[0155] As the Android system continues to become popular, more and more malicious software will tamper with system files, disguise themselves as system files to achieve malicious deduction, or hide their own process names to prevent anti-virus software from killing them, and even directly tamper with anti-virus software. The database file of the software is used to achieve the function of exempting from scanning and killing. This example provides a functional module for file anti-tampering protection, which is to protect files from malicious software attacks and perform anti-tampering protection on core files. By monitoring the behavior of the process and cooperating with the cloud virus scanning and killing mechanism, it automatically prohibits malicious software from obtaining root privileges, and guides users to delete malicious software through the output of alarm information, thereby protecting system security.

[0157] This example provides a method to prevent file tampering, including:
[0158] Such as Figure 6A As shown, the entry of "file system anti-tampering protection" is set on the first security page, and the setting page of root authority is entered from the "file system anti-tampering protection" of this page. After entering the setting page, you can choose whether to use the method provided by the embodiment of the present invention to set the root authority. or in Figure 6A On the page shown, if the option "file system anti-tampering protection" is checked, the method provided by the embodiment of the present invention will be used for file protection. exist Figure 6A Use a dotted frame to frame the "File System Anti-Tamper Protection" and its option controls.
[0159] Figure 6B As shown, the records formed during the root authority authorization process for running the method provided by the embodiment of the present invention. In this way, on the one hand, the ...

[0162] The Android system mainly uses the Ext2 file system to store files and supports extended file system attributes. However, there is no ready-made tool to realize this operation. This example provides a set of tools (Ktools) for setting file hidden attributes to realize file protection. The method of Ktools to modify file attributes can be as follows Figure 7 shown, including:
[0163] Step S1: Receive the hardening file configured in the cloud, for example, the terminal actively pulls the hardening file to be protected. The hardened file here is equivalent to the aforementioned file that requires enhanced protection. The movement is the network side where the server is located, including one or more servers.
[0164] Step S2: Request to obtain the root authority, and end directly if it cannot be obtained.
[0165] Step S3: start the ktools tool with root authority;
[0166] Step S4: Ktools tool analysis parameter, the parameter of analysis here comprises: file iden...
