Embodiment Construction
[0033] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0034] Such as figure 1 As shown, it is a structural diagram of a dual-system terminal provided by an embodiment of the present invention, please refer to figure 1 The dual-system terminal 10 includes an area division module 101, an area mounting module 102, and an instruction receiving module 103; the area division module 101 is used to divide the data storage area in the dual-system terminal 10 into safe storage areas according to preset rules area and common storage area; the area mounting module 102 is used to mount the safe storage area and the common storage area under the security system, and mounts the common storage area under the common system; the instruction receiving module 103 is used to receive An operation instruction for the user to read and write data to the secure storage area and an ordinary storage area under...

The present invention provides a data reading and writing method for a dual-system terminal and a dual-system terminal. The dual-system terminal includes: an area division module for dividing the data storage area in the dual-system terminal into safe storage areas according to preset rules. area and common storage area, the area mounting module is used to mount the safe storage area and common storage area under the security system, and mounts the common storage area under the normal system; the instruction receiving module is used to receive An operation instruction for the user to read and write data to the secure storage area and an ordinary storage area under the security system; or, receiving an operation instruction for the user to read and write data to the ordinary storage area under the ordinary system. This solution solves the problem that the important content of the security system in the dual-system terminal can also be read and written on the common system, which easily leaks private data, and prevents the problem that the data in the dual-system terminal is easy to leak.
Description
technical field [0001] The invention relates to the technical field of electronic communication, in particular to a method for reading and writing data of a dual-system terminal and a dual-system terminal. Background technique [0002] With the rapid development of terminal technology, in order to pursue more diversified interface effects, users increasingly like to install two systems on one terminal. In this way, when users are tired of the interface or operation mode of one of the systems, System switching can be performed to satisfy different operating experiences or interface effects. However, in the prior art, the dual-system terminal does not really effectively use the function of the dual system to safely read and write data in terms of data storage. Usually, users store photos, audio and video files, emails and other content in the external memory card in the dual-system terminal, such as an SD card, or in the built-in extended memory of the terminal, no matter whe...
