Abstract

The invention discloses a data protection method and device of a mobile terminal, relates to information security and aims at solving the problems in the prior art that data in external storing equipment of the mobile terminal are easily disclosed or stolen. The technical scheme of the invention is that the data protection method of the mobile terminal comprises the following steps of: acquiring data confidentiality indication information if the data in the external storing equipment of the mobile terminal are required to be protected; transferring the data required to be protected in the external storing equipment to a built-in storing area of the mobile terminal according to the data confidentiality indication information; and protecting the data required to be protected and transferredto the built-in storing area. The data protection method and device of the mobile terminal, which are provided by the embodiment of the invention, are suitable for intelligent mobile phones, MIDs (Mobile Internet Devices), GSP (Global Position System) hand-held terminals and other mobile terminals.

Description

technical field [0001] The present invention relates to information security, in particular to a data protection method and device for a mobile terminal. Background technique [0002] For mobile terminals such as smart phones, mobile Internet devices (Mobile Internet Devices, MIDs), and GPS handheld terminals, external storage devices are generally used to expand their own storage areas. The user can store the data not only in the built-in storage area of ​​the mobile terminal, but also in an external storage device. [0003] While enjoying the storage convenience brought by external storage devices, users also face the threat of data security in external storage devices. Because the external storage device is easy to be pulled out from the mobile terminal by others without the permission of the user, the data stored in the external storage device faces the danger of being leaked or stolen. Contents of the invention [0004] Embodiments of the present invention provide a...
