Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in the accompanying drawing, yet should be appreciated that and to realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order to understand the disclosure more thoroughly that these embodiment are provided, and can with the scope of the present disclosure complete convey to those skilled in the art.
Main characteristics of intelligent television are to have carried operating system, and have open platform, make the user not only can watch the common TV content, but also can install voluntarily and unload types of applications software.Therefore, the protection of the camera of intelligent television is even more important.
For the demand, the embodiment of the invention provides a kind of telephotography means of defence and system, carry the application stack tabulation corresponding to application program of current operation of the intelligent television of operating system by Real-Time Monitoring, to using the stack top process in the stack tabulation, check whether it has registered the authority of operation camera, if registered the authority of operation camera, then further determine according to blacklist and/or white list whether described stack top process is legal, if described stack top process is illegal, then stop described stack top process operation, thereby realized monitoring that user's camera is called, effectively prevented the privacy of user leakage.
As shown in Figure 1, be the flow chart of an according to an embodiment of the invention telephotography means of defence.
The method may further comprise the steps:
Because no matter which kind of operating system intelligent television carry, when the application program operation of its installation, all can be recorded in process that should application program and to use in the stack tabulation.Described process is the running example of application program, is a Dynamic Execution of application program, it can be interpreted as simply the executive program of the current operation of operating system.In the executive program of the current operation of system, comprise: system management intelligent television and finish the necessary program of various operations; The additional programs that the user opens, carries out comprises also that certainly the user does not know, and the illegal program that automatically moves.
Therefore, by the described application stack tabulation of Real-Time Monitoring, can obtain all processes of current operation.And when each application program was moved first, its corresponding process all can be recorded in the stack top of using the stack tabulation.
Particularly, the screen management device interface that can utilize the SDK (SDK, Sofeware Development Kit) of described operating system to provide by the background service program, the described application stack tabulation of Real-time Obtaining.
Such as, for the intelligent television that carries Android operating system, can by the getRunningTasks method of ActivityManager, obtain and use the stack tabulation.
Step 102 is obtained the stack top process from described application stack tabulation.
Extract first data in the described application stack tabulation, be the stack top process.
Step 103 checks whether described stack top process has registered the authority of operation camera.
When the stack top process is carried out scope check, can at first obtain application bag name corresponding to described stack top process, particularly, can utilize the method in the package manager interface that SDK provides to obtain application bag name corresponding to described stack top process.Then the package manager interface that utilizes SDK to provide determines whether the stack top process with described application bag name has registered the authority that operates camera.
Such as, for the intelligent television that carries Android operating system, the stack top that can utilize SDK to provide is used the getPackageName method of topActivity attribute and is obtained current application bag name.Then, with the application bag name that obtains and the operation camera authority that needs to check import checkPermission method in the PackageManager interface that SDK provides into, whether the stack top process that the result who returns according to the checkPermission method can determine to have described application bag name has registered the authority of operation camera.
Need to prove, whether each process has the authority of operation camera, be to register to described operating system when application and development corresponding to this process, if the registered authority of operation camera, then the checkPermission method will normally be returned.
Step 104 if registered the authority of operation camera, then determines according to blacklist and/or white list whether described stack top process is legal.
If the authority of operation camera has been registered in certain application, illustrate that this application can call camera.For the operating system with open platform, as long as any application can operate the authority of camera based on this operating system to described operating system registration when exploitation.That is to say that the authority of operation camera has been registered in certain application, then this application just may operate camera, and no matter this application is legal or illegal.
Therefore, in embodiments of the present invention, as long as detect the authority that the stack top process has been registered the operation camera, in order to guarantee the personal secrets of camera, also will be further according to blacklist or white list or set up simultaneously black and white lists, determine whether described stack top process legal.
Certainly, if certain uses the authority of registration operation camera, then this application can not called camera, that is to say operation that can the executable operations camera.Therefore, if detect the authority that the stack top process is not registered the operation camera, can let slip this process, namely this process not intervened, make its normal operation.
Need to prove that above-mentioned blacklist and/or white list need to be collected the sample of some and set up in advance.Above-mentioned blacklist and/or white list can be kept at intelligent television this locality, also can be kept on the server.Therefore, in actual applications, can utilize local built-in blacklist and/or white list to carry out this locality and check, determine whether described stack top process is legal; Also can utilize blacklist and/or white list on the server to carry out long-range inspection, determine whether described stack top process is legal.Certainly, also can utilize simultaneously local built-in blacklist and/or the blacklist on white list and the server and/or white list respectively described stack top to be carried out validity checking.
Need to prove, if only adopting local built-in blacklist and/or white list that the stack top process is carried out this locality checks, then local built-in blacklist and/or white list need to server on up-to-date blacklist and/or white list keep synchronously, in a single day blacklist on the server and/or white list have renewal, then real-time synchronization is local to intelligent television, the concrete method of synchronization can adopt intelligent television request mode or server active push mode, and this embodiment of the invention is not done restriction.
Certainly, on intelligent television this locality and server, all preserve in the situation of above-mentioned blacklist and/or white list, when the stack top process is carried out validity checking, also can check at first whether local built-in blacklist and/or white list is latest edition by intelligent television, such as, its version information is uploaded to server, and server returns corresponding information to intelligent television.If latest edition is then only carried out this locality inspection, otherwise, carry out long-range inspection.
Above-mentioned blacklist and/or the white list of utilizing determined whether legal process of described stack top process, with to utilize virus base to carry out the process of virus filtration in the prior art similar, is not described in detail at this.
Step 105 if described stack top process is illegal, then stops described stack top process operation.
A telephotography of the present invention means of defence, carry the application stack tabulation corresponding to application program of current operation of the intelligent television of operating system by Real-Time Monitoring, to using the stack top process in the stack tabulation, check whether it has registered the authority of operation camera, if registered the authority of operation camera, then further determine according to blacklist and/or white list whether described stack top process is legal, if described stack top process is illegal, then stop described stack top process operation.Realized thus monitoring that user's camera is called effectively having prevented the privacy of user leakage.
Because the use of camera can have dual mode: a kind of is that the camera that directly creates is used, and another is that other application call camera is used.
Camera to above-mentioned first kind of way is used, and can by flow process shown in Figure 1, guarantee the fail safe that camera is used.
Camera for the above-mentioned second way is used, can whether legal by checking other process (being non-stack top process) in the described application stack tabulation, guarantee the fail safe that camera is used.Particularly, if described stack top process is legal, then from described application stack tabulation, obtain other process successively, then, determine according to described blacklist and/or white list whether other process of obtaining is legal, if illegal, then described other process operation of same prevention.Like this, can further guarantee the fail safe that the different modes camera is used.
As shown in Figure 2, be another flow chart of an according to an embodiment of the invention telephotography means of defence.
Wherein, step 201 is identical with flow process shown in Figure 1 to step 205, is specially:
Step 202 is obtained the stack top process from described application stack tabulation.
Step 203 checks whether described stack top process has registered the authority of operation camera.
Step 204 if registered the authority of operation camera, then determines according to blacklist and/or white list whether described stack top process is legal.If illegal, then execution in step 205; If legal, then execution in step 206; If whether can not determine legal, then execution in step 207.
Can not determine whether the stack top process is legal, refer to that application corresponding to described stack top process not in black, white list, in this case, can not determine accurately that this application is Secure Application or hazardous applications.
Step 205 stops described stack top process operation.
From shown in Figure 1 different be, in this embodiment, further comprising the steps of:
Step 206 is normally moved described stack top process.
Step 207 is carried out suspicious program prompts to the user.
Wherein, it can be the purpose that the prompting user current process has the operation camera that the user is carried out suspicious program prompts, and ejects dialog box, whether uses camera by user selection.
Step 208 if receive the instruction that user selection uses camera, is then moved described stack top process or described other process; If receive the instruction that user selection does not use camera, then stop described stack top process or described other process operation.
Bring potential safety hazard for fear of some dangerous processes to user's intelligent television, in actual applications, can also be when stoping described stack top process operation or stoping described other process operation, further the prompting user current process is dangerous, and the ejection dialog box, whether unload current process by user selection; If user selection unloading current process then guides the user to unload current process; If user selection does not unload current process, then current process is locked.Like this, the guiding user finishes the cleaning of dangerous process, has avoided some potential potential safety hazards.Owing to whether unload current process selected by the user fully, therefore also can not unload by force the more needed processes of user, both guaranteed the safety of camera privacy, convenient for users to use again.
Need to prove that above-mentioned steps 207 is to the process of step 208, and when quoting process that the user unloads current process and being equally applicable to that non-stack top process carried out validity checking, can't determine whether legal situation of corresponding process.
As shown in Figure 3, be another flow chart of an according to an embodiment of the invention telephotography means of defence.
Wherein, step 301 is identical with flow process shown in Figure 1 to step 305, is specially:
Step 302 is obtained the stack top process from described application stack tabulation.
Step 303 checks whether described stack top process has registered the authority of operation camera.
Step 304 if registered the authority of operation camera, then determines according to blacklist and/or white list whether described stack top process is legal.If illegal, then execution in step 305; If legal, then execution in step 306; If whether can not determine legal, then execution in step 307.
Can not determine whether the stack top process is legal, refer to that application corresponding to described stack top process not in black, white list, in this case, can not determine accurately that this application is Secure Application or hazardous applications.
Step 305 then stops described stack top process operation.
From shown in Figure 1 different be, in this embodiment, further comprising the steps of:
Step 306 is normally moved described stack top process.
Step 308 after the instruction that receives user selection use camera, stops replacement operation.
Need to prove that above-mentioned steps 307 is to the process of step 308, when being equally applicable to that non-stack top process carried out validity checking, can't determine whether legal situation of corresponding process.
The telephotography of this an embodiment means of defence, can't determine that according to blacklist and/or white list stack top process and other non-stack top process are whether in the legal situation, replace with the replacement data (such as image data) that presets by the video data with corresponding process requested, rather than directly the video flowing of camera is sent to corresponding process, and the ejection dialog box, whether use camera by user selection.Thereby guaranteed equally the safety of camera privacy.
This shows that the telephotography of an embodiment of the invention means of defence can prevent effectively that the telephotography head from by illegal applications exploiting, having strengthened user's personal secrets greatly.User's automatically early warning when using camera is illegally used, help the user to strengthen the camera secret protection.Need to prove that the telephotography of an embodiment of the invention means of defence can be applied to carry the intelligent television of various different operating systems, prevents that privacy of user from leaking by camera.
Correspondingly, the embodiment of the invention also provides a kind of telephotography guard system, as shown in Figure 4, is a kind of structural representation of this system.
In this embodiment, described system comprises: monitoring means 401, process acquiring unit 402, scope check unit 403, validity checking unit 404 and prevention unit 405.Wherein:

Described authority determines that package manager interface that subelement is used to utilize the SDK of described operating system to provide determines to have the authority whether the stack top process of described application bag name has registered the operation camera.Such as, for the intelligent television that carries Android operating system, described authority determines that subelement obtains the application bag name that subelement obtains with described bag name and the operation camera authority that needs to check is imported checkPermission method in the PackageManager interface that SDK provides into, and whether the stack top process that the result who returns according to the checkPermission method can determine to have described application bag name has registered the authority of operation camera.
If the authority of operation camera has been registered in certain application, illustrate that this application can call camera.For the operating system with open platform, as long as any application can operate the authority of camera based on this operating system to described operating system registration when exploitation.That is to say that the authority of operation camera has been registered in certain application, then this application just may operate camera, and no matter this application is legal or illegal.
Therefore, in embodiments of the present invention, as long as scope check unit 403 detects the authority that the stack top process has been registered the operation camera, in order to guarantee the personal secrets of camera, also need validity checking unit 404 to determine further according to blacklist and/or white list whether the stack top process is legal.
Certainly, if certain uses the authority of registration operation camera, then this application can not called camera, that is to say operation that can the executable operations camera.Therefore, if scope check unit 403 detects the authority that the stack top process is not registered the operation camera, can let slip this process, namely this process not intervened, make its normal operation.
Need to prove that above-mentioned blacklist and/or white list need to set up in advance, and can be kept at intelligent television this locality, also can be kept on the server.
For this reason, a kind of preferred implementation of above-mentioned validity checking unit 404 can comprise: local subelement and/or the long-range inspection subelement of checking.Wherein:
The described local subelement that checks checks for utilizing local built-in blacklist and/or white list to carry out this locality, determines whether described stack top process is legal;
Described long-range inspection subelement is used for utilizing blacklist and/or white list on the server to carry out long-range inspection, determines whether described stack top process is legal.
Need to prove, include only in validity checking unit 404 in the situation of described local inspection subelement, local built-in blacklist and/or white list need to server on up-to-date blacklist and/or white list keep synchronously, in a single day blacklist on the server and/or white list have renewal, then real-time synchronization is local to intelligent television, the concrete method of synchronization can adopt intelligent television request mode or server active push mode, and this embodiment of the invention is not done restriction.
Need to prove in addition, comprise simultaneously in validity checking unit 404 in the situation of described local inspection subelement and described long-range inspection subelement, when the stack top process is carried out validity checking, also can check by this locality whether local built-in blacklist and/or the white list of subelement inspection is latest edition first, such as, its version information is uploaded to server, and server returns corresponding information to intelligent television.If latest edition is then only carried out this locality inspection, otherwise, by described long-range inspection subelement the relevant information of described stack top process is uploaded onto the server again and carry out long-range inspection.
A telephotography of the present invention guard system, carry the application stack tabulation corresponding to application program of current operation of the intelligent television of operating system by Real-Time Monitoring, to using the stack top process in the stack tabulation, check whether it has registered the authority of operation camera, if registered the authority of operation camera, then further determine according to blacklist and/or white list whether described stack top process is legal, if described stack top process is illegal, then stop described stack top process operation.Realized thus monitoring that user's camera is called effectively having prevented the privacy of user leakage.
Because the use of camera can have dual mode: a kind of is that the camera that directly creates is used, and another is that other application call camera is used.
Therefore, the potential safety hazard of bringing for fear of other application call camera, in embodiments of the present invention, described process acquiring unit 402 also is used for after described validity checking unit 404 determines that described stack top process is legal, obtains other process successively from described application stack tabulation.
Correspondingly, described validity checking unit 404 also is used for determining according to described blacklist and/or white list whether other process that described process acquiring unit 402 obtains is legal.
Correspondingly, described prevention unit 405 also is used for after described validity checking unit 404 determines that described other process is illegal, stops described other process operation.
As seen, by to using the inspection of non-stack top process in the stack tabulation, further guaranteed the fail safe that the different modes camera is used.
As shown in Figure 5, be another structural representation of an according to an embodiment of the invention telephotography guard system.
From embodiment illustrated in fig. 4 different be that in this embodiment, described system also comprises:
The first Tip element 501 when being used for can't determining in described validity checking unit 404 that described stack top process or described other process be whether legal, carries out suspicious program prompts to the user.
Such as, the first Tip element 501 specifically can the prompting user current process have the purpose of operation camera, and ejects dialog box, so that whether user selection uses camera.
Correspondingly, described system also further comprises: command reception unit 502 and operation unit 503.Wherein: described command reception unit 502 is used for receiving the instruction whether user selection uses camera; Described operation unit 503 is used for moving described stack top process or described other process after described command reception unit 502 receives the instruction of user selection use camera.
Correspondingly, described prevention unit 405 also is used for stoping described stack top process or described other process operation after described command reception unit 502 receives the instruction that user selection do not use camera.
