Description
Technical field
The present invention relates to electronic technology field more particularly to a kind of terminal unlock methods and its terminal.
Background technique
In recent years quickly grow such as smart phone, plate etc., the especially smart phone of intelligent terminal are that people's life must not
The tool that can lack.User would generally include the privacy information inside the terminals such as mobile phone by way of setting sealing, commonly
Unlocking manner is that sliding trace is first arranged as password in user, need to input sliding trace again if looking on the bright side of things after screen locking and locking user, if
The sliding trace of input matches with pre-set sliding trace, then it is assumed that the terminal is that user is all, unlocks terminal, but real
The sliding trace that user inputs each time on border all may be different, if the sliding trace and pre-set sliding rail of input
Mark matching degree is higher, can unlock, if but because hand shaking or other reasons lead to sliding trace and pre-set sliding trace
Slightly lower both the i.e. trajector deviation of matching degree it is relatively a little bigger when, can not just unlock, but the terminal is really that user is all, therefore leads
Cause user experience it is bad, therefore detected by the unlocking manner terminal user whether be legitimate user testing result it is accurate
Property need to be improved.
Summary of the invention

Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
It should be appreciated that ought use in this specification and in the appended claims, term " includes " and "comprising" instruction
Described feature, entirety, step, operation, the presence of element and/or component, but be not precluded one or several other features,
Entirety, step, operation, the presence or addition of element, component and/or its set.It is also understood that in this description of the invention
Used term is merely for the sake of being not intended to limit the present invention for the purpose of describing particular embodiments.Such as in explanation of the invention
Book and it is used in the attached claims like that, other situations unless the context is clearly specified, otherwise singular
" one ", "one" and "the" are intended to include plural form.
Fig. 1 is please referred to, is a kind of schematic flow diagram for terminal unlock method that embodiment of the present invention provides, terminal unlocking
Method may operate in the terminals such as smart phone (such as Android phone, IOS mobile phone), tablet computer, the embodiment of the present invention
It is defined not to this.It should be noted that the unlocking method, which can be applied to terminal screen unlock, to be applied in terminal
The unlock of the passwords such as application program, file, the embodiment of the present invention is to this without limiting.The unlocking method includes S101~S106.
S101 receives the unlocking track that user inputs on terminal touch device.Specifically, touch device is used for for user
Carry out click or slide, and touch device can high-frequency detection go out operating position of the user on touch device.Therefore it uses
Family inputs unlocking track on touch device, and it is corresponding a series of when clicking or sliding on touch device can to obtain user
Coordinate position, and then a track is formed on touch device, which is considered as the unlocking track of user's input, it should be understood that
Unlocking track is made of several points.Preferably, touch device can be touch screen.In some possible embodiment, touch-control fills
Setting can also be Trackpad.
Received unlocking track and preset unlocking track are compared and obtain track similarity by S102.Specifically, with
When password is arranged in family, a unlocking track is had input on terminal touch device, and be stored in terminal.The unlocking track is unlock
As the unlocking track of reference when terminal.If after terminal is locked, unlock terminal needs S101 to re-enter a unlocking track, and will
It compares to obtain track similarity with the preset unlocking track as reference.It should be noted that unlocking track is wrapped
Track characteristic is included, track similarity is calculated according to the track characteristic of unlocking track, and track characteristic includes but is not limited to
The positional relationship etc. of each point in the turning of pressure, track, the direction of track, track when user's input trajectory.It should be appreciated that this
Pass through the track of the track characteristic of the unlocking track of user's input and pre-set unlocking track when comparison unlock in embodiment
Feature obtains track similarity.
S103 detects at least one current environment parameter of terminal and obtains corresponding environmental parameter value, current environment parameter
For indicating whether terminal is in legal use state.Environmental parameter includes but is not limited to unlock interval time, Xie Suowei
It sets, intensity of illumination, intensity of sound etc..Such as if environmental parameter is unlock interval time, if when this time unlock is with last unlock
Between interval time it is shorter, it is believed that terminal be unlock user it is all probability it is larger；If this time unlocked position be common position or
Person and one unlocked position of last time are close, it is also contemplated that terminal is that all probabilities of unlock user are larger；If terminal when this time unlocking
When the intensity of illumination or intensity of sound of place environment and last unlock or common unlock the intensity of illumination of environment where terminal or
Intensity of sound is close, it is also contemplated that terminal is that all probabilities of unlock user are larger.Specifically, environmental parameter can be by all kinds of
Sensor obtains.
S104, according to the environmental parameter value of detecting and its corresponding preset parameter value according to default first rule setting rail
Mark similarity threshold.Preferably, preset parameter value is a numberical range.In some embodiments, component environment parameter value institute
Corresponding preset parameter value is a numberical range N1~Nn, and preset parameter value corresponding to remaining environmental parameter value is one
Numerical value, such as N.Specifically be compared according to the environmental parameter value of detecting and its corresponding preset parameter value, and according to than
Compared with result and according to default first rule setting track similarity threshold, if detecting environmental parameter in S103 in the process,
Whether the environmental parameter value of detection detecting is consistent with corresponding preset parameter value, improves track similarity further according to testing result
Threshold value reduces track similarity threshold or the preset track similarity threshold of selection, and hereafter this will be specifically described, but
It is set when the quantity for the environmental parameter that the environmental parameter value detected in general is consistent with corresponding preset parameter value is more
Track similarity threshold be less than none environmental parameter, when value and corresponding preset parameter value are not inconsistent, set rail
Mark similarity threshold.If environmental parameter is unlock interval time and is 50 seconds in specific example, corresponding preset parameter value is
One data area is specially 0~1 minute, then assert the preset parameter value phase of the environmental parameter of detecting corresponding thereto
Symbol；If environmental parameter be unlocked position and its at a distance from one unlocked position of last time for 300 meters, if corresponding preset parameter value
For a data area, specially 0~200 meter, then the element and parameter value of the environmental parameter of detecting corresponding thereto are assert
It is not inconsistent.
S105, judge track similarity whether be more than setting track similarity threshold, if being more than, carry out S106；If not yet
It is more than then to unlock failure, terminal is still in screen lock status.
S106 unlocks terminal.
