BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18483896 titled 'BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM
Simplified Explanation
The patent application describes a biometric authentication device that combines ear and voice authentication to verify the identity of a user. Here are the key points:
- The device includes a replay unit that reproduces a sound.
- An ear authentication unit captures the reverberation sound of the reproduced sound in the user's ear.
- The ear authentication unit 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 captures the user's voice 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 or accessing sensitive information.
- Identity verification: It can be used in various industries where identity verification is crucial, such as banking, healthcare, and law enforcement.
Problems solved by this technology:
- Enhanced security: By combining ear and voice authentication, the device provides a more robust and reliable method for verifying the identity of a user.
- Protection against spoofing: The use of both ear and voice authentication features makes it difficult for impostors to mimic or spoof the user's identity.
Benefits of this technology:
- Improved accuracy: The combination of ear and voice authentication increases the accuracy of the authentication process, reducing the chances of false positives or false negatives.
- User convenience: The device captures the user's voice after the sound is output into the ear, eliminating the need for separate voice input, making the authentication process more convenient for the user.
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.
