Problems solved by technology

Now there is a special imitation fingerprint film technology 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, the same can also be obtained from the conventional fingerprint recognition device. The verification is passed, which makes the original plan to use the unique characteristics of human fingerprints for identity verification security not guaranteed

Embodiment Construction

[0025] 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.

[0026] 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 apparatus. The fingerprint detection apparatus comprises a circuit board, a processor, a conductive substrate, a fingerprint sensing chip and an in-vivo identification assembly. The fingerprint sensing chip is installed on the conductive substrate and is electrically connected with the conductive substrate. The fingerprint sensing chip is used for acquiring fingerprint patterns of fingers of a person to be verified and transmitting the fingerprint patterns to the processor. The in-vivo identification assembly comprises a light source module and a photodetector, wherein the light source module can emit optical signals, and the photodetector can receive the optical signals reflected by the fingers of the person to be verified and can transmit the optical signals reflected by the fingers to the processor. The processor can convert the optical signals reflected by the fingers into pulse signals, can determine whether to start the fingerprint sensing chip according to the pulse signals and can also determine the identity of the person to be verified according to the fingerprint patterns. The fingerprint detection apparatus can be used for detecting in-vivo fingerprints and enables fingerprint identity verification to be more secure and reliable.

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, and compares it with the fingerprint pattern recorded in the system. If the judgment is consistent, it is determined that the fingerprint pattern has passed the verification. Now there is a special imitation fingerprint film technology 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, the same can also be obtained from the conventional fingerprint recognition device. The verification is passed, which makes the security of identity verification originally intended to use the uniqueness of human fingerprints unguaranteed. Contents of the invention [0003] Bas...
