Mobile App Data Sharing Coordination via Dependency Graphs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device applications are restricted in their ability to communicate with each other due to sandboxing, which limits data sharing and collaboration, and lacks a dynamic mechanism for granting permissions, complicating user experience and security.
Innovation Solution
A method and system for coordinating data sharing among applications on a mobile device by constructing a data trade dependency graph, determining best-matching candidate applications, and automatically recommending data sharing permissions based on optimization rules, allowing applications to share data and resources in a controlled and secure manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If applications are sandboxed for security, then security is improved, but data sharing capability deteriorates
Solution Approach 1:
The patent introduces a data sharing coordination mechanism that acts as an intermediary between sandboxed applications. This mechanism includes a data sharing manager that constructs dependency graphs and determines permission configurations, enabling secure data sharing without breaking the sandbox architecture. The intermediary layer resolves the contradiction by providing controlled access paths while maintaining isolation boundaries.
Solution Approach 2:
The patent implements dynamic permission configuration that allows data sharing relationships to be established and modified at runtime based on application needs. The system dynamically determines permission configurations by analyzing data trade dependency graphs, enabling flexible data sharing while maintaining security constraints. This dynamic approach resolves the static nature of traditional sandboxing.
2Reliability
If static permission declaration is required for security, then security is improved, but user experience deteriorates
Solution Approach 1:
The patent performs preliminary analysis by constructing data trade dependency graphs that identify required data sharing permissions before user interaction. The system pre-determines optimal permission configurations based on application functionality requirements, so that when users are prompted for permission, the requested permissions are already optimized and necessary, reducing unnecessary permission requests and improving user experience while maintaining security.
Solution Approach 2:
The patent implements a feedback mechanism where the system monitors data sharing patterns and application performance, then uses this information to refine permission configurations. The data sharing coordination mechanism learns from usage patterns and adjusts permission grants accordingly, providing better user experience over time while maintaining security through continuous optimization based on actual needs.
3Reliability
If applications cannot access other applications' sandboxes, then security is improved, but application functionality deteriorates
Solution Approach 1:
The patent segments data access permissions into fine-grained categories based on specific data types and access patterns. Instead of all-or-nothing access between sandboxes, the system divides data access into discrete, controllable units that can be selectively granted. This segmentation allows applications to access only the specific data they need from other applications, maintaining security while enabling necessary functionality.
Solution Approach 2:
The patent creates a universal data sharing coordination mechanism that serves multiple functions: constructing dependency graphs, determining permission configurations, analyzing data conflicts, and recommending optimal sharing arrangements. This multi-functional system resolves various data sharing scenarios within a unified framework, enabling diverse application functionality while maintaining consistent security policies across different data access patterns.
