Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a traceable implicit watermarking method according to an exemplary embodiment, and referring to fig. 1, the method includes the following steps:
s1: and selecting at least one position to be added with the watermark on a software interface to be added with the watermark.
Specifically, a software interface to be added with the watermark is analyzed, and at least one position suitable for embedding the watermark to be added is selected from the software interface to be added with the watermark.
As a preferred implementation manner, in the embodiment of the present invention, the following positions on a software interface to be watermarked may be selected as positions to be watermarked:
selecting the background pattern of the software interface as a position to be added with the watermark; and/or the presence of a gas in the gas,
selecting a button on the software interface as a position to be added with the watermark; and/or the presence of a gas in the gas,
and selecting an icon on the software interface as a position to be added with the watermark.
It should be noted here that the positions to be watermarked in the embodiment of the present invention are not limited to the above three types, and may be any positions on a software interface.
S2: and correspondingly constructing at least one implicit watermark pattern aiming at the position to be added with the watermark, wherein the implicit watermark pattern comprises the information of the software user.
Specifically, at least one implicit watermark pattern is constructed corresponding to the selected position to be added with the watermark, namely, after the preset numbers, letters, other characters and the like are subjected to graphical design, a watermark pattern conforming to the software interface scene is generated, and the implicit watermark pattern is displayed in combination with the scene in the software interface and is not perceived by a user.
As a preferred implementation manner, in the embodiment of the present invention, information of the software user is extracted, and an implicit watermark pattern is generated after the information of the software user is subjected to a graphical processing.
As a preferred implementation manner, in an embodiment of the present invention, the information of the software user includes job number numbers of the user, and the generating the implicit watermark pattern by performing the graphical processing on the information of the software user includes:
carrying out different graphical processing on the numbers 0 to 9 to respectively generate different first graphs;
and rearranging and combining the first graphs according to the arrangement sequence of the job number numbers of the user to generate an implicit watermark pattern corresponding to the job number numbers of the user.
As a preferred implementation manner, in the embodiment of the present invention, the performing graphical processing on the information of the software user further includes:
presetting a general second graph, recombining the first graph according to the arrangement sequence of the job number numbers of the user, and supplementing the second graph into the rearranged and combined image to generate an implicit watermark pattern corresponding to the job number numbers of the user. It should be noted that the second graphic can be supplemented at a specific position (such as the foremost or rearmost of the rearranged and combined images) or at any position according to the requirement.
For example, in software for scanning code to purchase goods, the implicit watermark pattern can be designed into a two-dimensional code mode. Assuming that the job number of the user is a combination of 8 digits, different graphics processing is first performed on the digits 0 to 9 to generate different first graphics, respectively. And then rearranging and combining the corresponding first images according to the arrangement sequence of the job number numbers of the user, and arranging the first images into a two-dimensional code pattern, namely arranging the first images corresponding to the job number numbers of the user according to a 3x3 arrangement matrix to generate a combined image similar to a nine-square grid. Because the work number of the user is only 8, one spare graph position is added, and the position of the right lower corner of the two-dimensional code icon has an irregular graph pattern, a conventional universal graph (namely a second graph) is designed to be placed at the last position of the nine-square grid graph for combination, so that the generated integral pattern of the implicit watermark pattern is very similar to the two-dimensional code icon, and the implicit watermark pattern can not be distinguished by naked eyes basically. Or, the generated implicit watermark pattern is adjusted according to the size of a Button (Button) on a software interface, and then is added to the Button to be made into a two-dimensional code Button.
When a user screenshot is shared by others, the implicit watermark pattern of the two-dimension code in the page can be shared out at the same time, and the user can think that the screenshot is only Button of the two-dimension code, so that the user himself cannot feel the screenshot. When the manager finds that someone obtains the screenshot of the commodity price, the user sharing the picture can be traced back through the two-dimensional code implicit watermark pattern in the screenshot, and therefore the manager can complete the whole privacy disclosure tracing process conveniently.
S3: and embedding the implicit watermark pattern into the position to be added with the watermark to obtain an interface embedded with the implicit watermark.
Specifically, the implicit watermark pattern is hidden in the existing scene elements of the software interface, cannot be recognized by a common user, and is easy and convenient for a developer to recognize. Before privacy disclosure happens, the time of several hours or even several days is needed for tracing, and the technical scheme provided by the embodiment of the invention can realize tracing only in 1 to 2 minutes at the fastest speed. The positions to be added with watermarks in the software interface can include a plurality of positions, and the implicit watermark pattern is embedded in different positions to be added with watermarks in different ways, as shown below:
if the background pattern of the software interface is used as the position to be added with the watermark, the color of the implicit watermark pattern is adjusted according to the color of the background pattern, and the adjusted implicit watermark pattern is embedded into the background pattern, so that the implicit watermark pattern is hidden in the background pattern, even if the implicit watermark pattern and the background pattern are fused into a whole. For example, if the color of the background pattern is a pure color value # F8F8, the color value of the implicit watermark pattern can be adjusted to # F6F6, and the implicit watermark pattern can be embedded in the background pattern and cannot be recognized by the user with the naked eye, but can be easily read by a machine.
And if the button on the software interface is taken as the position to be added with the watermark, the size of the implicit watermark pattern is adjusted according to the size of the button, and then the implicit watermark pattern is added on the button. For example, the job number of the user is imaged to generate an implicit watermark pattern of a two-dimensional code pattern, and the implicit watermark pattern is adjusted in size and then embedded into the button position of the software interface.
If the icon on the software interface is used as the position to be added with the watermark, the implicit watermark pattern is hidden in the icon after being adjusted according to the pattern style of the icon and cannot be identified by a common user, and the implicit watermark pattern contains information of a login user, so that people with privacy disclosure can be easily found through the implicit watermark pattern as long as the privacy disclosure is carried out. During specific operation, the style of the implicit watermark pattern can be designed by combining one icon or a plurality of icons.
Fig. 2 is a schematic structural diagram illustrating a traceable implicit watermarking apparatus according to an exemplary embodiment, and referring to fig. 2, the apparatus includes:
the position acquisition module is used for selecting at least one position to be added with the watermark on a software interface to be added with the watermark;

and the watermark embedding module is used for embedding the implicit watermark pattern into the position to be added with the watermark to obtain an interface embedded with the implicit watermark.
As a preferred implementation manner, in the embodiment of the present invention, the position obtaining module is specifically configured to:

selecting a button on the software interface as a position to be added with the watermark; and/or the presence of a gas in the gas,
