Intelligent fingerprint identification device and device

Abstract

The invention provides an intelligent fingerprint identification device and device. The device comprises an intelligent fingerprint identification control unit, a fingerprint identification module, a physiological parameter detecting module and a power supply unit. The fingerprint identification module is used for performing conventional fingerprint identification. The physiological parameter detecting module is used for detecting the physiological parameters of a living body, wherein the physiological parameters include blood oxygen, heart rate and the like. The physiological parameter detecting module can be one or more of an optical reflective heart rate detecting module, an optical reflective blood oxygen detecting module, an optical transmission-type heart rate detecting module, an optical transmission-type blood oxygen detecting module, and an electrocardiogram type heart rate detecting module. The method includes: setting comparison data; detecting the physiological parameters; judging whether living body tissues is the tissues with pulse signals or not; identifying fingerprints; judging whether the fingerprints conform to set fingerprints or not; executing set actions. The device and the method have the advantages that heart rate or blood oxygen saturation identification is performed before conventional fingerprint identification, verification passing by using a cut-off finger or a simulated fingerprint film is avoided, and safety of the fingerprint identification device is increased.

Description

technical field [0001] The invention relates to an intelligent fingerprint identification device and a corresponding method, more specifically to a device and a corresponding method for identifying fingerprint information combined with physiological parameters, belonging to the technical field of data identification. Background technique [0002] Fingerprint identification technology is widely used in security access control, attendance assessment, examination identification, safe cabinet, U disk data encryption and other fields. Individual fingerprints vary in patterns, breakpoints and intersections, making them unique and permanent throughout life. Accordingly, by comparing a person's fingerprint with the pre-saved fingerprint data, the real identity of the person can be verified, which is fingerprint recognition technology. A fingerprint image consists of ridges with a certain width and direction (called ridges) and depressions between the ridges (called valleys). [00...

AI Technical Summary

Problems solved by technology

The conventional fingerprint recognition device in the prior art only recognizes the fingerprint pattern to be tested, and compares it with the fingerprint pattern recorded in the system. If the judgment is consistent, it is determined that the fingerprint pattern has passed the verification.
