Context-Aware Document Management System for Mobile Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current document management systems fail to effectively filter and deliver relevant information to users in mobile work contexts, leading to information overload and challenges in managing document confidentiality and security, especially in scenarios involving physical mobility and collaboration among workers with diverse roles.
Innovation Solution
A computer-implemented system that links digital documents to a physical context using three dimensions of data: location, time, and social components, allowing for constrained actions such as read/write access, and automatically filters and delivers relevant information based on the user's context, using mobile devices to capture and transmit context information for access control and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If document management systems provide permanent and ubiquitous data access, then information availability is improved, but information overload increases
Solution Approach 1:
The patent applies local quality by customizing document access and visibility based on specific user contexts (location, time, role, device). Instead of uniform access for all users, the system dynamically adjusts what documents are available to each user based on their current context, thereby maintaining information availability while filtering out irrelevant information that contributes to overload.
Solution Approach 2:
The system changes multiple parameters simultaneously (location, time, user role, device type, network environment) to dynamically determine document accessibility. By monitoring and responding to changes in these parameters, the system provides appropriate information at the right context without overwhelming users with all available documents regardless of their current situation.
2Quantity of substance
If document access is contextualized based on multiple parameters, then information overload is reduced, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining context profiles and document access rules for different situations. Instead of making complex real-time decisions for every access request, the system has previously configured context parameters and corresponding document visibility rules, allowing it to efficiently evaluate user contexts against predefined criteria and reduce computational complexity at runtime.
Solution Approach 2:
The system employs a universal context evaluation framework that handles multiple context parameters (location, time, user role, device, network) through a single integrated mechanism. This multi-functional approach allows the same core system to manage diverse contextual factors without requiring separate complex subsystems for each parameter, thereby reducing overall system complexity.
3Ease of operation
If mobile devices are used for document access in both private and work contexts, then accessibility is improved, but document security and confidentiality management becomes more difficult
Solution Approach 1:
The patent applies dynamics by making document access rights fluid and context-dependent rather than static. Access control decisions are dynamically adjusted based on the user's current context (work vs. private mode, location, time, device). This allows the same mobile device to provide easy access to appropriate documents while automatically restricting access to sensitive documents when context indicates potential security risks, thereby maintaining both accessibility and security.
Data Source
AI summary
Methods, systems, and computer-readable media for digital document management. A physical context can be identified, wherein such a physical context includes three dimensions of data. One or more digital documents can be automatically linked to the physical context, after identifying the physical context. Constraints can then be combined, which are derived from the three dimensions of data, allow particular actions with respect to the digital document(s). The three dimensions of data include, for example, data indicative of location, time, and a social component (e.g., people present at a location). Actions with respect to the digital document can include, for example: an allowed action, a restricted action, or a prohibited action (e.g., read/write).
