Inventor: LI QIGANG
IPC: G06F21/32
Filed: 2019-01-04
Abstract: A system security method and apparatus, a computer device, and a storage medium. The method comprises the following steps: obtaining a screenshot of a display image in a display region (S1100); inputting the screenshot into a preset first neural network model and obtaining a first classification result of the screenshot output by the first neural network model (S1200); and comparing the first classification result with preset behavior planning information, and when the first classification result is consistent with the behavior planning information, responding to a user instruction of the user (S1300). The classification result is user behavior information represented by the screenshot, i.e., a user is using the computer device to perform which operation. Therefore, whether the user uses a computer to perform a planning behavior operation instead of performing other operations can be determined by comparing whether the behavior planning information set when the user uses the computer is consistent with the classification result, thereby achieving a task of helping the user stop the improper use of the computer.
