Earphone Authentication Management Using Proximity Sensor Wearing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems for wearable devices, such as those described in Patent Document 1, lack control over the authentication state, particularly in determining whether the device is worn by the user, which affects the accuracy and security of biometric authentication.
Innovation Solution
An authentication management device that includes an authentication result acquisition means for otoacoustic authentication, a storage means to store the authentication result, a determination result acquisition means using a proximity sensor to determine if the earphone is worn, and a control means to update the authentication result when the earphone is not worn, ensuring accurate and secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If biometric authentication is performed without checking wearing state, then authentication speed is improved, but authentication accuracy deteriorates
Solution Approach 1:
The system performs a preliminary wearing state determination using the proximity sensor before executing the biometric authentication. This preliminary check ensures that the earphone is actually worn on the user's ear, preventing inaccurate authentication attempts and improving overall authentication accuracy without significantly impacting speed.
Solution Approach 2:
The system continuously monitors the wearing state through the proximity sensor and uses this feedback to control the authentication process. When the proximity sensor detects that the earphone is not worn, the system can cancel or adjust the authentication, creating a closed-loop control that maintains high accuracy while preserving speed.
2Measurement precision
If continuous monitoring of wearing state is performed, then authentication accuracy is improved, but battery consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic monitoring of the wearing state through the proximity sensor. The sensor is activated at specific intervals or trigger events (such as authentication requests) rather than continuously, significantly reducing power consumption while maintaining sufficient monitoring for accurate authentication control.
Solution Approach 2:
The proximity sensor automatically detects the wearing state without requiring active user input or continuous system intervention. The sensor passively monitors the presence of the earphone in the ear and provides this information to the control unit, enabling the system to manage authentication states autonomously with minimal energy expenditure.

Function Achieved in This Case
This solution enables fast and secure control of the user authentication state based on the wearing state of the earphones, enhancing authentication accuracy and reducing battery consumption by periodically checking the wearing state.
Implementation Method 1
a wearing determination result indicating whether the earphone is worn in an ear of the user on the basis of a detection result of a proximity sensor
Implementation Method 2
an authentication result acquisition means that acquires a result of authenticating a user by otoacoustic authentication in an earphone
Data Source
AI summary
An authentication management device acquires a result of authenticating a user by otoacoustic authentication in an earphone; stores the authentication result; after the authentication result is acquired, acquires a wearing determination result indicating whether the earphone is worn in an ear of the user on the basis of a detection result of a proximity sensor; and updates the stored authentication result when the wearing determination result indicates that the earphone is not worn in the ear.
