Application: Face authentication terminal, face authentication system, and face authentication method (Patent ID: US20230421379A1)
The patent filed by Hitachi Ltd. describes a face authentication terminal that captures two face images of a person at different timings using a camera and generates biometric secret keys from these images. The terminal then creates a biometric public key based on the second secret key and sends it to an authentication server for registration. The server verifies authentication using the first secret key and the public key, completing registration upon successful verification. The system can be configured to store the key database either inside or outside the terminal, allowing for secure authentication processes.
The face authentication terminal's method involves capturing two face images of a person at different timings, generating biometric secret keys from these images, and creating a biometric public key for authentication. The terminal verifies authentication using the secret keys and public key before registering the biometric key in a database. This method ensures secure and reliable face authentication by utilizing multiple biometric factors and a verification process that involves both the terminal and an authentication server. Additionally, the system can adapt to different sensor configurations and user interactions, enhancing the overall user experience and security of the authentication process.
