Abstract: An authentication system for authenticating an identification of a subject is provided. The authentication system includes a photoplethysmogram (PPG) sensor, a storage device, and a processor. The PPG sensor is configured to sense pulses of a blood vessel of the subject to generate a sensed PPG signal of the subject. The storage device stores an authentication model. The processor is configured to load the authentication model from the storage device and input the sensed PPG signal and a reference PPG signal into the authentication model to generate a result value which indicates whether the identification of the subject passes an authentication test.
