Wearable Device Vein Image Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices lack efficient and secure methods for user authentication and personalized functionality management, relying on manual inputs or less secure biometric methods.
Innovation Solution
A wearable device equipped with a sensor to capture vein images and a processor that compares the captured images with registered ones for authentication, enabling secure execution of functions and settings tailored to the identified user, including wireless communication, contact lists, music lists, and social media login.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input methods are used for user authentication, then device operation is simple, but security and convenience are insufficient
Solution Approach 1:
The patent replaces manual mechanical input methods (typing passwords, physical key entry) with an optical/biological authentication system. The sensor captures vein images of the user's hand, and the processor compares these images against stored templates to authenticate the user. This substitution eliminates the need for manual typing while providing secure authentication, thereby improving both security and convenience simultaneously.
2Reliability
If biometric authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent extracts the authentication functionality into a separate, modular component system. The sensor module captures vein images, the processor module compares images against stored templates, and the execution module determines whether to allow access. This extraction organizes the complex biometric authentication system into distinct functional units, making the overall system more manageable and easier to implement while maintaining high security.
3Measurement precision
If vein image capture is used for authentication, then user identification accuracy is improved, but the need for additional sensors and processing increases complexity
Solution Approach 1:
The patent implements a multi-functional sensor system that serves multiple purposes. The same sensor used to capture vein images for authentication can also be used to display user-specific information such as contact lists, music playlists, and notifications. This multi-functionality justifies the addition of the sensor and processing capabilities, as the hardware serves both security and user experience functions, thereby improving identification accuracy while managing the complexity through versatile component usage.

AI summary
A wearable device includes: a sensor configured to capture a vein image of a user; and a processor configured to control the sensor to capture the vein image of the user wearing the wearable device when a function or an application is selected, identify the user by comparing the captured vein image with at least one registered vein image, and execute the function or the application when the user has execution authority.
