In-Vehicle Device Content Delivery Security via Company Code Cross-Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle content delivery systems lack adequate security measures, allowing unrestricted access to user information, which poses a risk in the delivery of personal data related to content preferences and advertisements.
Innovation Solution
An in-vehicle device equipped with communication, storage, and control means that determines the authenticity of delivery companies, writes uplink information only for qualified companies, and deletes it when access ceases or upon request, ensuring secure content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the in-vehicle device allows unrestricted access to storage area for content delivery, then the ease of operation and content delivery efficiency is improved, but the security of user information is worsened
Solution Approach 1:
The patent segments the storage area into multiple regions with different access permissions. The control means divides the storage area so that only specific regions can be accessed by delivery companies, while other regions remain protected. This segmentation allows content delivery to proceed smoothly in authorized areas while maintaining security in protected areas, thus resolving the contradiction between ease of operation and security.
2Adaptability or versatility
If multiple delivery companies can access the storage area, then the adaptability and content variety is improved, but the security control becomes more complex
Solution Approach 1:
The patent implements preliminary action by pre-configuring access permissions for multiple delivery companies before actual content delivery occurs. The control means is designed in advance to recognize and differentiate between various delivery companies, with predetermined access rules for each. This preliminary setup enables multiple companies to access the storage area simultaneously with appropriate permissions without requiring complex real-time authorization decisions, thus maintaining adaptability while controlling complexity.
3Reliability
If the in-vehicle device stores uplink information continuously, then the reliability of data availability is improved, but the loss of time for data deletion and security risk increases
Solution Approach 1:
The patent applies periodic action by implementing time-based access and deletion mechanisms. The control means is configured to automatically delete uplink information after predetermined time periods or after specific conditions are met. This periodic deletion ensures that data remains available for the necessary duration to maintain reliability, while simultaneously limiting the time data remains stored, thereby reducing security risks and complying with data retention policies.
Data Source
AI summary
When notification information about a company code is received from a center device, a control unit of an in-vehicle device refers to uplink information which is generated for each qualified delivery company and stored in a storage unit and cross-checks the company code included in the uplink information with the received company code (step S8). Only when those are identical, the uplink information corresponding to the company code to which it is judged that those are identical is read out from the storage unit and written in an uplink information storage area of the storage unit of a DSRC unit (step S9). Security on content information delivery is improved.
