Abstract:
A method and apparatus to authenticate a registered user are described. The method and apparatus include a processor configured to identify a first electrocardiogram (ECG) signal measured from the user, and determine a similarity between the first ECG signal and a second ECG signal based on the identified first ECG signal and the second ECG signal included in a reference ECG signal set. The processor is also configured to determine an authentication threshold corresponding to the reference ECG signal set, and determine whether to authenticate the first ECG signal measured from the user by comparing the determined similarity and the authentication threshold.

Claim (Index 20):
The apparatus of  claim 18 , wherein, in the case of updating the reference ECG signal set using the first ECG signal, the processor is configured to\n add the unauthenticated first ECG signal to the reference ECG signal set as the second ECG signal in response to a number of second ECG signals included in the reference ECG signal set being less than a preset number, or to add the first ECG signal to the reference ECG signal set instead of using the second ECG signal corresponding to a maximum similarity sum between the second ECG signal and other second ECG signals included in the reference ECG signal set in response to the number of second ECG signals included in the reference ECG signal set being greater than or equal to the preset number.
