Problems solved by technology

[0004] However, in the traditional technology, when a user is operating a smart terminal, if a disaster event such as a sudden power failure or a system crash occurs, the operating system has stopped running or cannot run normally when the disaster occurs, so the operating system cannot reset applications that have not been closed normally. The data storage of the program makes the important data of the user likely to be lost, thus making the data less secure

Embodiment Construction

[0036] In one embodiment, such as figure 1 As shown, a data protection method includes the following steps:

[0037] Step S102 , detecting the memory write operation of the application program.

[0038] A memory write operation is an operation input by a user through an application program. For example, when a user is editing a document, the user can obtain the user's typing operation through the keyboard, and write the memory according to the typing operation, and generate a character string in the memory according to the writing operation. The text entered by the user is recorded in the memory through the memory write operation.

[0039] Step S104, when it is detected that a memory write operation occurs, persistently store the memory mapping data of the application program to a preset storage area according to the memory write operation.

[0040] Persistent storage is about storing data on disk, flash memory, or in a database. The data in the memory cannot be saved afte...

Abstract

The invention relates to a data protection method. The data protection method includes detecting internal storage write operation of an application program and subjecting memory mapping data to persistence storage into a preset memory area according to the internal storage write operation when the internal storage write operation is detected. Besides, the invention further provides a data protection device. The data protection method and the device are capable of improving the safety of data.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a data protection method and device. Background technique [0002] In traditional technologies, smart terminals are driven by corresponding operating systems. For example, personal computers can be driven by operating systems such as windows and linux, and mobile terminals can be driven by operating systems such as ios and android. The operating system is the bridge between the upper application and the lower layer, and the application software works on the platform provided by the operating system. [0003] Before the user shuts down the smart terminal, if there is still a running application, the operating system prompts the user to save the data of the application before exiting the shutdown, thereby preventing data loss due to shutdown. [0004] However, in the traditional technology, when a user is operating a smart terminal, if a disaster event such as a sudden ...
