Wearable Device Wireless Access Certificate Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased use of mobile devices, especially wearable devices, poses security and access concerns as they can be paired with primary devices like smartphones, leading to unauthorized access if not properly secured.
Innovation Solution
A mechanism where a wearable device detects when it is being worn and establishes a secure wireless link with a primary device, allowing access and then erases the access certificate if the wearable device is removed or the link is disconnected, ensuring only authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wearable device is paired with a primary device to enable wireless access, then convenience and ease of operation are improved, but security risks and unauthorized access potential increase
Solution Approach 1:
The patent implements dynamic certificate management where the access certificate is automatically generated, stored, and invalidated based on real-time wear detection status. The system transitions between authorized and unauthorized states dynamically, enabling convenient access when worn while preventing unauthorized use when removed.
Solution Approach 2:
The wear detection mechanism provides continuous feedback to the security system about the physical state of the wearable device. This feedback loop enables the system to automatically adjust access permissions based on whether the device is being worn, resolving the contradiction between convenience and security.
2Ease of operation
If access certificates are stored in the wearable device for continuous access, then ease of operation is improved, but device loss or theft becomes more dangerous
Solution Approach 1:
The patent changes the validity parameter of the access certificate based on the wear detection status. When the device is not worn, the certificate automatically becomes invalid and is erased from storage. This parameter change ensures continuous convenient access when worn while eliminating the vulnerability associated with device loss or theft.
3Reliability
If wear detection mechanisms are added to the wearable device, then security is improved, but device complexity increases
Solution Approach 1:
The wear detection system operates autonomously, automatically detecting whether the device is being worn and triggering the appropriate security response without user intervention. This self-service approach improves security while minimizing the perceived complexity for the user.
Solution Approach 2:
The patent replaces complex mechanical wear detection systems with electronic or electromagnetic sensing mechanisms. This substitution maintains security functionality while reducing mechanical complexity and improving reliability.

AI summary
A method of operation includes detecting that a wearable device is being worn, receiving a certificate from a primary device over a secure wireless link where the wearable device is paired to the primary device using the secure wireless link, storing the certificate in memory of the wearable device, and sending the certificate, over the secure wireless link, to the primary device to unlock the primary device. The method may further include detecting that the wearable device is no longer being worn, and eradicating the certificate from memory of the wearable device in response to detecting that the wearable device is no longer being worn. In some embodiments, the method may also include detecting that the secure wireless link is disconnected, and eradicating the certificate from memory of the wearable device in response to detecting that the secure wireless link is disconnected. The present disclosure also provides a wearable device.
