Vehicle UX Data Isolation Against HTML5 Script Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infotainment systems in vehicles are vulnerable to data leakage through script injection, compromising the security of vehicle data managed and output using HTML5-based interfaces.
Innovation Solution
A vehicle information provision system that processes vehicle data and interface data using different system languages, specifically a vehicle programming language and a markup language, to synthesize and output the data in a user experience environment, enhancing security by preventing data leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle data is managed and output through an HTML5-based interface, then the user experience and information display capability are improved, but the security of vehicle data deteriorates due to vulnerability to script injection
Solution Approach 1:
The system segments the data processing into two distinct paths: vehicle data is processed through a vehicle programming language module while interface data is processed through a markup language module. This segmentation prevents vehicle data from being exposed to potential script injection vulnerabilities in the HTML5 interface, thereby maintaining both user experience and data security.
Solution Approach 2:
The processor acts as an intermediary that receives vehicle data from the vehicle data reception module, processes it through the vehicle programming language module, and then integrates it with interface data processed through the markup language module. This intermediary processing ensures vehicle data never directly enters the HTML5 interface environment where script injection could occur.
2Device complexity
If vehicle data and interface data are processed through the same markup language environment, then the system complexity is reduced, but the security against script injection attacks deteriorates
Solution Approach 1:
The system divides data processing into separate modules: a vehicle programming language processing module for vehicle data and a markup language processing module for interface data. This segmentation increases system complexity but is necessary to prevent script injection attacks by isolating vehicle data from the HTML5 environment.
3Productivity
If vehicle data is directly integrated into the UX environment, then the data integration efficiency is improved, but the risk of data leakage increases
Solution Approach 1:
The processor serves as an intermediary that integrates vehicle data into the UX environment through controlled processing. Vehicle data is processed through the vehicle programming language module, then passed through the markup language module where it is safely converted to interface data format before being integrated into the HTML5 UX environment. This intermediary process maintains integration efficiency while preventing data leakage by never exposing raw vehicle data to the HTML5 environment.

AI summary
A vehicle information provision system, an information provision method thereof, and a vehicle including the same are proposed. The proposed are implemented to strengthen security for vehicle data by synthesizing and outputting data obtained by processing vehicle interface data and the vehicle data based on different system languages. The vehicle information provision system may include a first data reception module for receiving vehicle data, a second data reception module for receiving vehicle interface data and first metadata related to the vehicle data, and a processor for processing the vehicle data and the vehicle interface data based on system languages different from each other and synthesizing the vehicle data based on the first metadata into a user experience (UX) environment generated by processing the vehicle interface data.
