Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
In order to protect a watermark in a web page and improve security of the web page, referring to fig. 1, fig. 1 is a flowchart of a watermark processing method provided in an embodiment of the present invention, where the method is applied to an electronic device, and the method may include the following steps:
s101: when the target watermark is detected to be added in the target webpage, the preset attribute information of the target watermark in the target webpage is obtained.
The preset attribute information is used for representing information calling of the target watermark in the target webpage.
S102: and converting the preset attribute information into target attribute information.
And the target attribute information and the preset attribute information have a preset corresponding relation.
S103: and monitoring the target attribute information to determine whether the target watermark is modified in the target webpage.
S104: and when the target watermark is determined to be modified in the target webpage, modifying the target watermark to be in an initial state.
The watermark processing method provided by the embodiment of the invention can convert the preset attribute information of the target watermark into the target attribute information, and can prevent a malicious user from acquiring the target attribute information of the target watermark and modifying the target watermark through the target attribute information because the malicious user cannot acquire the target attribute information. In addition, the target watermark can be modified to the initial state when the target watermark is detected to be modified, namely, the modification of the target watermark by a malicious user can be restored, the watermark in the webpage can be protected, and further, the safety of the webpage can be improved.
In step S101, the target webpage may be any webpage displayed by the electronic device, and the target watermark is any watermark added to the target webpage. The preset attribute information of the target watermark in the target webpage is used for representing the information call of the target watermark in the target webpage.
For example, the preset attribute information may include: identification information, style information and content information of the target watermark. The identification information of the target watermark is recorded with the watermark identification of the target watermark. The pattern information records a pattern of the target watermark, for example, a color, a shape, a size, a number, a display position, and the like of the target watermark. The content information records content of the target watermark, for example, text content, picture content of pictures, and the like.
In step S102, a DOM (Text Object Model) tree corresponding to the target web page includes a plurality of nodes, each node of the DOM tree corresponds to the page content of the target web page, the target watermark corresponds to one node (which may be referred to as a watermark node) of the DOM tree, and the watermark node is an HTML (Hyper Text Markup Language) source code corresponding to the target watermark. The watermark identification of the target watermark is the node identification of the watermark node.
The watermark identification in the preset attribute information is fixed characters such as a watermark and a logo, which are commonly used, when a malicious user modifies the target watermark, a watermark node (namely, an HTML source code corresponding to the target watermark) needs to be determined in a DOM tree in a target webpage through the watermark identification of the target watermark, and then the HTML source code corresponding to the target watermark is modified to modify the target watermark.
Therefore, in order to prevent a malicious user from determining the HTML source code corresponding to the target watermark, the preset attribute information may be converted into the target attribute information. In one implementation, the parameter value of the identification information in the preset attribute information may be modified to a target parameter value, so as to obtain target attribute information of the target watermark.
In one implementation, the electronic device may generate a random string based on a preset random algorithm, and then modify a parameter value of the identification information in the preset attribute information into the generated random string, where the watermark of the target watermark is identified as the random string (i.e., the target parameter value).
The random algorithm may be an algorithm for generating a random string, for example, a math random algorithm.
Based on the processing, a malicious user can not know the watermark identification of the target watermark, and can be prevented from determining the HTML source code corresponding to the target watermark through the fixed watermark identification and modifying the target watermark compared with the fixed watermark identification, so that the safety of the webpage can be improved.
In another way, the electronic device may calculate the MD5 value of a preset character (watermark, logo, etc.) based on MD5(Message Digest Algorithm 5). Furthermore, the electronic device may modify a parameter value of the identification information in the preset attribute information to the calculated MD5 value, where the watermark of the target watermark is identified as the MD5 value of the preset character.
Based on the above processing, when a technician needs to adjust the target watermark, the MD5 value of the preset character may be calculated, and the HTML source code whose node identifier is the MD5 value is determined in the DOM tree corresponding to the target webpage, that is, the HTML source code corresponding to the target watermark. Furthermore, technicians can modify HTML source codes corresponding to the target watermarks to adjust the target watermarks, so that malicious users can be prevented from modifying the target watermarks, and the technicians can conveniently adjust the target watermarks.
In an embodiment of the present invention, when a malicious user modifies a target watermark in a target web page, a developer tool page needs to be opened in the target web page first, and the target watermark is modified through the developer tool page. Therefore, in order to prevent the target watermark from being modified, the method may further comprise the steps of:
when the target event is monitored, preset information except for the developer tool page is displayed.
The target event represents that a user triggers a target control in a target webpage; the target controls represent controls for displaying the developer tools page based on the original configuration of the target web page.
In one implementation, in order to prevent a malicious user from entering a developer tool page, a target watermark is deleted or modified through the developer tool page, and a technician may unbind a corresponding relationship between a target event and a display developer tool page in an original configuration of a target web page and bind the target event and display preset information in the original configuration of the target web page, where the preset information is information other than the developer tool page. Furthermore, when the electronic device monitors the target event, the electronic device does not display the developer tool page but displays the preset information.
It can be understood that the preset information may be blank information, that is, a technician may modify the correspondence relationship to indicate that the target event points to the blank information. Accordingly, the electronic device may not respond to the target event, i.e., not display any other information, when it listens to the target event.
Or, the preset information may be a reminding message, that is, the technician may modify the correspondence to bind the target event with the display reminding message. Correspondingly, the electronic device can display the reminding message when monitoring the target event. For example, the electronic device may display a reminder message containing "prohibit opening of the developer tools page" content.
The target event represents that a user triggers a target control in a target webpage; the target controls represent controls for displaying the developer tools page based on the original configuration of the target web page. Illustratively, the target control may be the F12 button, and the target control may also be a "developer tools" button in the menu bar of the target web page.
In one implementation, when the target control is the F12 button, the electronic device may listen for a target event that the user triggers the F12 button through an eventtarget. For example, a keydown event, a keyup event, or a keyress event corresponding to the F12 key may be monitored, or a keydown event, a keyup event, or a keypress event corresponding to the F12 key may also be monitored at the same time, and when any one of the above events corresponding to the F12 key is monitored, it indicates that the user has triggered the F12 key, the electronic device may display the preset information.
In another implementation, when the target control is a "developer tool" button in a menu bar of the target web page, the electronic device may monitor a target event that the user triggers the "developer tool" button through a mouse by using an eventtarget. For example, a contextmenu event corresponding to the "developer tools" button may be monitored, and when the contextmenu event corresponding to the "developer tools" button is monitored, indicating that the user has triggered the "developer tools" button, the electronic device may display the preset information.
Based on the processing, the malicious user can be prevented from opening the developer tool page, and then the malicious user is prevented from deleting or modifying the target watermark in the target webpage through the developer tool page, so that the safety of the webpage can be further improved.
In step S103, if the user opens the developer tool page by other means, the user may delete or modify the target watermark through the developer tool page. Therefore, to further improve the security of the web page, the electronic device may detect whether the target watermark is modified.
In one embodiment of the present invention, referring to fig. 2, step S103 may include the steps of:
s1031: and detecting whether attribute information to be processed with a changed parameter value exists in the target attribute information recorded in the first HTML source code corresponding to the target watermark, and if so, executing step S1032.
S1032: it is determined that the target watermark is modified in the target web page.
In one implementation, if a malicious user modifies a target watermark, a parameter value of target attribute information of the target watermark may be changed, so that the electronic device may detect whether there is attribute information to be processed, of which the parameter value is changed, in the target attribute information recorded in the first HTML source code, so as to perform corresponding processing according to a detection result.
The first HTML source code is generated when the preset attribute information of the target watermark is converted into the target attribute information, and therefore the initial parameter value of the target attribute information of the target watermark is recorded in the first HTML source code. It is to be understood that the initial parameter value of the identification information in the target attribute information is the target parameter value in the foregoing embodiment.
If the current parameter value of any attribute information is not the initial parameter value, the parameter value of the attribute information can be determined to be changed, that is, the attribute information to be processed with the changed parameter value can be determined to exist, and the target watermark is modified in the target webpage.
In one embodiment of the present invention, referring to fig. 3, step S1031 may include the steps of:
s10311: monitoring whether a modified target field exists in a field corresponding to a parameter value of target attribute information in the first HTML source code through an element Observer Mutation Observer, if so, executing step S10312, and if not, executing step S10313.
S10312: and determining attribute information corresponding to the target field, wherein the attribute information is to-be-processed attribute information with changed parameter values.
S10313: and determining that the attribute information to be processed with the changed parameter value does not exist.
In one implementation, the electronic device may determine, through a document.getelementbyid (node is obtained by identification), a node (i.e., a watermark node) corresponding to the watermark identification of the target watermark in each node of the DOM tree corresponding to the target web page. Further, a first HTML source code represented by the watermark node may be determined. Furthermore, a field corresponding to a parameter value of the target attribute information in the first HTML source code may be monitored through a Mutation Observer (element viewer) to determine whether there is a modified target field.
In one embodiment of the present invention, the target attribute information of the target watermark may include: identification information, style information, and content information. The fields corresponding to the identification information comprise an id (identity identification) field and a class (type) field; the fields corresponding to the style information may include attributes fields; the fields corresponding to the content information may include a child list field and a child node field.
If the electronic device monitors that the modified target field exists, which indicates that the parameter value of the attribute information corresponding to the target field changes, the electronic device may determine that the attribute information corresponding to the target field is the attribute information to be processed. If there is no modified target field, the electronic device may determine that there is no pending attribute information for which the parameter value has changed.
In one embodiment of the present invention, referring to fig. 4, step S104 may include the steps of:
s1041: and acquiring initial parameter values of the attribute information to be processed.
S1042: and modifying the current parameter value of the attribute information to be processed recorded in the first HTML source code into the initial parameter value of the attribute information to be processed.
S1043: and rendering in the target webpage according to the modified first HTML source code to obtain the target watermark in the initial state.
In one implementation, when it is determined that the target watermark is modified, the electronic device may obtain an initial parameter value of the attribute information to be processed. And the initial parameter value of the attribute information to be processed corresponds to the target watermark in the initial state. Then, the electronic device may modify the current parameter value of the attribute information to be processed recorded in the first HTML source code to the initial parameter value of the attribute information to be processed.
Furthermore, the electronic device can render in the target webpage according to the modified first HTML source code to obtain the target watermark in the initial state. Additionally, the electronic device may not process if it is determined that the target watermark is unmodified.
In one embodiment of the present invention, referring to fig. 5, step S104 may include the steps of:
s1044: and generating a second HTML source code corresponding to the target watermark.
And the second HTML source code records initial parameter values of target attribute information of the target watermark.
S1045: and rendering in the target webpage according to the second HTML source code to obtain the target watermark in the initial state.
In one implementation, the target watermark is indicated as being modified when it is determined that there is pending attribute information for which the parameter value has changed. Accordingly, the electronic device may regenerate the HTML source code (i.e., the second HTML source code) corresponding to the target watermark based on the initial parameter value of the target attribute information of the target watermark. Furthermore, the electronic device may render in the target webpage according to the second HTML source code to obtain the target watermark in the initial state.
In an implementation manner, the electronic device may generate a second HTML source code corresponding to the target watermark through a callback function preset in the Mutation Observer, and render the target webpage according to the second HTML source code to obtain the target watermark in the initial state.
In addition, if the target watermark is deleted, the watermark node in the DOM tree corresponding to the target webpage is also deleted. After generating the second HTML source code, the electronic device may add the generated second HTML source code as a watermark node to a DOM tree corresponding to the target web page through a node insert function or a node add function.
Referring to fig. 6, fig. 6 is a schematic diagram of a watermarking method according to an embodiment of the present invention.
First, a malicious user may click a preset button (e.g., an F12 button) while browsing a target web page containing a target watermark. Accordingly, the electronic device may display a developer tools page. Therefore, in order to prevent a malicious user from opening the developer tool page through a target control (e.g., an F12 button, a "developer tool" button of a menu bar) during browsing a target web page containing a target watermark, the corresponding relationship between a target event (i.e., a user-triggered target control) and a display developer tool page can be unbound, and the target event and display preset information can be bound. Accordingly, when the electronic device monitors the target event, the electronic device may display preset information other than the developer tool page instead of the developer tool page.
Secondly, after opening the developer tool page, the malicious user may input a commonly used watermark identifier (e.g., watermark, logo, etc.) as a key into a search input box of an Elements page of the developer tool page. Correspondingly, the electronic equipment carries out retrieval according to the key words input by the user and displays the retrieved source codes containing the key words, and the retrieved source codes are watermark nodes in a DOM tree corresponding to the target webpage (namely HLML source codes corresponding to the target). Therefore, in order to prevent a malicious user from retrieving the source code of the target watermark through a commonly used watermark identification (e.g., watermark, logo, etc.), a random character string may be used as the watermark identification of the target watermark in a developer tool page.
In addition, after retrieving the HLML source code corresponding to the target watermark, a malicious user may modify or delete the retrieved HLML source code to modify or delete the target watermark in the target web page. Therefore, in order to prevent a malicious user from modifying or deleting the target watermark, the modification of the target watermark may be restored when the modification of the target watermark is monitored, that is, the target watermark may be modified to the initial state.
The watermark processing method provided by the embodiment of the invention has corresponding coping strategies for each step in the operation flow of modifying the watermark by a malicious user, can avoid the problem that the watermark in the webpage is deleted or modified, and further can improve the safety of the webpage.
Corresponding to the embodiment of the method in fig. 1, referring to fig. 7, fig. 7 is a block diagram of a watermark processing apparatus provided in an embodiment of the present invention, where the apparatus includes:
an obtaining module 701, configured to obtain preset attribute information of a target watermark in a target webpage when the target webpage is detected to be added with the target watermark; the preset attribute information is used for representing information calling of the target watermark in the target webpage;
