Problems solved by technology

[0004] The current fingerprint identification system can obtain high false rejection rate (FAR) and false recognition rate (FRR) in a small volume, but the image collected for identification is located on the surface of the finger skin, which is easy to be copied and cannot be verified. It is the fingerprint of the living body itself, so the security is not high

Embodiment Construction

[0038] As described in the background, the existing optical fingerprint recognition system can obtain high false rejection rate (FAR) and false recognition rate (FRR) in a small volume, but the image collected for identification is located on the surface of the finger skin. It is easy to be copied, and it cannot be verified whether it is the fingerprint of the living body itself, so the security is not high.

[0039] To this end, the present invention provides a fingerprint recognition device and a detection method thereof, the fingerprint recognition device includes a first light source for emitting a first outgoing light, and the first outgoing light penetrates a finger to form a first detection light; The second light source is used to emit the second outgoing light, and the second outgoing light is reflected on the surface of the finger to form the second detection light; the sensor is used to receive the first detection light and the second detection light, and detect the ...

Abstract

The invention relates to a fingerprint identification device and a fingerprint identification system. The fingerprint identification device includes a first light source, a second light source and a sensor; the first light source is used for emitting first emergent light, wherein the first emergent light is transmitted through a finger to form first detection light; the second light is used for emitting second emergent light, wherein the second emergent light is reflected at the surface of the finger so as to form second detection light; and the sensor is used for receiving the first detection light so as to carry living body judgment and is also used for receiving the second detection light so as to carry out fingerprint identification. The fingerprint identification device can not only carry out fingerprint recognition, but also can carry out living body judgment, and therefore, with the fingerprint identification device adopted, whether an object arranged on the sensor is a living body can be identified, and security can be improved with the FAR (false accept rate) and FRR (false rejection rate) of fingerprint detection ensured.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a fingerprint identification device and a fingerprint identification system. Background technique [0002] Fingerprint recognition technology is to collect the fingerprint image of the human body through the fingerprint sensor, and then compare it with the existing fingerprint imaging information in the system to judge whether it is correct or not, and then realize the technology of identity recognition. Due to its ease of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, such as security inspection fields such as public security bureaus and customs, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] The optical fingerprint imaging system is a system that uses the principle of light refraction and reflection to collect fingerprints. Such as figure...
