BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18483905 titled 'BIOMETRIC AUTHENTICATION DEVICE, BIOMETRIC AUTHENTICATION METHOD, AND RECORDING MEDIUM
Simplified Explanation
The abstract describes a biometric authentication device that combines ear and voice authentication to verify the identity of a user.
- The device includes a replay unit that reproduces a sound.
- An ear authentication unit captures the reverberation sound of the sound in the user's ear, extracts an ear acoustic feature from it, and calculates an ear authentication score by comparing it with a stored ear acoustic feature.
- 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 output an authentication integration result.
Potential applications of this technology:
- Biometric security systems: The device can be used in various security systems that require strong authentication, such as access control systems, secure facilities, and financial transactions.
- Personal devices: The technology can be integrated into smartphones, tablets, or laptops to provide secure user authentication for unlocking devices, accessing sensitive information, or making secure transactions.
Problems solved by this technology:
- Enhanced security: By combining ear and voice authentication, the device provides a more robust and reliable authentication method compared to traditional methods like passwords or PINs.
- Anti-spoofing: The use of ear and voice authentication helps prevent spoofing attempts by impostors, as both features are unique to each individual.
Benefits of this technology:
- Improved user experience: The device offers a convenient and user-friendly authentication method that does not require physical contact or complex passwords.
- Higher security: The combination of ear and voice authentication provides a higher level of security, 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.
