Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, the guard method of display data on the screen of the present invention, specifically comprises following flow process:
1, first user arranges the trigger mechanism of all kinds of confidential data (namely needing the data protected) and on-screen data protection system, and when accessing confidential data, on-screen data protection system will automatic and confidential data synchronous operation.
The trigger mechanism of confidential data and on-screen data protection system can adopt technology known in the art to realize, such as but not limited to hook (Hook) technology.
Setting screen data protection system want the information of generating watermark, comprise the data, particularly MAC Address such as computer name, user name, data access time, IP address, MAC Address and there is uniqueness, can accurately distinguish each user by this type of information.
Watermark form is set, comprises written form or graphic form; Wherein, current user information is directly illustrated on screen with written form by text watermark.When user accesses confidential data, on-screen data protection system can be triggered and generate on-screen data protection watermark, current user information is presented on screen with the tiling of text watermark form; Word message is translucent display, does not affect the normal use of other guide on screen.Figure watermark current user information is converted to the unreadable figure such as Quick Response Code or bar code, and then to tile on screen display in translucent mode, figure watermark can not affect the use of other guide on screen equally.Figure watermark has stronger robustness, even if distorted by malicious user part, also can successfully recover the current user information be hidden in figure.
