Image Forming Apparatus Backup Management by Setup Environment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device management systems for image forming apparatuses do not adequately consider setup environments when managing backup data, leading to the potential application of unsuitable settings during restoration, which can expose the devices to security threats.
Innovation Solution
A device management system that includes a network device with a selecting unit to choose the setup environment, a setting unit to set appropriate setting values for the selected environment, and a backup unit to transmit this information to a device management service, which stores it as backup data, ensuring that backup data is managed based on the current setup environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup data is stored without considering setup environment, then storage and management is simple, but unsuitable settings may be applied during restoration exposing the device to security threats
Solution Approach 1:
The patent segments backup data by setup environment types (intranet environment, internet environment, and unspecified environment). Each environment has its own designated setting items that are stored and restored separately. This segmentation ensures that only environment-appropriate settings are restored, preventing security vulnerabilities while maintaining organized backup management.
Solution Approach 2:
The patent performs preliminary classification of setting items according to setup environment types before backup operations. The system pre-defines which setting items correspond to which environment types, and this classification is applied during backup creation. This preliminary action ensures that when restoration occurs, only compatible settings are applied, eliminating security risks without requiring complex real-time analysis.
2Productivity
If all setting information is restored based on backup data, then restoration is complete, but the device state may be rewound more than necessary
Solution Approach 1:
The patent extracts and restores only the necessary setting items based on the current setup environment rather than restoring all setting information. The system identifies which setting items are relevant to the current environment type and restores only those, leaving other settings unchanged. This extraction approach ensures complete restoration of environment-critical settings while preserving current appropriate settings, avoiding unnecessary rewinds.
3Reliability
If security settings are customized for different environments, then security is improved, but the complexity of managing different setting configurations increases
Solution Approach 1:
The patent creates a universal backup data structure that accommodates multiple setup environment types through a unified management framework. The system uses environment type identifiers and designated setting item lists that work across all environment types (intranet, internet, unspecified). This universal approach allows the system to handle diverse security requirements without requiring separate management systems for each environment, reducing overall complexity while maintaining environment-specific security settings.
Data Source
AI summary
In a case where a backup management unit of an image forming apparatus detects a change in a setup environment of the image forming apparatus, the backup management unit transmits information of changed setting values and information of the setup environment to a backup management server. A data management unit of the backup management server associates the setting information received from the image forming apparatus with the setup environment information, and stores and manages the information in a backup database as backup data of the image forming apparatus.
