Vehicle Location Services via Backend Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Global Navigation Satellite System (GNSS) devices are vulnerable to malicious attacks, such as man-in-the-middle attacks, which can lead to inaccurate position and heading calculations, posing safety risks to users.
Innovation Solution
A method that involves a vehicle detecting a malicious attack and communicating with a backend system to acquire accurate location data from a wireless carrier system, providing this data to the vehicle until the attack is mitigated, and then ceasing to do so once the threat is no longer present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle uses GNSS data for location determination, then location services are provided, but the system becomes vulnerable to malicious attacks and position accuracy deteriorates
Solution Approach 1:
The patent introduces a backend system as an intermediary between the vehicle and the location service provider. The backend system receives location data requests from the vehicle, detects malicious attacks, and coordinates with the location service provider to deliver accurate location information, thereby protecting the vehicle from spoofing attacks while maintaining reliable location services
Solution Approach 2:
The patent implements preliminary detection of malicious attacks by the backend system before location data is provided to the vehicle. The system proactively identifies spoofing attempts and prepares countermeasures in advance, preventing inaccurate location data from reaching the vehicle
2Measurement precision
If the vehicle requests location data from the backend system during an attack, then accurate position information is obtained, but system complexity and communication overhead increase
Solution Approach 1:
The backend system serves as an intermediary that centralizes the complexity of attack detection and mitigation. Instead of making the vehicle complex, the backend handles the sophisticated detection algorithms and coordination with location service providers, keeping the vehicle system relatively simple while achieving high position accuracy
Solution Approach 2:
The patent implements a feedback mechanism where the vehicle sends attack detection notifications to the backend system, which then provides corrected location data. This feedback loop enables accurate position information to be delivered without requiring the vehicle to implement complex detection algorithms itself
Data Source
AI summary
A vehicle communication system and method of improving location services for a user in a vehicle are described. The method includes the steps of: receiving at a backend system a first message from the vehicle based on a determination of a malicious attack associated with global navigation satellite system (GNSS) data received by the vehicle; receiving from a wireless carrier system (WCS) location data associated with a position of the vehicle; providing the location data to the vehicle from the backend system in response to the receipt of the first message; receiving a second message from the vehicle indicating that the malicious attack is no longer viable; and in response to receiving the second message, ceasing to provide the location data from the backend system.
