Detailed Description

The present application provides a screen unlocking method, a screen unlocking device, a screen unlocking storage medium, and a mobile terminal, and in order to make the purpose, technical solution, and technical effect of the present application more clear and clear, the following further detailed description of the present application should be understood that the specific embodiments described herein are only used for explaining the present application, and are not used to limit the present application.

Referring to fig. 1, fig. 1 is a schematic flow chart of a screen unlocking method provided in an embodiment of the present application, which is applied to a mobile terminal, and a specific flow of the screen unlocking method may be as follows:

s101: and receiving a screen unlocking instruction when the display screen is in a locked state.

The mobile terminal comprises a display screen, and in order to ensure the security of information stored in the mobile terminal, the mobile terminal may lock the display screen of the mobile terminal when receiving a screen locking instruction, and in order to ensure that a user of the mobile terminal can normally acquire the information stored in the mobile terminal, after the mobile terminal locks the display screen, the mobile terminal may unlock the display screen when receiving a screen unlocking instruction, that is, the operating state of the display screen includes a locked state and an unlocked state.

It should be noted that the screen locking instruction is used to instruct the mobile terminal to lock the display screen, and the screen locking instruction may be triggered and obtained by a user through executing a preset operation. The screen unlocking instruction is used for indicating the mobile terminal to unlock the display screen, and the screen unlocking instruction can be triggered and acquired by a user through executing preset operation. The preset operation may be a click operation, a slide operation, a touch operation, a key operation, or the like, and in practical application, the preset operation may also be another operation.

S102: and determining the target number of the target touch blocks and the display position of each target touch block according to the screen unlocking instruction.

In an embodiment, to determine the target number of target touch blocks, the step S102 may specifically include:

and S1021, acquiring the historical number of the target touch blocks.

The history number may refer to a target number determined when the mobile terminal is triggered to unlock the screen last time.

S1022, determining the target number of the target touch blocks from a preset number library according to the historical number.

The preset number library may include a plurality of preset numbers, for example, 1, 3, 5, 6, 9, and the preset number library may specifically be a preset number sequence, where each preset number may correspond to a sequence number, and the sequence number may be obtained by sorting the plurality of preset numbers in the preset number library according to a preset rule (for example, a size order).

Specifically, after acquiring the historical number of the target touch blocks, the mobile terminal may use a preset number, in the preset number sequence, of which the sequence number is one bit after the historical number of the sequence number as the target number of the target touch blocks when the unlocking screen is triggered this time. In addition, during specific implementation, the preset number with the minimum sequence number in the preset number sequence can be preset to be one bit behind the preset number with the maximum sequence number, so that the target number of the target touch block can be circularly switched in the preset number sequence when the mobile terminal is triggered to unlock the screen each time, and further, a variable unlocking interface can be provided, and the interestingness of screen unlocking is improved.

In some alternative embodiments, the mobile terminal may further randomly select an integer from a preset value range (e.g., 1 to 10) to obtain the target number of the target touch pieces.

In a specific embodiment, before the step S102, the method may further include:

step A: and when the display screen is in an unlocking state, receiving an unlocking setting instruction.

And B: and displaying an unlocking setting interface on the display screen according to the unlocking setting instruction.

And C: and acquiring a plurality of setting schemes input by a user through an unlocking setting interface, wherein each setting scheme comprises at least one target touch block and a display position of each target touch block.

Wherein, different setting schemes can have different numbers of target touch blocks, and the display position of each target touch block in the setting scheme can be set by the user according to the use habit and preference of the user.

Specifically, when a user needs to input a new setting scheme or modify an input setting scheme, the mobile terminal may be triggered to generate an unlocking setting instruction through operations such as pressing a key, touching, clicking, and the like, so that the mobile terminal can enter an unlocking setting interface. And the user can input a plurality of setting schemes on the unlocking setting interface in a touch screen mode. For example, when a user inputs a certain setting scheme on the unlock setting interface, at least one graph (for example, a rectangle) may be drawn on the unlock setting interface by clicking with a single hand to obtain at least one target touch block included in the setting scheme, where one graph is one target touch block, and then, the user may adjust a display position of a corresponding target touch block on the unlock setting interface by clicking and dragging each target touch block.

Further, in order to determine the display position of each target touch block, the step S102 may specifically include:

and S1023, determining a target setting scheme from a plurality of setting schemes according to the target number.

Specifically, the mobile terminal may use a setting scheme including a target number of target touch blocks among the plurality of setting schemes as the target setting scheme. For example, if the number of targets is 3, the target setting scheme would also include three target touch blocks.

And S1024, determining the display position of each target touch block according to the target setting scheme.

Specifically, when the target touch block is a geometric polygon, the display position of the target touch block may include coordinates of each vertex point of the target touch block, for example, the target touch block is a rectangle, and the display position of the target touch block may include coordinates of 4 vertex points of the rectangle of the target touch block. In some embodiments, the target touch block may be an icon, and accordingly, the display position may be coordinates of a center point of the target touch block icon.

S103: and generating an unlocking interface according to the display position, wherein the unlocking interface comprises target touch blocks with the target number.

Specifically, the mobile terminal may add a corresponding target touch block at a display position of a preset background picture to obtain the unlocking interface, and the preset background picture may be preset by a user or default by a system. For example, as shown in (1) and (2) of fig. 2, the above-described unlocking interface 20 may include 2 target touch blocks 21/22.

S104: and displaying an unlocking interface on the display screen so that the user can unlock the display screen through the unlocking interface.

Specifically, the target touch blocks of the target number in the unlocking interface are used for forming a screen unlocking pattern, and the screen unlocking pattern is used for guiding a user to perform correct unlocking operation on the unlocking interface so as to unlock the display screen.

In this embodiment, since the number of the targets and the display positions of the target touch blocks determined each time the mobile terminal is triggered to unlock the screen are variable, the corresponding unlocking interface and the correct unlocking operation are also variable, so that the problem of user privacy disclosure caused by the fact that the correct unlocking operation is fixed can be avoided.

In a specific embodiment, as shown in fig. 3, after the step S104, the method may further include:

and S105, when the fact that the user performs touch operation on the unlocking interface is detected, acquiring a contact point track corresponding to the touch operation.

Specifically, the touch point trajectory may be composed of a plurality of touch points, and the plurality of touch points may be a plurality of touch points of the user on the unlocking interface recorded by the mobile terminal in sequence according to a time sequence when the user performs a touch operation on the unlocking interface. The touch operation may be a sliding type touch operation, for example, a touch sliding, and one touch operation corresponds to one touch point track, for example, when a user performs a touch sliding on the unlocking interface, if a finger of the user leaves the unlocking interface, it may be considered that the user has finished the touch operation.

And S106, unlocking the display screen according to the contact track and the display position.

As shown in fig. 3, the S106 may specifically include:

s1061, determining a contact corresponding to each vertex point from the contact track according to the display position to obtain a contact combination, wherein each contact combination corresponds to one vertex point.

Specifically, the target touch block may be a geometric figure (e.g., a geometric polygon such as a triangle, a square, a rectangle, a regular pentagon, etc.), and has at least one vertex point, and accordingly, the display position of the target touch block may include an abscissa and an ordinate of each vertex point of the target touch block, and the S1061 may specifically include: and grouping the contacts in the contact tracks, wherein the abscissa of the contact tracks is the same as the abscissa of the vertex point or the ordinate of the contact tracks is the same as the ordinate of the vertex point, so as to obtain a corresponding contact combination.

For example, as shown in (1) of fig. 2, the unlocking interface 20 includes 2 rectangular target touch blocks 21/22 thereon, wherein the target touch block 21 has four vertex points a/B/C/D, and the target touch block 22 has four vertex points E/F/G/H. The contact point trace L1 is input by the user in the form of a touch screen when the user unlocks the display screen through the unlocking interface 20. The contact trace L1 includes two contacts a/B having the same abscissa as the abscissa of the vertex point a, and two contacts C/D having the same ordinate as the ordinate of the vertex point a, i.e., the contact combination corresponding to the vertex point a is { contact a, contact B, contact C, contact D }, and so on, and the contact combinations corresponding to the vertex points B/C/D/E/F/G/H are { contact E, contact F, contact C, contact D }, { contact a, contact B, contact G, contact H }, { contact E, contact F, contact G, contact H }, { contact i, contact j, contact k, contact L, contact q }, { contact m, contact n, contact k, contact L, contact r }, { contact i, contact j, contact o, contact p, contact q } and { contact m, contact n, contact o, contact p, contact r }.

It can be understood that, for the same vertex point, if there is neither a contact point whose abscissa is the same as the abscissa of the vertex point nor a contact point whose ordinate is the same as the ordinate of the vertex point in the contact point trajectory, it may be considered that the contact point combination corresponding to the vertex point is empty, that is, there is no contact point.

S1062, judging whether four contacts exist in each contact combination and whether an area defined by the four contacts contains a corresponding vertex point, if so, executing S1063, and if not, not processing.

Specifically, for the same vertex angle point, when the contact combination corresponding to the vertex angle point includes at least one contact having the same abscissa as the abscissa of the vertex angle point and having the ordinate greater than the ordinate of the vertex angle point, at least one contact having the same abscissa as the abscissa of the vertex angle point and having the ordinate less than the ordinate of the vertex angle point, at least one contact having the same ordinate as the ordinate of the vertex angle point and having the abscissa less than the abscissa of the vertex angle point, and at least one contact having the same ordinate as the ordinate of the vertex angle point and having the abscissa greater than the abscissa of the vertex angle point, it may be determined that four contacts exist in the contact combination corresponding to the vertex angle point, and an area surrounded by the four contacts includes the vertex angle point. For example, as shown in (1) of fig. 2, for the vertex point a, since there are simultaneously one touch point a having the same abscissa as the abscissa of the vertex point a and having the ordinate greater than the ordinate of the vertex point a, one touch point b having the same abscissa as the abscissa of the vertex point a and having the ordinate less than the ordinate of the vertex point a, one touch point c having the same ordinate as the ordinate of the vertex point a and having the abscissa less than the abscissa of the vertex point a, and one touch point d having the same ordinate as the ordinate of the vertex point a and having the abscissa greater than the abscissa of the vertex point a, in the touch point combination { touch point a, touch point b, touch point c, touch point d } corresponding to the vertex point a, four touch points a/b/c/d are present, and the area abcd enclosed by the four contacts a/b/c/d contains the vertex point a.

And if each vertex point in all the vertex points can meet the condition that four touch points exist in the corresponding touch point combination, and the area enclosed by the four touch points contains the vertex point, executing the subsequent step S1063 to unlock the display screen, otherwise, continuing to lock the display screen.

For example, as shown in fig. 3, since each of the vertex points a/B/C/D/E/F/G/H in all the vertex points a/B/C/D/E/F/G/H on the unlocking interface 20 satisfies that there are four contact points in the corresponding contact point combination, and the area enclosed by the four contact points includes the vertex point, the mobile terminal may then perform the following step S1063.

For another example, as shown in (2) of fig. 2, when a user inputs a contact trace L2 on a touch screen when unlocking the display screen through the unlocking interface 20, the contact trace L2 includes a contact a ' having an abscissa identical to the abscissa of the vertex point a, and includes two contacts C '/D ' having an ordinate identical to the ordinate of the vertex point a, that is, the contact combinations corresponding to the vertex point a are { contact a ', contact C ', contact D ' }, and so on, and the contact combinations corresponding to the vertex points B/C/D/E/F/G/H are { contact E ', contact C ', contact D ' }, { contact a ', contact G ', contact H ' }, { contact E ', contact H ' }, { contact k ', contact L ' }, { contact L ' }, { contact o ', contact p' } and { contact o ', contact p' }. In this case, since each vertex point a/B/C/D/E/F/G/H in all vertex points a/B/C/D/E/F/G/H on the unlocking interface 20 does not satisfy that there are four contact points in the corresponding contact point combination, and the area enclosed by the four contact points includes the vertex point, the mobile terminal will not perform the subsequent step S1063, but will continue to maintain the lock on the display screen.

In an embodiment, in order to increase the complexity of a contact track input by a user when the user correctly unlocks, so that the unlocking manner of the touch screen is not easily grasped by other people, the S1062 may specifically include: and judging whether four contacts exist in each contact combination, wherein an area formed by the four contacts is a square area or a rectangular area and comprises corresponding vertex points, if so, executing S1063, and if not, not processing.

Specifically, for the same vertex angle point, when the contact combination corresponding to the vertex angle point includes a contact 1 having the same abscissa as the abscissa of the vertex angle point and having the ordinate greater than the ordinate of the vertex angle point, a contact 2 having the same abscissa as the abscissa of the vertex angle point and having the ordinate less than the ordinate of the vertex angle point, a contact 3 having the same ordinate as the ordinate of the vertex angle point and having the abscissa less than the abscissa of the vertex angle point, and a contact 4 having the same ordinate as the ordinate of the vertex angle point and having the abscissa greater than the abscissa of the vertex angle point, and the four contacts 1/2/3/4 are sequentially connected in the order of contact 1-contact 3-contact 2-contact 4 and then enclose a square region, it may be determined that there are four contacts 1/2/3/4 in the contact combination corresponding to the vertex angle point, and the area enclosed by the four contact points 1/2/3/4 is a square area and contains the vertex point.

And if each vertex point in all the vertex points can meet the requirement that four touch points exist in the corresponding touch point combination, an area formed by the four touch points is a square area and contains the vertex point, the subsequent step S1063 is executed to unlock the display screen, and otherwise, the locking of the display screen is continuously maintained.

S1063, unlocking the display screen.

Different from the prior art, the screen unlocking method in the embodiment is applied to a mobile terminal which comprises a display screen, receives a screen unlocking instruction when the display screen is in a locked state, determines the target number of the target touch blocks and the display position of each target touch block according to the screen unlocking instruction, generates an unlocking interface according to the display positions, comprises the target touch blocks in the target number on the unlocking interface, and displays the unlocking interface on the display screen, so that a user can unlock the display screen through the unlocking interface, and the display positions and the number of the target touch pieces on the unlocking interface can be changed when the screen is unlocked, thereby ensuring that the input touch track is not fixed and unchanged when the screen is correctly unlocked, and avoiding the situation that the touch screen unlocking mode is fixed and is easy to master by others, thereby leading to the problem of revealing the privacy of the user.
