Solution Overview

Problem

Existing wireless security models prioritize ease of access and mobility over privacy and security, leaving users' mobile devices vulnerable to location disclosure and network spoofing.

Innovation Solution

Implementing an intelligent access control agent on wireless devices that uses passive receivers to collect network information and determine location, allowing users to control network access and prevent unauthorized localization through a database of cleared networks and geospatial parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless networks are designed for ease of access and mobility, then network accessibility and user convenience are improved, but privacy and security are compromised

Engineering Contradiction:

Improveease of accessVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the wireless network access process into multiple phases: initial network scanning, authentication, and data transmission. During the scanning and authentication phases, the device uses passive receiving mode to avoid disclosure of its location, while allowing legitimate network access. This segmentation allows the system to maintain security during vulnerable phases while preserving ease of access during authorized phases.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary authentication and location verification before establishing full network access. The device performs passive scanning to identify networks, then verifies network legitimacy and determines its own location before allowing data transmission. This preliminary action prevents unauthorized access and location disclosure while maintaining convenient access for authorized networks.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If passive scanning is used to collect network information, then network identification capability is improved, but energy consumption increases

Engineering Contradiction:

Improvenetwork identification capabilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic passive scanning instead of continuous scanning. The device scans for networks at specific intervals and remains in a low-power state between scans. This periodic approach maintains the ability to identify and connect to networks while significantly reducing energy consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

3Reliability

If active transmission is used for network communication, then communication reliability is improved, but location disclosure risk increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidlocation disclosure risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the location-disclosing transmission function from the communication function. During authentication and setup phases, the device uses passive receiving only, avoiding any transmission that would reveal its location. Once authorized connection is established, controlled transmission occurs for actual data communication. This extraction separates the harmful location-disclosing aspect from the necessary communication aspect.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An emission control scheme intended to limit the localization and identification of a wireless device to known friendly wireless networks. Use of an intelligent access control (IAC) on a wireless device allows the user or administrator control over the revealing of the wireless device to any particular network. Passive scanning allows collection of network information while passive device-based location and on-board databased information on the wireless networks allows localization to thwart network spoofing for unfriendly positioning and identification of the wireless device.
