Detailed Description
the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a fingerprint unlocking method of a mobile terminal according to a first embodiment of the present application. The application provides a fingerprint unlocking method of a mobile terminal, which comprises the following steps:
s10: the method comprises the steps of obtaining a plurality of first fingerprints, and encoding the first fingerprints to obtain a plurality of groups of first sequence groups.
Specifically, a plurality of first fingerprints stored in the mobile terminal in advance are numbered in sequence, and the numbers of the first fingerprints are different from each other. For example, the first fingerprints stored in the mobile terminal in advance are numbered sequentially from small to large, which are 1, 2, 3,. 7, 8, and 9, and the numbers of the first fingerprints are different from each other, and the number of the first fingerprint is the first sequence group.
It should be noted that the first fingerprint is a fingerprint previously entered into the mobile terminal by the user, for example: the fingerprint input when the screen locking function of the mobile terminal is used for the first time.
s20: and presetting at least one first sequence group as an unlocking sequence group.
it should be noted that one, two, or more first sequence groups may be included in the unlocking sequence group, for example, the unlocking sequence group includes numbers 8, 9, and 10, and the first fingerprints corresponding to the numbers 8, 9, and 10 are valid unlocking fingerprints.
S30: at least one second fingerprint is acquired.
Specifically, in this embodiment, when the fingerprint identification area of user's finger touch above-mentioned touch-sensitive screen, the fingerprint identification module on the touch-sensitive screen can detect the second fingerprint of user at this fingerprint identification area input. The fingerprint identification area may be a full screen display area of the touch screen, or an area capable of identifying a fingerprint, which is designated in advance in the touch screen.
S40: and judging whether the first sequence group corresponding to the at least one second fingerprint is consistent with the unlocking sequence group. If so, the process proceeds to S50.
specifically, if the mobile terminal detects that the second fingerprint is input in the fingerprint identification area of the touch screen, the mobile terminal may compare the detected input second fingerprint with a first fingerprint preset in the mobile terminal through a fingerprint identification algorithm to confirm the first sequence group corresponding to the second fingerprint. The fingerprint identification algorithm may be an algorithm for performing operations such as preprocessing, feature extraction, and matching on input fingerprint detection, and is well known to those skilled in the art and will not be described herein in detail.
after the first sequence group corresponding to the at least one second fingerprint is obtained, the first sequence group corresponding to the at least one second fingerprint is compared with a pre-stored unlocking sequence group, and if the first sequence group corresponding to the at least one second fingerprint is consistent with the pre-stored unlocking sequence group, the second fingerprint can be judged to be an effective unlocking fingerprint.
the effective unlocking fingerprint in this embodiment means that the first sequence group corresponding to the fingerprint input by the user is consistent with the pre-stored unlocking sequence group, and the input fingerprint is considered to be effective, so that operations such as unlocking a screen of the mobile terminal, unlocking an application, and paying can be performed. Otherwise, the input fingerprint is considered as a non-effective unlocking fingerprint, and the mobile terminal cannot be operated.
S50: and completing unlocking.
in this embodiment, a user enters a plurality of first fingerprints in a mobile terminal in advance, and codes the plurality of first fingerprints to obtain a plurality of groups of first sequence groups. Setting at least one first sequence group as an unlocking sequence group (i.e. at least one of the plurality of first fingerprints is a valid unlocking fingerprint). When the mobile terminal fingerprint sensor detects that the user fingerprint is input, a second fingerprint input by the user is obtained, then the mobile terminal compares the input second fingerprint with a plurality of first fingerprints input in advance, and screens out first fingerprints consistent with the input second fingerprint, so that a first sequence group corresponding to the second fingerprint is obtained. And determining whether the mobile terminal is unlocked or not by judging whether the first sequence group corresponding to the at least one second fingerprint is consistent with the unlocking sequence group or not.
Different from the situation in the prior art, in the fingerprint unlocking method of the embodiment, a plurality of first fingerprints are acquired and encoded to obtain a plurality of groups of first sequence groups, and at least one group of first sequence groups is preset as an unlocking sequence group. When a user inputs fingerprints to unlock a screen, acquiring at least one second fingerprint, and judging whether a first sequence group corresponding to the at least one second fingerprint is consistent with an unlocking sequence group; and if the two are consistent, unlocking is finished. That is to say, when the mobile terminal of the present application performs fingerprint unlocking, fingerprint verification is not directly adopted, but whether a sequence group corresponding to a fingerprint is an unlocking sequence group is verified. When the unlocking sequence groups set by the user are different, the corresponding unlocking fingerprints are also different, so that the security of the mobile terminal can be improved, a powerful barrier is added for the fingerprint use security in the prior art, and the requirement of the user on a higher encryption level is met.
Referring to fig. 2, fig. 2 is a schematic flowchart of step S10 in fig. 1. In one embodiment, step S10 includes:
s101: the plurality of first fingerprints are numbered to generate a sequence code.
specifically, the first fingerprints stored in the mobile terminal in advance are numbered in sequence, and the numbers of the first fingerprints are different from one another.
For example, there are five first fingerprints: first fingerprint 1, first fingerprint 2, first fingerprint 3, first fingerprint 4, first fingerprint 5, the serial number is as follows:
A first fingerprint 1, number 1;
A first fingerprint 2, number 2;
a first fingerprint 3, number 3;
A first fingerprint 4, number 4;
A first fingerprint 5, number 5;
the numbering is only required to be different.
s102: fingerprint features of the first fingerprint are extracted and encoded to generate a sequence segment.
Specifically, a first fingerprint of a user is acquired through a fingerprint acquisition instrument, and a skeleton diagram of the first fingerprint is obtained after preprocessing operations such as image segmentation, image filtering, image binarization, image thinning and the like are performed on the first fingerprint through a computer program, wherein the width of a line in the skeleton diagram is only one pixel. And after the fingerprint skeleton graph of the first fingerprint is obtained, extracting the fingerprint characteristics of the first fingerprint by using a fingerprint characteristic extraction algorithm.
According to the theory of fingerprint identification technology, human fingerprints can be divided into five types of arches, tent-shaped, left-dustpan-shaped, right-dustpan-shaped and bucket-shaped, as shown in fig. 12a and 12b, the arches have no central point and triangular point, the tent-shaped, the left-dustpan-shaped and the right-dustpan-shaped have a central point and a triangular point, and the bucket-shaped has two central points and two triangular points. Therefore, the fingerprint features can include four types of center points and triangle points of the fingerprint and bifurcation points and end points of fingerprint lines, and coordinate positions of the four types of points in the original fingerprint in the image can be obtained after feature extraction. And then coding the coordinate position to obtain a sequence segment with a certain length corresponding to the first fingerprint, wherein the sequence segment can be a bit string with a certain length.
Wherein the first sequence group may comprise sequence codes and/or sequence segments.

S60: and comparing the second fingerprint with the plurality of first fingerprints in sequence to determine a sequence code corresponding to the second fingerprint.
Specifically, in the process of comparing the detected input second fingerprint with the preset first fingerprint in the mobile terminal, the first fingerprint with the largest serial number may be defined, and the comparison is performed first, for example, the fingerprints 9, 8, 7, 6, and 5.
It should be understood that the embodiments of the present application are intended to cover any variations, whether small-to-large, small-to-small, or random alignments, and other simple permutations.
Referring to fig. 4, fig. 4 is a flowchart illustrating a fingerprint unlocking method of a mobile terminal according to a third embodiment of the present application. Step S40 includes:
s401: and judging whether the sequence code corresponding to the second fingerprint is consistent with the sequence code in the unlocking sequence group. If so, the process proceeds to S402.
S402: and judging whether the number of the second fingerprints is the same as that of the first fingerprints in the unlocking sequence group. If so, the process proceeds to S50.
Specifically, since the unlocking sequence group may include a plurality of first sequence groups, in order to improve security and accuracy of unlocking, it is necessary to further determine whether the number of the second fingerprints is the same as the number of the first fingerprints in the unlocking sequence group.
s50: and completing unlocking.
In this embodiment, the sequence codes in the unlocking sequence group are set as the sequence codes of the first fingerprint 1, the first fingerprint 3, and the first fingerprint 6, and if the sequence codes of the 3 second fingerprints continuously input by the user are exactly consistent with the sequence codes of the first fingerprint 1, the first fingerprint 3, and the first fingerprint 6, the unlocking is successful. I.e. the user has continuously input the second fingerprint 1 (corresponding to the sequence code of the first fingerprint 1), the second fingerprint 2 (corresponding to the sequence code of the first fingerprint 3) and the second fingerprint 3 (corresponding to the sequence code of the first fingerprint 6), the unlocking is successful.
If the number of the second fingerprints continuously input by the user is 4 or more, wherein the sequence codes of the discontinuous 3 second fingerprints are consistent with the sequence codes of the first fingerprint 1, the first fingerprint 3 and the first fingerprint 6, that is, the user continuously inputs the second fingerprint 1 (consistent with the sequence code of the first fingerprint 1), the second fingerprint 2 (inconsistent with the sequence code in the unlocking sequence group), the second fingerprint 3 (consistent with the sequence code of the first fingerprint 3) and the second fingerprint 4 (consistent with the sequence code of the first fingerprint 6), the unlocking fails.
referring to fig. 5, fig. 5 is a flowchart illustrating a fingerprint unlocking method of a mobile terminal according to a fourth embodiment of the present application. In an embodiment, after step S60, the method further includes:
S70: fingerprint features of the second fingerprint are extracted.
Specifically, a first fingerprint of a user is acquired through a fingerprint acquisition instrument, and a skeleton diagram of the first fingerprint is obtained after preprocessing operations such as image segmentation, image filtering, image binarization, image thinning and the like are performed on the first fingerprint through a computer program, wherein the width of a line in the skeleton diagram is only one pixel. And after the fingerprint skeleton graph of the first fingerprint is obtained, extracting the fingerprint characteristics of the first fingerprint by using a fingerprint characteristic extraction algorithm.
S80: and comparing the fingerprint characteristics of the second fingerprint with the fingerprint characteristics of the plurality of first fingerprints in sequence to determine the sequence segment corresponding to the second fingerprint.
Specifically, in the process of sequentially comparing the fingerprint features of the second fingerprint with the fingerprint features of the plurality of first fingerprints, the first fingerprint with the largest serial number may be defined, and the comparison is performed first, for example, the fingerprints 9, 8, 7, 6, and 5.
