Connected Car Service Data Backup via Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected car service information, including usage history and personal data, is vulnerable to exposure when the vehicle is lent or taken for repairs, lacking effective protection mechanisms.
Innovation Solution
A method that involves generating backup data of connected car service information and transferring it securely between a connected car terminal, a mobile terminal, and a telematics server using short-range wireless communication or mobile communication, ensuring data protection by removing the information from local memory after backup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connected car service information is stored locally in the terminal, then service functionality is maintained, but data privacy is compromised when the vehicle is lent or taken for repairs
Solution Approach 1:
The system performs preliminary backup of service information to a remote server before the vehicle is lent or taken for repairs. This advance action ensures that data is already secured externally when the vulnerability window occurs, preventing exposure without affecting local service functionality.
Solution Approach 2:
A remote server acts as an intermediary between the connected car terminal and the stored service information. Instead of direct local storage that exposes data, the server mediates data storage and retrieval, allowing service functionality to be maintained while preventing direct access to sensitive information during vulnerable periods.
2Object-affected harmful factors
If service information is deleted from local memory to protect privacy, then data exposure is prevented, but service continuity is disrupted
Solution Approach 1:
The system creates a copy of service information and stores it on a remote server while maintaining the original locally. This copying approach allows the local terminal to delete or clear sensitive data to prevent exposure, while the remote copy ensures service continuity by enabling data restoration when needed.
Solution Approach 2:
The system performs preliminary backup to a remote server before local data deletion occurs. This advance copying ensures that when local memory is cleared for protection, the service information remains accessible through the remote server, maintaining service continuity without compromising privacy.
3Reliability
If backup data is stored on a remote server, then data security is improved, but communication requirements and system complexity increase
Solution Approach 1:
The remote server provides multiple functions including data backup, secure storage, and data restoration capabilities within a single system component. This multi-functionality improves data security without proportionally increasing system complexity, as one universal server handles multiple protective operations.
Solution Approach 2:
The connected car terminal automatically performs backup operations to the remote server without requiring complex user configuration or intervention. The system self-manages the communication and data transfer processes, reducing the operational complexity despite the added security infrastructure.

AI summary
A connected car service information protection method is used for backing up connected car service information stored in a connected car terminal onto a mobile terminal of a user in response to a request of the user. The method further enables restoring of the backup data stored in the user's mobile terminal to the connected car terminal. The connected car service information protection method includes establishing a communication connection with the mobile terminal by the connected car terminal, generating backup data for the connected car service information by the connected car terminal, and transmitting the backup data to the mobile terminal by the connected car terminal.
