Dynamic Context-Based Data Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data access management systems rely on static access control lists that do not adapt to changes in the data access environment, leading to potential security vulnerabilities.
Innovation Solution
A method that dynamically manages data access by capturing current context signals during each access request, comparing them to predetermined reference data based on authorization policies, and making access decisions based on dynamic data access policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static access control lists are used to manage data access, then the system is simple to implement and easy to operate, but the security deteriorates over time as the access environment changes
Solution Approach 1:
The patent implements dynamic access control by evaluating context signals (location, time, device state, user behavior) at the moment of each data access request, replacing static ACLs with a dynamic decision-making system that adapts to changing environments while maintaining ease of use through automated context evaluation
2Reliability
If dynamic context-based access control is implemented, then the security improves by adapting to current environment, but the device complexity increases due to context capture and comparison mechanisms
Solution Approach 1:
The patent introduces a context evaluation module as an intermediary component that captures context signals, compares them against reference data, and feeds results to the access decision engine, thereby managing the complexity of dynamic security through a structured intermediate layer rather than embedding all logic directly in the access control system
3Reliability
If real-time context comparison is performed for each data access request, then the data protection improves, but the processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-establishing reference data for context signals and pre-defining access policies during system setup, so that during actual data access requests, the system only needs to compare current context against pre-existing references rather than performing complex analyses in real-time, thus reducing processing time while maintaining strong data protection
