Problems solved by technology

However, traditional optical or capacitive contact fingerprint collection devices, in addition to the health risks brought by contact collection, also have problems such as low collection quality, small collection area, sensitivity to dry and wet skin, and low collection consistency.
[0006] The occurrence of various public health incidents makes contact fingerprint collection equipment have a lot of health risks; while face recognition cannot be performed while wearing a mask.
And there are many inconveniences for individual users when performing biometric identification

Embodiment 1

[0173] In order to better illustrate the method proposed in the present disclosure, the method in one embodiment of the present disclosure is used in a mobile phone as an example for illustration below, and the method in this embodiment may be implemented by an application in the mobile phone. In this embodiment, fingerprint images are taken for multiple fingers of the object to be recognized, and multiple methods are used to make judgments based on the fingerprint images at the same time, that is, there are multiple judgment results, and the recognition result is obtained by combining the multiple judgment results. Specifically, in this embodiment, the fingerprint image of the identified object is first photographed, and then three judgment results are obtained according to the color fingerprint image of the identified object, the images of the identified object under different brightness conditions, and the rPPG signal of the identified object. The recognition results are obt...

Embodiment 2

[0185] In order to better illustrate the method proposed in the present disclosure, the method in one embodiment of the present disclosure is used in a non-contact acquisition device as an example for illustration. In this embodiment, the fingerprint image is taken for the finger Judgment is performed according to the fingerprint image in multiple ways, that is, there are multiple judgment results, and the recognition result is obtained by combining the multiple judgment results. Specifically, in this embodiment, the fingerprint image of the identified object is first photographed, and then based on the color fingerprint image of the identified object, images of the identified object under different light source colors, and the identified object under different light source colors and using a polarizer The image, the infrared image of the identified object, and the infrared temperature measurement results of the identified object get five judgment results, and the five judgment...

Abstract

The invention provides a non-contact fingerprint identification method and device, a terminal and a storage medium. The method comprises the following steps: a finger identification step of shooting ahand of an identification object, judging whether a finger exists in a shot picture or not, and determining the position of the finger when the finger exists; a fingerprint acquisition step of performing focusing photographing on the finger under the condition that the finger is detected in the finger identification step, and acquiring respective fingerprint images of the finger; an image transmission step of encrypting the fingerprint images of the fingers acquired in the fingerprint acquisition step, and transmitting the encrypted fingerprint images to a comparison system; a fingerprint comparison step: comparing the fingerprint image with fingerprint data in the comparison system to obtain a comparison result. According to the method disclosed in the invention, non-contact fingerprintidentification can be realized, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the field of fingerprint identification, and in particular to a non-contact fingerprint identification method, device, terminal and storage medium. Background technique [0002] With the development of artificial intelligence, identity authentication technology relying on biometrics has been widely used in recent years. Related application scenarios include face recognition, voiceprint recognition, etc. [0003] Face-based identity authentication technology is developing rapidly. Whether it is 1:N face comparison or 1:1 identity verification, there are many landing scenarios, such as integrated verification of ID card authentication, gate access, offline Pay etc. [0004] Although the advancement of artificial intelligence has made great progress in face recognition technology, and it has been popularized relatively quickly in recent years, due to the particularity of personal privacy of the face, as well as the age a...
