Title:
FINGERPRINT IDENTIFICATION DEVICE AND FINGERPRINT IDENTIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/023729
Kind Code:
A1
Abstract:
A fingerprint identification device, comprising: an identification unit and at least one camera collection module; the camera collection module comprises: an image collection unit and a processor; the image collection unit is used to collect a pulse signal of a person to be collected (101); the processor is used to determine whether the pulse signal is a living-body pulse signal by using an imaging photoplethysmography (IPPG) technique; the identification unit is used to identify the person to be collected, if the pulse signal is a living-body pulse signal (103). In addition to the fingerprint identification device, also provided is a fingerprint identification method. By using the IPPG technique to measure the surges of blood in a human finger, a pulse signal is obtained to determine whether said finger is a living-body finger, thus improving a living-body detection rate. Moreover, the fingerprint identification device has a simple manufacturing method, and may be easily applied in industrial production.
