Embodiment 1
[0049] see figure 1 , figure 1 A schematic structural diagram of a webpage anti-tampering system provided in the embodiment of this application, as shown in figure 1 As shown, the system includes: a terminal device 101 and a server 102;
[0050] The terminal device is configured with a client and an application having the function of a web browser;
[0051] The server is used to maintain an operation table corresponding to the page, and the operation table is used to record changes in the document object model structure supported by the page;
[0052] The client is used to execute the following webpage anti-tampering instructions:
[0053] Monitor whether the document object model structure of the web page changes;
[0054] If it is detected that the document object model structure changes, then according to the operation table corresponding to the web page, judge whether the detected change in the document object model structure matches the operation table; if they do not...
Embodiment 2
[0062] see figure 2 , figure 2 It is a schematic flow chart of a webpage anti-tampering method provided by an embodiment of the present application, the method is applied to a client, the client is associated with an application, and the application is configured with the function of a web browser, such as figure 1 As shown, the method includes: step 101-step 104;
[0063] In the embodiment of the present application, an application refers to an application configured with a web browser function, such as a web browser, an application configured with a web view (web view function) (such as: Tmall, Taobao, etc., an application with a page display function) application); if this type of application requires tamper-proof web pages, it needs to be bound and associated with the client, so that the client can provide web tamper-proof services for it.
[0064] In a specific implementation, when the application completes the initialization of the document object model structure of ...
example 1
[0083] Example 1: The node type of node 1 in the DOM structure is modified, and the change does not match the operation table. At this time, the client rejects the modification of the node type of node 1, thereby forcibly maintaining the original node 1 The type does not change.
