Biometrics authentication device and method

A biometrics authentication device, comprising:

• an object scanner, receiving at least one of object images of a living being;
• an object authentication device, electrically connected to the object scanner, performing an object authentication according to the at least one object image;
• a pulse waveform generation device, receiving the object images to generate a pulse waveform of the living being according to the object images and timestamps at which the object images are captured;
• a pulse waveform authentication device, electrically connected to the pulse waveform generation device, performing a pulse waveform authentication device according to the pulse waveform;
• and
• a determination device, electrically connected to the object authentication device and the pulse waveform authentication device, determining a biometrics authentication result according to results of the object waveform authentication and the pulse waveform authentication.
