiction:

Improveremote access convenienceVSAvoidphysical verification requirement

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent substitutes mechanical physical presence requirements with field-based verification methods. The mobile device captures visual attributes (photos), acoustic attributes (voice samples), and geolocation data, replacing the need for physical co-location. The authorization system analyzes these field-based attributes to verify identity, enabling remote access while maintaining verification reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the verification parameters from physical presence (spatial parameter) to biometric and geolocation parameters. Instead of requiring the authorized user to be physically present at a specific location, the system verifies visual attributes, voice characteristics, and GPS coordinates captured by the mobile device, enabling remote verification through parameter transformation.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If modern mobile technologies are integrated, then adaptability for mobile authorization is improved, but system complexity increases

Engineering Contradiction:

Improvemobile technology integrationVSAvoidsystem architecture complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent leverages the mobile device's existing multi-functional capabilities (camera, microphone, GPS, processor) to perform multiple verification functions. The same device that captures photos for visual verification also records voice samples and tracks geolocation. This universal mobile platform reduces overall system complexity by consolidating multiple verification functions into a single device rather than requiring separate systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system using mobile devices and a network provides access authentication, authorization and accounting to computing resources using a two-person access rule solution approach. A central access control server coordinates a rule-based authorization process in which a requesting user and one or more authorizing users are engaged in real-time communications to facilitate approved access to a sensitive resource. The technique utilizes mobile cellular interfaces and location service technologies, while also providing traditional security control measures of voice and visual verification of user identities.
