Authentication method and apparatus of biometric payment device, computer device, and storage medium

A payment authentication server, comprising:

• a memory and a processor, the memory storing a computer program, and the processor, when executing the computer program, being configured to perform:
• generating a public key corresponding to the biometric payment device, comprising:
• receiving multi-factor device information of the biometric payment device uploaded by a manufacturer device;
• generating a dynamic link library file storing a key of the biometric payment device according to the multi-factor device information;
• obfuscating and reinforcing, at the payment authentication server, a code of the dynamic link library file, to obtain a reinforced dynamic link library file;
• transmitting the reinforced dynamic link library file to the biometric payment device through the manufacturer device, the reinforced dynamic link library file being locally burned to the biometric payment device;
• and
• receiving, through the manufacturer device, a public key corresponding to the biometric payment device, wherein the public key is generated together with a private key by the biometric payment device based on the reinforced dynamic link library file;
• and
• authenticating the biometric payment device, comprising:
• receiving an authentication request transmitted by the biometric payment device based on a signature and device information, the signature being generated by the biometric payment device according to the private key and the device information;
• verifying the signature according to the device information;
• generating an authentication result of the biometric payment device according to a verification result;
• and
• returning the authentication result to the biometric payment device, to implement a biometric payment based on biometric data transmitted by the authenticated biometric payment device.

A non-transitory computer-readable storage medium, storing a computer program, the computer program, when executed by a processor of a payment authentication server, causing the processor to perform:

• generating a public key corresponding to the biometric payment device, comprising:
• receiving multi-factor device information of the biometric payment device uploaded by a manufacturer device;
• generating a dynamic link library file storing a key of the biometric payment device according to the multi-factor device information;
• obfuscating and reinforcing, at the payment authentication server, a code of the dynamic link library file, to obtain a reinforced dynamic link library file;
• transmitting the reinforced dynamic link library file to the biometric payment device through the manufacturer device, the reinforced dynamic link library file being locally burned to the biometric payment device;
• and
• receiving, through the manufacturer device, a public key corresponding to the biometric payment device, wherein the public key is generated together with a private key by the biometric payment device based on the reinforced dynamic link library file;
• and
• authenticating the biometric payment device, comprising:
• receiving an authentication request transmitted by the biometric payment device based on a signature and device information, the signature being generated by the biometric payment device according to the private key and the device information;
• verifying the signature according to the device information;
• generating an authentication result of the biometric payment device according to a verification result;
• and
• returning the authentication result to the biometric payment device, to implement a biometric payment based on biometric data transmitted by the authenticated biometric payment device.
