Problems solved by technology

At present, a special imitation fingerprint film technology has appeared on the market. By copying the subject's fingerprint pattern, the fingerprint can be copied on a similar silica gel material. Because the copied fingerprint is the same as the subject's fingerprint, a conventional fingerprint identification device can also be obtained. The verification is passed, which makes the security of identity verification originally intended to use the uniqueness of human fingerprints unguaranteed

Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustr...

Abstract

The invention relates to a fingerprint detection device, and the device comprises a circuit board, a processor, a fingerprint sensing chip, and a living body recognition assembly. The fingerprint sensing chip is used for collecting a fingerprint image of a finger of a to-be-verified person, and can enable the fingerprint image to be transmitted to the processor. The living body recognition assembly comprises a light source module and a light-sensing detector, wherein the light source module is electrically connected with the circuit board and can emit an optical signal. The light-sensing detector is electrically connected with the circuit board, can receive an optical signal reflected by a finger of the to-be-verified person, and enables the optical signal reflected by the finger to be transmitted to the processor. The processor can enable the optical signal reflected by the finger to be converted into a pulse signal, can determine whether the fingerprint sensing chip is started or not according to the pulse signal, and also can determine the identity of the to-be-verified person according to the fingerprint image. The above device can achieve the recognition of the fingerprint of a living body, and enables identity verification to be safer and more reliable.

Description

Technical field [0001] The invention relates to the field of touch screens, and in particular to a fingerprint detection device. Background technique [0002] The conventional fingerprint identification device in the prior art only recognizes the fingerprint pattern to be tested, compares it with the fingerprint pattern recorded in the system, and if the judgment is consistent, it is judged that the fingerprint pattern has passed the verification. At present, a special imitation fingerprint film technology has appeared on the market. By copying the fingerprint pattern of the subject, fingerprints can be copied on similar silicone materials. Since the copied fingerprint is the same as the fingerprint of the subject, a conventional fingerprint identification device can also be obtained. The verification is passed, which makes the security of identity verification using the uniqueness of human fingerprints not guaranteed. Summary of the invention [0003] Based on this, it is necess...
