Wearable Fingerprint Authentication for Hands-Free Speech Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to access speech recognition functions on mobile devices while wearing Bluetooth headsets, as they need to frequently interact with the phone for identity authentication, especially in scenarios where it's difficult to operate the device, such as being far away from it.
Innovation Solution
A method where a Bluetooth headset collects a fingerprint pattern and speech input from the user, performs authentication, and then enables corresponding functions on the mobile phone wirelessly, allowing the phone to execute commands without requiring direct user interaction, ensuring security through pre-stored fingerprints and potential cloud server verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile phone performs authentication on user identity before enabling speech recognition function, then security is improved, but ease of operation deteriorates because the user needs to frequently interact with the phone for authentication
Solution Approach 1:
The system performs user identity authentication in advance by collecting fingerprint patterns from the wearable device before the speech recognition function is activated. The mobile phone receives and stores the fingerprint data, then automatically verifies user identity when speech input is detected, eliminating the need for repeated manual authentication operations.
Solution Approach 2:
The wearable device serves as an intermediary that collects and transmits fingerprint authentication data to the mobile phone. This mediator enables automatic background authentication without requiring direct user interaction with the mobile phone, resolving the contradiction between security verification and operational convenience.
2Measurement precision
If the user operates the mobile phone for identity authentication, then authentication accuracy is improved, but loss of time increases due to frequent interactions required
Solution Approach 1:
The system collects and pre-processes fingerprint authentication data from the wearable device before speech recognition is needed. The mobile phone receives the fingerprint pattern in advance, performs initial verification, and stores authentication status, enabling rapid automatic verification when speech input occurs without requiring time-consuming manual operations.
Solution Approach 2:
The system performs automatic authentication verification using pre-collected fingerprint data from the wearable device. When speech input is detected, the mobile phone automatically retrieves stored fingerprint information, verifies user identity without manual intervention, and activates speech recognition functions, eliminating time loss from repeated user operations.
3Ease of operation
If the Bluetooth headset collects fingerprint pattern and performs authentication, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The wearable device acts as an intermediary that collects fingerprint patterns and transmits them to the mobile phone for authentication processing. This mediator approach enables the wearable device to gather biometric data without requiring complex authentication algorithms, while the mobile phone handles the computational complexity of fingerprint verification and speech recognition activation.
Solution Approach 2:
The authentication system is segmented into distinct functional modules: the wearable device collects fingerprint patterns and transmits them wirelessly, the mobile phone receives and verifies the authentication data, and the speech recognition function is activated based on verification results. This segmentation distributes complexity across multiple devices, maintaining ease of operation while managing system complexity.
Data Source
AI summary
A wearable device collects a fingerprint pattern input by a user and speech input by the user. The wearable device sends the fingerprint pattern to an electronic device, to enable the electronic device to perform authentication on the fingerprint pattern input by a user. The wearable device sends the speech to the electronic device, and, upon a determination that the authentication succeeds, the electronic device is enabled to execute a function corresponding to the speech.
