Information Processing Device Historical Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network systems for information processing devices, such as those described in Japanese Patent Provisional Publication No. 2004-102549A, restrict data reuse to only the user who initially requested the print operation, limiting convenience and data accessibility for authorized users within the same department and raising concerns about data protection.
Innovation Solution
An information processing device connected to a client device via a network, equipped with an image processing unit, historical information acquisition, transmission, request reception, and data obtaining units, allowing users to acquire and reuse historical data related to image reading and print operations by selecting and retrieving specific job data from a client device, while maintaining data security by limiting access to authorized users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server stores historical data and allows only the original user to access it, then data security is maintained, but data accessibility and usability for other authorized users deteriorates
Solution Approach 1:
The patent segments the historical data by associating it with specific information processing devices (copying devices) rather than storing all data centrally in the server. Each copying device maintains its own historical data locally, allowing users to access data from their own device without compromising server security. This segmentation enables other authorized users to access data from the same copying device while maintaining data protection.
Solution Approach 2:
The patent introduces the copying device as an intermediary between users and the server. Instead of direct server access, users interact with the copying device which then accesses the server on their behalf. This intermediary layer allows multiple users to access data through the copying device while the server maintains security by not exposing direct access to stored data.
2Quantity of substance
If the server stores historical data from multiple information processing devices, then data accumulation is comprehensive, but information protection deteriorates as data from different devices becomes visible to all users
Solution Approach 1:
The patent segments historical data by copying device, with each device maintaining separate historical data in its own storage unit. This segmentation ensures that data from one copying device does not mix with data from other devices, preventing unauthorized cross-device data access while allowing comprehensive data accumulation across the network.
Solution Approach 2:
Each copying device has its own local storage unit that stores historical data specific to that device. This local quality approach ensures that data is stored where it was generated, maintaining data provenance and preventing unauthorized access to data from other devices while still allowing network-wide accessibility through the copying device interface.
3Ease of operation
If users directly access the server to reuse data, then data accessibility improves, but system complexity and permission management deteriorates
Solution Approach 1:
The patent uses the copying device as an intermediary that simplifies access for users. Instead of requiring users to directly access the server and manage complex permissions, users interact with the copying device which handles the server communication automatically. The copying device's control unit manages the interaction with the server, reducing the complexity burden on users.
Solution Approach 2:
The copying device performs self-service by automatically managing its own historical data and handling user requests without requiring direct server access from users. The control unit of the copying device autonomously retrieves data from the server when needed and manages local storage, eliminating the need for users to navigate complex permission structures.
