Multi-User Document Management with Rights-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current document management tools lack the necessary security and efficiency for managing composite documents in a shared multi-user environment, failing to adequately control access and validation across different users and workstations.
Innovation Solution
A computer system with a document data processing tool, a document data display manager, and a user rights manager, utilizing an object model with access and validation methods, allowing secure access and validation based on user rights, and enabling collaborative document management through a tree diagram interface with tabbed display/input zones, where access and validation status are dynamically managed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current document management tools are used for multi-user composite document management, then basic document access is enabled, but security and control over access and validation are insufficient
Solution Approach 1:
The patent segments document management into distinct functional components: a processing tool for document creation and maintenance, a display manager for presentation and interaction, and a rights manager for security control. Each component handles specific aspects of document management, allowing complex security requirements to be addressed through modular, specialized modules rather than a monolithic system.
Solution Approach 2:
The rights manager acts as an intermediary between users and the document management system, mediating all access and validation operations. It enforces security policies by determining whether users can access specific zones or validate document portions, providing centralized security control without requiring complex security logic throughout the entire system.
2Productivity
If multi-user access to composite documents is enabled, then collaborative work is improved, but control over user access rights and validation rights becomes difficult
Solution Approach 1:
The patent applies local quality by assigning different access rights and validation rights to different users for different zones within a composite document. The rights manager evaluates user credentials against zone-specific security policies, allowing fine-grained control where each document zone can have its own access requirements independent of other zones.
Solution Approach 2:
The rights manager provides universal security control across all users and all document zones through a single centralized component. It handles both access rights determination and validation rights determination, as well as signature authorization, making it a multi-functional security gateway that simplifies operation by providing consistent security management throughout the system.
3Stability of the object's composition
If validation rights are restricted based on user roles, then document integrity is improved, but user flexibility in document modification is reduced
Solution Approach 1:
The system implements dynamic validation control where the rights manager evaluates user credentials, document zone properties, and security policies in real-time to determine validation rights. This allows the system to adaptively grant or deny validation permissions based on the specific context of each user-zone interaction, rather than applying static, one-size-fits-all restrictions.
Solution Approach 2:
The patent changes the parameter of validation control from a binary restricted/unrestricted model to a multi-dimensional evaluation based on user credentials, zone security levels, and document state. The rights manager adjusts validation permissions dynamically by evaluating multiple parameters simultaneously, allowing document integrity to be maintained while preserving user flexibility where appropriate.
4Reliability
If hierarchical validation with level indicators is implemented, then document validation control is improved, but system complexity increases
Solution Approach 1:
The validation mechanism is segmented into hierarchical levels with level indicators assigned to different document zones. Each zone can have its own validation requirements and status tracking, allowing complex validation control to be broken down into manageable, independent level-based units that are evaluated separately by the rights manager.
