Dynamic Access Control Adjusting Security Levels by Task Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for dynamically adjusting security levels based on contextual information are insufficiently optimal, failing to effectively tailor access control to the specific tasks and contexts in which resources are accessed.
Innovation Solution
A system comprising an identification subsystem, an access control subsystem, and a task interface that determines security measures based on the task to be completed, adjusting the level of security dynamically by considering factors like task relevance, user role, location, and occurrence frequency, to provide varying levels of access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If security measures are dynamically adjusted based on contextual information, then adaptability of access control is improved, but optimization of security adjustment is insufficient
Solution Approach 1:
The system dynamically adjusts security measures based on task characteristics and contextual information. The access control subsystem modifies authentication requirements in real-time according to the specific task being performed, transitioning from static to dynamic security adjustment to resolve the contradiction between adaptability and optimization.
Solution Approach 2:
The system changes security parameters (authentication level, security measures) based on task parameters and contextual factors. By linking security level to task-specific parameters rather than using fixed thresholds, the system achieves both adaptability and optimal security adjustment.
2Ease of operation
If security measures are adjusted based on task relevance, then ease of operation is improved for relevant tasks, but security stringency may be reduced for less relevant tasks
Solution Approach 1:
The system applies different security measures locally based on task characteristics. High-security measures are applied only when task relevance and contextual factors indicate potential risk, while low-security or no-security measures are applied when task relevance is high and context is trustworthy, achieving both ease of operation and maintained security stringency where needed.

AI summary
A system is provided for controling access to a resource, the access being restricted by an access mechanism. The system comprises an access control subsystem for i) subjecting the user to one or more security measures based on use of a security input system, and ii) signaling the access mechanism to grant the user access to the resource based on the user passing the one or more security measures. The system further comprises a task interlace for accessing task data, the task data being indicative of a scheduled task of the user. The access control subsystem is further arranged for determining the one or more security measures based on the scheduled task to establish different levels of security depending on the task. Advantageously, a better adjusting of the level of security is obtained in that it is dynamically adjusted to the scheduled task of the user.
