Device Management System for Network Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network devices, such as printers or multifunction peripherals, face challenges in reconnecting to a cloud system for data restoration after hard disk failures or authentication information loss, leading to difficulties in performing backup and restore operations without burdensome client efforts.
Innovation Solution
A device management system that provides a first screen to issue key information for network devices to reconnect, managing authentication information and allowing reconnection to a client tenant, using device registration and reconnection keys to facilitate seamless data restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is stored on the hard disk of the network device, then the network device can connect to the cloud system, but the network device cannot reconnect after hard disk failure or authentication information loss
Solution Approach 1:
The system pre-registers the network device with the cloud system before authentication information is lost. When reconnection is needed, the cloud system uses the pre-stored device identification information to generate new authentication information and send it to the network device, eliminating the need for complex client-side re-registration operations.
Solution Approach 2:
The cloud system acts as an intermediary between the network device and the authentication mechanism. Instead of storing authentication information locally on the hard disk, the cloud system manages and distributes authentication information to the network device based on pre-registered device identification, enabling seamless reconnection after failures.
2Speed
If the network device reconnects automatically after failure, then reconnection speed improves, but security may be compromised without proper authentication verification
Solution Approach 1:
The network device is pre-registered with the cloud system before actual use, storing device identification information in advance. When reconnection is needed, the cloud system quickly verifies this pre-stored information and generates new authentication credentials, enabling both fast reconnection and secure verification without requiring manual client intervention.
Data Source
AI summary
A device management system issues key information for a client tenant that is identified according to input of identification information of a network device via a screen, and, when a key type of the key information received from the network device is reconnection and the network device that is a source from which the key information is sent is a network device that has been managed with the client tenant associated with the key information, send, to the network device, authentication information to reconnect the network device to the device management system.
