The embodiment of the invention discloses a kind of glance prevention method and mobile terminal, detect there is unauthorized iris information time, preventing information leakage by reducing screen intensity, improving the security of mobile terminal.Below be described in detail respectively.
Refer to Fig. 1, Fig. 1 is the schematic flow sheet of a kind of glance prevention method disclosed in the embodiment of the present invention.Wherein, method shown in Fig. 1 can be applied to smart mobile phone (as Android phone, iOS mobile phone etc.), panel computer, palm PC and mobile internet device (MobileInternetDevices, MID), the mobile terminal such as personal digital assistant (PersonalDigitalAssistant, PDA), media player, intelligent television, intelligent watch, intelligent glasses, Intelligent bracelet.As shown in Figure 1, this glance prevention method can comprise the following steps:
S101, when start destination application time, acquisition for mobile terminal presets at least one iris information in angular field of view.
In the embodiment of the present invention, maximum angular field of view when default angular field of view can be the front-facing camera shooting image of mobile terminal, can be also a part for maximum angular field of view during this front-facing camera shooting image, the embodiment of the present invention limit.User can browse to content shown on the screen of mobile terminal in this default angular field of view.
Wherein, any one or several application program that destination application can be installed for mobile terminal, also can be one or several application program in application-specific, the embodiment of the present invention limit.If this destination application can be the application program that address list, message registration, note, micro-letter, QQ, microblogging, MSN, picture library etc. relate to privacy of user, certain application program in instant messaging class application program also can be refered in particular to.
In the embodiment of the present invention, when user needs to open destination application, can touch or click the application icon of this destination application, after this mobile terminal detects the operation of user, this destination application will be started, and the image preset by front-facing camera collection in angular field of view, from the image collected, parse one or more facial image.Thus, this mobile terminal just can obtain out different iris information from each facial image.Wherein, the iris information quantity of acquisition depends on the human eye quantity that the facial image collected in default angular field of view comprises.Meanwhile, can be understood as and only have when the content shown by screen reflects (namely the sight line of human eye drops on screen) from human eye, this mobile terminal just can identify iris information.
In the embodiment of the present invention, the iris information due to everyone also exists certain difference, so by identifying the iris information of different people, namely can identify the identity of different people.Therefore, it is only most suitable for being carried out authentication by iris information thus realized anti-peeping.
S102, this mobile terminal judge whether there is unauthorized iris information in this at least one iris information, if so, perform step S103; If not, process ends.
In the embodiment of the present invention, mobile terminal can be previously stored with the iris information of user, and the iris information of this user is mandate iris information, and mobile terminal can according to the identity of authorizing iris information to identify user.Wherein, authorize iris information can be one, also can be multiple, namely can be the iris information of user oneself, also can include the iris information of user friend or household, the embodiment of the present invention limit.And unauthorized iris information is and authorize iris information not mate or inconsistent iris information, that is, the identity of user can not be identified from unauthorized iris information.Therefore, after startup destination application, only have iris information to verify and pass through, and when there is not the failed iris information of verification in default angular field of view, user could perform next step to this destination application and operate.
Therefore, after acquisition for mobile terminal at least one iris information preset in angular field of view, authentication will being carried out to each iris information in this at least one iris information, be proved to be successful, namely representing that this iris information is for authorizing iris information; And checking identifies, namely represent that this iris information is unauthorized iris information.Therefore, as long as when there is unauthorized iris information in this at least one iris information, the brightness value of its screen just can reduce by this mobile terminal.And if be mandate iris information in this at least one iris information, so mobile terminal would not make any adjustments the present intensity value of screen.
Wherein, unauthorized iris information can be one, and also can be multiple, the embodiment of the present invention limit.
As a kind of feasible embodiment, this mobile terminal judges that the concrete mode that whether there is unauthorized iris information in this at least one iris information can comprise the following steps:
Step 11) judge in this at least one iris information, whether to there is the iris information inconsistent with the default iris information stored.
In specific implementation, after acquisition for mobile terminal at least one iris information preset in angular field of view, can judge that whether each iris information got is consistent with the default iris information of storage further, if consistent, just determine that this iris information is for authorizing iris information, and continue to judge until judge the iris information inconsistent with default iris information next iris information.
Step 12) when judging to exist in this at least one iris information with the iris information that the default iris information stored is inconsistent, determine to there is unauthorized iris information in this at least one iris information.
That is, the iris information consistent with the default iris information stored is for authorize iris information, and the iris information inconsistent with the default iris information stored is unauthorized iris information.Therefore, when mobile terminal is judged to exist in this at least one iris information with the iris information that the default iris information stored is inconsistent, just can determine to there is unauthorized iris information in this at least one iris information.Therefore, the brightness value of its screen just can reduce by this mobile terminal further.
The brightness value of screen is reduced to target brightness value by S103, this mobile terminal, and process ends.
In the embodiment of the present invention, when judging to there is unauthorized iris information in this at least one iris information, this mobile terminal will obtain the brightness value of its screen, and this brightness value is decreased to target brightness value.Wherein, under target brightness value, the nearer user's (namely using the user of this mobile terminal) of distance screen can content clearly shown by browse screen, and the content that the user that distance screen is far away (may for the user peeped) can not be able to browse to shown by screen because screen intensity is inadequate.
Further, this target brightness value can be less than the present intensity value of screen, and can also be zero, namely this mobile terminal directly controls screen blank screen, and the embodiment of the present invention does not limit.
In the embodiment of the present invention, the brightness value of screen is reduced to target brightness value by mobile terminal, can be understood as: the brightness of whole screen reduced; Also can be understood as: the brightness of the subregion of screen is reduced.Such as, when judging to there is unauthorized iris information in this at least one iris information, this mobile terminal will obtain the content shown by the runnable interface of destination application, if include privacy information in content, just the brightness value in the region showing privacy information in screen is reduced to target brightness value.And for example, when destination application is instant messaging application, this mobile terminal is when judging to there is unauthorized iris information, and the brightness of chat area instant messaging can applied reduces.
Optionally, this mobile terminal is when getting at least one iris information, and judge that all iris information in this at least one iris information are all inconsistent with the default iris information stored, so can show this mobile terminal or lose, or being used by unauthorized user.Therefore, this mobile terminal can also lock-screen, and captures the image of user by front-facing camera, sends its picture on the mobile terminal bound in advance.So that user can aware mobile terminal loss fast, and conveniently can recover like this.
For example, when mobile terminal starts micro-letter, the facial image in default angular field of view will be gathered, and iris information is obtained out from facial image, suppose that the iris information got has three, so this mobile terminal will judge whether there is the iris information inconsistent with the iris information of the user stored in these three iris information.If the iris information that there is an iris information and user is inconsistent, this mobile terminal will identify the chat window of micro-letter further, and the brightness in the region at this chat window place is reduced.
Again for example, when mobile terminal starts address list, also the facial image in default angular field of view can be gathered, and iris information is obtained out from facial image, suppose that the iris information got has two, so this mobile terminal will judge whether there is the iris information inconsistent with the iris information of the user stored in these two iris information.If the iris information that there is an iris information and user is inconsistent, this mobile terminal will lock-screen, and the brightness of screen is adjusted to blank screen.
Visible, in the method described by Fig. 1, when starting destination application, mobile terminal can obtain at least one iris information, and judge whether there is unauthorized iris information in this at least one iris information, if there is unauthorized iris information, just the brightness value of screen is reduced to target brightness value.By the embodiment of the present invention, detect there is unauthorized iris information time, mobile terminal can prevent from being peeped by reducing screen intensity, can prevent the information leakage of user like this, thus improve the security of mobile terminal displaying contents.
Refer to Fig. 2, Fig. 2 is the schematic flow sheet of another kind of glance prevention method disclosed in the embodiment of the present invention.Wherein, the method shown in Fig. 2 can be applied to the mobile terminal such as smart mobile phone (as Android phone, iOS mobile phone etc.), panel computer, palm PC and mobile internet device, personal digital assistant, media player, intelligent television, intelligent watch, intelligent glasses, Intelligent bracelet.As shown in Figure 2, this glance prevention method can comprise the following steps:
S201, when start destination application time, acquisition for mobile terminal presets at least one iris information in angular field of view.
S202, this mobile terminal judge whether there is unauthorized iris information in this at least one iris information, if so, perform step S203; If not, process ends.
S203, this mobile terminal detect the distance between human eye corresponding to each unauthorized iris information and screen.
In the embodiment of the present invention, unauthorized iris information can be one, and also can be multiple, the embodiment of the present invention limit.Therefore, when mobile terminal judges to there is unauthorized iris information in this at least one iris information, for each unauthorized information, the distance between the human eye of its correspondence and screen can be detected.Therefore, the distance that mobile terminal detects is one to one with the unauthorized iris information judged.
Under normal circumstances, the mode of the distance that this mobile terminal detects between human eye corresponding to each unauthorized iris information and screen can be: after unauthorized iris information being detected, the shooting direction at the human eye place corresponding to this iris information can be determined, detect the distance corresponding to unauthorized iris information between human eye and screen by Emission Lasers or ray etc.
Concrete, the mode of the distance that this mobile terminal detects between human eye corresponding to each unauthorized iris information and screen can also be: the object that user can see can form image in the pupil of eyes of user, and this image can be collected by other-end or equipment.Generally, the object nearer apart from human eye accounts for the large percentage of the whole image of pupil when pupil image, and the object far away apart from human eye accounts for the whole image of pupil ratio when pupil image is less.Therefore, mobile terminal can detect the distance of its screen from human eye according to the mobile terminal got in the ratio of pupil image.
S204, this mobile terminal distance that selected value is minimum from this distance are as target range.
In the embodiment of the present invention, the sight line due to human eye is subject to the impact of the factors such as distance, light intensity.So in same brightness environment, for same object, the sharpness that user sees in different distance is different; In other words under same distance, for same object, the sharpness that different lightness environment can cause user to see is different.Therefore, if when user is using mobile phone brush webpage, if human eye is close to screen, more easily clearly see the content that mobile phone shows, and if human eye away from screen, so user more difficultly will clearly see the content that mobile phone shows.
And generally, user is when using mobile terminal, the screen of distance mobile terminal is nearest often.And other users can be far away apart from screen, so, if there is multiple unauthorized iris information, mobile terminal just selected distance can be worth the distance of human eye and screen corresponding to minimum unauthorized iris information as target range, as long as then reduce brightness can ensure that user can not know that the content shown by browsing in screen is just passable under target range.
In the embodiment of the present invention, after mobile terminal detects the distance between human eye corresponding to each unauthorized iris information and screen, can by comparing the little of distance value, the distance that selected value is minimum from the distance detected is as target range.
Further, if when unauthorized iris information only has one, so corresponding to this unauthorized iris information, namely the distance of human eye and screen can be used as target range.
For example, when supposing that mobile phone judges that unauthorized iris information has three, in the pupil image of the human eye corresponding to these three unauthorized iris information that mobile phone captures, mobile phone accounts for whole imaging area ratio when pupil image can be got, then based on experience value or special algorithm, the distance calculating mobile phone distance human eye is respectively 60cm, 54cm and 73cm, by comparing, is easy to select the target range of distance as adjusting screen brightness that distance value is 54cm.
S205, this mobile terminal search the target brightness value corresponding with this target range from the distance preset with brightness value relation.
In the embodiment of the present invention, distance can be understood as with the relation of brightness value: under some distances, when the screen of mobile terminal is adjusted to a certain brightness value, major part user clearly can not see the content shown in screen just, and so this distance and this brightness value can be stored in distance with the relation of brightness value.Therefore, Distance geometry brightness values is one to one.
Concrete, after mobile terminal selects target range, just can find the target brightness value corresponding with target range from distance with brightness value relation.So when the brightness value of screen is adjusted to target brightness value by mobile terminal, the user corresponding to unauthorized iris information that the screen of distance mobile terminal is nearest just can not peep the content shown in screen, equally also can ensure that user self can comparatively be easy to browse to the content shown in screen.
The brightness value of screen is reduced to target brightness value by S206, this mobile terminal, and process ends.
Visible, in the method described by Fig. 2, mobile terminal is when judging to there is unauthorized iris information in this at least one iris information, the distance between human eye and screen corresponding to each unauthorized iris information can be detected, the screen brightness value of mobile terminal as target range, and is adjusted to the target brightness value corresponding with target range by the distance that then selected value is minimum from these distances.Can ensure that user corresponding to nearest unauthorized iris information can not peep the content shown in screen like this, and can ensure to authorize user corresponding to iris information normally to use mobile terminal.The security of the guarantee information of mobile terminal of hommization more, promotes Consumer's Experience.
Refer to Fig. 3, Fig. 3 is the schematic flow sheet of the embodiment of the present invention another glance prevention method disclosed.Wherein, the method shown in Fig. 3 can be applied to the mobile terminal such as smart mobile phone (as Android phone, iOS mobile phone etc.), panel computer, palm PC and mobile internet device, personal digital assistant, media player, intelligent television, intelligent watch, intelligent glasses, Intelligent bracelet.As shown in Figure 3, this glance prevention method can comprise the following steps:
S301, when start destination application time, mobile terminal judges whether this destination application is the application program needing to carry out anti-peeping operation, if so, perform step S302; If not, process ends.
In the embodiment of the present invention, mobile terminal can pre-set certain applications program to be needed to carry out anti-peeping operation when starting.As arranged instant messaging class application program and note, telephone directory etc. as the application program needing to carry out anti-peeping operation.
Therefore, when starting destination application, first this mobile terminal can judge whether this destination application is the application program needing to carry out anti-peeping operation.If so, anti-peeping pattern is just started; If not, just start this destination application with the Starting mode of common applications.
For example, suppose that the application program of carrying out anti-peeping operation that needs that mobile terminal pre-sets is QQ, micro-letter, telephone directory, Alipay, financing application etc.So after the application icon of user's click browser, this mobile terminal is when starting this browser application, will judge that this browser is not the application program needing to carry out anti-peeping operation, anti-peeping measure would not be done to browser application, namely not open anti-peeping pattern; And after user clicks the application icon of Alipay, this mobile terminal is when starting the application of this Alipay, will judge that this Alipay is applied as the application program needing to carry out anti-peeping operation, therefore can start anti-peeping pattern, to ensure that user uses the security of Alipay.
S302, this mobile terminal start anti-peeping pattern, and open front-facing camera in system background.
In the embodiment of the present invention, under anti-peeping pattern, by a series of safeguard procedures (i.e. anti-peeping operation), mobile terminal can ensure that user is when using mobile terminal, in screen, displaying contents can not be peeped by other users.Therefore, when mobile terminal judges that destination application is the application program needing to carry out anti-peeping operation, this mobile terminal will start anti-peeping pattern automatically, and automatically opens front-facing camera in system background under anti-peeping pattern.Therefore, time in need, just start anti-peeping pattern in this way, and anti-peeping pattern need not be started always, thus save the resource consumption of mobile terminal, improve Consumer's Experience.
S303, this mobile terminal control this front-facing camera collection and preset at least one iris information in angular field of view.
In the embodiment of the present invention, when mobile terminal opens front-facing camera in system background, just can control front-facing camera collection and preset at least one iris information in angular field of view.
S304, this mobile terminal judge whether there is unauthorized iris information in this at least one iris information, if so, perform step S305; If not, process ends.
The brightness value of screen is reduced to target brightness value by S305, this mobile terminal.
S306, this mobile terminal take this facial image corresponding to unauthorized iris information, and export this facial image to screen, and process ends.
In the embodiment of the present invention, step S306 can perform before step S305, also can perform after step S305, and can also perform with step S305, the embodiment of the present invention does not limit simultaneously.
Concrete, after its screen brightness value is reduced to target brightness value by mobile terminal, this mobile terminal just can control front-facing camera and take this facial image corresponding to unauthorized iris information, then on mobile terminal screen, exports this facial image.
If there is multiple unauthorized iris information, this mobile terminal will identify the position of human eye corresponding to each unauthorized iris information respectively, and go out whole facial image corresponding to unauthorized iris information according to location recognition, then this facial image is taken, each facial image of shooting is all shown on the screen of the mobile terminal, to point out user the current user profile peeped.
As a kind of feasible embodiment, after its screen brightness value is reduced to target brightness value by mobile terminal, this mobile terminal simply can also export information, and this information exists unauthorized iris information for pointing out user.
In specific implementation, this information can be understood as pointing out user to there is unauthorized iris information: this information is peeped for pointing out user to there are other users.Therefore, mobile terminal can export as informations such as " the current people of having are peeping ".So not only can point out user, " person of peeping " can also be pointed out to stop peeping, can more effectively stop " person of peeping " to peep.
Visible, in the method described by Fig. 3, mobile terminal can perform anti-peeping operation for certain applications program, that is, when startup needs the application program of carrying out anti-peeping operation, mobile terminal just can start anti-peeping pattern, not only can reduce the power consumption of mobile terminal, can also saving resource consumption.Thus the performance of lifting mobile terminal.Meanwhile, when there is unauthorized iris information, not only can reduce screen intensity, directly can also intercept the facial image of user corresponding to unauthorized iris information, thus the information of more intuitive understanding " person of peeping ", promote Consumer's Experience.
Refer to Fig. 4, Fig. 4 is the structural representation of a kind of mobile terminal disclosed in the embodiment of the present invention.Wherein, the mobile terminal 400 shown in Fig. 4 can include but not limited to smart mobile phone (as Android phone, iOS mobile phone etc.), panel computer, palm PC and mobile internet device, personal digital assistant, media player, intelligent television, intelligent watch, intelligent glasses, Intelligent bracelet etc.As shown in Figure 4, this mobile terminal 400 can comprise with lower unit:
Acquiring unit 401, for when starting destination application, obtains at least one iris information preset in angular field of view.
In the embodiment of the present invention, maximum angular field of view when default angular field of view can be the front-facing camera shooting image of mobile terminal 400, can be also a part for maximum angular field of view during this front-facing camera shooting image, the embodiment of the present invention limit.User can browse to content shown on the screen of mobile terminal 400 in this default angular field of view.
Wherein, any one or several application program that destination application can be installed for mobile terminal 400, also can be one or several application program in application-specific, the embodiment of the present invention limit.If this destination application can be the application program that address list, message registration, note, micro-letter, QQ, microblogging, MSN, picture library etc. relate to privacy of user, certain application program in instant messaging class application program also can be refered in particular to.
In the embodiment of the present invention, when user needs to open destination application, can touch or click the application icon of this destination application, after this mobile terminal 400 detects the operation of user, this destination application will be started, and the image preset by front-facing camera collection in angular field of view, from the image collected, parse one or more facial image.Thus, acquiring unit 401 just can obtain out different iris information from each facial image.Wherein, the iris information quantity of acquisition depends on the human eye quantity that the facial image collected in default angular field of view comprises.Meanwhile, can be understood as and only have when the content shown by screen reflects (namely the sight line of human eye drops on screen) from human eye, acquiring unit 401 just can identify iris information.
In the embodiment of the present invention, the iris information due to everyone also exists certain difference, so by identifying the iris information of different people, namely can identify the identity of different people.Therefore, it is only most suitable for being carried out authentication by iris information thus realized anti-peeping.
First judging unit 402, for judging whether there is unauthorized iris information in this at least one iris information that above-mentioned acquiring unit 401 gets.
In the embodiment of the present invention, mobile terminal 400 can be previously stored with the iris information of user, and the iris information of this user is mandate iris information, and mobile terminal 400 can according to the identity of authorizing iris information to identify user.Wherein, authorize iris information can be one, also can be multiple, namely can be the iris information of user oneself, also can include the iris information of user friend or household, the embodiment of the present invention limit.And unauthorized iris information is and authorize iris information not mate or inconsistent iris information, that is, the identity of user can not be identified from unauthorized iris information.Therefore, after startup destination application, only have iris information to verify and pass through, and when there is not the failed iris information of verification in default angular field of view, user could perform next step to this destination application and operate.
Therefore, get at least one iris information in default angular field of view when acquiring unit 401 after, first judging unit 402 will carry out authentication to each iris information in this at least one iris information, is proved to be successful, and namely represents that this iris information is for authorizing iris information; And checking identifies, namely represent that this iris information is unauthorized iris information.Therefore, as long as when there is unauthorized iris information in this at least one iris information, reduce unit 403 and just the brightness value of its screen can be reduced.And if be mandate iris information in this at least one iris information, so reduce unit 403 would not make any adjustments the present intensity value of screen.
Wherein, unauthorized iris information can be one, and also can be multiple, the embodiment of the present invention limit.
Reduce unit 403, for when above-mentioned first judging unit 402 judges to there is unauthorized iris information in this at least one iris information, the brightness value of screen is reduced to target brightness value.
In the embodiment of the present invention, when judging to there is unauthorized iris information in this at least one iris information, this mobile terminal 400 will obtain the brightness value of its screen, and this brightness value is decreased to target brightness value.Wherein, under target brightness value, the nearer user's (namely using the user of this mobile terminal) of distance screen can content clearly shown by browse screen, and the content that the user that distance screen is far away (may for the user peeped) can not be able to browse to shown by screen because screen intensity is inadequate.
Further, this target brightness value can be less than the present intensity value of screen, and can also be zero, namely this mobile terminal directly controls screen blank screen, and the embodiment of the present invention does not limit.
In the embodiment of the present invention, reduce unit 403 and the brightness value of screen is reduced to target brightness value, can be understood as: reduce unit 403 and the brightness of whole screen is reduced; Also can be understood as: reduce unit 403 and the brightness of the subregion of screen is reduced.Such as, when the first judging unit 402 judges to there is unauthorized iris information in this at least one iris information, this mobile terminal 400 will obtain the content shown by runnable interface of destination application, if include privacy information in content, reduce unit 403 and just the brightness value in the region showing privacy information in screen is reduced to target brightness value.And for example, when destination application is instant messaging application, when the first judging unit 402 judges to there is unauthorized iris information, the brightness reducing the chat area that instant messaging can be applied by unit 403 reduces.
Optionally, when acquiring unit 401 gets at least one iris information, first judging unit 402 judges that all iris information in this at least one iris information are all inconsistent with the default iris information stored, so can show this mobile terminal 400 or lose, or being used by unauthorized user.Therefore, this mobile terminal 400 can also lock-screen, and is captured the image of user by front-facing camera, sends its picture on the mobile terminal bound in advance.So that user can aware mobile terminal 400 fast loses, and conveniently can recover like this.
For example, when mobile terminal 400 starts micro-letter, the facial image in default angular field of view will be gathered, and iris information is obtained out from facial image, suppose that the iris information that acquiring unit 401 gets has three, so the first judging unit 402 will judge whether there is the iris information inconsistent with the iris information of the user stored in these three iris information.If the iris information that there is an iris information and user is inconsistent, reduces the chat window that unit 403 will identify micro-letter further, and the brightness in the region at this chat window place is reduced.
