Location Validation System Using Multi-Source Trusted Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to validate the location reported by wireless communication devices to prevent users from falsifying their location information, which is essential for law enforcement, vendors, and system operators to ensure accurate location-based services and compliance with regulations, especially in emergency situations and commercial transactions.
Innovation Solution
A location validation system comprising a communication interface to receive the asserted location and a processing system to determine a trusted location by comparing it with information from other sources, generating a notification if the asserted location differs from the trusted location, using methods such as GPS signals, WAN signal analysis, and application usage data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users report location information from wireless communication devices, then location-based services can be provided, but the location information may be falsified and unreliable
Solution Approach 1:
The patent introduces a location validation server as an intermediary between the wireless communication device and the location-based service provider. This server receives asserted location information from the device, independently determines trusted location information using multiple sources (GPS, cell tower triangulation, Wi-Fi positioning), compares the two, and validates the location before it is used for service delivery. This intermediary layer ensures reliability without requiring complex validation logic in each service application.
Solution Approach 2:
The system implements feedback by continuously monitoring and comparing asserted location information against trusted location information from multiple independent sources. The validation server provides feedback on whether the location is valid or falsified, enabling real-time detection of location spoofing attempts and allowing the system to reject or flag unreliable location data before it affects service delivery.
2Measurement precision
If multiple location determination methods are used to verify location, then location accuracy is improved, but system complexity and processing time increase
Solution Approach 1:
The validation server employs partial action by selectively applying different validation methods based on the situation. It uses GPS data when available and reliable, supplements with cell tower triangulation when GPS is unavailable or suspicious, and uses Wi-Fi positioning as additional verification. This layered approach achieves high accuracy without always invoking all possible validation methods, thus reducing processing time while maintaining precision.
Solution Approach 2:
The system performs preliminary action by pre-establishing trusted location information from multiple sources before validation is needed. The validation server continuously monitors and stores location data from GPS, cell towers, and Wi-Fi networks, so when location validation is required, the comparison can be performed quickly against pre-computed trusted data rather than gathering all location information at the moment of validation.

AI summary
A location validation system comprising a communication interface configured to receive an asserted location of a wireless communication device and a processing system configured to determine a trusted location of the wireless communication device, receive the asserted location from the communication interface, compare the asserted location to the trusted location, and generate a notification if the asserted location differs from the trusted location.
