Vehicle Telematics Data Access Control Using Local Allow Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data connectivity management systems in vehicles often lead to reduced profit due to lost subscriptions, as they lack efficient access management and billing optimization, resulting in unnecessary data access and communication costs.
Innovation Solution
A computer-implemented method and system that processes resource identifier requests by retrieving and analyzing an electronically stored allow list associated with a vehicle's wireless data plan, determining accessibility, and assigning router ports to allow or disallow application access, thereby managing data access efficiently and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a third party billing service verifies data access requests centrally, then data access control is achieved, but system complexity and communication overhead increase
Solution Approach 1:
The patent extracts the billing verification function from the central third party billing service and places it locally in the vehicle's telematics control unit. The TCU now independently verifies data access requests against stored billing information and allow lists, eliminating the need for centralized verification and reducing system complexity while maintaining reliable access control.
Solution Approach 2:
The patent implements preliminary action by pre-storing billing information, allow lists, and access control parameters in the TCU before data access requests occur. This allows the system to perform local verification without real-time communication with external billing services, reducing communication overhead and system complexity while ensuring reliable access control.
2Reliability
If all data access requests are verified through external billing services, then centralized billing management is achieved, but communication costs and data transmission increase
Solution Approach 1:
The patent extracts the billing verification function from external billing services and implements it locally in the TCU. The TCU now independently verifies data access requests against stored billing information, allow lists, and subscription data, eliminating the need for continuous external communication and reducing communication costs while maintaining reliable billing management.
Solution Approach 2:
The patent implements self-service by enabling the TCU to autonomously verify data access requests using locally stored billing information and allow lists. The system serves itself by performing billing verification without external intervention, reducing communication costs and data transmission while ensuring reliable billing management through local decision-making.
3Reliability
If router ports are dynamically assigned based on allow lists, then data access security is improved, but processing time and computational load increase
Solution Approach 1:
The patent implements preliminary action by pre-generating and storing allow lists containing authorized application identifiers and router port mappings in the TCU before data access requests occur. When a data access request is received, the TCU performs a simple lookup in the pre-computed allow list rather than performing complex real-time verification, maintaining high data access security while minimizing processing time and computational load.
Data Source
AI summary
A system and method for processing a resource identifier request in a vehicle that includes receiving an application data access request from at least one of an in-vehicle device and a portable device. The system and method also include retrieving and analyzing an electronically stored allow list that is stored and updated based on a wireless data plan that is associated with the vehicle and determining accessibility of the application based on analysis of the allow list. The system and method further include assigning a router port of at least one router of a telematics communication unit of the vehicle to allow or disallow accessibility of the application based on determined accessibility of the application.
