Detailed ways

The basic idea of the present invention is: multiple user interfaces are set in the mobile phone, and for different users, tell the corresponding access password of the user interface expected to be accessed by the user, or the access password and account, and implement the user interface through the user interface. The restriction on the user's use of the functions of the mobile phone realizes the protection of the information of the mobile phone user and makes it possible for the mobile phone user to share a mobile phone with others. The invention is simple to realize, convenient and practical.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

Fig. 1 is the flowchart of the mobile phone management method based on multi-user of the present invention, as shown in Figure 1, the mobile phone management method based on multi-user of the present invention comprises the following steps:

Step 101: setting more than two user interfaces for the mobile phone, at least one of the user interfaces has the ability to set the usage authority of each application function of the mobile phone for the remaining user interfaces, and set access passwords for each user interface respectively, or Access passwords and accounts.

When loading an operating system and an application program on a mobile phone, user interfaces accessed by multiple users are provided for different users to access, and corresponding application functions are provided for different users. Among these user interfaces, at least one is for administrator users to access. Users who access through this user interface can use all the application functions of the mobile phone, and can set the permissions of other user interfaces for the use of mobile phone application functions, such as Some application functions are blocked, or other user interface access users can see some application functions, but are prohibited from using them.

The application functions include calling out, answering calls, sending short messages, checking newly received short messages, changing mobile phone setting information, checking and changing information in the mobile phone storage area, and subscriber identity module (SIM, Subscriber Identity Module) card Checking and changing stored information, web browsing, etc., are the basic functions that mobile phones can provide.

Among the present invention, mainly carry out the management of machine card application function to mobile phone, promptly the use of the FLASH storage area application function of SIM card and mobile phone is managed, wherein, the management related to SIM card comprises:

1) Normal use. The mobile phone can normally make and receive calls, send and receive short messages or multimedia messages, browse the web, modify the PIN code (personal identification code of the SIM card), edit and save short messages or multimedia messages, modify contact information and other data.

2) Not consumable. Mobile phones cannot make and receive calls, send short messages or multimedia messages, and browse webpages; however, they can receive short messages or multimedia messages, modify PIN codes, edit and save short messages or multimedia messages, and modify contact information and other data .

3) SIM card attributes cannot be modified. The mobile phone can normally make and receive calls, send and receive short messages or multimedia messages, browse the web, edit and save short messages or multimedia messages, modify contact information and other data; but cannot modify the PIN code operation.

4) The SIM card is not registered. The mobile phone is not registered to the legal network, and can only dial emergency numbers, and cannot access modules such as short messages, multimedia messages, calls, browsers, and contacts.

There are five ways to manage the use of mobile phone FLASH (flash memory):

1) Normal use. You can edit and save call records, short messages, multimedia messages, browser records, contacts and other data.

2) Cannot store any data. You can edit data such as call records, short messages, multimedia messages, browser records, contacts, etc., but they cannot be saved to the phone's FLASH. After booting, the data will be lost, and it is still the data before modification.

3) No information can be read out. After booting, data such as call records, short messages, multimedia messages, browser records, and contacts are empty. Can not read out the information of the mobile phone FLASH, to prevent others from seeing the information on the mobile phone.

4) The current setting cannot be stored. The current settings of the phone can be edited, but not saved. After booting, the settings before modification are still displayed. After preventing settings from being modified, it is difficult to recover.

5) Only the factory settings are displayed. Hide the last settings and only show the factory settings. Just like the mobile phone you just bought. It is not possible to edit and save the factory settings.

The following uses a specific example to describe in detail how to complete the setting of user interface application function permission in step 101 .

2 is a schematic diagram of the present invention setting user interface application function usage rights through the administrator user interface. As shown in FIG. Enter the setting interface X01 of the mobile phone through the administrator user interface, including two options of "user and password setting" and "user card management", wherein the "machine card" is the mobile phone and the SIM card of the mobile phone; Select "User and Password Settings" to enter the user and password setting interface X011, which is divided into administrator password and restricted user password, as shown in X01111 to X01113 in Figure 2. If you need to modify the administrator password, you must first enter The correct old administrator password, the old password is verified, and then the new password can be entered. The limited users are ordinary users, which are users who are not owners of mobile phones. And if you need to modify the restricted user password, you only need to directly enter the new password twice without verifying the old password, as shown in X01121 to X01122 in Figure 2 . As shown by X012 in Figure 2, if you select "User Card Management", you will enter the user card management interface, and you can set the management attributes of multiple restricted user cards. If 1 is selected, the interface of the current machine card management attribute of the restricted user 1 is displayed, as shown in X01211 in FIG. 2 , to display and modify the machine card management attribute of the restricted user 1. When I first entered, the SIM card and mobile phone FLASH were all normal use attributes. Select the SIM card, enter the SIM card management interface (single-choice list), you can choose "non-consumable", as shown in X01212 to X01213 in Figure 2; when selecting a mobile phone, enter the mobile phone management interface (single-choice list), you can select "No data can be stored", as shown by X01214 to X01215 in Figure 2. Then, the user interface corresponding to the restricted user 1 cannot make or receive calls, send short messages or multimedia messages, or browse web pages; People and other data are saved to the mobile phone. The machine card management attribute of restricted user 1 can be modified repeatedly.

If you choose 2, you can display the interface of the current machine card management attribute of the limited user 2, as shown in X01221 in Figure 2, display and modify the machine card management attribute of the limited user 2. When I first entered, the SIM card and mobile phone FLASH were all normal use attributes. Select the SIM card and enter the SIM card management interface (single-choice list), you can select "SIM card not registered", as shown in X01222 to X01223 in Figure 2; select the mobile phone, enter the mobile phone management interface (single-choice list), you can Select "Cannot store current settings", as shown in X01224 to X01225 in Figure 2. Then, the user interface corresponding to the limited user 2 after setting can only dial emergency numbers, and cannot access modules such as short messages, multimedia messages, calls, browsers, and contacts; the current settings of the mobile phone can be edited, but cannot be saved . The present invention can modify the machine card management attribute of the limited user 2 repeatedly.

Those skilled in the art should understand that it is easy to set multiple user interfaces through the operating system on the mobile phone and implement the setting of limited user interfaces through the administrator user interface.

Step 102: After receiving the user's access password, or the input of the access password and account, determine the user interface that the user wants to access according to the input access password, or the access password and account, and pass the user interface that the user wants to access. The interface provides the user with the application functions that the user interface has permission to use.

After the mobile phone is set through the setting method in step 101, the mobile phone supports three different user interfaces. If you need to lend the mobile phone to others at this time, you can inform the other party of the limited user 1 or limited user 2 The access password of the interface (restricted user password), after the user passes the verification of the access password of the user interface of the limited user 1 or limited user 2, the mobile phone provides corresponding application functions respectively. For example, the usage mode of the SIM card of the limited user 1 accessed through the user interface cannot be consumed, and the usage mode of the FLASH of the mobile phone cannot store any data. Restricted user 1 cannot use a mobile phone to make and receive calls, send short messages or multimedia messages, or browse web pages. The SIM card usage method of the limited user 2 is that the SIM card is not registered, and the usage method of the mobile phone FLASH is that it cannot be stored. Like this, the limited user 2 that accesses through the user interface can only use the mobile phone to dial out emergency numbers such as 110, etc., and cannot access information such as short messages, multimedia messages, call records, browsers and contacts, and can edit the current phone number. settings, but cannot be saved.

If the access mode of account and access password is set for different user interfaces, and the access password verification is performed after entering the account, the security of information management can be further enhanced. When only access passwords are set for the user interface, the access passwords set for different user interfaces are different, and the mobile phone determines which user interface the user wants to access through the input access password.

In order to further enhance the security of the mobile phone, when the mobile phone of the present invention receives the access password of the access user interface input by the user and exceeds the set times, it will lock the SIM card or display screen of the mobile phone, and the locked SIM card will not be accessed. To use, a special unlock password must be used to unlock, or the SIM card must be unlocked through the operator. If an account is also set for the user interface, when any input error in the account and access password exceeds the set number of times, the SIM card of the mobile phone will be locked; or, when the input of the account and the access password exceeds the set number of times, Lock the SIM card of the mobile phone. After the display screen is locked, the user will not be able to perform any operations on the mobile phone, and can only re-select the user interface that needs to be accessed (access password, or authentication of the access password and account) after the screen is unlocked.

The present invention also includes the step of: locking the current user interface when it is detected that the mobile phone has not been used beyond the set period of time. A special timer can be set in the mobile phone. If the timer expires without detecting any key operation, and no application function is currently enabled, the mobile phone will enter the locked state, and the currently used user interface will be locked. , it can only be used by re-entering the access password of the corresponding user interface.
