Embodiment 1

[0027] According to an embodiment of the present invention, a fingerprint verification method is provided. Such as figure 1 Shown is a flow chart of the fingerprint verification method according to the first embodiment of the present invention.

[0028] Step S110, setting multiple fingerprint collection tracks.

[0029] The user interface of the terminal can display multiple set fingerprint collection tracks. The user inputs fingerprints of multiple fingers according to multiple fingerprint collection tracks, and moves continuously on the fingerprint collection tracks in parallel.

[0030] When setting fingerprint collection tracks, multiple tracks designed or downloaded by the user can be set as multiple fingerprint collection tracks; or, multiple fingerprint collection tracks can be set according to a pre-generated fingerprint motion model. in,

[0031] The fingerprint motion model includes: a plurality of fingerprint collection tracks, a three-dimensional fingerprint co...

Embodiment 2

[0051] The following further explains how to set multiple fingerprint collection trajectories according to the pre-generated fingerprint motion model. Such as figure 2 Shown is a flow chart of the fingerprint verification method according to the second embodiment of the present invention.

[0052] Step S210, setting multiple fingerprint collection trajectories for generating a fingerprint motion model.

[0053] The setting of multiple fingerprint collection trajectories is not the setting of multiple fingerprint collection trajectories in step S110. In this step, multiple fingerprint collection trajectories are set in order to generate a fingerprint motion module.

[0054] The multiple fingerprint collection trajectories conform to the ergonomic design, that is, the user's fingers can easily draw the multiple fingerprint collection trajectories. Therefore, when setting fingerprint collection tracks, it is necessary to set corresponding three-dimensional fingerprints for ea...

Embodiment 3

[0070] The fingerprint motion model can also be generated after the fingerprint collection trajectory is set and before the matching verification. This embodiment will further illustrate this method. Such as Figure 4 Shown is a flow chart of the fingerprint verification method according to the third embodiment of the present invention.

[0071] Step S410, setting multiple fingerprint collection tracks.

[0072] Setting multiple fingerprint collection tracks in this step is equivalent to setting multiple fingerprint collection tracks in step S110.

[0073] According to the multiple tracks designed and downloaded by the user, multiple fingerprint collection tracks are set in the user interface.

[0074] Users can design or download multiple tracks according to their own interests to increase the fun of fingerprint verification. Users can also design or download trajectories that other users cannot imitate according to the characteristics of their own fingers, increasing the ...

Abstract

The invention discloses a fingerprint verification method and apparatus. The method comprises the steps of setting a plurality of fingerprint acquisition trajectories; detecting a fingerprint that moves simultaneously on the plurality of fingerprint acquisition trajectories; acquiring fingerprint motion information on the plurality of fingerprint acquisition trajectories; performing matching verification processing on the fingerprint motion information to determine whether a fingerprint motion model exists which matches the fingerprint motion information, if so, passing the verification, and otherwise, failing to pass the verification. The invention realizes dynamic multi-fingerprint verification of a user, that is, the trajectories of continuous movement of the fingerprint and the change in the fingerprint on each trajectory are verified. The invention can effectively improve the accuracy of fingerprint verification and enhance the information security.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fingerprint verification method and device. Background technique [0002] Most of the existing fingerprint verification is static fingerprint verification, and what is verified is the user's two-dimensional fingerprint, that is, the static two-dimensional fingerprint model is stored in the terminal first; then the user inputs his own fingerprint on the fingerprint collection device provided by the terminal; The terminal collects the fingerprint input by the user and compares it with the fingerprint model in the terminal to identify whether the input fingerprint and the fingerprint model are the same. If they are the same, the verification passes; if they are different, the verification fails. [0003] Because static two-dimensional fingerprints are very easy to leak in life, illegal users can copy and use the user's fingerprints to achieve their own illegal purposes, caus...
