Cloud Backup Encryption for Image Forming Apparatus Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring data from an old electronic device to a new one require external storage or PCs and involve file format conversions, which can be inconvenient and inefficient.
Innovation Solution
A cloud-based system that generates and transmits encrypted backup data, using a security key for authentication and file format conversion as needed, allowing seamless data transfer and restoration between image forming apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is backed up using external storage devices or PCs, then data transfer between electronic devices is achieved, but device complexity and operation inconvenience increase
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the first and second image forming apparatuses. The cloud receives backup data from the first apparatus and transmits it to the second apparatus, eliminating the need for direct external storage devices or PCs. This mediator approach simplifies the data transfer process while maintaining security through encryption.
Solution Approach 2:
The patent replaces the mechanical/physical data transfer system (external storage devices, USB cables, PC interfaces) with a network-based cloud system. Data is transmitted through network communication protocols rather than physical connections, reducing device complexity and improving operational convenience.
2Reliability
If all data is backed up and transmitted, then complete data restoration is achieved, but transmission time and data volume increase
Solution Approach 1:
The patent segments the data transfer process into distinct phases: backup phase (first apparatus to cloud), authentication phase (security key verification), and restoration phase (cloud to second apparatus). This segmentation allows for more efficient processing and reduces overall transfer time while maintaining completeness through systematic data handling.
Solution Approach 2:
The cloud server performs preliminary actions by receiving and storing backup data before the restoration process begins. The system prepares the data in advance and only transmits it when authentication is complete, reducing the time required for actual restoration operations.
3Adaptability or versatility
If file format conversion is performed manually, then data compatibility is achieved, but operation complexity and time consumption increase
Solution Approach 1:
The cloud server automatically handles file format conversion as part of its service. When the second apparatus requests data restoration, the cloud identifies format compatibility issues and performs conversions automatically without requiring manual intervention from the user, thus maintaining adaptability while simplifying operation.
Data Source
AI summary
An apparatus and method for backing up data by using a cloud are provided. According to an example, the method may include receiving a data backup request from a first image forming apparatus, receiving a backup data list generated by using a first security key, the first security key generated to encrypt data and identification information of the first image forming apparatus, receiving, from the first image forming apparatus, backup data encrypted by using the first security key, receiving, from a second image forming apparatus, a second security key corresponding to a data restoration request, and, when the second security key received from the second image forming apparatus is the same as the first security key generated to encrypt the data, transmitting the backup data list to the second image forming apparatus.
