step a, converting a document containing key information (the key information is used for identifying a user, the key information can be a staff name, or the key information can be a staff number) into an image in a preset format, for example, the image in the preset format can be a base64 image.
Note that the base64 image is a representation method for representing binary data based on 64 printable characters. Modern browsers support web pages to directly use base64 encoded strings for picture display.
Step b: and dynamically creating a watermark DOM and setting a corresponding inline style. Creating a watermark on a page through a Javascript script, and adding data such as a style and the like to the watermark; the style attributes involved in the process comprise background, width, height, layout mode and the like, and finally the watermark is added to the page and displayed; wherein, DOM is the document object type, and W3C organizes the recommended standard programming interface for processing extensible markup language, which is used for Javascript operation web pages.
And c, removing the watermark style name by using a Javascript method remove Attribute ("class"), preventing an external user from tampering the watermark element by using a DOM (document object model) related API (application program interface), and ensuring that the watermark is not changed before and after the movement.
And d, judging whether the browser supports the Mutation Observer, if the current browser does not support the API, dynamically loading the compatible code, and actively realizing the API for the browser.
And e, copying and backing up the current watermark DOM to prevent the watermark from being damaged and then being incapable of being recovered due to tampering.
Step f, creating a Mutation Observer object, monitoring the DOM change of the whole page, judging that the changed DOM is the current watermark, and replacing the current page watermark by using a backup if the DOM is a modification action; if the page is deleted, the backup is directly added to the page.
And g, when the operation is finished, notifying the user to support the user to perform subsequent processing on the behavior, for example, reporting the environment information to a third party so as to facilitate the third party to collect the relevant environment data.
It should be noted that the watermark technology in the method for preventing the webpage watermark from being tampered provided by the embodiment of the present invention is an information hiding technology, and the watermark technology is widely applied in the fields of copyright, encryption, transmission, and the like. With the increasing importance on enterprise information security, the watermark technology is also developed, and the method for preventing the webpage watermark from being tampered provided by the embodiment of the invention achieves the purpose that the webpage watermark cannot be tampered through the Mutation Observer technology.
The Mutation Observer is the DOM Level3 Events specification, which is not implemented on older versions of browsers, and the API functions to provide the ability to monitor changes made to the DOM tree.
The embodiment of the invention provides a method for preventing webpage watermark from being tampered, which monitors the change condition of a watermark document object model of a current webpage; according to the change condition of the watermark document object model of the current webpage, the watermark tampering operation on the current webpage is identified, and when the watermark tampering operation is identified, the watermark document object model which is backed up in advance is used for replacing or adding, so that the phenomenon that the webpage watermark is tampered is avoided.

Such a propagated data signal may take many forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: electrical wires, optical cables, RF (radio frequency), etc., or any suitable combination of the foregoing.
The computer readable medium may be embodied in the electronic device; or may exist separately without being assembled into the electronic device.
The computer readable medium carries one or more programs which, when executed by the electronic device, cause the electronic device to: the method can monitor the change condition of the watermark document object model of the current webpage; according to the change condition of the watermark document object model of the current webpage, the watermark tampering operation on the current webpage is identified, and when the watermark tampering operation is identified, the watermark document object model which is backed up in advance is used for replacing or adding, so that the phenomenon that the webpage watermark is tampered is avoided. Alternatively, the computer readable medium carries one or more programs which, when executed by the electronic device, cause the electronic device to: the method can monitor the change condition of the watermark document object model of the current webpage; according to the change condition of the watermark document object model of the current webpage, the watermark tampering operation on the current webpage is identified, and when the watermark tampering operation is identified, the watermark document object model which is backed up in advance is used for replacing or adding, so that the phenomenon that the webpage watermark is tampered is avoided.
Computer program code for carrying out operations for aspects of the present disclosure may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C + +, and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any type of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet service provider).
The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The units described in the embodiments of the present disclosure may be implemented by software or hardware. Where the name of an element does not in some cases constitute a limitation on the element itself.
