Abstract
The invention belongs to the technical field of computer information safety, in particular to a screen capture control method. The screen capture prevention method based on program windows includes the following steps of firstly, conducting API calling tracking on operation of all application software, judging whether the operation is screen capture operation or not, and conducting no processing if the operation is not the screen capture operation; secondly, judging whether the windows of protected files exists in all the current windows on the desktop or not if the operation is the screen capture operation, and conducting no processing if the windows of the protected files do not exist in the current windows on the desktop; thirdly, allowing the application software to continue executing the screen capture operation so as to obtain a screenshot of the desktop if the windows of the protected files exist in all the current windows on the desktop, redrawing the screenshot of the desktop, shielding the windows of all the protected files so as to obtain a picture in which the windows of the protected files are blackened and the windows of other files are normally displayed, and replacing the screenshot with the picture. By means of the method, third-party software can be effectively prevented from shooting the picture of the windows of the protected files, and meanwhile operation habits of a user and the normal screenshot, obtained through the third-party software, of the windows of the unprotected files are reserved.
Description
Technical field
The invention belongs to field of computer information security technical field, particularly a kind of method of controlling screenshotss.
Background technology
In computer document safeguard protection field; the research direction of data protection be mostly placed on document anti-steal and be stolen after can not be cracked; and ignored confidential document by legal opening after; the screenshotss function that its content carries by system screenshotss function or third party software is stolen with picture form, and this falls short of success for lack of final effort safety prevention measure.For this problem, some securing software carries out anti-screenshotss operation by quiescing system screenshotss, but cannot prevent that the person of stealing secret information is by third party software screenshotss.
Summary of the invention
The object of the invention is: provide one to overcome existing anti-screenshotss technical disadvantages, do not affecting under the prerequisite of user operation habits, ensure that secret window data can not be intercepted by screenshotss software, but still allow the method that the content of unclassified window is intercepted.
Technical scheme of the present invention is: a kind of anti-screenshotss method based on program window, comprises the following steps:
A, the operation of all application software is carried out to API Calls tracking, judge whether this operation is screenshotss operations; If not screenshotss operation, do not do any processing, this application software operation continues to carry out; If B step is carried out in screenshotss operation;
B, judgement are when whether there being the window of agent-protected file in all windows of front desktop; If there is no, do not do any processing, this application software continues to carry out screenshotss operation; Otherwise, carry out C step;
C, allow this application software to continue to carry out screenshotss operation, obtain desktop sectional drawing; Desktop sectional drawing is redrawn, the window of all agent-protected files is wherein shielded, obtain the window of agent-protected file by the normal picture showing of the window of blacking, other file, replace described desktop sectional drawing.
The present invention can effectively prevent that third party software from intercepting the window of agent-protected file, retains user operation habits simultaneously, and the normal screenshotss of third party software to non-agent-protected file window.
Brief description of the drawings
Accompanying drawing 1 is process flow diagram of the present invention.
Embodiment
Referring to accompanying drawing 1, a kind of anti-screenshotss method based on program window, comprises the following steps:
A, the operation of all application software is carried out to API Calls tracking, judge whether this operation is screenshotss operations; If not screenshotss operation, do not do any processing, this application software operation continues to carry out; If B step is carried out in screenshotss operation;
B, judgement are when whether there being the window of agent-protected file in all windows of front desktop; If there is no, do not do any processing, this application software continues to carry out screenshotss operation; Otherwise, carry out C step;
C, allow this application software to continue to carry out screenshotss operation, obtain desktop sectional drawing; Desktop sectional drawing is redrawn, the window of all agent-protected files is wherein shielded, obtain the window of agent-protected file by the normal picture showing of the window of blacking, other file, replace described desktop sectional drawing.
Claims (1)
