Embodiment approach

[0149] As an optional implementation, the second acquisition unit includes:

[0150] (1) a first acquisition module, configured to acquire a plurality of second sample fingerprint sub-images from the sample fingerprint image;

[0151] (2) A first determination module, configured to determine each of the plurality of original fingerprint images as a current fingerprint image, and perform the following steps until traversing the plurality of original fingerprint images: calculating the The similarity between the current fingerprint image and each of the second sample fingerprint sub-images; determining the second sample fingerprint sub-image whose similarity is greater than the first threshold as the target image of the current fingerprint image ;

[0152] (3) A statistical module, configured to count the number of the target images corresponding to each original fingerprint image after the traversal is completed.

[0153] Through this embodiment, through the above method, the...

Abstract

The invention discloses a universal fingerprint generation method and device based on artificial intelligence and a cloud server, a storage medium and an electronic device. The method comprises the following steps: obtaining a plurality of original fingerprint images output by a target fingerprint generation model, wherein the target fingerprint generation model is a model obtained by training anoriginal generative adversarial network by using a target sample fingerprint sub-image, the target fingerprint generation model is used for outputting a plurality of original fingerprint images afterinputting random data, the target sample fingerprint sub-image is an image screened from a plurality of first sample fingerprint sub-images and used for training an original generative adversarial network, and the first sample fingerprint sub-image is an image intercepted from the sample fingerprint image; obtaining a target image corresponding to each original fingerprint image in the plurality of original fingerprint images; selecting a target fingerprint image from the plurality of original fingerprint images; and determining a fingerprint indicated by the target fingerprint image as a universal fingerprint. The technical problem of low universal fingerprint generation accuracy is solved.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a method and device for generating universal fingerprints based on artificial intelligence and cloud servers, a storage medium and an electronic device. Background technique [0002] In the prior art, in some cases, it is necessary to generate a universal fingerprint, such as using the universal fingerprint to test the security of a fingerprint unlocking system of a terminal. Universal fingerprint, also known as MasterPrints, is an artificially constructed fingerprint image. Using this fingerprint image for fingerprint authentication will result in a higher FMR than random natural fingerprints. FMR (False Match Rate): False match rate, that is, the probability of taking a fingerprint that should not match as a matching fingerprint. [0003] In the prior art, in the process of generating universal fingerprints, fingerprints are usually randomly cut out from a finge...
