S101, at least one iris letter when starting destination application, in the default angular field of view of acquisition for mobile terminal
Breath.
In the embodiment of the present invention, default angular field of view can shoot maximum when image for the front camera of mobile terminal
Angular field of view, or a part of maximum angular field of view, the embodiment of the present invention are not done when the front camera shoots image
It limits.User can preset content shown on the screen for browsing to mobile terminal in angular field of view at this.
Wherein, any one or several application programs that destination application can be installed by mobile terminal, can also be with
For one or several application programs in application-specific, the embodiment of the present invention is without limitation.Such as the destination application can
Think that address list, message registration, short message, wechat, QQ, microblogging, MSN, picture library etc. are related to the application program of privacy of user, it can also be with
Refer in particular to some application program in instant messaging class application program.
In the embodiment of the present invention, when user needs to open destination application, the target application can be touched or clicked
The application icon of program after the mobile terminal detects the operation of user, just will start the destination application, and before passing through
It sets camera and acquires the image preset in angular field of view, one or more facial image is parsed from acquired image.
Thus, which can obtain out different iris informations from each facial image.Wherein, the iris information of acquisition
Quantity depends on the human eye quantity for including in collected facial image in default angular field of view.Also, it is understood that for only
When the content shown by the screen reflects (i.e. the sight of human eye is fallen on the screen) from human eye, which could know
It Chu not iris information.
In the embodiment of the present invention, since there is certain difference for everyone iris information, then not by identification
With the iris information of people, it can identify the identity of different people.Therefore, authentication is carried out by iris information to reality
It is existing it is anti-peeping be it is most suitable only.
S102, the mobile terminal judge with the presence or absence of unauthorized iris information at least one iris information, if so, holding
Row step S103；If it is not, terminating this process.
In the embodiment of the present invention, mobile terminal can be previously stored with the iris information of user, and the iris information of the user is
To authorize iris information, mobile terminal can identify the identity of user according to authorization iris information.Wherein, iris information is authorized
It can be one, be also possible to multiple, it can be the iris information of user oneself, also may include having user friend or household
Iris information, the embodiment of the present invention is without limitation.And unauthorized iris information be with authorization iris information mismatch or not
Consistent iris information, that is to say, that cannot recognize that the identity of user from unauthorized iris information.Therefore, in starting mesh
After marking application program, only iris information verification passes through, and there is no the iris letters of verification failure in default angular field of view
When breath, user could perform the next step operation to the destination application.
It therefore, will be to this extremely after acquisition for mobile terminal is at least one iris information in default angular field of view
Each iris information in a few iris information carries out authentication, is proved to be successful, that is, indicates the iris information for authorization rainbow
Film information；And verify identification, that is, indicate that the iris information is unauthorized iris information.Therefore, as long as at least one iris is believed
There are when unauthorized iris information in breath, which can just reduce the brightness value of its screen.And if this at least one
Be authorization iris information in iris information, then mobile terminal would not the present intensity value to screen make any adjustments.
Wherein, unauthorized iris information can be one, or multiple, the embodiment of the present invention is without limitation.
As a kind of feasible embodiment, which, which judges to whether there is at least one iris information, is not awarded
The concrete mode of power iris information may comprise steps of:
Step 11) judges at least one iris information with the presence or absence of the rainbow inconsistent with the default iris information of storage
Film information.
It, can be into the specific implementation, after acquisition for mobile terminal is at least one iris information in default angular field of view
Whether the default iris information of each iris information and storage that the judgement of one step is got is consistent, if unanimously, determining that this
Iris information is authorization iris information, and continues to judge next iris information until judging and default iris information
Until inconsistent iris information.
Step 12) when judge at least one iris information exist the rainbow inconsistent with the default iris information of storage
When film information, determine that there are unauthorized iris informations at least one iris information.
That is, the consistent iris information of default iris information with storage is authorization iris information, it is pre- with storage
If the inconsistent iris information of iris information is unauthorized iris information.Therefore, when mobile terminal judges at least one rainbow
When there is the iris information inconsistent with the default iris information of storage in film information, at least one iris information just can determine that
In there are unauthorized iris informations.Therefore, which can further reduce the brightness value of its screen.
The brightness value of screen is reduced to target brightness value by S103, the mobile terminal, and terminates this process.
In the embodiment of the present invention, when judging at least one iris information the shifting there are when unauthorized iris information
Dynamic terminal will obtain the brightness value of its screen, and the brightness value is decreased to target brightness value.Wherein, in target brightness value
Under, it can clearly be browsed apart from the closer user of screen (user of the mobile terminal is used) interior shown by screen
Hold, and can cannot not enough be browsed to because of screen intensity apart from screen user farther out (may be the user peeped)
Content shown by screen.
Further, which can be less than the present intensity value of screen, can also be zero, i.e. the mobile terminal
Screen blank screen is directly controlled, the embodiment of the present invention is without limitation.
In the embodiment of the present invention, the brightness value of screen is reduced to target brightness value by mobile terminal, it is possible to understand that are as follows: it will be whole
The brightness of a screen reduces；It also will be understood that are as follows: the brightness of the partial region of screen is reduced.For example, when judging this at least
There are when unauthorized iris information in one iris information, which will obtain the runnable interface institute of destination application
The content of display will just show the brightness value drop in the region of privacy information if in content including privacy information in screen
Low is target brightness value.For another example, when destination application be instant messaging in application, the mobile terminal judge exist do not award
When weighing iris information, the brightness for the chat area that instant messaging can be applied is reduced.
Optionally, which, which works as, gets at least one iris information, and judges at least one iris information
In all iris informations it is inconsistent with the default iris information of storage, then may indicate that the mobile terminal or lost,
Or it is used by unauthorized user.Therefore, which can be with lock-screen, and is grabbed and used by front camera
The image of person, sends its picture on the mobile terminal bound in advance.In this way shifting can be quickly aware of in order to user
Dynamic lost terminal, and conveniently recover.
For example, when mobile terminal starts wechat, the facial image in default angular field of view will be acquired, and from people
Iris information is obtained out in face image, it is assumed that there are three the iris informations got, then the mobile terminal just judge this three
It whether there is the iris information inconsistent with the iris information of the user of storage in a iris information.Believe if there is an iris
Cease inconsistent with the iris information of user, which will further identify the chat window of wechat, and by the chat
The brightness in the region where window reduces.
Again for example, when mobile terminal starts address list, the facial image in default angular field of view can be also acquired, and
Iris information is obtained out from facial image, it is assumed that there are two the iris informations got, then the mobile terminal just judges
It whether there is the iris information inconsistent with the iris information of the user of storage in the two iris informations.If there is a rainbow
Film information and the iris information of user are inconsistent, the mobile terminal will lock-screen, and the brightness of screen is adjusted to blank screen.
As it can be seen that in the method depicted in fig. 1, when starting destination application, mobile terminal can obtain at least one
Iris information, and judge with the presence or absence of unauthorized iris information at least one iris information, if there is unauthorized iris
The brightness value of screen is just reduced to target brightness value by information.Through the embodiment of the present invention, unauthorized iris is being detected the presence of
When information, mobile terminal can prevent from being peeped by reducing screen intensity, can prevent the information leakage of user in this way, from
And improve the safety that mobile terminal shows content.
Referring to Fig. 2, Fig. 2 is the flow diagram of another glance prevention method disclosed by the embodiments of the present invention.Wherein, scheme
Method shown in 2 can be applied to smart phone (such as Android phone, iOS mobile phone), tablet computer, palm PC and
Mobile internet device, personal digital assistant, media player, smart television, smartwatch, intelligent glasses, Intelligent bracelet etc.
Mobile terminal.As shown in Fig. 2, the glance prevention method may comprise steps of:
S201, at least one iris letter when starting destination application, in the default angular field of view of acquisition for mobile terminal
Breath.
S202, the mobile terminal judge with the presence or absence of unauthorized iris information at least one iris information, if so, holding
Row step S203；If it is not, terminating this process.
S203, the mobile terminal detect the distance between human eye and screen corresponding to each unauthorized iris information.
In the embodiment of the present invention, unauthorized iris information can be one, or multiple, the embodiment of the present invention is not done
It limits.Therefore, when mobile terminal is judged to be directed to each at least one iris information there are when unauthorized iris information
A unauthorized information detects the distance between its corresponding human eye and screen.Therefore, distance and judgement that mobile terminal detects
Unauthorized iris information out is one-to-one.
Under normal conditions, the mobile terminal detect corresponding to each unauthorized iris information between human eye and screen away from
From mode can be with are as follows: after detecting unauthorized iris information, where can determine whether human eye corresponding to the iris information
Shooting direction, can be detected corresponding to unauthorized iris information by transmitting laser or ray etc. between human eye and screen away from
From.
Specifically, the mobile terminal detects the distance between human eye corresponding to each unauthorized iris information and screen
Mode can be with are as follows: the object that user can see can form image in the pupil of eyes of user, which can pass through other
Terminal or equipment collect.Under normal circumstances, the ratio of pupil whole image is accounted in pupil image apart from the closer object of human eye
Example is larger, and smaller apart from the ratio that the farther away object of human eye accounts for pupil whole image in pupil image.Therefore, mobile terminal
It can detect its screen with a distance from human eye in the ratio of pupil image according to the mobile terminal got.
S204, the mobile terminal from the distance the smallest distance of selected value as target range.
In the embodiment of the present invention, since the sight of human eye is influenced by factors such as distance, luminous intensities.So in same brightness
In environment, for the same object, the clarity that user is seen in different distance is different；In other words in same distance
Under, for the same object, it is different that different lightness environments will lead to the clarity that user is seen.Therefore, if user just
When using mobile phone brush webpage, if human eye off screen curtain is closer, it is easier to it is clearly seen that the content shown on mobile phone, and if
Human eye off screen curtain farther out, then user will be more difficult to be clearly seen that the content shown on mobile phone.
And under normal circumstances, user is often nearest apart from the screen of mobile terminal when using mobile terminal.And its
His user can apart from screen farther out, then, if there is multiple unauthorized iris informations, mobile terminal can selected distance value
Human eye corresponding to the smallest unauthorized iris information is used as target range at a distance from screen, as long as then reducing brightness can guarantee
User cannot understand that the content shown by browsing in screen can under target range.
In the embodiment of the present invention, when mobile terminal detects human eye and screen corresponding to each unauthorized iris information
The distance between after, can be small by comparing distance value, the smallest distance of selected value is as target from the distance detected
Distance.
Further, if unauthorized iris information only one when, human eye corresponding to the unauthorized iris information
With can be used as target range at a distance from screen.
As an example it is assumed that mobile phone judge unauthorized iris information there are three when, according to mobile phone crawl these three not
It is available that entire imaging area is accounted in pupil image to mobile phone in the pupil image for authorizing human eye corresponding to iris information
Ratio, then based on experience value or special algorithm, calculate distance of the mobile phone away from human eye be respectively 60cm, 54cm and
73cm, by comparing, it is easy to which selecting distance value is the distance of 54cm as the target range for adjusting screen intensity.
It is bright that S205, the mobile terminal search target corresponding with the target range from preset distance and brightness value relationship
Angle value.
In the embodiment of the present invention, the relationship of distance and brightness value is it is to be understood that under some distance, by mobile terminal
Screen when being adjusted to a certain brightness value, most of user cannot be clearly apparent the content shown in screen just, then should be away from
In relationship with a distance from it can be stored in the brightness value with brightness value.Therefore, distance and brightness values are one-to-one.
Specifically, after mobile terminal selects target range, so that it may be found from distance and brightness value relationship
Target brightness value corresponding with target range.So when the brightness value of screen is adjusted to target brightness value by mobile terminal,
User corresponding to the nearest unauthorized iris information of screen apart from mobile terminal cannot peep in screen show in
Hold, equally it is also ensured that user itself can be relatively easy to browse to the content shown in screen.
The brightness value of screen is reduced to target brightness value by S206, the mobile terminal, and terminates this process.
As it can be seen that in the method depicted in fig. 2, mobile terminal exists in judging at least one iris information not to be awarded
When weighing iris information, the distance between human eye and screen corresponding to each unauthorized iris information can detecte out, then from this
The smallest distances of selected value are as target range in a little distances, and the screen brightness value of mobile terminal is adjusted to and target range
Corresponding target brightness value.It can guarantee that the nearest corresponding user of unauthorized iris information cannot peep screen in this way
The content of middle display, and can guarantee the corresponding user's normal use mobile terminal of authorization iris information.More humanized guarantee
The safety of information of mobile terminal promotes user experience.

Reduction unit 403 reduces the brightness of entire screen；It also will be understood that are as follows: reduction unit 403 is bright by the partial region of screen
Degree reduces.For example, when the first judging unit 402 is judged at least one iris information there are when unauthorized iris information,
The mobile terminal 400 will obtain content shown by the runnable interface of destination application, if in content including privacy
Information, reduction unit 403 will just show the region of privacy information luminance-value reduction in screen is target brightness value.For another example,
When destination application is instant messaging in application, judging to subtract there are when unauthorized iris information in the first judging unit 402
The brightness for the chat area that junior unit 403 can apply instant messaging reduces.
Optionally, when acquiring unit 401 gets at least one iris information, the first judging unit 402 judges this extremely
All iris informations in a few iris information are inconsistent with the default iris information of storage, then may indicate that the movement
Terminal 400 has been lost, or is used by unauthorized user.Therefore, which can be with lock-screen, and leads to
The image for crossing front camera crawl user, sends its picture on the mobile terminal bound in advance.It in this way can be in order to
User can quickly be aware of the loss of mobile terminal 400, and conveniently recover.
For example, when mobile terminal 400 starts wechat, the facial image in default angular field of view will be acquired, and
Iris information is obtained out from facial image, it is assumed that there are three the iris informations that acquiring unit 401 is got, then the first judgement
Unit 402 just judges in these three iris informations to be believed with the presence or absence of with the inconsistent iris of the iris information of the user of storage
Breath.Inconsistent if there is the iris information of an iris information and user, reduction unit 403 will further identify wechat
Chat window, and by the brightness in the region where the chat window reduce.
Again for example, when mobile terminal 400 starts address list, the face figure in default angular field of view can also be acquired
Picture, and iris information is obtained out from facial image, it is assumed that there are two the iris informations that acquiring unit 401 is got, then the
One judging unit 402 just judges in the two iris informations with the presence or absence of the rainbow inconsistent with the iris information of the user of storage
Film information.It is inconsistent if there is the iris information of an iris information and user, reduction unit 403 will lock-screen, and
The brightness of screen is adjusted to blank screen.

To need to carry out the application program of anti-peeping operation.If so, start unit 405 just starts anti-peeping mode；If it is not, just
Start the destination application with the Starting mode of common applications.
As an example it is assumed that the pre-set application program for needing to carry out anti-peeping operation of mobile terminal 400 is QQ, micro-
Letter, telephone directory, Alipay, financing application etc..So after the application icon that user clicks browser, the mobile terminal 400
When starting the browser application, second judgment unit 404 will judge that the browser is not to need to carry out anti-peeping behaviour
The application program of work, therefore, start unit 405 would not do anti-peeping measure to browser application, that is, be not turned on anti-peeping mould
Formula；And after the application icon that user clicks Alipay, which is starting the Alipay in application, second sentences
It is the application program for needing to carry out anti-peeping operation, therefore, start unit that disconnected unit 404, which will judge that the Alipay is applied,
405 will start anti-peeping mode, to guarantee that user uses the safety of Alipay.
Start unit 405, for judging that the destination application is to be prevented in above-mentioned second judgment unit 404
