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

The present invention relates to a manufacturing method of a fingerprint detection apparatus. The manufacturing method of the fingerprint detection apparatus comprises the following steps of: electrically connecting a fingerprint sensing chip with a circuit board, wherein the fingerprint sensing chip is used for acquiring a fingerprint pattern of a finger of a person to be verified; and respectively and electrically connecting a light source module and a photodetector with the circuit board to obtain the fingerprint detection apparatus, wherein the light source module can emit an optical signal, the photodetector can receive an optical signal reflected by the finger of the person to be verified and can transmit the optical signal reflected by the finger to a processor, the fingerprint sensing chip can transmit the fingerprint pattern to the processor, the processor can convert the optical signal reflected by the finger into a pulse signal, the processor can determine whether to start the fingerprint sensing chip according to the pulse signal and the processor also can determine the identity of the person to be verified according to the fingerprint pattern. The fingerprint detection apparatus manufactured by the method can implement fingerprint identification on the living finger, so that the fingerprint detection apparatus is safer and more reliable to carry out identity verification.
Description
technical field [0001] The invention relates to the field of touch screens, in particular to a manufacturing method of 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 i...
