In-Vehicle Biometric Unlocking for Secure Driver Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive devices lack an efficient method for user authentication during driving, as manual password entry or complex identity recognition is impractical while operating a vehicle, necessitating an improved solution for secure access to integrated smart applications.
Innovation Solution
An automotive device featuring a first sensing unit for sensing a biological feature, such as face recognition, and a second sensing unit for sensing a different biological feature, like fingerprint recognition, with a processing unit to receive and evaluate key signals from both, determining whether to unlock the device for secure access without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual password entry or complex identity recognition is used, then information security is improved, but ease of operation deteriorates during driving
Solution Approach 1:
The patent replaces manual mechanical operations (typing passwords, physical key entry) with automatic biometric sensing systems. The sensing units detect biological features (fingerprint, face recognition, iris) and automatically generate authentication signals, eliminating the need for manual driver intervention while maintaining strong security through multiple biometric modalities.
Solution Approach 2:
The system enables self-service authentication where the driver's biological features are automatically detected and processed without requiring active participation. The sensing units continuously monitor for presence and automatically attempt authentication when the driver approaches or enters the vehicle, allowing the system to serve itself rather than requiring manual operation.
2Reliability
If multiple sensing units are integrated, then information security is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing units (fingerprint sensor, face recognition camera, iris scanner) and integrates them with the vehicle's existing control systems through a centralized processing unit. This merging approach allows the system to leverage multiple authentication modalities while sharing hardware resources and processing capabilities, reducing overall system complexity compared to separate independent systems.
Solution Approach 2:
The sensing units are designed with multi-functionality to serve both authentication purposes and other vehicle functions. For example, the face recognition system can be used for both driver identification and monitoring driver fatigue or distraction, allowing the same hardware to perform multiple roles and reducing the need for dedicated components for each function.

AI summary
An automotive device includes a first sensing unit, a second sensing unit and a processing unit. The first sensing unit is used to sense a first biological feature, and generate a first key signal according to the first biological feature. The second sensing unit is used to sense a second biological feature different from the first biological feature, and generate a second key signal according to the second biological feature. The processing unit is electrically connected with the first sensing unit and the second sensing unit. The processing unit receives at least one of the first key signal and the second key signal, and determines whether to unlock the automotive device according to the at least one of the first key signal and the second key signal.
