Abstract

The invention relates to a fingerprint detecting technology, and discloses a device and a method for detecting a living body fingerprint. The device for detecting the living body fingerprint comprises a fingerprint detecting unit, a living body detecting unit and a verifying unit, wherein the fingerprint detecting unit is used for detecting fingerprint information of a detected body; the living body detecting unit is used for detecting living body characteristic information of the detected body, and the living body characteristic information is unique living body information of the detected body; the verifying unit is used for comparing the detected characteristic information of the detected body with registration , which is registered in advance, information of the detected body, the verifying can be passed if the characteristic information is consistent with the registration information, and the characteristic information comprises the fingerprint information and the living body characteristic information. According to the device and the method for detecting the living body fingerprint, disclosed by the invention, compared with the prior art, as the living body fingerprint detecting device simultaneously comprises the fingerprint detecting unit and the living body detecting unit, and the unique living body characteristic information of the detected body is detected while the fingerprint information is detected, the authentication carried out through fingerprint detection can be safer and more reliable.

Description

Technical field [0001] The present invention relates to fingerprint detection technology, in particular to a live fingerprint detection device and method. Background technique [0002] At present, the biological characteristics for identifying and recognizing personal information are usually realized through physiological characteristics (for example, hair, fingerprints, blood, etc.). Among them, fingerprints are the most reliable feature. However, despite its unique characteristics, by extracting residual fingerprints, and then using materials such as gelatin, silica gel or rubber to make a fingerprint sleeve with the same pattern as the extracted fingerprint, the fingerprint sleeve is worn on the finger or fake finger. The fingerprint identification system can be fooled, which poses a great security risk to the fingerprint identification system. Summary of the invention [0003] The purpose of the present invention is to provide a living body fingerprint detection device and m...
