Wearable Electronic Key With Biometric Wearer Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic key systems for vehicles and residential facilities are vulnerable to unauthorized use if the portable key is lost or stolen, as anyone possessing the key can unlock and potentially misuse the protected object.
Innovation Solution
A wearable key device that includes a ring communication module, an imaging device, and a ring controller, which captures biometric information of the wearer and wirelessly communicates with an authentication device to verify authorized users, preventing the key from being used by unauthorized individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional portable electronic keys are used for wireless communication with authentication devices, then ease of operation is improved, but security against unauthorized use deteriorates
Solution Approach 1:
The patent combines the portable electronic key with a biometric authentication device (imaging device) into an integrated system. The imaging device captures biometric information (fingerprint, facial recognition, or iris pattern) and the ring controller verifies this information against stored data, ensuring that only the authorized user can activate the key function, thus resolving the security vulnerability of conventional portable keys
Solution Approach 2:
The patent introduces biometric information as an intermediary verification layer between the user and the authentication device. The ring controller acts as a mediator that captures biometric data, compares it with stored information, and only then permits wireless communication with the authentication device, adding a security checkpoint that prevents unauthorized use
2Reliability
If biometric authentication is added to the wearable key device, then security is improved, but device complexity increases
Solution Approach 1:
The ring controller is designed with multi-functionality, serving both as a wireless communication interface for authentication and as a biometric verification system. The imaging device can capture multiple types of biometric information (fingerprint, facial recognition, iris pattern), making the system versatile while consolidating functions into a single wearable device rather than requiring separate systems
Solution Approach 2:
The wearable key device performs self-authentication by capturing and verifying its own wearer's biometric information through the imaging device and ring controller. The device autonomously compares captured biometric data with stored information and determines whether to enable key functions, reducing the need for external verification systems and simplifying the overall authentication architecture

AI summary
A wearable key device is to be used while being worn on a predetermined position of a body and includes a ring communication module, an imaging device, and a ring controller. The ring communication module is configured to wirelessly communicate with an authentication device provided to a predetermined protection object. The imaging device is configured to capture an image of the predetermined position of the body. The ring controller is configured to acquire wearer information that is biometric information of a wearer who wears the wearable key device based on the image captured by the imaging device. The wearer information is used for determining whether the wearer is an authorized user.
