Vehicle Data Access Authority Control via Intermediary Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack the ability to control access authority for vehicle data transmitted to user terminals, allowing unauthorized applications to access sensitive information.
Innovation Solution
A vehicle system that includes a storage to set and transmit authority values for accessing vehicle data, allowing only certified or selected applications to access specific data, with a communicator to transmit these values and corresponding data to user terminals, and a certificate server to verify application permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user terminal directly provides vehicle data to applications without access authority control, then the ease of operation is improved, but the security and reliability deteriorate
Solution Approach 1:
The patent introduces an authority value as an intermediary element that mediates between the vehicle data and applications. The authority value is transmitted from the vehicle to the user terminal and used to control which applications can access vehicle data, thereby maintaining security while enabling data access through a structured permission system
Solution Approach 2:
The patent implements preliminary action by pre-defining authority values that specify which applications are permitted to access vehicle data. The vehicle transmits these authority values to the user terminal in advance, establishing access control rules before any data access attempts occur, thus preventing unauthorized access while maintaining ease of operation
2Reliability
If the vehicle transmits authority values and vehicle data to the user terminal, then the reliability of data access control is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by using a general authority value mechanism that can control access to multiple different types of vehicle data through a single unified approach. The authority value system is designed to be multi-functional, handling various applications and data types without requiring separate control mechanisms for each, thus reducing overall system complexity while maintaining reliability
3Reliability
If the user terminal verifies application certificates against authority values, then the reliability of access control is improved, but the loss of time increases
Solution Approach 1:
The patent reduces verification time by performing preliminary action - the vehicle pre-determines and transmits authority values that already specify which applications are permitted to access data. This eliminates the need for time-consuming certificate verification at the user terminal, as the authorization decisions have already been made and communicated in advance, thus maintaining reliability while reducing time loss
Data Source
AI summary
A vehicle includes a storage to store an authority value representing authority to access vehicle data generated by at least one vehicular component and a communicator to transmit the vehicle data and the authority value to a user terminal.
