Database Segregation for Equipment Management Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment management systems do not adequately protect user information from unauthorized access, posing a risk to user privacy.
Innovation Solution
The system segregates user information into a separate database that is inaccessible from the control apparatus managing equipment information, allowing access to equipment data while prohibiting access to user data, thereby enhancing security measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If user information is stored in the same database as equipment information accessible by control apparatus, then data management is simplified, but user information security is compromised
Solution Approach 1:
The patent divides the database into two separate databases: a first database for equipment information and a second database for user information. The controller is configured to allow access to the first database from the control apparatus while prohibiting access to the second database from the control apparatus. This segmentation isolates sensitive user information from the control apparatus, preventing unauthorized access while maintaining manageable database structures through separate, purpose-specific databases.
2Loss of information
If control apparatus has access to all information including user information, then comprehensive data availability is achieved, but information security is reduced
Solution Approach 1:
The patent implements different access rights for different types of information. The controller allows the control apparatus to access equipment information in the first database while prohibiting access to user information in the second database. This local quality approach assigns specific access permissions based on the nature and sensitivity of each data type, ensuring that the control apparatus receives only the information necessary for its function while sensitive user information remains protected.
Data Source
AI summary
An equipment management system comprises a first database configured to store equipment information about an equipment, a second database configured to store user information about a user, and a controller configured to collect the equipment information from a control apparatus controlling the equipment. The controller is configured to allow access to the first database from the control apparatus. The controller is configured to prohibit access to the second database from the control apparatus.
