Motor Vehicle User Data Deletion via Local Profile Assistant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deleting user data from motor vehicles, particularly in rental scenarios, are inefficient as they require manual intervention and lack centralized control for resetting device settings, compromising user privacy and operational efficiency.
Innovation Solution
A method and device that utilize a local profile assistant module (LPA) to receive a delete command from a server computer, triggering a clearing routine via a data management module to reset user-specific device settings to standard values, ensuring user data is removed without additional communication pathways, thereby centralizing the deletion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user data is deleted manually in the vehicle, then user privacy is protected, but operational efficiency decreases and manual intervention is required
Solution Approach 1:
The system enables self-service deletion by allowing the server computer to automatically delete user data from the vehicle without requiring manual intervention inside the vehicle. The server sends a deletion command that is executed autonomously by the vehicle's control units, eliminating the need for users or operators to manually clear data.
Solution Approach 2:
The server computer acts as an intermediary between the user and the vehicle's data management system. By routing deletion commands through the server, the system enables remote data management without requiring direct interaction with the vehicle's internal systems, thus improving operational efficiency while maintaining security.
2Ease of operation
If deletion is controlled from outside the vehicle, then ease of operation improves, but device complexity increases
Solution Approach 1:
The server computer performs multiple functions including data management, authentication, and deletion control. By consolidating these functions in a single external system, the patent avoids adding complex distributed control mechanisms within the vehicle while still enabling remote operation.
Solution Approach 2:
The deletion control functionality is extracted from the vehicle's internal systems and placed in an external server. This separation reduces the complexity of the vehicle's data management architecture while maintaining the capability for remote operation.
3Loss of information
If all user data including device settings is deleted, then user privacy is enhanced, but loss of information increases
Solution Approach 1:
The system applies different deletion behaviors to different types of data based on their sensitivity. User profile data and personal information are completely deleted, while device settings may be preserved or reset based on specific conditions and user preferences, allowing nuanced data management.
Solution Approach 2:
Instead of deleting all data uniformly, the system performs partial deletion by selectively removing only the necessary user-specific information while potentially retaining non-sensitive device settings. This approach balances privacy protection with information retention.

AI summary
The disclosure relates to a method for deleting user data in a motor vehicle. The method includes storing user data in an eUICC chip of a communication controller that enables user access to a mobile radio network, the user profile data including setting data of a device setting performed during use of the motor vehicle by at least one user in at least one other controller different from the communication controller, and receiving a delete command for removal of the user profile data in the communication controller by a profile assistant module of the communication controller from a server computer, the profile assistant module being coupled to a data management module of the motor vehicle, executing the delete command, wherein the user access to the mobile radio network is prevented by executing the delete command, and sending a clearing command by the profile assistant module to the data management module.
