Description

technical field [0001] The invention relates to computer system security, in particular to a method and system for protecting system files. Background technique [0002] With the popularization of modern smart terminals and the increase of user's personalized demands, users often wish to perform some personalized operations. At present, there are many third-party root tools on the market, and these third-party root tools can allow users to perform root authority operations on mobile terminals based on the Android system. The user of the Android system can realize the superuser authority operation (being root authority operation) to the Android system through these third-party root tools. At this time, the user has the supreme power of the entire system, and he can operate all objects. However, since ordinary users are not familiar with the Android system, when ordinary users with root privileges operate various operations on the Android system, since ordinary users do not k...
