APPARATUS THEREOF
BACKGROUND OF THE INVENTION
Technical Field [0001] The present invention relates to the technical field of computers, and more particularly to a backtraceable invisible watermark adding method and an apparatus thereof.
Description of Related Art
[0002] Generally, for protecting sensitive privacy information, it is a common practice that a brand adds its exclusive watermarks into images or interfaces directly or indirectly, so as to prevent unauthorized use. In the event of unauthorized use or dissemination, the watermark can be helpful to identify the responsible disseminator. Without such a watermark, the responsible disseminator can only be identified through its user name. If the dissemination was made anonymously, more investigation has to be conducted by specialists at the back end.
[0003] However, adding such a watermark directly in the content can form interference with information display and thus is adverse in terms of esthetics. In addition, a user anyway wanting to avoid the tracking mechanism of the watermark may electronically remove the watermark. Even if the brand can track back to the initial disseminator through IP
search, the process is time- and effort-consuming and costly. While the brand may use a watermark to carry a user ID so as to further deter a user from disseminating sensitive information, once the user removes the watermark in some manner before dissemination, it is still impossible for the brand to directly identify the information disseminator. In this case, to identify the initial disseminator, all involved parties have to be questioned or all Date Recue/Date Received 2022-06-21 involved IPs have to be checked, which process is also time- and effort-consuming and costly.

Date Recue/Date Received 2022-06-21 DETAILED DESCRIPTION OF THE INVENTION
[0043] To make the foregoing objectives, features, and advantages of the present invention clearer and more understandable, the following description will be directed to some embodiments as depicted in the accompanying drawings to detail the technical schemes disclosed in these embodiments. It is, however, to be understood that the embodiments referred herein are only a part of all possible embodiments and thus not exhaustive. Based on the embodiments of the present invention, all the other embodiments can be conceived without creative labor by people of ordinary skill in the art, and all these and other embodiments shall be encompassed in the scope of the present invention.
[0044] FIG. 1 is a flowchart of a backtraceable invisible watermark adding method according to one exemplary embodiment of the present invention. As show, the method comprises the following steps.
[0045] Si: in a software interface to which a watermark is to be added, selecting at least one location for the watermark to be placed.
[0046] Specifically, the software interface for the watermark to be added is analyzed so as to properly select at least one location for the watermark to be placed in the software interface for the watermark to be added.
[0047] As a more preferred implementation, in the embodiment of the present invention, one of the following locations may be selected in the software interface for the watermark to be added as the location for the watermark to be placed:
[0048] selecting a background pattern of the software interface as the location for the watermark to be placed; and/or,
[0049] selecting a button in the software interface as the location for the watermark to be placed;
Date Recue/Date Received 2022-06-21 and/or,
Date Recue/Date Received 2022-06-21 and/or,
[0050] selecting an icon in the software interface as the location for the watermark to be placed.
[0051] It is to be noted herein that, in the embodiment of the present invention, the location for the watermark to be placed is not limited to the foregoing three alternatives and may be any location in the software interface.
[0052] S2: for the location for the watermark to be placed, building at least one invisible watermark pattern correspondingly, wherein the invisible watermark pattern includes information of a software user.
[0053] Specifically, corresponding to the selected location for the watermark to be placed, at least one invisible watermark pattern is built. In particular, predetermined digits or letters or the like are graphically designed to generate a watermark form adapted to the scene elements of the software interface. The watermark form can be displayed together with the scene of the software interface in a manner that the watermark is unperceivable to users.
[0054] As a more preferred implementation, in the embodiment of the present invention, the information of the software user is first extracted and then graphed, so as to generate the invisible watermark pattern.
[0055] As a more preferred implementation, in the embodiment of the present invention, the information of the software user includes a worker identification number of the user, and the step of graphing the information of the software user so as to generate the invisible watermark pattern comprises:
[0056] graphing digits 0 through 9 differently, so as to generate different first images; and
[0057] according to a sequence of the digits of the worker identification number of the user, rearranging the first images, so as to generate the invisible watermark pattern Date Recue/Date Received 2022-06-21 corresponding to the digits of the worker identification number of the user.
[0058] As a more preferred implementation, in the embodiment of the present invention, the step of graphing the information of the software user further comprises:
[0059] predefining a second image for general use, rearranging the first images according to the sequence of the digits of the worker identification number of the user, and adding the second image into the rearranged images, so as to generate the invisible watermark pattern corresponding to the digits of the worker identification number of the user. It is to be noted herein that the second image may be added to a specific location according to practical needs (for example, as a prefix or a suffix of the rearranged images), or may be added at any other location.
[0060] For example, for a scan-and-shop software, the invisible watermark pattern of the present invention may be designed into the form of a two-dimensional code. Assuming that the worker identification number of a user is a combination of 8 digits, each of the digits is first graphed depending on which it is in 0 through 9, so as to generate different first images. Then according to the sequence of the digits in the worker identification number of the user, the corresponding first images are rearranged into the form of a two-dimensional code. To be specific, the first images corresponding to the digits in the worker identification number of the user are arranged into a 3x3 matrix, so as to generate a combined image like a nine-square combination. Since the worker identification number of the user has only 8 digits, there will be a void image location.
Because a two-dimensional code icon always includes an irregular image form at its lower right corner, an image for general use (i.e., the second image) may be designed and affixed to the nine-square combination images at the tail to join the combination, so that the generated invisible watermark pattern looks very similar to a two-dimensional code icon to the extent that the difference therebetween is basically unperceivable to naked eyes.
Alternatively, the generated invisible watermark pattern may be sized to a button in the software interface and then added to a button to form a two-dimensional code button.

Alternatively, the generated invisible watermark pattern may be sized to a button in the software interface and then added to a button to form a two-dimensional code button.
Date Recue/Date Received 2022-06-21
[0061] When a user screenshots a page and shares the image to others, the invisible watermark pattern in the two-dimensional code will be sent out simultaneously, and the user will think it as a button of the two-dimensional code without awareness that there is a watermark. When an administrator finds that someone hold the unauthorized screenshot image containing product prices, the administrator can track back to the user who shared this image through the invisible watermark pattern in the two-dimensional code in the screenshot image, thereby conducing privacy breach backtracking.
[0062] The step S3 is about embedding the invisible watermark pattern to the location for the watermark to be placed, so as to obtain the interface with the invisible watermark embedded therein.
[0063] Specifically, the invisible watermark pattern is such hidden in the existing scene of the scene of the software interface that it is unperceivable to users.
Nevertheless, the developer can easily recognize it. In the prior art, a backtracking process after a privacy breach can take hours or even days. By contrast, with the technical schemes of the embodiments of the present invention, such a process can be done in 1 to 2 minutes. In a software interface, there may be plural locations for the watermark to be placed. For different locations for the watermark to be placed, the invisible watermark pattern may be embedded in different ways as further described below.

In a software interface, there may be plural locations for the watermark to be placed. For different locations for the watermark to be placed, the invisible watermark pattern may be embedded in different ways as further described below.
[0064] If the background pattern of the software interface is taken as the location for the watermark to be placed, the color of the invisible watermark pattern is adjusted according to the color of the background pattern, and the adjusted invisible watermark pattern is embedded into the background pattern, so that the invisible watermark pattern is hidden in the background pattern to the extent that the invisible watermark pattern and the background pattern fit in each other. For example, the color of the background pattern is of a solid color value #F8F8F8, and the color of the invisible watermark pattern may be Date Recue/Date Received 2022-06-21 adjusted to #F6F6F6, so when the invisible watermark pattern is embedded into the background pattern, users cannot tell the two apart with their eyes, yet the watermark can be easily read by a machine.
[0065] If a button in software interface is taken as the location for the watermark to be placed, the invisible watermark pattern is sized to the button, and the invisible watermark pattern is added to the array of buttons. For example, the digits in the worker identification number of the user are graphed to generate an invisible watermark pattern in the form of a two-dimensional code, and properly sized before placed into a button location in the software interface.
[0066] If an icon in software interface is taken as the location for the watermark to be placed, the invisible watermark pattern is adapted to the pattern form of an icon, so that the invisible watermark pattern can be hidden in the icon and become unperceivable to general users.
The invisible watermark pattern carries the information of the registered user. Therefore, once the user involves privacy breach, he/she can be easily identified through the invisible watermark pattern. Therein, for practical implementations, the form of the invisible watermark pattern may be designed with one or more icons blended therein.
