Abstract
The invention discloses an anti-screenshot technology-based file data protection method. On the premise of no influence on the normal use of a user, a screen of a file window opened by a specific protected process is prevented from being captured by combining the anti-screenshot technology with process technology, so that file content is protected from being stolen. The method comprises the following steps of: actively detecting screenshot behaviors of an application program; if the screen of file window opened by the specific protected process is captured, starting an anti-screenshot function and prohibiting all the screenshot behaviors; and if the captured window is not the window opened by the specific protected process, not starting the anti-screenshot function and performing normal screenshot behaviors. According to the technical scheme of the invention, the screenshot action of the application program can be captured accurately; anti-screenshot action is performed pertinently; the screen of the file window opened by the specific protected process is protected from being captured; the file content is prevented from being leaked; and the screenshot action of a file window opened by a non-protected process is not influenced.
Description
Technical field
The present invention relates to field of computer technology, relate in particular in the Windows security of system product file data guard method by anti-screenshotss technology.
Background technology
Anti-screenshotss technology is a kind of anti-auxiliary security function items of divulging a secret, and the on-screen displays that prevents confidential information is intercepted the back and divulges a secret with image mode.Classical inverse screenshotss technology can realize by following technological means basically: the forbidding keyboard prevents to start the screenshotss function by hot key; Forbid moving the executable file of all operations, prevent to start screenshotss software; Allow the program window that oneself moves maximize, prevent screenshotss software switch window screenshotss; Use obtain application programming interfaces technology or graphics driver technology to the screen screenshotss behavior monitor.
But classical inverse screenshotss technology all exists certain defective, can not forbid directly starting the screenshotss function at software window as the forbidding keyboard; Forbid that the executable file that moves all nonsystematic users can cause the user can not carry out other operation behaviors; Allow the program window that oneself moves maximize the behavior that can not stop the AutoBackground screenshotss; Because of the application programming interfaces that screenshotss software uses also can be manipulated by other Windows, so only use obtain application programming interfaces technology to the screen screenshotss behavior monitor and can not guarantee the accuracy monitored, simultaneously, in case use this software, all screenshotss behaviors all will be under an embargo, and in the practical application, not all screenshotss behavior all is to be prohibited.
The present invention combines anti-screenshotss technology and process technology, carries out anti-screenshotss targetedly, mainly is to prevent by being that means are taken confidential information out of with screenshotss, is not to be purpose to stop user's screenshotss.
Summary of the invention
The objective of the invention is to propose a kind of file data guard method based on anti-screenshotss technology; do not influencing under the normal prerequisite of using of user; anti-screenshotss technology is combined with the process technology; the anti-screenshotss of opening for specific protected process of file window, thus reach the effect that the protected file content is not stolen.
For reaching this purpose, the present invention by the following technical solutions:
A kind of file data guard method based on anti-screenshotss technology may further comprise the steps:
A, initiatively detect the screenshotss action of application program, all executable application programs that use program of the present invention to monitor on one's own initiative to move on the current computer, the action of watchdog routine has judged whether the screenshotss action.
B, catch the screenshotss action of screenshotss software application.
C, judge whether this screenshotss behavior cuts full frame behavior.Judge by correlation parameters such as application programming interfaces whether this screenshotss behavior cuts full frame behavior, if this screenshotss behavior is to cut full frame behavior, go to step D, if this screenshotss behavior is not the full frame behavior that cuts, but the behavior that cuts active window goes to step e.
D, enumerate the file window of opening in the desktop.
E, catch the file activity window that sectional drawing software is cut.
F, obtain the process of the window that opens file.If cut full frame behavior, by enumerating all file windows of opening of desktop, obtain the process that all open window, if cut the active window behavior,, and then obtain the process of opening window by this active window.
G, whether there is protected process to open window, judges whether shielded process of the process that gets access to.If protected process is arranged, go to step H, if there is not protected process, go to step I.
H, the anti-screenshotss function of startup are forbidden screenshotss.If shielded process is arranged, then start anti-screenshotss function, forbid the screenshotss operation.
I, do not start anti-screenshotss function, allow screenshotss.If there is not shielded process, then do not start anti-screenshotss function, allow the screenshotss operation.
Adopted technical scheme of the present invention; anti-screenshotss technology is combined with the process technology; whether the process of accurately judging the window that opens file is protected, and the file of protecting protected process to open is not targetedly stolen by the mode with screenshotss by anti-screenshotss technique guarantee file content.The file window of non-protected process not being opened simultaneously carries out anti-screenshotss control, does not influence the user and normally uses screenshotss software.
Description of drawings
Figure below is for the control flow chart of screenshotss behavior in the specific embodiment of the invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
The main thought of technical solution of the present invention is by initiatively detecting the sectional drawing behavior of application program, in conjunction with parameters such as application programming interfaces correlated characteristics, judges that this sectional drawing behavior is to cut full frame or section active window behavior.To obtain application programming interfaces and identification trusted process two kinds of technological means combine, judge whether all windows or this active window in full frame is the window that protected process is opened, if, anti-screenshotss function on, if not, normal screenshotss.
Figure below is for the control flow chart of screenshotss behavior in the specific embodiment of the invention.As shown in the figure, this control flow may further comprise the steps:
Step 1, program begin.
Step 4, judge whether this screenshotss behavior cuts full frame behavior.Judge by correlation parameters such as application programming interfaces whether this screenshotss behavior cuts full frame behavior, if this screenshotss behavior is to cut full frame behavior, go to step 5, if this screenshotss behavior is not the full frame behavior that cuts, but the behavior that cuts active window goes to step 6.
Step 6, catch the file activity window that sectional drawing software is cut.
Step 9, the anti-screenshotss function of startup are forbidden screenshotss.If shielded process is arranged, then start anti-screenshotss function, forbid the screenshotss operation.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
