Step 21 further includes testing the configuration authority of the virtual machine by the authority modification module, so as to ensure that the virtual machine user only has the authority to configure the ip.
And step 22, the permission modification module of the copyright protection unit modifies the configuration file of the starting manager, sets a user name and a password for single-user mode login and the user name and the password for virtual machine operating system login, and realizes single-user mode login by setting the user name and the password for single-user login, so that a user is prevented from logging in the operating system by using the single-user mode, and acquiring a code or increasing the permission of a trial user. And the starting manager configuration file modified by the permission modification module is a grub configuration file.
And after the second step is finished, inputting a user name and a password when the user logs in the virtual machine, verifying and logging in the virtual machine, and starting the target protection software. The target protection software may set a start-up self-start.
And thirdly, copying the modification monitoring module of the copyright protection unit to different positions of an operating system by the system protection module of the copyright protection unit. The copy number of the system protection module to the modification monitoring module is more than or equal to two. Therefore, the difficulty of deleting the modification monitoring modules by a user through a third-party tool is increased, and the multiple modification monitoring modules simultaneously monitor whether the grub files are modified or not, so that the modification monitoring modules can find cracking behaviors in time.
The third step can be placed at any position of the first step and the second step, and only the modification monitoring module needs to be copied and stored at different positions of the operating system.
And step four, the copyright protection unit monitors whether the running time of the software service is overtime. The method specifically comprises the following steps: step 41, the modification monitoring module of the copyright protection unit monitors whether the startup manager file is modified, and when the startup manager file is modified, step 42 is executed; if not, step 43 is performed.
