Context-Based Document Access Control for Insider Threat Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document management systems rely on role-based access control (RBAC) which can be bypassed, exposing them to unauthorized access, necessitating improved access control mechanisms.
Innovation Solution
Implementing a context-based access control system that uses machine learning to analyze user and document context information, including document-valuation, shareability, and user-cooperation properties, to identify suspicious activities and perform authentication when necessary, independent of user rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If role-based access control (RBAC) is used to control document access, then ease of operation is improved, but reliability deteriorates due to vulnerability to unauthorized access
Solution Approach 1:
The patent introduces a context-based access control system that acts as an intermediary layer between the user and the document management system. This intermediary evaluates multiple context factors (device type, location, time, document sensitivity) before granting access, thereby maintaining ease of operation for legitimate users while enhancing security against unauthorized access through dynamic context verification.
Solution Approach 2:
The system dynamically changes access parameters based on context evaluation. Instead of static role-based permissions, the access control decisions are made by evaluating multiple contextual parameters in real-time, allowing the system to adapt security levels according to the specific access situation while maintaining user convenience for normal operations.
2Reliability
If authentication is performed for every document access request, then reliability is improved, but productivity deteriorates due to increased authentication overhead
Solution Approach 1:
The system applies partial authentication action by performing context-based access control evaluations only when necessary. Instead of requiring full authentication for every document access request, the system performs lightweight context verification for routine accesses and reserves full authentication for suspicious or high-risk scenarios, thereby maintaining security while preserving user productivity.
Solution Approach 2:
The context-based access control system operates continuously in the background, evaluating context factors without interrupting the user workflow. By performing access control checks as part of the normal document access process rather than as separate authentication steps, the system maintains both security and user efficiency.

AI summary
A document management system having context-based access control and related methods are provided. The document management system determines whether to perform user authentication based on derived context-information comprising one or a combination of derived user-context parameters and document-context parameters that provide additional context to document access requests.
