Problems solved by technology

[0003] For the safety of users, in the solution of multi-domain (that is, multi-user space), each user space is relatively independent and isolated to a certain extent. Although there is always a direct or indirect connection between each domain, the current technology However, it is still impossible to safely and conveniently transfer files between domains. In fact, users often have the need to store files across domains. Therefore, the current technology cannot meet the needs of users, and the user experience is poor.

Embodiment 1

[0063] see figure 1 , figure 1 It is a flowchart of a method for storing files between multiple domains provided by an embodiment of the present invention. The method for storing files between multiple domains provided by the embodiment of the present invention is applied to a mobile terminal. like figure 1 As shown, the method includes:

[0064] Step S101, when receiving an instruction to transfer a certain file input by the user, send a reminder message to the user to input the authentication key;

[0065] Specifically, the file is located in the current user space, that is, the file is a certain file in the current user space.

[0066] Optionally, when an instruction to transfer a certain file input by the user is received, a reminder message to input the authentication key is sent to the user through the display screen and / or speaker of the mobile terminal.

[0067] Step S102, acquiring the first authentication key input by the user;

[0068] Optionally, the first au...

Embodiment 2

[0079] see figure 2 , figure 2 It is a flow chart of another method for storing files between multiple domains provided by an embodiment of the present invention. The method for storing files between multiple domains provided by the embodiment of the present invention is applied to a mobile terminal. like figure 2 As shown, the method includes:

[0080] Step S201, when receiving an instruction to dump a file input by the user, send a reminder to the user to input the authentication key, and the file is located in the current user space;

[0081] Step S202, obtaining the first authentication key input by the user;

[0082] Step S203, acquiring and storing the authentication key input by the user and corresponding to the user space;

[0083] Specifically, different user spaces correspond to different authentication keys. One user space can correspond to one or more authentication keys, and one authentication key can correspond to one or more user spaces. However, prefer...

Embodiment 3

[0094] see image 3 , image 3 It is a flow chart of another method for storing files between multiple domains provided by an embodiment of the present invention. The method for storing files between multiple domains provided by the embodiment of the present invention is applied to a mobile terminal. like image 3 As shown, the method includes:

[0095] Step S301, when receiving an instruction to dump a file input by the user, send a reminder message to the user to input the authentication key, and the file is located in the current user space;

[0096] Step S302, acquiring the first authentication key input by the user;

[0097] Step S303, judging whether the first authentication key is a pre-stored authentication key;

[0098] Specifically, if yes, the identity authentication is successful, and step S304 is executed.

[0099] Step S304, if it is determined that the file is an encrypted file, control the current user space to decrypt the file;

[0100] Specifically, th...

Abstract

The invention discloses a multi-inter-domain file storage method, apparatus and mobile terminal. The method comprises steps of sending reminding information of an input authentication secret key by a user while receiving an instruction for unloading a certain file in current user space and input by the user, acquiring a first authentication secrete key input by the user, and determining whether the first authentication secret key is a pre-stored authentication secrete key, if the first authentication secret key is a pre-stored authentication secrete key, identity authentication is successful; the file in the current user space is controlled to be placed on an output end; first user space corresponding to the first authentication secret key is controlled to acquire the file from the output end; and file unloading can be achieved. By the use of the technical scheme, files can be safely and conveniently unloaded in a cross-domain, so demands for user inter-domain file storage can be met and user experience can be enhanced.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method, device and mobile terminal for storing files between multiple domains. Background technique [0002] With the deepening of user differentiation for mobile terminals and the increasingly prominent security issues of mobile terminals, multi-domain (that is, multi-user space) is a good solution. It provides a lightweight system virtualization solution that allows multiple Each user runs on an operating system, each user has its own user space, and the resources of each user space are isolated from each other. Compared with the multi-operating system system terminal solution, the terminal multi-domain solution consumes much less resources (such as CPU, memory, etc.) and does not have such high requirements for terminal performance. Therefore, it has a broader application prospect . [0003] For the safety of users, in the solution of multi-domain (that is, mul...
