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 associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided 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 there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a fingerprint detection device. The fingerprint detection device includes a circuit board, a processor, a fingerprint sensing chip and a living body identification component. The fingerprint sensor chip is used to collect the fingerprint pattern of the finger of the person to be verified, and can transmit the fingerprint pattern to the processor; the living body recognition component includes a light source module and a light sensor, the light source module is electrically connected to the circuit board, and the light source module can emit light signal; the light sensor is electrically connected to the circuit board, and the light sensor can receive the light signal reflected by the finger of the person to be verified, and can transmit the light signal reflected by the finger to the processor; wherein, the processor can transmit the light signal reflected by the finger The reflected light signal is converted into a pulse signal, and the processor can determine whether to activate the fingerprint sensor chip according to the pulse signal, and the processor can also determine the identity of the person to be verified according to the fingerprint pattern. The above-mentioned fingerprint detection device can identify the fingerprint of a living body, making the fingerprint detection device more safe and reliable for identity verification.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a fingerprint detection device. Background technique [0002] The conventional fingerprint recognition 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 determined that the fingerprint pattern has passed the verification. 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 passed, which makes the security of identity verification originally intended to use the uniqueness of human fingerprints unguaranteed. Contents of the invention [0003] Based o...
