Wearable Device Biometric Authentication During Donning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices require frequent password entry for authentication, which is cumbersome and obtrusive, especially for devices with small keys or touch screens, hindering efficiency and user experience.
Innovation Solution
Integration of a user authentication sensor that senses biometric characteristics during the natural motion of donning the device, such as a fingerprint sensor on a wristband or headset, allowing automatic authentication without additional steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password authentication system is implemented for security, then unauthorized access is prevented, but user convenience deteriorates due to frequent password entry requirements
Solution Approach 1:
The system performs authentication in advance by capturing biometric data during the natural act of donning the device. The biometric sensor is positioned to automatically sense the user's fingerprint or other biometric characteristic when the device is being put on, completing authentication before the device is fully worn. This eliminates the need for subsequent password entries during device usage.
Solution Approach 2:
The authentication process is integrated into the natural donning motion itself. The act of putting on the device automatically triggers biometric sensing and authentication without requiring the user to perform separate authentication actions. The system serves itself by utilizing the inherent motion of device donning to complete the authentication process.
2Reliability
If traditional password authentication is used, then security is maintained, but time consumption increases due to frequent authentication requirements
Solution Approach 1:
Authentication is performed in advance during the donning process rather than requiring separate authentication actions later. The biometric sensor captures and processes authentication data before the device is fully worn, eliminating subsequent authentication delays during device usage.
Solution Approach 2:
The authentication process is merged with the natural donning motion. Instead of being separate sequential steps, authentication and device donning occur simultaneously, utilizing the same time period and user action to accomplish both tasks.
3Ease of operation
If a biometric sensor is integrated into the wearable device, then authentication convenience is improved, but device complexity increases
Solution Approach 1:
The biometric sensor serves multiple functions: it authenticates the user during donning, can potentially monitor biometric data during wear, and integrates with the existing device structure. This multi-functionality justifies the added complexity by providing enhanced authentication convenience and potential additional health or security features.
