PERSONAL AUTHENTICATION DEVICE BASED ON ECHO SOUNDS, PERSONAL AUTHENTICATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18611775 titled 'PERSONAL AUTHENTICATION DEVICE BASED ON ECHO SOUNDS, PERSONAL AUTHENTICATION METHOD, AND RECORDING MEDIUM
Simplified Explanation: The personal authentication device described in the patent application uses acoustic signals to identify and authenticate users without causing them significant psychological or physical burden.
- **Key Features and Innovation:**
* Transmission unit sends a first acoustic signal to the user's head. * Observation unit detects a second acoustic signal after the first signal is transmitted. * Calculation unit analyzes acoustic characteristics from the first and second signals. * Extraction unit identifies user-related features from the acoustic characteristics. * Storage control unit registers the feature amount in the storage unit. * Identification unit verifies the user by comparing feature amounts. * Storage unit stores the first feature amount for future identification.
- **Potential Applications:**
The technology can be used for secure access control, user authentication in various systems, and biometric identification.
- **Problems Solved:**
The device simplifies the authentication process for users, reducing the need for complex passwords or physical tokens.
- **Benefits:**
Users experience a more convenient and user-friendly authentication process, enhancing security while minimizing user burden.
- **Commercial Applications:**
"Acoustic Authentication Device for Simplified User Security" can be marketed to companies looking to enhance their security systems with user-friendly authentication methods.
- **Prior Art:**
Readers interested in prior art related to acoustic authentication devices can explore research on biometric authentication systems and acoustic signal processing technologies.
- **Frequently Updated Research:**
Stay informed about advancements in biometric authentication, acoustic signal processing, and user-friendly security technologies to understand the latest developments in the field.

Original Abstract Submitted
Provided is a personal authentication device capable of simply securing security with little psychological and physical burden of a user to be authenticated. Personal authentication device includes: transmission unit that transmits a first acoustic signal to a user's head; observation unit that observes a second acoustic signal after the first acoustic signal propagation; calculation unit that calculates acoustic characteristics from the first and the second acoustic signal; extraction unit that extracts a feature amount related to a user from the acoustic characteristics; storage control unit that registers the feature amount in the storage unit; identification unit that identifies the user by collating the first feature amount with a second feature amount; and storage unit stores the first feature amount, wherein while identification unit identifies the user as being identical, transmission unit transmits the first acoustic signal every predetermined interval.
