Biometric Sensor for Secure Voice Access in Closed Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice recognition systems in portable devices lack secure access mechanisms when in a closed configuration, potentially leading to unintended disclosure of private data due to lack of authentication.
Innovation Solution
Incorporating a biometric authentication system with a sensor on the outer surface of the device that enables voice access only after successful authentication, allowing secure access to predetermined functions while maintaining privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition technology is enabled in lid-closed state, then user convenience is improved, but security of private data deteriorates
Solution Approach 1:
The system performs biometric authentication in advance before enabling voice recognition access. The authentication system verifies the user's identity through biometric data (fingerprint, face, or iris) and only after successful verification does it enable the voice engine to access private data or functions. This preliminary security check prevents unauthorized access while maintaining convenience for authenticated users.
Solution Approach 2:
The authentication system acts as an intermediary between the user and the voice recognition system. It mediates access control by verifying biometric credentials and conditionally enabling or disabling voice engine access based on authentication results. This intermediary layer ensures that voice commands can only access protected resources when the user has been properly verified.
2Adaptability or versatility
If permissions are enabled for voice access to private data, then functionality is improved, but security deteriorates
Solution Approach 1:
The system dynamically adjusts access permissions based on authentication status. When biometric authentication succeeds, the voice engine is enabled to access private data and functions. When authentication fails or is not performed, access is denied. This dynamic permission structure allows the system to be highly functional when needed while maintaining security when authentication is not verified.
Solution Approach 2:
The system changes the access permission parameter based on biometric verification results. The permission state transitions from restricted (default) to granted (after successful authentication). This parameter change enables the system to provide full functionality to authenticated users while maintaining security restrictions for unauthenticated access attempts.

AI summary
Devices, systems and methods for enabling voice access to a portable electronic device in a closed physical configuration with biometric authentication are disclosed. A device can have multiple physical configurations, including a closed configuration in which a display and/or user interface is not accessible. A biometric sensor disposed on an outer surface of the device in at least the closed configuration can be used to enable access to the device or secure functions of the device, via a voice engine or the like, even though the device is physically closed. In some embodiments, unsecure functions can be accessed via voice engine without use of the biometric sensor when the device is closed.
