BIOMETRIC AUTHENTICATION SYSTEM, TEMPLATE UPDATING METHOD THEREFOR, STORAGE MEDIUM, BIOMETRIC AUTHENTICATION CLIENT DEVICE, AND BIOMETRIC AUTHENTICATION SERVER DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240104182 titled 'BIOMETRIC AUTHENTICATION SYSTEM, TEMPLATE UPDATING METHOD THEREFOR, STORAGE MEDIUM, BIOMETRIC AUTHENTICATION CLIENT DEVICE, AND BIOMETRIC AUTHENTICATION SERVER DEVICE

Simplified Explanation

The abstract describes a biometric authentication system that simplifies the process for users by generating an update value to update their biometric information without the need for re-registration.

  • Update value generation unit generates an update value
  • First update processing unit updates the template based on biometric information using the update value
  • Second update processing unit updates the verification key based on the biometric information using the update value

Potential Applications

This technology could be applied in various industries such as banking, healthcare, and government services where secure and efficient biometric authentication is required.

Problems Solved

The system eliminates the need for users to re-register their biometric information, saving time and effort for both users and administrators.

Benefits

- Improved user experience with faster and more convenient biometric authentication - Enhanced security with updated biometric templates and verification keys

Potential Commercial Applications

"Enhancing Biometric Authentication System for Improved User Experience and Security"

Possible Prior Art

There may be existing biometric authentication systems that require users to re-register their biometric information when updating their templates and verification keys.

Unanswered Questions

How does the system ensure the security of the update value during the authentication process?

The abstract does not provide details on how the update value is securely transmitted and stored to prevent unauthorized access.

Are there any limitations to the types of biometric information that can be updated using this system?

The abstract does not specify if the system is compatible with all types of biometric data, such as fingerprints, iris scans, or facial recognition.


Original Abstract Submitted

a conventional biometric authentication system has been time-consuming and labor-intensive for users since the users are requested to re-register their biometric information. according to an aspect of the present disclosure, a biometric authentication system includes an update value generation unit configured to generate an update value, a first update processing unit configured to update, using the update value, a template generated based on biometric information, and a second update processing unit configured to update, using the update value, a verification key generated along with the template based on the biometric information using the update value.
