Embodiment Construction

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0066] The invention provides a fingerprint authentication method, such as figure 1 shown, including:

[0067] Step 101, obtaining detected N fingerprint information, wherein N is greater than or equal to 2;

[0068] Step 102, look up N comparison fingerprint information corresponding to each fingerprint information from the fingerprint database, and the comparison fingerprint information is a regional fingerprint;

[0069] Step 103, if ...

Abstract

The invention discloses a fingerprint authentication method and device, and relates to the technical field of biological recognition. The fingerprint authentication method comprises the steps of acquiring N pieces of detected fingerprint information, wherein N is greater than or equal to 2; finding comparison fingerprint information corresponding to each piece of fingerprint information in a fingerprint database, wherein the comparison fingerprint information is a regional fingerprint; and determining the N piece of fingerprint information to pass the authentication if the N pieces of comparison fingerprint information are determined to be matched with a preset fingerprint input mode, wherein the preset fingerprint input mode is a mode that input is required to be performed according to N pieces of preset regional fingerprint information. In the embodiment of the invention, N pieces of preset regional fingerprint information required to be inputted are compared rather than the whole fingerprint information, so that the preset fingerprint input mode is not acquired even if fingerprint information of a user is stolen, and fingerprint authentication cannot be passed, so that the security of fingerprint recognition is improved.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to a fingerprint authentication method and device. Background technique [0002] Fingerprint characteristics are one of the characteristics that do not change throughout a person's life, and the possibility that different people's fingerprint characteristics are the same is almost zero. Human fingerprints contain natural password information, which must have universality, uniqueness, and lifetime invariance as password information. Therefore, fingerprint recognition technology, as a reliable biometric technology, has received people's attention. [0003] In recent years, fingerprint recognition technology has been more and more widely used as a biometric-based identity authentication technology. Such as: smart phones, access control, e-commerce, attendance systems, automatic teller machines (ATM, Automatic Teller Machine) and criminal identification systems, etc....
