Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without any creative effort belong to the protection scope of the present application.
The tracing method based on the webpage watermark provided by the embodiment of the invention can be applied to a server. Different from the access control and audit technology of a server in the prior art, the tracing method based on the webpage watermark converts each DIV label in the webpage into various different DIV labels by adjusting HyperText Markup Language (HTML) in the webpage, such as attribute information of width, height, margin and the like of Division (DIV) labels, wherein the differences are embodied in the positions and sizes of the DIV labels to form the DIV labels to be embedded with the watermark information, and ensures that the webpage displayed to an internal user can uniquely identify the user, so that the internal user can be found by leaking the webpage content in the form of pictures. The form of the picture can be obtained by a screen capture mode of the user equipment. DIV tags, also known as separation marks. The function is to set the placing positions of characters, pictures, tables and the like on the current webpage.
It is understood that the HTML tag of the present application may be a format tag such as a directory listing DIR tag, a definition listing DL tag, an option listing MENU tag, or the like, in addition to the DIV tag listed above.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The following description will be made in detail by taking an example in which HTML tags are DIV tags.
Fig. 1A is a schematic flowchart of a tracing method based on a web watermark according to an embodiment of the present invention. As shown in fig. 1A, the execution subject of the method is a server, and the method may include:
and step 110, acquiring the published webpage picture carrying the watermark information.
Before executing this step, the server needs to generate a correspondence between the web page and the ordered DIV tag embedded with the watermark information, as shown in fig. 1B, the method may include:
and step 11, receiving a login request of an internal user for logging in the current webpage.
The login request includes user information, which may include an identification of the user, an identity of the unit, an IP address of the user, and a current timestamp.
And step 12, carrying out watermark encryption on the user information to obtain the watermark information of the user on the current webpage.
The server carries out watermark encryption on the user information according to the digital certificate applied in advance to obtain the watermark information of the user on the current webpage, and the watermark information can uniquely identify the login user. The server can convert the user information into a binary bit string, and then based on the digital certificate, the watermark encryption is performed on the binary bit string to obtain the binary bit string in the form of a ciphertext, namely watermark information.
And step 13, acquiring a first preset number of DIV labels in the current webpage, wherein the DIV labels are sequentially divided DIV labels to be embedded with watermark information.
When the current webpage is logged in for the first time, the server needs to acquire a first preset number of DIV labels to be embedded with watermark information in the current webpage.
Specifically, the server obtains attribute information of an original DIV tag of the current web page, where each web page may include multiple DIV tags, and each DIV tag has a corresponding sequence number, for example, the sequence numbers of three different DIV tags may be respectively denoted as DIV1, DIV2, and DIV 3.
And sequentially adjusting a second preset number of attribute information in the original DIV label, wherein the adjusted DIV label comprises a correspondingly adjusted coding sequence. Taking the second preset number as M as an example, sequentially adjusting the width, height, margin and the like of each original DIV label to embody the size and position of the DIV label, and obtaining 2MA code sequence, the width of the code sequence is M. When M is 2 and the adjusted attribute information is width (weight) and height (height), the coding sequence combinations of the adjusted DIV tags are (weight +0, height +0), (weight + delta w variation, height +0), (weight +0, height + delta h variation) and (weight + delta w variation, height + delta h variation), a first preset number of adjusted DIV tags meeting preset display conditions are selected from the adjusted DIV tags to serve as the DIV tags in which watermark information is to be embedded, and the preset display conditions are the influences of no display effect among the adjusted DIV tags when the current webpage is displayed. And then sequencing the DIV labels with the first preset number of to-be-embedded watermark information according to the sequence number of each DIV label to obtain the ordered DIV labels with the first preset number of to-be-embedded watermark information.
The server takes the webpage as a unit, stores the sequential DIV label serial numbers of the first preset number of the to-be-embedded watermark information selected in each webpage, the second preset number of the coded sequences corresponding to each sequential DIV label and the variable quantity of the attribute information, and establishes a label attribute coding library.
Optionally, in order to be able to quickly identify the variation of the adjusted DIV tag and the corresponding original DIV tag, the accuracy of tracing is improved, after the attribute information of the original DIV tag of the current webpage is obtained, the server may select the original DIV tag to be adjusted according to the attribute value of the attribute information of the original DIV tag, specifically: and selecting other original DIV labels after the original DIV label with the maximum attribute value is deleted. For example, the server sorts each original DIV label in each webpage from large to small according to the original product value of width and height, and since the adjusted variation of the original DIV label corresponding to the maximum product value is difficult to identify, watermark information is not embedded in such DIV label, the DIV label corresponding to the maximum product value is skipped, and adjustment is performed from the next DIV label.
When the current webpage is not logged in for the first time, the server acquires a first preset number of ordered DIV labels to be embedded with watermark information in the current webpage from the label attribute coding library according to the network identification of the current webpage.
And step 14, embedding the watermark information into a first preset number of ordered DIV labels in which the watermark information is to be embedded, and generating the ordered DIV labels in which the watermark information is embedded in the current webpage.
After a first preset number of ordered DIV labels in which watermark information is to be embedded are selected, the watermark information is embedded into the ordered DIV labels in which the watermark information is to be embedded. Each ordered DIV label to be embedded with watermark information can be embedded with a second preset number of bit numbers. The number of bits that each web page can be embedded is the product of the first preset number and the second preset number.
Specifically, binary bit strings in a ciphertext form are grouped, wherein each group comprises a second preset number of binary bit numbers; and sequentially embedding a second preset number of binary bit numbers into the ordered DIV labels to be embedded with the watermark information according to the arrangement sequence of the DIV labels.
It should be noted that, if there are groups with a bit number less than the second preset number, the groups may be padded with preset codes, otherwise, if there are remaining bit numbers after the grouping of the first preset number is completed, the remaining bit numbers are deleted.
Returning to step 110, after discovering the published web page picture containing the internal information on the internet, the internal manager uploads the picture to the server of the application, so that the server obtains the published web page picture carrying the watermark information.
And step 120, matching the web page picture with the stored complete web page to obtain the web page identification of the complete web page corresponding to the web page picture.
The server can search a webpage library storing complete webpages in an image processing mode to obtain webpage identifiers of the complete webpages identical to the obtained webpage pictures, or obtain webpage identifiers of the complete webpages containing the obtained webpage pictures. The web page identification may be a web address of the web page. It can be understood that the web page identifier of the complete web page corresponding to the web page picture can also be obtained in a manual identification mode.
Step 130, based on the web page identifier and the stored tag attribute code library, obtaining a first preset number of ordered DIV tags embedded with watermark information of the complete web page.
The server acquires a first preset number of ordered DIV labels embedded with watermark information corresponding to the webpage identifier from a label attribute coding library based on the webpage identifier, wherein the ordered DIV labels are DIV labels ordered according to DIV label serial numbers.
And 140, extracting the watermark information in the first preset number of the orderly DIV labels embedded with the watermark information.
The server may extract watermark information from the obtained first preset number of ordered DIV tags in which the watermark information is embedded, that is, the watermark information is a set of partial watermark information embedded in each ordered DIV tag. The server can extract the watermark information by comparing a first preset number of ordered DIV labels embedded with the watermark information with corresponding original DIV labels to obtain a change amount.
Or, the server may also directly obtain the change amount between the ordered DIV tags embedded with the watermark information in the first preset number and the corresponding original DIV tags from the established tag attribute coding library.
And 150, decrypting the watermark information to obtain the user information of the published webpage picture.
And the server decrypts the watermark information to obtain the user information of the published webpage picture.
It can be understood that the method described in the present application is not only applicable to the above-listed DIV tags, but also applicable to format tags such as directory list DIR tags, definition list DL tags, option list MENU tags, and the like, and the details of the embodiment of the present invention are not repeated herein.
Fig. 2 is a schematic flowchart of another tracing method based on web page watermarking according to an embodiment of the present invention. As shown in fig. 2, the execution subject of the method is a server, and the method may include:
step 201, receiving a login request of an internal user, wherein the login request comprises user information.
Step 202, performing watermark encryption on the user information to obtain watermark information of the user on the current webpage. When the internal user is the first login, step 203 is executed, and when the internal user is not the first login, step 208 is executed.
And carrying out watermark encryption on the user information according to the digital certificate applied in advance to obtain the watermark information of the user on the current webpage.
And step 203, acquiring the attribute information of the original DIV label of the current webpage.
And 204, sequentially adjusting a second preset number of attribute information in the original DIV label to obtain the adjusted DIV label.
The adjusted DIV tag includes the corresponding coding sequence.
And step 205, selecting a first preset number of DIV labels which meet preset display conditions and are to be embedded with watermark information from the adjusted DIV labels.
And step 206, sequencing the DIV labels with the first preset number of watermark information to be embedded according to the sequence numbers of the DIV labels to obtain corresponding ordered DIV labels.
Step 207, establishing a tag attribute code library, and then executing step 209.
And storing the ordered DIV label serial numbers of the first preset number of pieces of watermark information to be embedded, the second preset number of coded sequences corresponding to each label and the information of the variable quantity of the adjusted attribute information.
Step 208, according to the network identifier of the current webpage, obtaining a first preset number of ordered DIV tags to be embedded with watermark information from the tag attribute coding library, and then executing step 209.
And step 209, embedding the watermark information into the ordered DIV label to be embedded with the watermark information.
And step 210, acquiring the published webpage picture carrying the watermark information.
And step 211, matching the web page picture with the stored complete web page to obtain the web page identifier of the complete web page corresponding to the web page picture.
And step 212, acquiring a first preset number of ordered DIV labels embedded with watermark information of the complete webpage based on the webpage identification.
And step 213, extracting the watermark information in the ordered DIV label.
And 214, decrypting the watermark information to obtain the user information of the published webpage picture.
