Abstract

Provided is an electrocardiogram (ECG) biometric authentication system that performs biometric authentication using biometric information having unique values for each client includes one or more client terminals and a key distribution center (KDC) that uses ECG information of the one or more client terminals to issue a digital certificate. According to the configuration of the electrocardiogram biometric authentication system, security is enhanced.

Claims

1. A method for a client terminal to be issued with a certificate from a key distribution center (KDC) using an electrocardiogram (ECG), the method comprising:

collecting, by the client terminal, analog ECG waveform information in which upward pulses and downward pulses are displayed as a continuous curve;

quantizing the analog ECG waveform information so that the analog ECG waveform information has discontinuous and unique ECG information values;

binarizing the ECG information values which has become unique by the quantization to generate a binary code;

changing the binary code into a private key and encrypting the private key and a public key;

transmitting, by the client terminal, the encrypted private and public keys to a key distribution center (KDC);

decrypting the encrypted public key, in the KDC, to generate the public key by using a Rivest-Shamir-Adleman (RSA)/Elliptic Curve Cryptosystem (ECC) algorithm;

transmitting the public key to the client terminal from the KDC; and

executing authentication, by the client terminal, using the public key.

2. The method of claim 1, wherein, in decrypting the encrypted public key to generate the public key, the KDC uses the RSA/ECC algorithm to issue an ECG biometric private key verification and the certificate.
