Wearable Device Persistent Authentication with Biometric Disablement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication systems, particularly in alarm monitoring systems, face security risks due to the need for manual interaction and the potential for loss or theft of wearable devices that store multiple permissions, leading to unauthorized access when the user is not carrying the device.
Innovation Solution
A wearable device that provides persistent authentication with conditional disablement based on physical changes, such as contact or separation, electrical signals, or biometric characteristics, ensuring that permissions are revoked when the user is no longer in possession, thereby enhancing security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable device stores multiple permissions for persistent authentication, then user convenience is improved by consolidating authentication codes in a single device, but security is worsened due to the risk of loss or theft providing unauthorized access
Solution Approach 1:
The patent implements dynamic authentication states by transitioning the wearable device between enabled and disabled states based on biometric verification. The system dynamically adjusts the authentication mechanism from passive permission storage to active biometric-controlled permission granting, ensuring that stolen devices cannot be used without the original user's biometric data.
Solution Approach 2:
The system employs self-service authentication where the wearable device automatically verifies biometric characteristics and manages permission granting without requiring manual user intervention. The device autonomously determines whether to enable or disable permissions based on biometric matching, eliminating the need for users to manually manage multiple authentication codes.
2Reliability
If manual interaction is required to use stored permissions, then security is improved by requiring user initiation, but convenience is worsened by requiring users to actively launch applications or present the device
Solution Approach 1:
The patent implements self-service authentication where the wearable device automatically performs biometric verification and permission granting without requiring manual user actions. The system continuously monitors for authorized users through biometric sensing and automatically activates permissions when the correct user is detected, eliminating the need for users to launch applications or manually present the device.
Solution Approach 2:
The system performs preliminary biometric verification and authentication setup in advance, storing permission-granting capabilities within the wearable device before actual authentication events occur. This preliminary configuration allows the device to automatically grant or deny permissions based on pre-stored biometric templates, eliminating the need for real-time manual intervention.
Data Source
AI summary
The invention relates to a method and wearable device for persistent authentication using the wearable device. The wearable device is activated in response to an enablement indication, the enablement indication being generated in response to a physical change in the wearable device. A permission is granted in response to authorization data. The wearable device is deactivated in response to a disablement indication, the disablement indication being generated in response to a physical change in the wearable device. The permission may also be revoked.
