Their respective data peers are unobservable, thus achieving the effect of confidentiality of data information, and is applicable to various user groups. In this embodiment, a series of operation modes such as user creation, switching, and deletion are also provided to facilitate use between different users. What's important is that unlike other ways of judging different users through parameter attributes, each user is opened up storage space, and other users have no access in any way, and other methods in the related art, such as distinguishing users by parameter attributes. As long as you access the file system of the mobile phone through the adb command, you can still access the data of other users. Rather than being a true multi-user system, data is essentially shared, and in the above embodiments, data security is fundamentally protected by giving each user different file system permissions.

In order to solve the privacy of the mobile phone data for each user group and to protect the data, in the embodiment, a multi-user system is also provided, which allocates respective storage spaces to each user on the file storage, and gives these The storage space is allocated different access rights. Users cannot access the data of other users. Each user will have its own set of file system structure, thus fundamentally eliminating data leakage. It is a true multi-user system. This system can really solve the privacy problem of user data.

The system can be based on the development environment of the Android system, and when the mobile phone is powered on, the memory of the mobile phone is classified and mounted. If the user is in a multi-user state, each user is allocated a corresponding storage space from the memory. Create their own mount points, define the corresponding environment variables, and do the processing of unshared attributes between processes.

Based on the Android system development environment, the user is provided with a corresponding menu for creating a user, and is provided to the corresponding UI, so that the user can set the corresponding parameters of the newly created user and the manner of unlocking the lock screen, and save all the new users. Information and create a data storage space for new users.

Based on the Android system development environment, users are provided with convenient user switching interactions, and different unlocking patterns are used to match different users, so that users can be quickly switched at any time.

Based on the Android system development environment, the user is provided to delete the interaction of a user, but the function of deleting the user is limited to the system user deleting the ordinary user, and the ordinary user cannot delete the user, and the ordinary user has no permission to delete the system permission. User.

Based on the Android system development environment, the installation package will be managed, each user will have its own data storage directory, and for each user, the system will maintain its installed software state in some form, the state will be somehow Save it and have a corresponding backup.

The embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 9 is a flowchart of allocating storage space of each user in a multi-user state during a mobile phone startup process according to an embodiment of the present invention. As shown in FIG. 9, the process includes the following steps: Step S902: determining whether it is a multi-user State, if the determination is yes, proceed to step S904, otherwise proceed to step S908;

First, a mount point path is created. The mount point path includes the path where the sdcard is actually to be mounted and the directory where each user mounts the sdcard. And then define the corresponding environment variables, which can be configured in the system startup configuration file;

Step S906, performing an inter-process non-shared attribute setting (unshared ( )) on the mount point, the attribute is owned by Linux, and Android also has the attribute setting. Setting this property can make the mount points created by each user not shared, only visible to themselves, so that users can not access the file system of other users. Each user has its own set of independent file system, through the file manager and other mobile phones. The application can only see the files in the user's own storage path. The files of other users cannot be seen. For example, only the photos taken by user A can be seen in user A, and only the user status of user B is entered. You can see the photos taken by User B. When you install the mobile app, the applications installed by each user cannot be shared. For example, User A installs a third-party mobile phone application. After entering User B, it is not possible in the mobile phone. If you see the application, if user B wants to use the application, the application can be used normally only after the user's user status is installed. The storage path is used to hide the user's file system. ;

Step S908: Load the application corresponding to the user, and enter the corresponding lock screen interface, that is, after the storage path is created, the application corresponding to the user is loaded, and the lock screen interface unique to the user is entered.

FIG. 10 is a flowchart of creating a user according to an embodiment of the present invention, as shown in FIG. The process includes:

Step S1002, detecting whether the caller has the required authority, that is, before creating a new user, it is necessary to check whether there is a required permission, and only the user with the system authority can create a new user to proceed to step S1004, and if there is no permission, return;

Step S1004, checking whether the multi-user environment reaches the limit of the number of users, that is, if there is permission to create a new user, and then checking whether the current number of users has reached the maximum number, if it has been reached, then return, otherwise proceeds to step S1006;

Step S1006: Create a related directory for the new user, that is, if the current number of users has not reached the maximum, add a new user, and create a user directory for the new user;

Step S1008, serializing the user list, that is, modifying the user list, the list is used to maintain all user information, such as a user name, a user ID, and the like;

Step S1010: Establish a corresponding data directory, parameter setting, etc. for the user, that is, create a data storage directory for the user, and perform basic parameter setting of the newly created user, including an unlocking manner, and the unlocking mode is saved in the corresponding data structure;

Step S1012, setting an unlock pattern;

In step S1014, it is determined whether the unlock pattern is repeated, that is, after the unlock pattern is set, a traversal comparison is performed. If the unlock pattern of the newly created user conflicts with the unlock pattern of the previous user, the user is prompted to reset, until no more conflicts, otherwise End the process;

Step S1016, ending the process.

FIG. 11 is a flowchart of switching between users according to an embodiment of the present invention. As shown in FIG. 11, the process includes:

Step S1102: Acquire a corresponding user according to the unlock pattern input by the user, that is, if you want to switch the user, directly press the POWER button to lock the screen, and then input the unlock pattern of the user who wants to switch, and the mobile phone searches according to the unlock pattern. The corresponding user, if the input unlock pattern does not match any user, prompt the user to re-enter; Step S1104: Obtain the switching target user information, and set the current user as the target user, that is, obtain the data information of the target user;

Step S1106, setting the current user as the target user, and locking the screen;

Step S1108: The state of the switching target user is a "starting" state;

Step S1110: Switch the activity stack of the target user to the current user.

Step S1112, storing directory switching, security setting switching, etc., opening the lock screen interface of the target user, that is, performing operation such as storage directory switching, security setting switching, and displaying the lock screen interface of the target user, and thus, the user information has been updated, the target The user has also switched to the foreground.

FIG. 12 is a flowchart of removing a user according to an embodiment of the present invention. As shown in FIG. 12, the process includes:

In step S1202, it is detected whether the caller has the required permission, that is, before removing a user, it is necessary to check whether there is a required permission, and only the user with the system authority can remove the user, and proceeds to step S1204, and if there is no permission, returns;

In step S1204, if there is permission, the user id is added to the user list to be removed, and the user status is set to "to be removed", and the user is cleared when the system is started next time;

Step S1206, stopping the user, killing the user process;
