Distributed Image Storage with User ID Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming systems lack efficient user authentication and data retrieval mechanisms, leading to security concerns and increased costs due to the reliance on centralized print servers and potential information security risks.
Innovation Solution
An image forming system that includes a first storage unit for mapping user identification information to storage locations, an identifying unit for authenticating users, and a retrieval unit for accessing image data, allowing secure and distributed storage and retrieval of image data across multiple image forming apparatuses without a centralized print server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized print server is used to store and manage image data, then data retrieval and management become simplified, but information security risks increase and system costs increase
Solution Approach 1:
The patent segments the centralized storage system into distributed storage units across multiple image forming apparatuses. Each apparatus maintains its own storage unit with mapped user identification information, eliminating the single point of failure and security vulnerability inherent in centralized servers while preserving data accessibility through the mapping mechanism.
2Ease of operation
If a centralized print server is used to store image data, then data management becomes centralized and simple, but system costs increase
Solution Approach 1:
The patent enables self-service distributed storage where each image forming apparatus autonomously manages its own storage unit. The system eliminates the need for expensive centralized server infrastructure by allowing each apparatus to serve its own storage needs while maintaining user identification mappings, thereby reducing overall system costs without sacrificing management capability.
3Reliability
If distributed storage without centralized server is used, then information security is improved and costs are reduced, but data retrieval efficiency may be compromised
Solution Approach 1:
The patent introduces an intermediary mapping mechanism where user identification information is mapped to specific storage locations across distributed apparatuses. This intermediary layer enables efficient data retrieval by providing a direct lookup path from user ID to storage location, eliminating the need for complex distributed queries while maintaining security and decentralization.

AI summary
An image forming system includes a first storage unit that stores identification information and storage information with the identification information mapped to the storage information, the identification information identifying a user, the storage information indicating a storage location where image data corresponding to the identification information is stored, an identifying unit that, in response to the identification information input by the user, identifies the storage location indicated by the storage information stored on the first storage unit with the identification information mapped thereto, a retrieval unit that retrieves, from the storage location identified by the identifying unit, the image data corresponding to the identification information, and an image forming unit that forms an image responsive to the image data retrieved by the retrieval unit.
