Problems solved by technology

However, when the user carries the terminal with him, the terminal is lost or the storage device (such as a memory card) in the terminal is lost.
Once the terminal or the storage device in the terminal is lost, the information stored by the user is easy to be known by others, resulting in the leakage of user privacy information
[0004] Therefore, the current terminal cannot effectively protect the information stored by the user, resulting in low information security of the terminal

Abstract

The embodiment of the invention provides a file protection method and device, and a terminal. The method comprises the following steps of: when a file is detected to operate, receiving decryption information input by a user; comparing the decryption information with encryption information in the file to obtain a comparison result; according to the comparison result, judging whether the decryption information is abnormal or not; and if the decryption information is abnormal, transferring the file to a preset storage position. By use of the scheme, after the user inputs the decryption information, whether the decryption information is abnormal or not is judged through the comparison result of the decryption information and the encryption information in the file, and the file is transferred when the decryption information is abnormal. When other people carry out illegal cracking on an encrypted file, the file can be transferred, and a phenomenon that the private file of the user is illegally obtained by other people so as to cause the leakage of the private information of the user is avoided so as to improve the information security of the terminal.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a file protection method, device and terminal. Background technique [0002] With the development of terminal technology, users rely more and more on terminals such as smart phones, and the storage space of terminals is also increasing. Users can store various information in the terminal. For example, the user can store multimedia information such as music and video in the terminal, and can also store private information such as address book and short message. [0003] On the other hand, due to the portability of the terminal, users usually carry the terminal with them. However, when the user carries the terminal with him, the terminal is lost or the storage device (such as a memory card) in the terminal is lost from time to time. Once the terminal or the storage device in the terminal is lost, the information stored by the user is easy to be known by others, resu...
