Virtual Device Maintenance Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In maintenance work systems, workers permitted to work on multiple virtual devices risk accidentally performing maintenance on non-target devices, leading to potential errors or unintended actions.
Innovation Solution
A non-transitory computer readable medium and information processing system that accepts maintenance instructions for specific target devices, allowing workers to perform maintenance only on the corresponding virtual device and prohibiting work on non-target devices by using a worker database to manage permissions and instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a worker is permitted to work on multiple virtual devices, then the worker can perform maintenance on more devices, but the worker may accidentally work on non-target devices
Solution Approach 1:
The system segments the worker's access rights by creating distinct permission sets for different virtual devices. Each virtual device has its own permission information that specifies which workers can access it and under what conditions. This segmentation prevents workers from accidentally accessing devices they are not authorized for, while still allowing them to work on multiple devices when properly permitted.
Solution Approach 2:
The permission information management apparatus acts as an intermediary between workers and virtual devices. It manages and controls access by reading permission information from memory and determining whether workers can access specific virtual devices. This intermediary layer ensures that workers can only access devices for which they have explicit permission, preventing accidental work on non-target devices.
2Reliability
If permission information is stored in memory for each device, then access control is improved, but system complexity increases
Solution Approach 1:
The permission information management apparatus performs multiple functions: it stores permission information, reads permission information, determines access rights, and manages worker-device permissions. By consolidating these functions into a single apparatus, the system achieves reliable access control without proportionally increasing complexity. The same apparatus handles all permission-related operations for all virtual devices.

AI summary
A non-transitory computer readable medium stores a program causing a computer to execute a process for information processing, the process including: accepting a maintenance instruction for performing maintenance work on a target device which is one of plural physical devices; and permitting a worker who is able to work on plural virtual devices provided one-to-one with the plural physical devices to perform, as the maintenance work, only work on a virtual device corresponding to the target device, and prohibiting the worker from working on a virtual device corresponding to a non-target device other than the target device among the plural physical devices.
