Embodiment Construction

[0056] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0057] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the file protection method of the present invention. In this embodiment, the file protection method is applied to a mobile terminal, including the steps:

[0058] Step S10, when receiving the setting instruction, determine the corresponding file protection mode;

[0059]In this embodiment, for the determination of the file protection mode, preferably after the preset file protection mode is stored in the mobile terminal, the corresponding file protection mode is determined and set according to the setting instruction selected by the user. For example, a variety of different file protection modes, such as children's mode, accidental deletion prevention mode, etc., can be stored in the mobile terminal in advance. For exa...

Abstract

The invention discloses a file protection method, which comprises the following steps of: when a setting instruction is received, determining a corresponding file protection mode; and according to a relevant operation function forbidden by the file protection mode, determining to forbid to execute the relevant operation function of a protected file, wherein the relevant operation function at least comprises a deletion function and / or an editing function. The invention also discloses a file protection device and a mobile terminal. The relevant operation function of the file is forbidden so as to simultaneously prevent the file from being tampered or deleted under a situation that a user can normally check or play the file, and file safety is guaranteed so as to improve the use experience of the user.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a file protection method, device and mobile terminal. Background technique [0002] Currently, mobile terminals on the market generally protect important files by adopting encryption protection (such as digital password unlocking, graphic unlocking) and hidden methods. Although this method can prevent others from viewing the contents of the file, there is no guarantee that the file will not be deleted (for example, the encrypted file can be deleted even though the contents of the encrypted file cannot be seen), and there is no guarantee that the encrypted file will not be decrypted after decryption. be tampered with or deleted. However, files without any encryption protection are more likely to be tampered with or deleted, such as misoperations by children or users themselves in the process of using the mobile terminal. Therefore, this brings inconvenience...
