Context-Aware Authentication for Trusted Device Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack dynamic user authentication mechanisms that prevent unauthorized access when operating outside a secure context, such as when moved from a trusted location or disconnected from a trusted device, potentially allowing unauthorized users to access sensitive information or features.
Innovation Solution
An electronic device is configured to autonomously trigger a second level of authentication when operating outside a secure context, determined by location and connectivity to trusted devices, requiring additional biometric verification for access to specific features or applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If location-based unlock features are implemented to allow the device to remain unlocked at known locations, then convenience for the primary user is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent implements dynamic authentication that adapts security requirements based on device context. The system continuously monitors location, connectivity status, and user presence to dynamically adjust whether authentication is required. This allows the device to be conveniently accessible to the primary user at trusted locations while automatically enforcing security when context changes suggest potential unauthorized access
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring device context (location, network connectivity, sensor data) and using this information to determine authentication requirements. The authentication state is not static but responds to real-time feedback from the environment, allowing the system to maintain security while providing convenience when appropriate
2Speed
If the device is unlocked at known locations to provide convenience, then access speed is improved, but vulnerability to theft or borrowing by unauthorized users increases
Solution Approach 1:
The patent makes authentication requirements dynamic rather than static. The system adjusts security measures in real-time based on contextual factors such as location accuracy, network connectivity to trusted devices, and sensor-detected user presence. This allows fast access when context confirms trusted usage while preventing unauthorized access when context suggests potential security risks
Solution Approach 2:
The system changes security parameters (authentication requirement, authentication method) based on contextual parameters (location, connectivity, sensor data). When contextual parameters indicate a trusted environment, security parameters are relaxed for convenience. When contextual parameters suggest potential unauthorized access, security parameters are tightened to prevent security breaches

AI summary
An electronic device, a method, and a computer program product provide authorization for a user to access functions and applications/application features of the electronic device while the device operates within a secure context and dynamically trigger second level authentication for the user to access secure device functions and applications/application features while the device is operating outside of a secure context. The method includes determining, by a controller of the device, whether the device is being operated in a secure context from among (i) operating within a trusted location and (ii) operating while communicatively connected to a trusted second device. The method includes, in response to determining that the device is not operating in the secure context, activating a second level authentication function that prevents automatic access and requires an additional level of user authentication for access to at least one of specific device operating functions and pre-selected applications/application features.
