实现移动终端数据保护的方法Method for Realizing Mobile Terminal Data Protection

技术领域technical field

本发明涉及一种实现移动终端数据保护的方法，特别是一种在移动终端丢失或被盗的情况下，实现对移动终端中记录的数据信息进行保护的方法。The invention relates to a method for realizing data protection of a mobile terminal, in particular to a method for protecting data information recorded in a mobile terminal when the mobile terminal is lost or stolen.

背景技术Background technique

随着移动通信技术水平的提高，移动终端设备的功能日益复杂化，记录的内容不断丰富，同时移动终端设备的样式日趋小巧便携。但同时，移动终端设备灵活、小巧的优点带来了容易丢失或被盗窃的风险，而记录内容的丰富也造成了丢失或被盗后用户信息的大量泄漏。With the improvement of mobile communication technology, the functions of mobile terminal equipment are becoming more and more complex, and the recorded content is constantly enriched. At the same time, the style of mobile terminal equipment is becoming smaller and more portable. But at the same time, the advantages of flexibility and compactness of mobile terminal equipment bring the risk of easy loss or theft, and the richness of recorded content also causes a large amount of leakage of user information after loss or theft.

为了克服这一问题，在移动终端丢失或被盗的情况下，实现对移动终端内容数据的保护，目前主要采用以下三种方法：In order to overcome this problem and realize the protection of the content data of the mobile terminal when the mobile terminal is lost or stolen, the following three methods are mainly used at present:

1、终端开机密码保护方法，即移动终端在每次开启时都需要用户输入密码，不输入密码或者所输入密码不正确，移动终端都不能正常开启，从而实现对移动终端内容数据的保护；1. The terminal power-on password protection method, that is, the mobile terminal requires the user to enter a password every time it is turned on. If the password is not entered or the entered password is incorrect, the mobile terminal cannot be opened normally, thereby realizing the protection of the content data of the mobile terminal;

2、终端SIM卡密码保护方法，即移动终端检测到所插入的SIM卡发生变更时，需要用户输入密码，不输入密码或者所输入密码不正确，移动终端阻止SIM卡启动，从而实现对移动终端内容数据的保护；2. The terminal SIM card password protection method, that is, when the mobile terminal detects that the inserted SIM card has changed, the user needs to enter the password. protection of content data;

3、OMA DM软件升级方式。开放移动联盟(Open Mobile Alliance，简称OMA)成立于2002年6月，其成员包括世界主要的移动运营商，设备和网络供应商，信息技术公司，应用发展商和内容提供商，OMA的宗旨是寻求一种与系统无关的、开放的，使各种应用和业务能够在全球范围内的各种终端上实现互联互通的标准；设备管理(Device Management，简称DM)就是OMA定义的一系列涉及设备管理的通信协议和数据对象定义机制，DM可以实现运营商对附着在其无线网络上的移动终端进行参数配置与查询及固件/软件更新下载等管理操作。利用该方法，移动通信网络可以在接收到移动终端的遗失报告时，下发锁定该终端的软件到该移动终端上，从而避免该移动终端被盗用。3. OMA DM software upgrade method. The Open Mobile Alliance (OMA) was established in June 2002. Its members include the world's major mobile operators, equipment and network suppliers, information technology companies, application developers and content providers. The purpose of OMA is to Seeking a system-independent and open standard that enables various applications and services to realize interconnection and intercommunication on various terminals around the world; Device Management (DM for short) is a series of related equipment defined by OMA. With the management communication protocol and data object definition mechanism, DM can realize management operations such as parameter configuration and query, firmware/software update download, etc. for mobile terminals attached to its wireless network. By using the method, the mobile communication network can deliver the software for locking the terminal to the mobile terminal when receiving the loss report of the mobile terminal, thereby preventing the mobile terminal from being stolen.

但上述三种方法都不能做到有效地防止丢失或被盗的移动终端被盗用，这是因为：But above-mentioned three kinds of methods all can not accomplish effectively to prevent that lost or stolen mobile terminal is embezzled, and this is because:

对于终端开机密码保护方法而言，拾获或盗窃该移动终端的人，完全可以通过使用同型号的充电器实现长期不关机并盗打使用；即使担心受到法律制裁而不得不关机逃避，也有足够的时间在关机之前盗取移动终端中的个人信息，造成用户信息泄露；For the terminal power-on password protection method, the person who picks up or steals the mobile terminal can use the charger of the same type to realize long-term non-shutdown and stealing; Steal personal information in the mobile terminal before shutting down, resulting in leakage of user information;

对于终端SIM卡密码保护方法而言，由于可以在不更换SIM卡的前提下继续使用该移动终端，因此同样存在上述问题，造成用户经济损失或隐私泄露；For the terminal SIM card password protection method, since the mobile terminal can continue to be used without changing the SIM card, the above-mentioned problems also exist, resulting in economic loss or privacy disclosure of the user;

对于OMA DM软件升级方式而言，由于有网络侧服务器进行控制，因此反应速度较快；但是，OMA DM软件升级方式是通过查找登记终端的SIM卡实现阻止，当拾获或盗窃该移动终端的人更换其中的SIM卡时，就不能找到该移动终端并实现锁止，因此同样避免不了用户的隐私泄露问题。For the OMA DM software upgrade method, the reaction speed is faster due to the control of the network side server; however, the OMA DM software upgrade method is prevented by searching the SIM card of the registered terminal. When a person changes the SIM card therein, the mobile terminal cannot be found and locked, so the user's privacy disclosure problem cannot be avoided equally.

综上所述，目前还没有一种技术方案，能够使得移动终端在任何情况下都不会泄露内容数据和相关信息，也拒绝他人使用该移动终端。To sum up, there is currently no technical solution that can prevent the mobile terminal from divulging content data and related information under any circumstances and deny others from using the mobile terminal.

具体实施方式Detailed ways

由于国际移动设备识别(International Mobile Equipment Identifier)信息能够在SIM卡更换后首次开机时，和SIM卡信息一起，被移动终端自动上报给网络侧服务器，因此，移动终端的IMEI与当前插入该终端的SIM卡的匹配信息能够被网络侧服务器查询得到。本发明基于上述特点，提供了一种实现移动终端数据保护的方法。Since the International Mobile Equipment Identifier (IMI) information can be automatically reported to the network side server by the mobile terminal together with the SIM card information when the SIM card is switched on for the first time, the IMEI of the mobile terminal is the same as the one currently inserted into the terminal. The matching information of the SIM card can be obtained by querying the network side server. Based on the above features, the present invention provides a method for realizing data protection of a mobile terminal.

参见图1，是本发明中实现移动终端数据保护的系统示意图，由移动终端、网络侧服务器以及数据库构成。Referring to FIG. 1 , it is a schematic diagram of a system for realizing data protection of a mobile terminal in the present invention, which is composed of a mobile terminal, a network-side server and a database.

该数据库可以使网络侧所特别设置的专有数据库，也可以是服务器中集成的数据库，用于保存并更新移动终端上报的IMEI及SIM卡配对信息。The database can be a proprietary database specially set by the network side, or a database integrated in the server, which is used to save and update the IMEI and SIM card pairing information reported by the mobile terminal.

网络侧服务器在接收到一移动终端A的遗失报告时，能够立刻读取该遗失报告中提供的IMEI信息，然后在数据库中查询对应该IMEI信息的SIM卡信息。When the network side server receives the loss report of a mobile terminal A, it can immediately read the IMEI information provided in the loss report, and then query the SIM card information corresponding to the IMEI information in the database.

或者，网络侧服务器在接收到一移动终端A的遗失报告时，该遗失报告中提供了移动终端A遗失时的SIM卡信息，而非IMEI信息，则网络侧服务器首先查询数据库，获知与该SIM卡信息对应的全部IMEI信息，在遗失时间之前的IMEI信息对应的为移动终端A的IMEI信息。网络侧服务器通过数据库中查询对应该IMEI信息的当前SIM卡信息。Or, when the network side server receives the loss report of a mobile terminal A, the SIM card information when the mobile terminal A is lost is provided in the loss report instead of the IMEI information, then the network side server first inquires the database and learns that the SIM card is related to the SIM card. All the IMEI information corresponding to the card information, the IMEI information before the lost time corresponds to the IMEI information of the mobile terminal A. The network side server queries the current SIM card information corresponding to the IMEI information through the database.

其中，遗失报告由移动终端A的机主用户通过IP网或者移动通信网或者固定电话网通知网络侧服务器，为了保证不为其他人任意上报遗失报告，可以采取以下措施：Among them, the loss report is notified by the owner user of the mobile terminal A to the network side server through the IP network, mobile communication network or fixed telephone network. In order to ensure that the loss report is not arbitrarily reported for others, the following measures can be taken:

在每一移动终端第一次启动时，发送一个识别码给该移动终端并提醒机主用户保存，上报遗失报告的用户必须提供该识别码；When each mobile terminal is started for the first time, send an identification code to the mobile terminal and remind the owner user to save, and the user who reports the loss report must provide the identification code;

或者，在每一移动终端第一次启动时，提醒机主用户在指定网络上进行防盗注册，上报遗失报告的用户必须提供相应注册信息。Or, when each mobile terminal is started for the first time, the owner user is reminded to perform anti-theft registration on the designated network, and the user who reports the loss report must provide corresponding registration information.

或者，其它可以验证上报遗失报告用户机主身份的方式。Or, other methods that can verify the identity of the owner of the user who reported the loss.

如果遗失报告上报及时，网络侧服务器就可以在第一时间调取移动终端A的IMEI信息和SIM卡信息，根据该SIM卡信息下发锁止软件，避免用户信息泄露和盗用。If the loss report is reported in time, the network side server can retrieve the IMEI information and SIM card information of mobile terminal A at the first time, and issue locking software according to the SIM card information to avoid user information leakage and embezzlement.

其中，上述IMEI信息和SIM卡信息根据以下几种情况有所不同：Among them, the above-mentioned IMEI information and SIM card information are different according to the following situations:

1、移动终端A未曾更换SIM卡，且目前开机：则不会有新的匹配信息上报给数据库，网络侧服务器读取到IMEI信息后，根据该IMEI信息得到的是原有SIM卡号1234567890，则网络侧服务器按照1234567890直接将锁止软件发送给移动终端A；1. Mobile terminal A has not changed the SIM card and is currently powered on: no new matching information will be reported to the database. After the network side server reads the IMEI information, the original SIM card number 1234567890 is obtained according to the IMEI information, then The network side server directly sends the locking software to mobile terminal A according to 1234567890;

2、移动终端A更换过SIM卡，且曾经开机：则在开机的同时，移动终端A的IMEI信息和新的SIM卡信号0123456789就被上报给数据库，网络侧服务器读取到IMEI信息后，根据该IMEI信息得到的是新的SIM卡号0123456789。如果当前该移动终端A开机，则网络侧服务器按照0123456789直接将锁止软件发送给移动终端A；否则，等待该移动终端A开机后，按照0123456789将锁止软件发送给移动终端A；2. The mobile terminal A has changed the SIM card, and has been turned on: at the same time as the mobile terminal A is turned on, the IMEI information of the mobile terminal A and the new SIM card signal 0123456789 are reported to the database. After the network side server reads the IMEI information, according to The IMEI information obtained is the new SIM card number 0123456789. If the mobile terminal A is currently turned on, the network side server will directly send the locking software to the mobile terminal A according to 0123456789; otherwise, after waiting for the mobile terminal A to turn on, send the locking software to the mobile terminal A according to 0123456789;

3、移动终端A当前关机，且未曾在更换过SIM卡的情况下开机：如果其更换了SIM卡，则只要开机时就会上报IMEI和SIM卡的匹配信息并被锁止；如果未更换SIM卡，则将在开机时直接被锁止。3. The mobile terminal A is currently shut down, and has never been turned on after changing the SIM card: if it has changed the SIM card, it will report the matching information of the IMEI and the SIM card and be locked as long as it is turned on; if the SIM card has not been changed card, it will be locked directly at power-on.

可见，无论哪一种情况，都能有效地保护移动终端A的机主用户信息不被泄漏。It can be seen that no matter what the situation is, the owner user information of the mobile terminal A can be effectively protected from being leaked.

进一步的，如果移动终端A遗失时对应的SIM卡信息被查询得到，同样通过根据SIM卡信息锁止终端的方法，锁止遗失SIM卡当前所在终端，则可以防止遗失SIM卡不会被盗用，保护了用户的经济利益。Further, if the corresponding SIM card information is queried when the mobile terminal A is lost, similarly by locking the terminal according to the SIM card information, the terminal where the lost SIM card is currently located can be locked to prevent the lost SIM card from being stolen. The economic interests of users are protected.

同时，本领域技术人员应当理解，如果数据库中所保存的不仅仅是IMEI信息与SIM卡信息的对应关系，还包括其它移动终端的识别信息与SIM卡信息的对应关系，则一样可以通过查询移动终端的其它识别信息，实现对移动终端当前SIM卡信息的确定。At the same time, those skilled in the art should understand that if the database stores not only the corresponding relationship between IMEI information and SIM card information, but also the corresponding relationship between identification information of other mobile terminals and SIM card information, then you can also query mobile Other identification information of the terminal is used to determine the current SIM card information of the mobile terminal.

本发明提供了一种实现移动终端数据保护的方法，如图2所示，包括以下步骤：The present invention provides a kind of method that realizes mobile terminal data protection, as shown in Figure 2, comprises the following steps:

步骤1、网络侧服务器接收到针对一移动终端的遗失报告；Step 1. The network side server receives a loss report for a mobile terminal;

步骤2、网络侧服务器根据所述遗失报告中提供的信息，在网络侧查询所述移动终端当前SIM卡信息；Step 2, the network side server queries the current SIM card information of the mobile terminal at the network side according to the information provided in the loss report;

步骤3、网络侧服务器根据查询到的当前SIM卡信息，将锁定软件发送给所述移动终端；Step 3, the network side server sends the locking software to the mobile terminal according to the inquired current SIM card information;

步骤4、接收到锁定软件的移动终端自动运行所述锁定软件，执行锁定所述移动终端的操作。Step 4. The mobile terminal that receives the locking software automatically runs the locking software, and executes the operation of locking the mobile terminal.

其中，步骤1之前还包括将所述任一移动终端自动上报的IMEI信息及对应SIM卡信息保存到数据库中，具体为：Wherein, beforestep 1, it also includes saving the IMEI information and the corresponding SIM card information automatically reported by any mobile terminal into the database, specifically:

网络侧服务器在任一移动终端更新SIM卡后启动时，接收并将所述任一移动终端自动上报的IMEI信息及对应SIM卡信息以及接收的时间信息保存到数据库中；并将对应最后一次时间信息的IMEI信息及对应SIM卡信息作为所述移动终端当前的IMEI信息及对应SIM卡信息。When the network side server starts after any mobile terminal updates the SIM card, it receives and stores the IMEI information and corresponding SIM card information and received time information automatically reported by any mobile terminal into the database; and the corresponding last time information The IMEI information and corresponding SIM card information of the mobile terminal are used as the current IMEI information and corresponding SIM card information of the mobile terminal.

即在本发明所提供的实现移动终端数据保护的方法中，SIM卡更换或者未被更换时，网络侧服务器将相应获取不同的SIM信息，如下：That is, in the method for realizing data protection of a mobile terminal provided by the present invention, when the SIM card is replaced or not replaced, the network side server will obtain different SIM information accordingly, as follows:

当所述移动终端首次启动以及更换SIM卡时，所述网络侧服务器接收并将所述移动终端自动上报的IMEI信息及对应SIM卡信息保存到数据库中。When the mobile terminal is started for the first time and the SIM card is replaced, the network side server receives and saves the IMEI information and the corresponding SIM card information automatically reported by the mobile terminal into the database.

则如果移动终端遗失后未曾更换SIM卡，则预先存储的IMEI信息及对应的SIM卡信息就是移动终端最后一次由机主更换SIM卡时上报的信息。If the SIM card has not been replaced after the mobile terminal is lost, the pre-stored IMEI information and corresponding SIM card information are the information reported when the mobile terminal was last replaced by the owner of the SIM card.

或者，当移动终端遗失后，所述移动终端更换SIM卡并启动时，所述网络侧服务器接收并更新数据库中的所述移动终端自动上报的IMEI信息及对应SIM卡信息。Or, when the mobile terminal is lost, the mobile terminal replaces the SIM card and starts up, the network side server receives and updates the IMEI information and the corresponding SIM card information automatically reported by the mobile terminal in the database.

参见图3，为存储信息的一个实施例：当原SIM卡号码为1234567890，IMEI号码为XXXXXXYYZZZZZZB的移动终端A第一次开启时，自动上报了其SIM卡号码和IMEI号码的对应关系；该移动终端A遗失后，用户B拾获并将自己的SIM卡换入移动终端A继续使用，换入的SIM卡号码为0123456789；当移动终端A在更换SIM卡后第一次开启时，监测到SIM卡发生了变化，因此，自动上报由IMEI信息XXXXXXYYZZZZZZB及新的SIM卡信息0123456789构成的配对信息，由网络侧服务器在数据库中进行存储。具体的包括以下步骤：Referring to Fig. 3, it is an embodiment of storing information: when the original SIM card number is 1234567890, and the mobile terminal A whose IMEI number is XXXXXXYYZZZZZZB is turned on for the first time, it automatically reports the corresponding relationship between its SIM card number and the IMEI number; After terminal A is lost, user B picks up and replaces his SIM card into mobile terminal A to continue using. The number of the replaced SIM card is 0123456789; when mobile terminal A turns on for the first time after replacing the SIM card, it detects that The card has changed. Therefore, the pairing information composed of IMEI information XXXXXXYYZZZZZZB and new SIM card information 0123456789 is automatically reported, and stored in the database by the network side server. Specifically, the following steps are included:

步骤11、移动终端A启动；Step 11, mobile terminal A starts;

步骤12、移动终端A检测SIM卡是否发生变化，是则执行步骤12，否则结束；Step 12, mobile terminal A detects whether the SIM card has changed, if yes, executestep 12, otherwise end;

步骤13、移动终端A读取新的SIM卡信息；Step 13, mobile terminal A reads new SIM card information;

步骤14、移动终端A自动将IMEI信息XXXXXXYYZZZZZZB及新的SIM卡信息0123456789一起上报给网络侧服务器；Step 14, mobile terminal A automatically reports the IMEI information XXXXXXYYZZZZZZB and the new SIM card information 0123456789 to the network side server;

步骤15、网络侧服务器在数据库中保存该配对信息，并记录保存时间；Step 15, the network side server saves the pairing information in the database, and records the saving time;

步骤16、网络侧服务器将对应最后一次时间信息的IMEI信息及对应SIM卡信息作为移动终端A当前的IEMI信息及对应SIM卡信息。。Step 16, the network side server uses the IMEI information corresponding to the last time information and the corresponding SIM card information as the current IEMI information and corresponding SIM card information of the mobile terminal A. .

此时，数据库中实际保存了两组对应关系：XXXXXXYYZZZZZZB与1234567890，以及XXXXXXYYZZZZZZB与0123456789，而根据更新时间，当前的IMEI信息及对应的SIM卡信息为XXXXXXYYZZZZZZB与0123456789。At this time, two sets of corresponding relationships are actually saved in the database: XXXXXXYYZZZZZZB and 1234567890, and XXXXXXYYZZZZZZB and 0123456789. According to the update time, the current IMEI information and the corresponding SIM card information are XXXXXXYYZZZZZZB and 0123456789.

当所述遗失报告提供有所述移动终端的IMEI信息时，所述步骤2具体为：When the loss report is provided with the IMEI information of the mobile terminal, thestep 2 is specifically:

步骤21、网络侧服务器从所述遗失报告中读取所述移动终端的IMEI信息；Step 21, the network side server reads the IMEI information of the mobile terminal from the loss report;

步骤22、网络侧服务器在存储有IMEI信息及对应SIM卡信息的数据库中，查询该IMEI信息对应的SIM卡信息。Step 22, the network side server queries the SIM card information corresponding to the IMEI information in the database storing the IMEI information and the corresponding SIM card information.

当所述遗失报告提供有所述移动终端的SIM卡信息时，所述步骤2具体为：When the SIM card information of the mobile terminal is provided in the loss report, thestep 2 is specifically:

步骤21′、网络侧服务器从所述遗失报告中读取所述移动终端的SIM卡信息；Step 21', the network side server reads the SIM card information of the mobile terminal from the loss report;

步骤22′、网络侧服务器在存储有IMEI信息及对应SIM卡信息的数据库中，读取遗失时间之前所述SIM卡信息对应的IMEI信息；Step 22', the network side server reads the IMEI information corresponding to the SIM card information before the lost time in the database storing the IMEI information and the corresponding SIM card information;

步骤23′、网络侧服务器再次在存储有IMEI信息及对应SIM卡信息的数据库中，读取当前所述IMEI信息对应的SIM卡信息。Step 23', the network side server reads the SIM card information corresponding to the current IMEI information again from the database storing the IMEI information and the corresponding SIM card information.
