The installation and use of the application involves relevant application files. The application files include privacy files such as application account numbers, passwords, communication records, and usage information, as well as non-private files such as temporary files and registration forms. The above application files are stored in In the user space, once the user space is invaded by a malicious process, it may lead to the leakage of private files, thus making the user's privacy or important files lose security, and the security of file storage is poor

The invention discloses a file protection method and device and a terminal. The file protection method comprises the steps that according to preset distinguishing conditions, application files are divided into privacy files and non-privacy files, the privacy files are stored into a first storage space, the non-privacy files are stored into a second storage space, the privacy files in the first storage space are hidden, virtual privacy files are generated correspondingly, and when an instruction of calling the privacy files in the application process is received, the virtual hidden files are controlled to be called. The corresponding virtual privacy files are virtualized in the first storage space so as to call other application processes, so that the privacy files are prevented from being leaked, the privacy files of a user are protected, and the file storage safety is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a file protection method, device and terminal. Background technique [0002] As the application of mobile terminals becomes more and more popular, while bringing convenience to users, it will also bring troubles to users. For example, leakage of private files such as address book, application account number, and password in application files is still a major security issue that users worry about. The installation and use of the application involves relevant application files. The application files include privacy files such as application account numbers, passwords, communication records, and usage information, as well as non-private files such as temporary files and registration forms. The above application files are stored in In the user space, once the user space is invaded by a malicious process, it may lead to the leakage of private files, thus making the use...
