System operation method and terminal

The invention discloses a system operation method and a terminal. The method can comprise the following steps that: receiving the operation request of a first system application; responding to the operation request, obtaining a current operation parameter corresponding to the first system application, and determining a first checkout value corresponding to the current operation parameter according to the current operation parameter and a preset calculation strategy, wherein the current operation parameter is an operation parameter that an initial operation parameter corresponding to the first system application is revised and updated in a first storage area corresponding to the initial operation parameter; and when the first checkout value is not matched with a preset checkout value, stopping operating the first system application, wherein the preset checkout value is a checkout value corresponding to the initial operation parameter. When the above method is adopted, the system application can not operate aft
