Problems solved by technology
Since the duplicated fingerprint film is the same as the fingerprint pattern of the tissue to be detected, the duplicated fingerprint can also pass the verification of the conventional fingerprint identification device, which brings a great hidden danger to the security of the fingerprint identification application.
[0004] In view of this, there is an urgent need to provide a new fingerprint identification technology in order to overcome the defects that existing conventional fingerprint identification devices cannot distinguish fake fingerprints, improve the accuracy of fingerprint identification, and protect the privacy and property safety of electronic equipment users.

The invention provides a fingerprint identification device, a fingerprint identification method and a terminal device. The fingerprint identification device comprises: an oxyhemoglobin data acquisition module, for acquiring oxyhemoglobin saturation data of detected tissues; a temperature data acquisition module, for acquiring temperature data of the detected tissues; a fingerprint identification module, for acquiring fingerprint data of the detected tissues; a transmission module, which is coupled with the fingerprint identification module; and a processing module, which is coupled with the oxyhemoglobin data acquisition module, the temperature data acquisition module and the transmission module and is used to analyze the oxyhemoglobin saturation data and the temperature data, judge whether the oxyhemoglobin saturation data and the temperature data are within the preset range, and control the transmission module to transmit the fingerprint data of the detected tissues to a fingerprint database for fingerprint identification when both the oxyhemoglobin saturation data and the temperature data are within the preset range. The invention can prevent the potential safety hazards of the prior art of identify recognition with a fake body.
Description
technical field [0001] The present disclosure relates to the technical field of biological feature identification, and in particular to a fingerprint identification device with a living body detection function, a fingerprint identification method and a terminal device thereof. Background technique [0002] Biometric identification technology is the use of human physiological or behavioral characteristics to identify individuals. At present, the physiological characteristics that have been used for biometric identification include hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc. Among them, fingerprints are the most reliable physiological characteristics, so fingerprint recognition technology is the most widely used. [0003] The conventional fingerprint identification device in the existing fingerprint identification technology is to collect the operator's fingerprint information, and compare and identify the fingerprint image of the collected operator...
