A data processing method and device

Abstract

The embodiment of the invention discloses a method and a device for processing data, which are applied to a first application program. The method comprises the following steps of intercepting and capturing a data operating order related to hardware data and sent by a second application program, wherein the data operating order carries identification information of the second application program and an operation type of operation carried out on the hardware data; judging whether the operation type is a preset protection type or not; determining a target process path corresponding to the second application program according to the identification information of the second application program when the operation type is the preset protection type; judging whether the target process path belongs to a preset process path set or not; discarding the data operating order if the target process path belongs to the preset progress path set. By applying the method disclosed by the embodiment of the invention, the situation that data of a terminal are damaged and the user experience is influenced because the hardware data are tampered can be prevented from happening.

Description

technical field [0001] The invention relates to the field of computer system optimization, in particular to a data processing method and device. Background technique [0002] For a terminal, it has various types of hardware data, such as MSR partition, data bus, port, physical memory, and so on. Among them, since the hardware data affects the normal operation of the terminal, the security of the hardware data is very important. For example, the data bus belonging to the hardware data can transmit the data of the CPU to other components such as memory or input and output interfaces, and can also transfer other The data of the component is transmitted to the CPU. If the data on the data bus is modified, the processing result of the CPU will be modified, which will seriously damage the data of the terminal. [0003] However, in recent years, various application programs have emerged one after another, and there are great hidden dangers in various data in the terminal, especial...

Among them, since the hardware data affects the normal operation of the terminal, the security of the hardware data is very important. For example, the data bus belonging to the hardware data can transmit the data of the CPU to other components such as memory or input and output interfaces, and can also transfer other The data of the component is transmitted to the CPU. If the data on the data bus is modified, the processing result of the CPU will be modified, which will seriously damage the data of the terminal.

[0003] However, in recent years, various applications have emerged one after another, and there are great hidden dangers in various data in the terminal, especially hardware data.

Specifically, for hardware data, some applications can read and write hardware data by calling the NtSystemDebugControl function of the kernel, such as malicious software, to modify the hardware data, which in turn leads to the destruction of terminal data, causing troubles for users
