Smart Key Vehicle Data Access for Secure Erasure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems face challenges in managing large amounts of data generated by various modules, leading to complexity in data management, security risks, and issues with data erasure during vehicle sale or scrapping.
Innovation Solution
A vehicle data access system utilizing a smart key module to authenticate and control access to vehicle data stored in a central storage module, enabling secure management and erasure of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data are distributed and stored in various modules within the vehicle, then each module can manage data independently, but data management complexity increases and security risks arise
Solution Approach 1:
The patent consolidates data storage into a centralized storage module that handles all vehicle data from various modules (sensor modules, infotainment modules, navigation modules, communication modules). This merging approach reduces data management complexity while maintaining the ability of individual modules to generate and access their data independently through standardized interfaces.
2Ease of operation
If data erase operation and security management are not performed properly, then data access is convenient, but user's personal information or sensitive vehicle data may be leaked
Solution Approach 1:
The patent introduces a controller as an intermediary between the smart key and the storage module. This controller manages authentication operations, controlling when and how data can be accessed or erased. The controller mediates between the user's convenience needs and security requirements by implementing proper authentication protocols before allowing data access or erasure operations.
Solution Approach 2:
The patent implements preliminary authentication operations through the smart key before allowing data access or erasure. This preliminary action ensures that only authorized users can access or erase data, preventing security breaches while maintaining convenient access for legitimate users.
3Loss of information
If vehicle data are not erased during vehicle sale or scrapping, then data can be retained for historical reference, but previous data may remain without deleting the vehicle data creating security risks
Solution Approach 1:
The patent enables the vehicle's own controller to automatically perform data erasure operations when a smart key authentication is detected, indicating a sale or scrapping event. This self-service mechanism ensures that data is properly erased without requiring manual intervention, eliminating security risks while maintaining data retention during normal vehicle operation.
4Reliability
If a smart key authentication system is implemented to control data access, then data security is enhanced, but system complexity increases
Solution Approach 1:
The patent implements a universal smart key authentication system that handles multiple functions (data access control, data erasure authorization, vehicle operation control) through a single authentication mechanism. This multi-functional approach enhances data security while minimizing system complexity by using one authentication system for multiple purposes rather than separate systems for each function.
