Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real Applying mode, the present invention is described in further detail.
Embodiment one
Referring to Fig. 1, Fig. 1 is the flow chart of the method for storage file between a kind of multiple domain provided in an embodiment of the present invention.This The method of storage file between the multiple domain that inventive embodiments provide, is applied to mobile terminal.As shown in Figure 1, this method comprises:
Step S101 when receiving the instruction of the unloading file of user's input, sends input authentication key to user Prompting message;
Specifically, the file is located at active user space, that is to say, that the file is certain in active user space File.
Optionally, when receiving the instruction of the unloading file of user's input, by the display screen of the mobile terminal and/ Or loudspeaker sends the prompting message of input authentication key to user.
Step S102 obtains the first authentication key of user's input;
Optionally, first authentication key is the fingerprint of user, alternatively, character set by user or character combination.
Step S103 judges whether first authentication key is pre-stored authentication key;
Specifically, if it is, authentication success, illustrates that user has the permission of file described in unloading, at this point, executing Step S104;
Step S104 controls the active user space for the file and is put into output end;
Specifically, the output end is corresponding with the mode of file described in unloading, it is the output end or shared of pipeline Region of memory.That is, the output end is the output of pipeline if realizing file described in unloading by way of pipeline End;If realizing file described in unloading by way of shared drive, the output end is shared region of memory.
Step S105 controls the first user's space corresponding with first authentication key from the output end and obtains institute File is stated, the unloading to the file is completed.
The technical solution that the embodiment of the present invention one provides is applied to mobile terminal, works as in the unloading for receiving user's input When the instruction of preceding user's space file, user's input authentication key is reminded, then obtains the first authentication key of user's input, Judge whether first authentication key is pre-stored authentication key, if it is, authentication success, that is to say, that logical The judgement is crossed to determine the permission of user, authentication successfully illustrates that user has the permission of file described in unloading, and identity is recognized The active user space is just controlled after demonstrate,proving successfully, the file is put into output end, control opposite with first authentication key The first user's space answered obtains the file from the output end, completes the unloading to the file, safety is relatively high, together When, the file is directly transferred to the first user's space corresponding with first authentication key, more convenient, specific table Now to apply technical solution provided by the invention, when user's file described in unloading, it is only necessary to want to turn to mobile terminal input The unloading to the file can be completed in authentication key corresponding to the user's space being stored to.Through from the above analysis it was determined that Using technical solution provided by the invention, can safely and conveniently cross-domain unloading file, to meet user cross-domain storage The demand of file can promote user experience well.
The method of storage file between the multiple domain that another embodiment of the present invention provides, optionally, further includes:
