本发明实施例涉及移动终端技术领域，尤其涉及一种移动终端的锁定方法及系统。
背景技术
随着社会的不断发展和进步，智能手机越来越普遍，而且在生活中占有的地位也越来越重要。智能手机的各个功能中，查找手机绝对是一个重要且非常有用的功能，如果智能手机丢失，可以使用查找手机功能将丢失的智能手机锁定，即使其他人拾到智能手机，也无法使用。
然而，一般厂商的查找手机功能具有局限性，即智能手机锁定后，直接对智能手机烧写该厂商的手机只读内存镜像(ROM image，ROM)，会对智能手机解除锁定，通过这种方法，绕开了智能手机的锁定功能，让用户失去了对智能手机的控制。
发明内容
本发明实施例提供一种移动终端的锁定方法及系统，用以解决智能手机可以通过烧写ROM，从而解除锁定的问题。
本发明实施例提供一种移动终端的锁定方法，应用于移动终端，包括：
在所述移动终端每次启动时，向服务器发送锁定状态查询请求；所述服务器上存储有所述移动终端的锁定状态信息；
将所述服务器返回的锁定状态信息与所述移动终端当前的锁定状态信息进行比对；
若所述服务器返回的锁定状态信息表示锁定状态，且所述移动终端当前的锁定状态信息表示解锁状态，则对所述移动终端进行锁定操作。
相应地，本发明实施例还提供一种移动终端的锁定系统，包括：移动终端和服务器；其中，所述服务器上存储有所述移动终端的锁定状态信息；所述移动终端包括：

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2为本发明实施例二中的一种智能手机的锁定方法的步骤流程图；
图3为本发明实施例三中的一种移动终端的锁定系统的结构示意图；
图4示意性地示出了用于执行根据本发明的方法的移动终端的框图；以及

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
详细介绍本发明实施例一提出的一种移动终端的锁定方法，应用于移动终端，本发明实施例中的移动终端可以为智能移动终端，例如，智能手机、平板电脑等。
参照图1，示出了本发明实施例一中的一种移动终端的锁定方法的步骤流程图。
步骤100，在所述移动终端每次启动时，向服务器发送锁定状态查询请 求。
所述移动终端每次启动，包括移动终端烧写ROM后的启动。所述服务器上存储有所述移动终端的锁定状态信息。其中，锁定状态信息用于表示移动终端处于锁定状态还是解锁状态。服务器上可以存储至少一个移动终端的锁定状态信息，若服务器上存储有多个移动终端的锁定状态信息，则每条锁定状态信息与每个移动终端具有一一对应关系，即一个移动终端对应一条锁定状态信息。本发明实施例中的锁定状态信息可以以字符或者字符串的形式存储在服务器中，例如，“1”表示移动终端处于锁定状态，“0”表示移动终端处于解锁状态。
在本发明的一个优选的实施例中，在向服务器发送锁定状态查询请求之前，还需要移动终端建立与服务器的网络连接。具体地，注册网络广播(CONNECTIVITY_ACTION)监听器，监听移动终端的网络连接状态。收到CONNECTIVITY_ACTION后，确认网络连接状态为已连接(CONNECTED)，则移动终端建立与服务器之间的网络连接。
步骤102，将所述服务器返回的锁定状态信息与所述移动终端当前的锁定状态信息进行比对。
移动终端的处于锁定状态或者解锁状态均可以通过移动终端中的锁定状态信息表示。该表示形式与服务器中的移动终端的锁定状态信息的表示形式相同。通过将服务器返回的锁定状态信息与移动终端当前的锁定状态信息进行比对，可以判断服务器存储的移动终端的锁定状态与移动终端当前的锁定状态是否相同。
步骤104，若所述服务器返回的锁定状态信息表示锁定状态，且所述移动终端当前的锁定状态信息表示解锁状态，则对所述移动终端进行锁定操作。
当服务器存储的移动终端的锁定状态(remote_lock_state)与移动终端当前的锁定状态(local_lock_state)不同时，具体地，当服务器返回的锁定状态信息表示锁定状态，且移动终端当前的锁定状态信息表示解锁状态时，以服 务器存储的移动终端的锁定状态为准，将移动终端当前的解锁状态更改为锁定状态。具体可以利用系统用户界面(SystemUI)模块对移动终端进行锁定操作。
当所述服务器上存储的所述移动终端的锁定状态信息表示锁定状态时，所述服务器上还存储有所述移动终端的锁定密码信息。当服务器上存储有多个移动终端的表示锁定状态的锁定状态信息时，服务器上还存储有与多个移动终端一一对应的锁定密码信息。
步骤104中对移动终端进行锁定操作可以利用从服务器获取到的锁定密码信息进行锁定操作。
综上所述，本发明实施例中的技术方案，在移动终端每次启动时，向存储有移动终端的锁定状态信息的服务器发送锁定状态查询请求，接收到服务器返回的锁定状态信息之后，利用接收到的锁定状态信息与移动终端当前的锁定状态信息进行比对，如果接收到的锁定状态信息表示锁定状态，移动终端当前的锁定状态信息表示解锁状态，即服务器上存储的移动终端的锁定状态与移动终端当前的锁定状态不一致，以服务器上存储的锁定状态为准，将所述移动终端锁定。即使通过对移动终端烧写ROM而解除移动终端的锁定状态，在移动终端启动时，也会根据服务器上存储的锁定状态对移动终端进行锁定，避免了通过烧写ROM的方式对移动终端解除锁定，提高了移动终端的安全性。
实施例二
详细介绍本发明实施例二提出的一种移动终端的锁定方法，应用于移动终端，本发明实施例中的移动终端可以为智能移动终端，例如，智能手机、平板电脑等。下面以智能手机为例介绍本发明实施例。
参照图2，示出了本发明实施例二中的一种智能手机的锁定方法的步骤流程图。
步骤200，通过web方式登录到服务器，在查找设备功能中输入智能手机的锁定密码。
本发明实施例中的智能手机为用户A的智能手机，若智能手机丢失，用户A可以通过上述步骤200在服务器中设置智能手机的锁定状态。
步骤202，智能手机接收到服务器的锁定指令，依据锁定指令和锁定密码设置为锁定状态。
步骤204，对智能手机烧写ROM，智能手机的锁定状态解除，变更为解锁状态，同时，智能手机重新启动。
上述步骤204可以为智能手机在丢失的情况下，由用户B对智能手机烧写ROM。
步骤206，智能手机连接到网络，向服务器查询锁定状态。
所述网络可以为移动网络，如运营商的网络，或者可以为无线局域网，本发明实施例对智能手机连接到的网络不做限制，只需要满足与服务器建立连接即可。
步骤208，将服务器上存储的锁定状态与智能手机当前的锁定状态对比，如果服务器上为锁定状态，智能手机为解锁状态，则利用服务器上的锁定密码对智能手机进行锁定。
综上所述，本发明实施例中的技术方案，在移动终端每次启动时，向存储有移动终端的锁定状态信息的服务器发送锁定状态查询请求，接收到服务器返回的锁定状态信息之后，利用接收到的锁定状态信息与移动终端当前的锁定状态信息进行比对，如果接收到的锁定状态信息表示锁定状态，移动终端当前的锁定状态信息表示解锁状态，即服务器上存储的移动终端的锁定状态与移动终端当前的锁定状态不一致，以服务器上存储的锁定状态为准，将所述移动终端锁定。即使通过对移动终端烧写ROM而解除移动终端的锁定状态，在移动终端启动时，也会根据服务器上存储的锁定状态对移动终端进行锁定，避免了通过烧写ROM的方式对移动终端解除锁定，提高了移动终 端的安全性。
实施例二
详细介绍本发明实施例三提出的一种移动终端的锁定系统。
参照图3，示出了本发明实施例三中的一种移动终端的锁定系统的结构示意图。所述系统可以包括移动终端和服务器。本发明实施例中的移动终端可以为智能移动终端，例如，智能手机、平板电脑等。所述服务器上存储有所述移动终端的锁定状态信息。当所述服务器上存储的所述移动终端的锁定状态信息表示锁定状态时，所述服务器上还存储有所述移动终端的锁定密码信息。
所述移动终端可以包括：查询模块30、比对模块32和锁定模块34。
下面分别详细介绍各模块的功能以及各模块之间的关系。
查询模块30，用于在所述移动终端每次启动时，向所述服务器发送锁定状态查询请求。
比对模块32，用于将所述服务器返回的锁定状态信息与所述移动终端当前的锁定状态信息进行比对。
锁定模块34，用于若所述服务器返回的锁定状态信息表示锁定状态，且所述移动终端当前的锁定状态信息表示解锁状态，则对所述移动终端进行锁定操作。
所述移动终端还包括：获取模块，用于在所述锁定模块34对所述移动终端进行锁定操作之前，从所述服务器获取所述移动终端的锁定密码信息。
所述锁定模块34利用所述锁定密码信息对所述移动终端进行锁定操作。
所述移动终端还包括：连接模块，用于在所述查询模块30向所述服务器发送锁定状态查询请求之前，建立所述移动终端的网络连接。
综上所述，本发明实施例中的技术方案，在移动终端每次启动时，向存储有移动终端的锁定状态信息的服务器发送锁定状态查询请求，接收到服务 器返回的锁定状态信息之后，利用接收到的锁定状态信息与移动终端当前的锁定状态信息进行比对，如果接收到的锁定状态信息表示锁定状态，移动终端当前的锁定状态信息表示解锁状态，即服务器上存储的移动终端的锁定状态与移动终端当前的锁定状态不一致，以服务器上存储的锁定状态为准，将所述移动终端锁定。即使通过对移动终端烧写ROM而解除移动终端的锁定状态，在移动终端启动时，也会根据服务器上存储的锁定状态对移动终端进行锁定，避免了通过烧写ROM的方式对移动终端解除锁定，提高了移动终端的安全性。

例如，图4示出了可以实现根据本发明的移动终端。该移动终端传统上包括处理器410和以存储器420形式的计算机程序产品或者计算机可读介质。存储器420可以是诸如闪存、EEPROM(电可擦除可编程只读存储器)、EPROM、硬盘或者ROM之类的电子存储器。存储器420具有用于执行上述方法中的任何方法步骤的程序代码431的存储空间430。例如，用于程序代 码的存储空间430可以包括分别用于实现上面的方法中的各种步骤的各个程序代码431。这些程序代码可以从一个或者多个计算机程序产品中读出或者写入到这一个或者多个计算机程序产品中。这些计算机程序产品包括诸如硬盘，紧致盘(CD)、存储卡或者软盘之类的程序代码载体。这样的计算机程序产品通常为如参考图5所述的便携式或者固定存储单元。该存储单元可以具有与图4的移动终端中的存储器420类似布置的存储段、存储空间等。程序代码可以例如以适当形式进行压缩。通常，存储单元包括计算机可读代码431’，即可以由例如诸如410之类的处理器读取的代码，这些代码当由移动终端运行时，导致该移动终端执行上面所描述的方法中的各个步骤。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
