Wireless Device Location Authentication via Intermediary Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices can falsify their geographic locations, leading to inaccurate location data for service providers and emergency services, which can result in unauthorized services or mislead law enforcement.
Innovation Solution
A method and system for authenticating the geographic location of wireless communication devices by transferring an authentication key, obtaining and authenticating the location, and creating authenticated location information, which is then verified and securely transmitted to ensure the accuracy of the device's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless communication devices determine their own geographic location, then location accuracy can be improved, but the risk of location falsification and tampering increases
Solution Approach 1:
The patent introduces an authentication key as an intermediary mechanism between the wireless communication device and the service node. This authentication key verifies the authenticity of location information without requiring the device to trust its own location determination capabilities, thus resolving the contradiction between location accuracy and location authenticity.
Solution Approach 2:
The system implements a feedback mechanism where the service node receives location information from the wireless communication device, verifies it using the authentication key, and provides authenticated location information back to the service node. This feedback loop ensures that location data is both accurate and authentic before being used for services.
2Reliability
If authentication keys are transferred to service nodes, then location verification reliability is improved, but system complexity increases
Solution Approach 1:
The patent extracts the authentication key management function from the wireless communication device and places it in the service node. This extraction simplifies the device while maintaining verification reliability, as the complex authentication logic is centralized in the service node rather than distributed in each device.
