Adaptive Access Control System for Cognitive State Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control methods fail to dynamically adjust access tasks based on changes in user behavior and cognitive state, leading to potential distractions and negative impacts on user well-being and device performance.
Innovation Solution
An apparatus and method that control access to resources by switching between different access tasks based on user responses, where the initiation of the change is causally independent of the user's previous response and dependent on changes in monitored parameters such as time, location, and biometric data, to adapt to varying cognitive control states and usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access tasks are used to protect resource access, then security and access control are improved, but user interaction time and potential distractions increase
Solution Approach 1:
The access task system dynamically adjusts task parameters based on monitored user cognitive state. When the system detects that the user is in a high cognitive control state, it presents more challenging access tasks. When the user is in a low cognitive control state, the system presents simpler tasks or reduces task frequency, thereby maintaining security while minimizing interaction time and distractions.
Solution Approach 2:
The system changes parameters of access tasks based on monitored user state. This includes adjusting task complexity, response time requirements, and task frequency according to the user's cognitive control state, allowing the system to optimize between security and user well-being by adapting task parameters in real-time.
2Reliability
If access tasks are continuously presented to users, then access control is maintained, but user well-being and cognitive load are negatively impacted
Solution Approach 1:
The system continuously monitors user cognitive state through various parameters (eye tracking, response time, interaction patterns) and uses this feedback to adjust access task presentation. This closed-loop feedback mechanism allows the system to maintain access control while adapting to user cognitive load, preventing excessive cognitive strain by reducing or simplifying tasks when users show signs of cognitive fatigue.
Solution Approach 2:
The access control system transitions from a static, fixed-task approach to a dynamic system that continuously adapts task parameters based on real-time user state monitoring. This dynamic adjustment ensures that access control is maintained while minimizing negative impacts on user well-being by presenting tasks only when appropriate and adjusting their complexity to match user capacity.
3Loss of time
If access tasks are simplified for faster completion, then user interaction time is reduced, but access security and reliability are compromised
Solution Approach 1:
The system changes the parameters of access tasks based on the user's cognitive control state. When the user is in a high cognitive control state, the system presents more complex and secure access tasks. When the user is in a low cognitive control state, the system presents simpler tasks that can be completed quickly, thus optimizing the balance between security and interaction time dynamically rather than using a fixed approach.

AI summary
An apparatus comprising means for, a method comprising, and a computer program that performs: at a first time, controlling whether or not a user is granted access to at least one resource based on an obtained response of the user to a first access task; at the first time, setting one or more restrictions on granted access to the at least one resource based on the obtained response of the user to the first access task; at a second time, controlling whether or not the user is granted access to the at least one resource based on an obtained response of the user to a second access task, different to the first access task; at the second time, setting one or more restrictions on granted access to the at least one resource based on the obtained response of the user to the second access task; and initiating a change from the first access task to the second access task, wherein the initiation of the change is causally independent of the obtained response of the user to the first access task.
