Wearable Biometric Token Management via Invalidating Event Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices are limited in capability and impractical for embedding biometric scanning devices, making it difficult to maintain biometric information securely without scanning, and existing methods do not prevent unauthorized use.
Innovation Solution
A wearable device manages a biometric token that includes a device identifier, biometric templates, and validity status, using detectors to invalidate the token upon invalidating events such as detachment or location changes, ensuring trust in the associated identity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric scanning devices are embedded in wearable devices, then biometric information can be captured and verified, but the device complexity and size increase significantly
Solution Approach 1:
The patent extracts the biometric scanning function from the wearable device itself and places it in an external authentication system. The wearable device only stores biometric templates and tokens, while the actual scanning and verification are performed by separate authentication devices, thus reducing the complexity and size requirements of the wearable device while maintaining biometric verification reliability
Solution Approach 2:
The patent introduces biometric tokens as an intermediary between the wearable device and the authentication system. These tokens contain encrypted biometric templates and are verified by external systems, allowing the wearable device to provide authentication capabilities without embedding complex scanning hardware
2Ease of operation
If biometric tokens are stored on the wearable device, then identity verification is enabled, but security risks increase from unauthorized access
Solution Approach 1:
The patent implements preliminary actions by detecting invalidating events (detachment, water exposure, impact) before unauthorized access can occur. When such events are detected, the biometric token is proactively invalidated, preventing potential security breaches while maintaining ease of operation during normal use
Solution Approach 2:
The patent employs feedback mechanisms where the wearable device continuously monitors for invalidating events and provides real-time updates to the authentication system. This feedback loop allows the system to respond dynamically to security threats by invalidating tokens when compromise is detected, balancing accessibility with security
3Duration of action of stationary object
If the biometric token remains valid indefinitely, then continuous access is provided, but security is compromised if the device is lost or stolen
Solution Approach 1:
The patent makes the token validity dynamic rather than static. The biometric token's validity status changes based on monitored conditions - it remains valid during normal use but is automatically invalidated when invalidating events are detected. This dynamic approach allows continuous access during legitimate use while providing security protection if the device is lost or stolen

AI summary
A wearable device may store a biometric token associated with a wearer of the wearable device, the wearable device including: a wireless communications interface; a processing circuitry; a memory configured to store a biometric token associated with a wearer of the wearable device, the biometric token including a device identifier that is associated with the wearable device, a biometric template for each of one or more biometric scans of the wearer of the wearable device, and an indication of whether or not the biometric token is valid, wherein the biometric token, if valid, establishes a trust that wearer identifying information, linked to the biometric token, is associated with the wearer; an invalidating event detector configured to determine if an invalidating event has occurred; wherein the processing circuitry is configured to invalidate the biometric token in response to detecting that an invalidating event has occurred for the biometric token.
