Problems solved by technology

There are potential safety hazards in the existing file access process. If the accessed file contains a virus or virus-infected content, the direct output of the file content is likely to cause the virus to run in the mobile terminal due to misoperation or unintentional operation, thereby affecting the mobile terminal. The security of the terminal has a serious impact, and may even affect the normal operation of the mobile terminal

Abstract

The embodiment of the invention provides a file access method and device, and a mobile terminal. The method comprises the following steps: when a file access request is received, judging whether a target file which requests to be accessed is a risk file or not; if the target file is the risk file, creating a temporary copy file for the target file; carrying out risk cleaning on the temporary copy file; and outputting the contents of the temporary copy file subjected to the risk cleaning to respond to the file access request. The safety of file access can be guaranteed, and the risk prevention and control capability of the mobile terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to the technical field of file access security of mobile terminals, and in particular to a file access method, device and mobile terminal. Background technique [0002] With the improvement of mobile terminal functions, the role played by mobile terminals in people's daily life is becoming more and more important. At the same time, more and more attention has been paid to the security of mobile terminals. At present, the access process for files in the mobile terminal is basically carried out directly. For example, if the user requests to access file A, the mobile terminal will output the content contained in file A to respond to the user's request; another example: the user opens the email, clicks the email The included attachments are accessed, and the mobile terminal outputs the attachment content in response to the user's access operation. There are potential s...
