Common User ID for Distributed Document Access Rights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In document management systems with multiple independent apparatuses, accessing rights management becomes complex and burdensome when documents are distributed, moved, or integrated across these systems, as user IDs are independently managed and not universally recognized.
Innovation Solution
A document management system that employs a user ID generating apparatus external to the document managing apparatuses to create a common user ID shared among them, facilitating access rights management by synchronizing user IDs across multiple systems through an export and import mechanism for documents and access control lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user IDs are independently managed for each document managing apparatus, then each apparatus can operate autonomously, but access rights management becomes complex and burdensome when documents are distributed or moved between apparatuses
Solution Approach 1:
The patent introduces a common user ID system that acts as an intermediary between multiple independent document managing apparatuses. Instead of direct peer-to-peer authentication, all apparatuses reference a shared user ID space, enabling autonomous operation while maintaining consistent access rights management across the distributed system.
Solution Approach 2:
The patent implements a universal user ID system that functions across multiple independent document managing apparatuses. The same user ID can be used to access documents on any apparatus in the system, eliminating the need for separate authentication systems and simplifying access rights management when documents are distributed or moved between apparatuses.
2Ease of operation
If documents are distributed or moved between document managing apparatuses, then document accessibility is improved, but reassignment of access rights becomes extremely troublesome and complex
Solution Approach 1:
The patent establishes user IDs and access rights in advance using a common identification system before documents are distributed or moved between apparatuses. By pre-configuring the user ID space and access control lists with the understanding that documents may move, the system eliminates the need for time-consuming reassignment operations when distribution occurs.
Solution Approach 2:
The common user ID system serves as an intermediary that maintains access rights consistency during document distribution. When documents are moved between apparatuses, the intermediary user ID system automatically maintains the appropriate access permissions without requiring manual reassignment, thus saving time and reducing complexity.
3Ease of operation
If a common user ID system is implemented across multiple apparatuses, then access rights management is simplified, but the system architecture becomes more complex
Solution Approach 1:
The patent segments the system into independent document managing apparatuses that each maintain their own document storage and local access control lists, while sharing a common user ID space. This segmentation allows each apparatus to operate autonomously with simplified local architecture, while the common user ID system provides unified access rights management across the distributed system.
Data Source
AI summary
A document managing system is provided with a plurality of document managing apparatuses each configured to retrieve a document stored in a storage according to a document ID and to judge whether or not an operation with respect to the retrieved document is possible according to a user ID that is generated with respect to each document managing apparatus, and a user ID generating apparatus provided externally to the document managing apparatuses and configured to generate a common user ID that is used in common among each of the document managing apparatuses. Each document managing apparatus has an export and import part configured to export and import data of an arbitrary document and an access control list (ACL).
