Embodiment
The embodiment of the present invention provides a kind of method and apparatus that unauthorized user is read display content of electronic equipment of identifying, and can solve electronic equipment of the prior art and can't prevent that other people from spying on screen content, easily causes the problem that shows leakage of information.
The embodiment of the present invention provides a kind of method that unauthorized user is read display content of electronic equipment of identifying, and as shown in Figure 1, comprises the following steps:
S101: according to the biological information of all users in acquisition testing zone, Preset Time interval, wherein, described surveyed area is for observing the zone of display content of electronic equipment.
S102: the biological information of all users' of gathering biological information and pre-stored authorized user is compared.
S103: determine the biological information that whether has unauthorized user in all users' the biological information of described collection.
Wherein, while in the biological information of determining the described all users that obtain, having the biological information of unauthorized user, can further judge the biological information that whether has authorized user in the described all users' that obtain biological information, when having the biological information of authorized user, show the information that has unauthorized user; When not having the biological information of authorized user, close the displaying contents of electronic equipment.
Perhaps, while in the biological information of determining the described all users that obtain, having the biological information of unauthorized user, also can close the displaying contents of electronic equipment, and to the message of user's display requirement input validation information, after the correct authorization information that receives user's input, show the displaying contents of electronic equipment.
In addition, while in the biological information of determining the described all users that obtain, not having the biological information of unauthorized user, can further judge the biological information that whether has authorized user in the described all users' that obtain biological information, when not having the biological information of authorized user, close the displaying contents of electronic equipment, and to the message of user's display requirement input validation information, after the correct authorization information that receives user's input, show the displaying contents of electronic equipment.
Preferably, the method also comprises: opening in display content of electronic equipment, selecting to start the function of the user biological characteristic information in acquisition testing zone.
By adopting the method in the present embodiment, pre-stored its biological information of the legal user of electronic equipment, thereby become authorized user, regularly detect user's biological information in the operational process of electronic equipment, thereby can identify unauthorized user, take corresponding counter-measure according to recognition result, thereby avoid leakage of information.
Below with a preferred embodiment, describe in detail the method that identification unauthorized user provided by the invention is read display content of electronic equipment.In this preferred embodiment, the biological information behaviour face identifying information of take describes as example, but, those skilled in the art should understand that, other biological information, also can be for the identification of authorized user such as iris information etc., in a word, so long as biological information that can unique definite user identity can be used.
The method that this identification unauthorized user is read display content of electronic equipment mainly comprises the following steps:
Step 1, open electronic equipment, and the face image information of pre-stored authorized user.
In this step, the main initial setting up realized for electronic equipment, so that this electronic equipment can be applied the method that identification unauthorized user provided by the invention is read.At first, the legal user of electronic equipment is by selecting the modes such as corresponding drop-down menu to enter the state of " validated user is set ", then, built-in or the external camera head of electronic equipment is aimed to by face, by camera head, legal user's face is taken pictures, gather and store this legal user's face image information, as the face image information of authorized user.Wherein, when this electronic equipment, during only for a user, set authorized user is only one; When this electronic equipment is a plurality of users while jointly using, set authorized user can be a plurality of.
Step 2, in the operational process of electronic equipment, according to the face image information of all users in Preset Time interval acquiring surveyed area.
Set the relevant information of authorized user by step 1 after, when this electronic equipment enters running status, camera head can regularly obtain according to the Preset Time interval all users' that appear in surveyed area face image information.In order effectively to prevent that other people from peeping, can set in advance the shooting angle of camera head, the surveyed area that it is photographed is just consistent with the zone that can observe display content of electronic equipment, once have the people to enter this surveyed area can be taken lower face image information by the shooting device, can adopt any camera technique that comprises infrared photography during shooting.Particularly, if surveyed area arranges too smallly, when having the people to peep aside, can't find; If surveyed area arranges too much, can because at a distance some incoherent people occurring, the operation of execution error cause interference to the user, therefore, the size of surveyed area should rationally arrange.
Preferably, the camera head in this step can open or cut out according to user's needs.For example, when the user reads the document of certain need to be keep secret, can open camera head, make camera head in running status, peep preventing; When the user reads the document of some not needs to be keep secret, can close camera head, thereby save power consumption.
Figure 2 shows that example, when electronic equipment 21 is moving, 22 pairs of surveyed areas 23 of camera head are detected, and all users that appear in surveyed area 23 will be detected and record face image information by shooting device 22.Surveyed area 23 can be observed the zone of the displaying contents of electronic equipment exactly.In the situation shown in Fig. 2, interior authorized user 24 and the unauthorized user 25 of simultaneously having occurred of surveyed area 23, therefore, the face image information of authorized user 24 and unauthorized user 25 all can be recorded by shooting device 22.
In addition, in order to find more in time the person of peeping, can the time interval when obtaining face image information arrange enough littlely, to reach the effect of Real-Time Monitoring.
Step 3, the face image information of the authorized user stored in the face image information of all users in the surveyed area obtained and step 1 is compared.
Particularly, when comparison, can determine that whether face image information is consistent by recognition of face software.While in surveyed area, a plurality of user being detected, a plurality of users' face image information need to be compared with the face image information of authorized user one by one.In addition, while in step 1, having stored a plurality of authorized user, also need the user in surveyed area is compared one by one with a plurality of authorized users respectively, can not occur omitting, in order to avoid cause erroneous judgement.In addition, if after opening camera function, judged and had an authorized user, at this moment, monitored again other people people's face information if follow-up, other people people's face information that also can only will follow-uply monitor is compared with the authorized user face image information of storage, and does not need the authorized user to having judged again to compare, thereby complexity is monitored in reduction.
The situation shown in Fig. 2 of still take describes as example, in this step, by comparison, finds that the face image information of the authorized user 24 that detects is consistent with the face image information of the authorized user of storage, therefore determines that the user is authorized user; The face image information of the face image information of discovery unauthorized user 25 and the authorized user of storage is inconsistent, therefore determines that the user is unauthorized user.
Step 4, there is the face image information of unauthorized user in the face image information of determining the described all users that obtain, or determine in the described all users' that obtain face image information while not having the face image information of authorized user, carry out default operation, to prevent leakage of information.
Wherein, in this step, as long as find that testing result has occurred extremely, just need to carry out the operation that prevents leakage of information., according to different mode classifications, abnormal conditions can be divided into to two kinds of situations here, the first situation is: the face image information that unauthorized user detected in step 3.The second situation is: the face image information that any authorized user do not detected in step 3.During subsequent treatment, can only according to the first situation, be processed separately, also can only be processed separately according to the second situation, or, also both of these case can be combined and processed.In a word, as long as can reach the purpose that prevents leakage of information.
Particularly, when being processed for abnormal conditions, can adopt following two kinds of processing modes:
In the first processing mode, can will either way adopt unified processing mode to be processed.For example, can be when the face image information of unauthorized user being detected, perhaps, when the face image information of any authorized user not detected, the content that the temporary close electronic equipment is shown, for example, during by the ocr software browse displays content on electronic equipment, can temporarily exit the ocr software that this electronic equipment is moving at present as the user, or, displaying contents that also can electronic equipment is set to grey, makes its content invisible etc.Simultaneously, can also on screen, eject prompting frame or the message that requires user's input validation information, only after the correct authorization information that receives user's input, just normally show the displaying contents of electronic equipment, if the authorization information mistake of user input or do not input any information, the shown content of electronic equipment will be always in closed condition, thereby avoids showing the leakage of information.Here, authorization information can be the information that authorized user arranges in advance, as password or prompting problem etc.By such mode, once unusual circumstance, no matter be unauthorized user to have been detected, does not still detect authorized user, all close without exception the displaying contents of electronic equipment, require the user to input correct authorization information, thereby thoroughly prevent the leakage of information.In this processing mode, the situation of take in Fig. 2 is example, can at first close the displaying contents of electronic equipment, and require the active user to input correct authorization information, to prevent unauthorized user, sees displaying contents.At this moment, if unauthorized user 25 is not colleague or the friend of authorized user 24, but peep personnel, can be authorized to user 24 and discover in time; And if unauthorized user 25 is colleague or the friend of authorized user 24, electronic equipment can normally move after the authorization information correct in authorized user 24 inputs.
In the second processing mode, while being processed for abnormal conditions, can according to circumstances be processed respectively.For example, when detecting while unauthorized user occurring, further judge whether to have authorized user simultaneously, if there is authorized user simultaneously, can not require user's input validation information, and show the information of " unauthorized user being detected " to the user.Particularly, information can adopt any demonstration the in three kinds of forms shown in Fig. 3, for example, can on screen, show the icon 31 in Fig. 3, this icon can present beat, concavo-convex or change color texts, thereby cause user's attention; Also can on screen, show the prompting frame 32 in Fig. 3, the prompting user has detected unauthorized user, requires the user to indicate whether to continue operation; Can also on screen, show the warning mark 33 in Fig. 3, this warning mark 33 can be dynamic or static pattern or word, to reach prompting user's effect.
During specific implementation, three kinds of prompting modes in Fig. 3 can be used separately also and can be combined with.When receiving the confirmation information that the user sends, for example the user has selected "Yes" in the prompting frame 32 shown in Fig. 3, and electronic equipment continues normal operation; When receive that the user sends deny information the time, as the user has selected "No", or do not receive any operation of user within the default time, electronic equipment is by temporary close, to prevent leakage of information.In addition, when authorized user not detected, no matter at this moment whether there is unauthorized user, all will directly close electronic equipment, to prevent leakage of information.In this processing mode, the situation shown in Fig. 2 of still take describes as example, owing to both there being unauthorized user in Fig. 2, there is again authorized user, therefore, to eject information, prompting user current detection has arrived unauthorized user, for example, eject the prompting frame 32 in Fig. 3, at this moment, if unauthorized user 25 is colleague or the friend of authorized user 24, be that unauthorized user 25 is that authorized user 24 can directly be selected "Yes", thereby continues the normal running electronic equipment in the situation that authorized user 24 is in the know appears at before computer; If unauthorized user 25 is not colleague or the friend of authorized user 24, be that unauthorized user 25 is peeped in the unwitting situation of authorized user 24, authorized user 24 can be selected "No", thereby close electronic equipment, perhaps require unauthorized user 25 to avoid, reach the purpose that prevents leakage of information.In this mode, when having authorized user and unauthorized user, only to the user, send information simultaneously, whether continue operation by the own decision of user, thereby both can prevent the leakage of information, can avoid again the troublesome operation of user's input validation information; When not having authorized user, directly close displaying contents, prevent leakage of information.
Above-mentioned two kinds of processing modes both can be used separately also and can be combined with.For example, also can exist at the same time in the situation of authorized user and unauthorized user, show the information that has unauthorized user to the user; And in the situation that there is not authorized user, closes displaying contents and require input validation information.
In addition, in the present embodiment, can also when unauthorized user being detected, the biological information of unauthorized user be stored separately, so that determine the identity information of unauthorized user in the future.
In the embodiment of the present invention, when unauthorized user being detected, or away from keyboard when authorized user, while can't detect authorized user, can take measures the leakage of the information that prevents.In addition, the method in the present embodiment can be applied to respectively various electronic, as computing machine, electronic reader, PDA etc.
