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. Such as 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...

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. Such as 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, pre...

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. Such as 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,...

Abstract

Disclosed are a multi-inter-domain file storage method and apparatus, and a mobile terminal. The method comprises: when an instruction input by a user for unloading a certain file is received, sending reminding information for inputting an authentication secret key to the user, wherein the file is located in a current user space; acquiring a first authentication key input by the user; judging whether the first authentication key is a pre-stored authentication key, and if so, identity authentication is successful, controlling the current user space to place the file to an output end; and controlling a first user space corresponding to the first authentication key to acquire the file from the output end, so as to complete the unloading of the file. The technical solution provided in the present invention can safely and conveniently unload a file in a cross-domain, so that the demand for user cross-inter-domain file storage can be met, and the user experience can be better improved.

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...
