Detailed ways

The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

In order to ensure the information security of the mobile terminal, the server on the network side is equipped with a user identity authentication unit, which is used to confirm the ownership of the user of information resources; a user information preprocessing unit, which is used to extract the type of user terminal and various information The storage format of the source; a registration unit is used to realize the binding relationship between the user's SIM card and the user's mobile phone, that is, to establish the customer identification number (International Subscriber Identification Number: IMSI) and the International Mobile Equipment Identity (International Mobile Equipment Identity: IMEI) ) binding relationship; a database for storing various data information, and also includes: an information recovery device. The network side can realize information backup function, information recovery function, information destruction function and alarm function.

Before performing the above operations, it is necessary to establish the binding relationship between the IMSI and IMEI of the mobile terminal in the registration unit on the network side, and the mapping relationship table between the service password and the operation object corresponding to various operations, for example: backup a certain file and the operation password Mapping, destroying all files and mapping of operation passwords, etc., performing different operations corresponds to different service passwords.

The network side implements the information backup function, which can back up the information resources of the mobile terminal to the database of the server on the network side, so as to transmit them to the mobile terminal when needed, so that the mobile terminal can re-establish the original information resources. Referring to Figure 1, the implementation steps are as follows:

Step 101: the network side receives the user's backup request, that is, the mobile terminal submits a backup information application to the network side by providing the target mobile terminal IMSI and service password;

The information backup request is: the user service password sent by SMS, telephone or voice service, multiple service passwords can be set in the registration unit, corresponding to different backup information requests respectively.

Step 102: If the network side confirms that the reported target mobile terminal IMSI matches the service password, it confirms that the user's backup information request is legal, that is, the user has ownership of the information resources of the target mobile terminal;

Step 103: Receive the information resource data to be exported selected by the mobile terminal. Different service passwords can select different information resource backups, which have been set in the registration unit;

Step 104: Encrypt the received data with the user password, and save it in the database on the network side. The data includes information such as the format name and backup version of the information source. These auxiliary information are automatically added when the received data is stored in the database.

The network side can realize the information recovery function, and when the user loses the mobile phone and loses the original information resources or when the information is damaged, the personal information resources can be re-established. Data recovery means covering various existing information resources in the mobile terminal, so it is necessary to identify the user's write authority and the ownership of the user's information files on the network side to prevent malicious recovery. Therefore, before the user performs the information recovery service, the information resources on the current mobile phone can be backed up first.

Information recovery function is realized by information recovery device, with reference to shown in Figure 2, information recovery device comprises the recovery request receiving unit 21 that is connected in turn, is used for receiving the information recovery request of mobile terminal; Recovery authority judging unit 22, is used for determining whether this device Have data writing authority and the content of request recovery; Information calling unit 23, is used for calling the backup information data in the network side server; Data processing unit 24, is used for backup data decryption and format conversion; Data sending unit 25, is used for The processed data is sent to the target terminal.

Shown in Fig. 3 with reference to, information is restored on the mobile terminal and comprises the following steps:

Step 201: the network side receives the information recovery request of the mobile terminal;

The information recovery request is: the user service password sent by SMS, telephone or voice service, multiple service passwords can be set in the registration unit, corresponding to different recovery information requests.

Step 202: If the network side confirms that the reported target mobile terminal IMSI matches the service password, then confirm that the mobile terminal has write permission;

Step 203: use the IMSI to find the corresponding backup file in the database;

Step 204: use the service password to decrypt the backup file;

Step 205: select resource data according to the need to resume information instruction sent by the user;

Step 206: Read the type information of the mobile terminal, extract the terminal information resource format, and convert the information source format in the database;

Step 207: Send the converted data to the mobile terminal, and the mobile terminal performs a corresponding write operation.

The purpose of information destruction on the network side is: when the user's mobile phone is lost, the program in the target terminal is triggered by sending instructions to the target terminal to complete the destruction of information resources.

Referring to Figure 4, the implementation method of information destruction on the network side includes the following steps:

Step 301: the network side receives a request from a user to destroy information resources;

The request to destroy information is to send the IMSI and service password of the target mobile terminal through SMS, telephone or voice service. Multiple service passwords can be set in the registration unit, corresponding to requests for destroying different information.

Step 302: If the network side confirms that the reported target mobile terminal IMSI matches the service password, it confirms that the user has information ownership of the target mobile terminal, and then destroys the information;

Step 303: The network side searches for the IMEI of the mobile terminal according to the established binding relationship between the IMSI and the IMEI, starts the process and waits for the target mobile terminal to register on the network;

Step 304: When the network side discovers that the target mobile terminal is registered in the network, locate the new IMSI of the target mobile terminal in the HLR;

Step 305: Send an instruction related to information destruction to the mobile terminal, so that it starts a stored program to automatically destroy information.

The function of realizing the alarm function on the network side is: after the mobile phone is lost and is used again, when the binding information of the user’s IMSI and IMEI is found to be inconsistent with the saved one on the network side, an alarm will be triggered to prohibit the use of the SIM card, and at the same time, the new card will be replaced. Notify the owner of the information.

Referring to Figure 5, the alarm implementation process on the network side is as follows:

Step 401: when the mobile terminal registers online, the network side obtains the IMSI and IMEI information of the mobile terminal;

Step 402: The network side compares and judges the obtained IMSI and IMEI information with the pre-stored IMSI and IMEI binding information, and if the two are found to be inconsistent, execute the next step, otherwise, do not process;

Step 403: the network side prohibits the use of the SIM card of the IMSI;

Step 404: the network side sends the information of the new SIM card to the location specified by the user.

In this step, the new card information can be sent to a designated terminal by means of a short message message or a phone call, or can be sent to a designated wap mail server by email.
