Vehicle API Access Control with Consent and Trust Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to adequately control access to vehicle APIs from external devices, risking leakage of personal information and unauthorized vehicle control.
Innovation Solution
An access control device and method that includes an access controller, acceptance determination unit, and start confirmation unit to manage access privileges to vehicle APIs, ensuring user consent and reliability verification before granting access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control is implemented to prevent unauthorized access and information leakage, then security is improved, but system complexity increases due to multiple verification units and privilege management
Solution Approach 1:
The access control system is divided into distinct functional units: acceptance determination unit, start confirmation unit, and service provision unit. Each unit handles a specific aspect of access control, allowing the system to manage security complexities through modular organization while maintaining robust security protocols
Solution Approach 2:
The acceptance determination unit performs preliminary verification of service provider reliability before granting access privileges. This advance verification ensures that only trusted external devices can access vehicle APIs, preventing unauthorized access and information leakage before they can occur
2Adaptability or versatility
If access privileges are granted to external applications for service provision, then service functionality is improved, but risk of unauthorized vehicle control increases
Solution Approach 1:
Access privileges are dynamically granted and revoked based on service execution status. The service provision unit monitors whether services are executed normally and adjusts access privileges accordingly, allowing external applications to control vehicle functions only when necessary and under supervision
Solution Approach 2:
The system implements feedback mechanisms where the service provision unit continuously monitors service execution and reports status to the acceptance determination unit. This feedback loop enables real-time adjustment of access privileges, ensuring that external applications cannot perform unauthorized vehicle control even if they initially have access
3Reliability
If multiple verification steps are implemented to ensure user consent and provider reliability, then access security is improved, but service response time increases
Solution Approach 1:
User consent and service provider reliability are verified in advance before service execution begins. The acceptance determination unit completes all necessary verification steps prior to granting access privileges, so that once services start running, no additional verification delays occur
Solution Approach 2:
The system dynamically adjusts verification intensity based on the established trust relationship. After initial verification confirms provider reliability and user consent, subsequent service operations proceed with minimal verification overhead, maintaining both security and responsiveness

AI summary
An access control device or an access control method receives an access request from an application programming interface (API) use application provided outside a vehicle, controls access to a vehicle API, and assigns, to the API use application, an access privilege to a vehicle API that provides a function of a start confirmation unit, assigns an access privilege to the vehicle API necessary for providing a target service to the API use application.
