BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18483881 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 reproduces a sound.
- An ear authentication unit captures the reverberation sound of the reproduced sound in the user's ear and extracts an ear acoustic feature from it.
- The ear authentication unit compares the extracted ear acoustic feature 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 calculates a voice authentication score by comparing it with a stored talker feature.
- 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 doors or accessing sensitive information, by verifying the user's identity through ear and voice authentication.
- Financial transactions: The technology can be implemented in banking or payment systems to ensure secure and accurate identification of users during transactions.
- Mobile devices: The device can be integrated into smartphones or tablets for user authentication, providing an additional layer of security for device access and data protection.
Problems solved by this technology:
- Enhanced security: By combining ear and voice authentication, the device offers a more robust and reliable method for verifying the user's identity, reducing the risk of unauthorized access or identity theft.
- Anti-spoofing measures: The use of both ear and voice authentication helps prevent spoofing attempts, as it becomes more challenging for an imposter to replicate both the ear acoustic feature and the talker feature of the authorized user.
Benefits of this technology:
- Improved user experience: The device offers a seamless and convenient authentication process by utilizing the user's natural ear and voice characteristics, eliminating the need for additional physical tokens or passwords.
- Accurate and reliable identification: 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.
- Increased security: By incorporating multiple biometric factors, the device enhances the overall security of authentication systems, making it more difficult for unauthorized individuals to gain access.
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.
