In-Vehicle Terminal Link with Security Verification Before Screen Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is ensuring safety in the connection between in-vehicle devices and information terminals, particularly in verifying the security status of the information terminal to prevent software viruses from invading the in-vehicle device during data transmission.
Innovation Solution
An in-vehicle device with a communication interface, verification interface, display, and operation interface that verifies the security status of the information terminal before displaying its screen, ensuring that only secure data is transmitted and processed, and providing user notifications for connection and operation restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the in-vehicle device directly displays information from the information terminal, then the user convenience is improved, but the security risk increases due to potential software viruses
Solution Approach 1:
The patent applies preliminary action by performing security verification of the information terminal before allowing direct display of information. The verification interface checks security status in advance, and only after confirmation does the system enable direct display functionality, thus preventing potential virus invasion while maintaining user convenience
2Reliability
If security verification is performed before connection, then the security status is improved, but the connection time increases
Solution Approach 1:
The patent applies self-service by enabling the information terminal to automatically perform security verification and provide security status information without requiring manual user intervention. This automated process reduces the time overhead of security checks while ensuring reliable security verification before connection
3Adaptability or versatility
If the in-vehicle device controls the display from the information terminal, then the device functionality is improved, but the safety risk increases during vehicle operation
Solution Approach 1:
The patent applies preliminary anti-action by implementing safety notifications and warnings before allowing control operations during vehicle operation. The system detects the operational state and preemptively alerts the user about safety risks, preventing harmful actions before they occur while still maintaining device functionality
Data Source
AI summary
A communication interface can connect to an information terminal. When detecting the connection between the communication interface and the information terminal, a verification interface verifies the security status of the information terminal. When there is no problem in the security status of the information terminal verified by the verification interface, a display displays an image based on an image signal received by the communication interface from the information terminal. The operation interface accepts an operation on the image displayed by the display. The communication interface transmits an operation signal responsive to the operation accepted by the operation interface to the information terminal, and then receives an image signal as a result of processing by the information terminal in accordance with the operation signal from the information terminal.
