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 storage method, a file display method, a file storage device, a file display method and a terminal. The method comprises the steps of obtaining a file name and a file type of a to-be-stored file; modifying the file name and the file type according to a preset rule to obtain the modified file name and file type; receiving encryption information input by the user; and encrypting and storing the to-be-stored file according to the modified file name and file type and the encryption information. According to the scheme, when the file is stored, the file name and the file type of the to-be-stored file are modified to hide the file. Furthermore, the to-be-stored file is encrypted and stored through the encryption information, so that another person can be prevented from illegally cracking the file after obtaining the file. Information leakage of a user can be effectively prevented through file hiding, encryption and storage, so that the information security of the terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a file storage and display 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 know...
