Person-Specific Data Access Control for Agricultural Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural machinery data handling systems lack efficient access control and data distribution mechanisms, leading to difficulties in managing malfunctions and ensuring that only authorized personnel access sensitive data.
Innovation Solution
A method and data system that enable person-specific access to agricultural machine data through a user interface, allowing automatic determination of access levels based on user categories, and facilitating informed decision-making and data access in the event of malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data access is enabled for multiple personnel categories, then operational efficiency is improved through timely access to relevant data, but data security deteriorates due to increased risk of unauthorized access
Solution Approach 1:
The patent implements person-specific access rights that grant different levels of data access to different personnel categories. Each category (driver, service employee, manufacturer representative) receives tailored access permissions matching their specific operational needs, allowing efficient access to relevant data while restricting access to sensitive data for those who don't need it.
2Ease of operation
If comprehensive data access is provided to all personnel, then problem-solving capability is improved through access to all relevant information, but complexity of access management deteriorates
Solution Approach 1:
The system automatically determines and assigns appropriate access rights based on the person's category and the specific situation (normal operation vs. malfunction). The data system autonomously manages access control without requiring manual configuration for each user, reducing administrative complexity while ensuring comprehensive data access for problem-solving when needed.
Solution Approach 2:
Access rights are dynamically adjusted based on the operational context. During malfunctions, the system can temporarily expand access rights to allow service employees and manufacturer representatives to access diagnostic data needed for problem-solving, while returning to restricted access during normal operation.
3Reliability
If data access is restricted to specific personnel categories, then data security is improved through controlled access, but operational efficiency deteriorates due to delays in accessing necessary data
Solution Approach 1:
Access rights for different personnel categories are pre-configured and stored in the data system before any data access is requested. When a user attempts to access data, the system immediately checks the pre-defined access rights for that user's category, enabling instant grant or denial of access without manual approval delays, thus maintaining both security and efficiency.
4Reliability
If person-specific access determination is implemented, then data protection is improved through appropriate access control, but system complexity increases due to automated determination requirements
Solution Approach 1:
The data system autonomously determines appropriate access rights based on stored criteria linking personnel categories to data types and access levels. The system self-manages the complexity of access control logic without requiring external intervention, implementing data protection through automated, context-aware decisions rather than simple static rules.
Data Source
AI summary
A method for handling data relating to an agricultural machine. The method includes enabling an access to the data relating to an operation of the agricultural machine via at least one user interface, and automatically determining on a person-specific basis which access is enabled for a specific person via a data system.
