BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18483843 titled 'BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM
Simplified Explanation
The patent application describes a biometric authentication device that uses both ear and voice authentication to verify the identity of a user. Here are the key points:
- The device includes a replay unit that can reproduce a sound.
- An ear authentication unit captures the reverberation sound of the reproduced sound in the user's ear. It extracts an ear acoustic feature from the reverberation sound and compares it with a stored ear acoustic feature to calculate an ear authentication score.
- A voice authentication unit extracts a talker feature from the user's voice input and compares it with a stored talker feature to calculate a voice authentication score.
- An authentication integration unit combines the ear authentication score and the voice authentication score to generate an authentication integration result.
- The device also includes a recording unit that can input the voice of the user after the sound is output into the ear.
Potential applications of this technology:
- Biometric authentication: The device can be used for secure access control systems, such as unlocking devices, accessing restricted areas, or authorizing transactions.
- Identity verification: It can be used in applications where verifying the identity of a user is crucial, such as online banking, e-commerce, or government services.
- Fraud prevention: The device can help prevent impersonation or fraud by ensuring that the person using the device is the authorized user.
Problems solved by this technology:
- Enhanced security: By combining both ear and voice authentication, the device provides a more robust and accurate method of verifying a user's identity compared to traditional methods like passwords or PINs.
- Anti-spoofing: The use of ear and voice authentication helps prevent spoofing attempts, as it is difficult for an unauthorized person to replicate both the ear acoustic feature and the talker feature of the authorized user.
Benefits of this technology:
- Convenience: Users can authenticate themselves by simply listening to a sound and speaking, eliminating the need for remembering and entering complex passwords.
- Accuracy: The combination of ear and voice authentication provides a higher level of accuracy in verifying the user's identity, reducing the chances of false positives or false negatives.
- Enhanced security: The device offers a more secure authentication method, reducing the risk of unauthorized access or identity theft.
Original Abstract Submitted
A biometric authentication device is provided with: a replay unit for reproducing a sound; an ear authentication unit for acquiring a reverberation sound of the sound in an ear of a user to be authenticated, extracting an ear acoustic feature from the reverberation sound, and calculating an ear authentication score by comparing the extracted ear acoustic feature with an ear acoustic feature stored in advance; a voice authentication unit for extracting a talker feature from a voice of the user that has been input, and calculating a voice authentication score by comparing the extracted talker feature with a talker feature stored in advance; and an authentication integration unit for outputting an authentication integration result calculated based on the ear authentication score and the voice authentication score. After the sound is output into the ear, a recording unit inputs the voice of the user.
