Vehicle Wireless Network Authentication Using Velocity Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network security systems in vehicles face challenges in efficiently securing network access, particularly in scenarios where traditional security keys are difficult to distribute, often resulting in unsecured access points due to passenger mobility in vehicles like taxis or buses.
Innovation Solution
The system uses velocity information from both the vehicle and mobile devices to determine whether the mobile device is within the vehicle, allowing secure network access without the need for a security key by comparing the velocity data to grant or deny access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security keys are used for wireless network access in vehicles, then network security is improved, but ease of operation deteriorates due to difficulties in distributing security keys to passengers in vehicles like taxis or buses
Solution Approach 1:
The patent replaces the mechanical key distribution system with a velocity-based authentication system using GPS data and mobile device sensors. Instead of distributing physical or digital security keys through traditional channels, the system uses velocity information from the mobile device's motion sensors and GPS to authenticate users based on their movement patterns matching the vehicle's movement, eliminating the need for key distribution infrastructure
Solution Approach 2:
The patent changes the authentication parameter from static security keys to dynamic velocity data. The system collects velocity information from mobile devices using accelerometers, gyroscopes, and GPS, then compares these dynamic parameters against expected velocity patterns for authorized users in the vehicle, allowing authentication without traditional keys
2Ease of operation
If velocity-based authentication is implemented, then ease of operation is improved by eliminating security key distribution, but device complexity increases due to requirements for GPS and motion sensors
Solution Approach 1:
The patent leverages the multi-functionality of modern mobile devices that already contain GPS receivers, accelerometers, gyroscopes, and other motion sensors for purposes like navigation and fitness tracking. By repurposing these existing components for authentication, the system avoids adding dedicated hardware while still achieving velocity-based security
Solution Approach 2:
The mobile device itself performs the authentication function by using its own built-in sensors to collect velocity data and communicate it to the access point. The device serves its dual purpose of both navigation/motion tracking and security authentication, eliminating the need for separate authentication hardware or infrastructure
3Reliability
If location-based velocity data is collected for authentication, then network security is improved by verifying device proximity to vehicle, but loss of information increases due to collection and processing of sensitive location data
Solution Approach 1:
The patent extracts only the essential velocity information needed for authentication from the mobile device's comprehensive sensor data. Instead of collecting or storing detailed location history, personal information, or comprehensive movement patterns, the system isolates and processes only the velocity vectors required to determine whether the device is moving with the vehicle, minimizing data collection to the minimum necessary for security
Data Source
AI summary
Methods, systems, and computer program products for vehicle wireless internet security are provided. A connection request is received from a mobile device. A data request is transmitted to the mobile device. The data request includes a request for location-based data of the mobile device. A first data is received from the mobile device that corresponds to the data request. A vehicle data is generated that comprises location-based data of the vehicle. A match between the first data and the vehicle data is determined. A match is determined where the location based data of the mobile device is with a pre-determined threshold of the location-based data of the vehicle.
