随着智能终端和网络的飞速发展，终端(包括电脑、手机、平板等多种设备)在人们生活中扮演的角色也越来越重要，越来越成为人们工作和生活中不可或缺的全方位“助手”。为方便使用，人们在使用终端的应用时通常会将各种账号信息、私人聊天记录以及图片照片等信息直接存储在终端。因此，若终端丢失，不仅会给用户带来财产损失，更为重要的是用户存储于终端内的私人信息，例如账号密码等财务信息。这些私人信息若被泄露，对用户造成的损失难以估计。
现实中，丢失的终端很可能被人不合法地出售给用户；而用户在购买终端时却不能确定终端是否为合法出售的终端。因为，现有技术缺乏有效的方法来确定终端的状态。偷盗者利用现有技术的缺陷将赃物(偷盗的手机等终端)出售给用户。这种技术缺陷导致偷盗者很容易将被盗终端出售，进一步促进了不法行为的发生。
另一方面，为了防止丢失终端中的私人信息不被泄露，终端的防盗十分重要。现有技术中，终端的防盗方法主要通过锁定移动设备屏幕实现。图1示出了现有技术中手机防盗输入验证信息的界面示意图。如图1所示，手机被盗之后，出现界面提示手机已开启防盗功能，用户需要输入验证信息才能够对手机屏幕进行解锁。如图1中，用户需要输入开头为138的亲友号码对手机进行解锁。当解锁失败，如图1所示，手机在界面提示解锁发起者解锁失败，请等待机主联系。另外，手机无法解锁时，也无法开启其中的应用。现有技术中，只有当被盗手机多次解锁失败(例如3次)，才会进行对解锁发起者进行拍照取证。
并且，在现有技术中，若解锁失败，终端防盗界面通常会出现警示语，提示本终端处于被盗状态。偷盗者根据这些警示语会提高警惕，并且由于不知道解锁验证信息，可能放弃输入验证码解锁，甚至可能直接取出电池保证自己不会被追踪。
由上述现有技术可知，现有的终端防盗方法会增加偷盗者的警惕程度，利用终端自身进行拍照取证的时间间隔较长，相应增加了终端寻回的难度以及终端被盗的破案难度。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决或者减缓上述问题的终端状态查询方法、终端防盗方法及相应的设备。
依据本发明的一个方面，本发明提供了一种终端状态的查询方法，包括：发送查询请求至服务器，查询指定终端的状态信息，其中，所述查询请求中携带有所述指定终端的身份标识信息；接收所述服务器返回的查询结果，其中，所述服务器中存储有所述指定终端的状态信息，所述服务器接收到所述查询请求时根据所述身份标识信息在已存储的状态信息中进行查询，获得所述查询结果；根据所述查询结果确定所述指定终端的当前状态。

具体实施方式
下面结合附图和具体的实施方式对本发明作进一步的描述。
相关技术中提及，无法确定终端的状态信息，因此，导致用户容易购买被盗终端，促进偷盗终端的不法行为，产生恶劣后果。
为解决上述技术问题，本发明实施例提供了一种终端状态的查询方法。图2示出了根据本发明一个实施例的一种终端状态的查询方法的处理流程图。如图2所示，该流程至少包括步骤S202至步骤S206。
步骤S202、发送查询请求至服务器，查询指定终端的状态信息，其中，查询请求中携带有指定终端的身份标识信息。
步骤S204、接收服务器返回的查询结果，其中，服务器中存储有指定终端的状态信息，服务器接收到查询请求时根据身份标识信息在已存储的状态信息中进行查询，获得查询结果。
步骤S206、根据查询结果确定指定终端的当前状态。
本发明实施例的终端状态的查询方法中，发送查询请求至服务器，查询指定终端的状态信息，并根据接收到的服务器返回的查询结果确定终端的当前状态，能够解决现有技术中无法确定终端的当前状态的问题。例如，采用本发明实施例，若偷盗者对被盗终端进行交易，购买者能够查询到终端被盗，进而停止交易并提供偷盗者的线索，甚至将被盗终端归还失主。因此，采用本发明实施例能够达到避免购买被盗终端，增加被盗终端的找回机率，并有效遏制偷盗行为的有益效果。
本发明实施例中，执行如图2所示的步骤S202之前，获取需要查询的终端的身份标识信息。获取到身份标识信息之后，本发明实施例执行如图2所示的步骤S202，发送携带有指定终端的身份标识信息的查询请求至服务器，查询指定终端的状态信息。
本发明实施例中，终端的身份标识信息可以是终端的国际移动设备身份识别码(International Mobile Equipment Identity，以下简称IMEI)，可以是终端的用户身份标识码(Identity，以下简称ID)，还可以是任意能够唯一标识终端的身份标识信息，本发明实施例对此并不加以限定。为提高终端的安全性，确定服务器接收到的查询请求为通过合法性验证的查询请求。优选地，本发明实施例提供一种终端身份标识。该终端身份标 识为终端的硬件ID。
现对该硬件ID的获取进行具体介绍。如上文所述，本发明实施例发送查询请求之前，获取上述硬件ID。本发明实施例首先获取终端的IMEI，记为第一字符串。其次，本发明实施例获取被盗移动终端的网卡地址，并去除网卡地址中的非字母以及非数字字符，去除后的网卡地址记为第二字符串。获取到第一字符串以及第二字符串之后，本发明实施例获取终端的中央处理器(Central Processing Unit，以下简称CPU)串号，记为第三字符串。获取到第一、第二以及第三字符串之后，本发明实施例按预定顺序合并上述三个字符串。其中，该预定顺序可以是按第一、第二、第三的顺序合并上述三个字符串，可以是按第三、第二、第一的倒序合并上述三个字符串，还可以是其他预定的顺序，本发明实施例对此并不加以限定。
合并上述字符串之后，本发明实施例将合并后得到的结果转换为大写格式，并记为第一结果。获取到第一结果之后，本发明实施例继续将该第一结果进行消息摘要算法第五版(Message Digest Algorithm 5，以下简称MD5)运算，得到第二结果。之后，本发明实施例将该第二结果转换为大写格式得到终端的硬件ID。
本发明实施例中终端的硬件ID通过将终端的IMEI、网卡地址以及CPU的串号进行合并运算能够保证服务器接收的查询请求是真实有效可信的，避免接收来自不可信或恶意发送端伪装成可信任方发送的查询请求导致服务器返回终端的状态信息至恶意发送端，泄露终端的状态信息。
如上文所述，本发明实施例发送携带有终端的身份标识信息的查询请求至服务器。服务器接收到查询请求之后，根据查询请求中携带的身份标识信息对该查询请求进行合法性验证。当查询请求通过合法性验证之后，服务器根据查询请求中携带的身份标识信息在本地存储的终端的状态信息中查找到对应的终端的状态信息，并返回查询结果。本发明实施例接收到服务器返回的查询结果之后，根据该查询结果能够确定终端的状态。
本发明实施例中，查询到的终端的状态信息可以包括终端被盗、未被盗或者终端被盗后找回等等。若根据服务器的查询结果，确定终端的当前状态信息为终端被盗，则购买终端者能够立刻停止交易，帮助找到失主，归还手机，并且能够提供偷盗者的线索，帮助抓捕偷盗者，进一步减少盗窃犯罪。进一步，本发明实施例的终端的状态信息还可以包括其他更为详细的说明，例如包括终端未出售、终端使用中以及终端被转卖等终端的出售购买状态信息，还可以是其他任意终端的当前状态信息，本发明实施例对此并不加以限定。
例如，当终端为手机，购买手机时，本发明实施例能够发送查询请求至服务器，并根据服务器返回的查询结果确定当前手机的状态。若手机的状态信息为未被盗，则用户能够购买手机。若手机的状态信息为被盗，则用户能够及时拒绝购买该手机，同时提供偷盗者的线索至相关部门，帮助失主寻回被盗手机。
另外，本发明实施例中，查询请求的发送方可以设置于移动终端，例如手机，笔记本电脑等等，并通过短信息或者网络的形式发送查询请求。本发明实施例中的发送方还 可以设置于终端，例如电脑。当该终端与查询请求中携带的身份标识信息对应的终端之间成功建立连接，能够进行数据传输之后，本发明实施例能够利用该终端通过网络的形式发送上述查询请求。采用本发明实施例，能够及时查询终端的状态信息。例如，当用户购买终端时，首先对该终端的状态信息进行查询，并根据查询结果决定是否购买。若查询到终端不是被盗终端，则用户能够不存在风险地购买该终端。若查询到终端为被盗终端，则用户能够及时停止交易，并将被盗终端归还失主，同时帮助抓捕偷盗者，有效遏制偷窃犯罪的发生。
基于上文各优选实施例提供的终端状态的查询方法，基于同一发明构思，本发明实施例提供另一种终端状态的查询方法。
图3示出了根据本发明一个实施例的另一种终端状态的查询方法的处理流程图。如图3所示，该流程至少包括步骤S302至步骤S306。
步骤S302、接收查询请求，其中，查询请求中携带有指定终端的身份标识信息。
步骤S304、根据查询请求中携带的指定终端的身份标识信息在服务器本地存储的状态信息中对指定终端的状态信息进行查询，获得查询结果。
步骤S306、返回查询结果至查询请求发送方。
本发明实施例接收发送方发送的查询请求，查询指定终端的状态信息，并返回查询结果，由发送方根据接收到的服务器返回的查询结果确定终端的当前状态，能够解决现有技术中无法确定终端的当前状态的问题。例如，采用本发明实施例，若偷盗者对被盗终端进行交易，购买者能够查询到终端被盗，进而停止交易并提供偷盗者的线索，甚至将被盗终端归还失主。因此，采用本发明实施例能够达到避免购买被盗终端，增加被盗终端的找回机率，并有效遏制偷盗行为的有益效果。
如图3所示的步骤S302执行完毕之后，本发明实施例接收到发送方发送的携带有终端身份标识信息的查询请求。为保证服务器接收到的查询请求是真实有效可信的，本发明实施例对接收到的查询请求进行合法性验证。本发明实施例通过对接收到的查询请求进行合法性验证，避免接收来自不可信或恶意发送端发送的查询请求导致服务器查询终端的状态信息并泄露终端的状态信息至不法分子。
本发明实施例中，利用查询请求中携带的终端的身份标识信息对查询请求的合法性进行验证。若查询请求中携带的终端的身份标识信息与服务器本地存储的身份标识信息能够匹配，则查询请求通过合法性验证。若查询请求中携带的终端的身份标识信息与服务器本地存储的身份标识信息不能够匹配，则查询请求不能通过合法性验证。
对查询请求进行合法性验证之后，本发明实施例根据查询请求是否通过合法性验证执行不同的操作。若查询请求未通过合法性验证，本发明实施例忽略该查询请求不执行任何操作。若查询请求通过合法性验证，本发明实施例执行如图3所示的步骤S304，根据查询请求中携带的指定终端的身份标识信息在服务器本地存储的状态信息中对指定终端的状态信息进行查询，获得查询结果。优选地，本发明实施例中以终端的身份标识信息为主键对指定终端的状态信息进行查询。例如，查询请求通过合法性验证之后，本发 明实施例可以以指定终端的IMEI和/或指定终端的用户ID和/或指定终端的硬件ID为主键对终端的状态信息进行查询，保证获得的查询结果为查询请求中指定的终端。之后，本发明实施例继续执行如图3所示的步骤S306，将该查询结果返回至查询请求发送方，由发送方根据该查询结果执行相应操作。例如，若根据查询结果，该终端为被盗终端，则用户能够立即停止交易，提供偷盗者的线索帮助抓获偷盗者，并将被盗终端归还失主。
本发明实施例中，终端的身份标识信息可以是终端的IMEI，可以是终端的用户ID，还可以是终端的硬件ID等任意能够唯一标识终端的身份标识信息，本发明实施例对此并不加以限定。其中，终端的硬件ID为汇集多种终端身份标识信息的、综合的身份标识信息。硬件ID通过将终端的IMEI、网卡地址以及CPU的串号进行合并运算能够保证服务器接收的查询请求是真实有效可信的。若本发明实施例中以硬件ID为身份标识信息对查询请求进行验证，当硬件ID匹配，则终端的IMEI、网卡地址以及CPU串号均能够匹配，则能够确定本发明实施例接收到的查询请求的合法性。

基于上文各优选实施例提供的终端状态的查询方法，基于同一发明构思，本发明实施例提供了一种终端状态的查询客户端，用于实现上述终端状态的查询方法。
图7示出了根据本发明一个实施例的终端状态的查询客户端的结构示意图。参见图7，本发明实施例的终端状态的查询客户端至少包括：发送器720、接收器730以及确定器740。
现介绍本发明实施例的终端状态的查询客户端的各器件或组成的功能以及各部分间的连接关系：
发送器720，配置发送查询请求至服务器，查询指定终端的状态信息，其中，查询请求中携带有指定终端的身份标识信息。
接收器730，与发送器720相耦合，配置为接收服务器返回的查询结果，其中，服务器中存储有指定终端的状态信息，服务器接收到查询请求时根据身份标识信息在已存储的状态信息中进行查询，获得查询结果。
确定器740，与接收器730相耦合，配置为根据查询结果确定指定终端的当前状态。
本发明实施例发送查询请求至服务器，查询指定终端的状态信息，并根据接收到的服务器返回的查询结果确定终端的当前状态，能够解决现有技术中无法确定终端的当前状态的问题。例如，采用本发明实施例，若偷盗者对被盗终端进行交易，购买者能够查询到终端被盗，进而停止交易并提供偷盗者的线索，甚至将被盗终端归还失主。因此，采用本发明实施例能够达到避免购买被盗终端，增加被盗终端的找回机率，并有效遏制偷盗行为的有益效果。
如图7所示，发送器720发送查询请求至服务器之前，获取器710获取终端的身份标识信息。获取器710获取到终端的身份标识信息之后，触发发送器720。发送器720 受到触发，发送携带有终端的身份标识信息的查询请求至服务器。
服务器接收到查询请求之后，根据查询请求中携带的身份标识信息对该查询请求进行合法性验证。当查询请求通过合法性验证之后，服务器根据查询请求中携带的身份标识信息在本地存储的终端的状态信息中查找到对应的终端的状态信息，并返回查询结果。如图7所示的客户端中的接收器730接收服务器返回的查询结果，并由与其耦合的确定器740确定终端的当前状态。例如，当终端为手机，购买手机时，本发明实施例的客户端发送查询请求至服务器，并根据服务器返回的查询结果确定当前手机的状态。若手机的状态信息为未被盗，则用户能够购买手机。若手机的状态信息为被盗，则用户能够及时拒绝购买该手机，同时提供偷盗者的线索至相关部门，帮助失主寻回被盗手机。
本发明实施例中，终端的身份标识信息可以是终端的IMEI，可以是终端的用户ID，还可以是任意能够唯一标识终端的身份标识信息，本发明实施例对此并不加以限定。为提高终端的安全性，确定服务器接收到的查询请求为通过合法性验证的查询请求。优选地，本发明实施例提供一种终端身份标识。该终端身份标识为终端的硬件ID。
现对该硬件ID的获取进行具体介绍。如上文所述，发送器720发送查询请求之前，由获取器710获取上述硬件ID。获取器710首先获取终端的IMEI，记为第一字符串。其次，获取器710获取被盗移动终端的网卡地址，并去除网卡地址中的非字母以及非数字字符，去除后的网卡地址记为第二字符串。获取到第一字符串以及第二字符串之后，获取器710获取终端的CPU串号，记为第三字符串。获取到第一、第二以及第三字符串之后，获取器710预定顺序合并上述三个字符串。其中，该预定顺序可以是按第一、第二、第三的顺序合并上述三个字符串，可以是按第三、第二、第一的倒序合并上述三个字符串，还可以是其他预定的顺序，本发明实施例对此并不加以限定。
合并上述字符串之后，获取器710将合并后得到的结果转换为大写格式，并记为第一结果。获取到第一结果之后，本发明实施例继续将该第一结果进行MD5运算，得到第二结果。之后，获取器710将该第二结果转换为大写格式得到终端的硬件ID。
本发明实施例中终端的硬件ID通过将终端的IMEI、网卡地址以及CPU的串号进行合并运算能够保证服务器接收的查询请求是真实有效可信的，避免接收来自不可信或恶意发送端伪装成可信任方发送的查询请求导致服务器返回终端的状态信息至恶意发送端，泄露终端的状态信息。
本发明实施例中，确定器740根据查询结果确定的终端的状态信息可以包括终端被盗、未被盗或者终端被盗后找回等等。若根据服务器的查询结果，确定器740确定终端的当前状态信息为终端被盗，则购买终端者能够立刻停止交易，帮助找到失主，归还手机，并且能够提供偷盗者的线索，帮助抓捕偷盗者，进一步减少盗窃犯罪。进一步，本发明实施例的终端的状态信息还可以包括其他更为详细的说明，例如包括终端未出售、终端使用中以及终端被转卖等终端的出售购买状态信息，还可以是其他任意终端的当前状态信息，本发明实施例对此并不加以限定。
本发明实施例中，客户端可以设置于移动终端，例如手机，笔记本电脑等等，并通 过短信息或者网络的形式发送查询请求。本发明实施例中的客户端还可以设置于终端，例如电脑。当该客户端所在的终端与查询请求中携带的身份标识信息对应的终端之间成功建立连接，能够进行数据传输之后，本发明实施例能够利用该终端通过网络的形式发送上述查询请求。采用本发明实施例，能够及时查询终端的状态信息。例如，当用户购买终端时，首先对该终端的状态信息进行查询，并根据查询结果决定是否购买。若查询到终端不是被盗终端，则用户能够不存在风险地购买该终端。若查询到终端为被盗终端，则用户能够及时停止交易，并将被盗终端归还失主，同时帮助抓捕偷盗者，有效遏制偷窃犯罪的发生。
基于上文各优选实施例提供的终端状态的查询方法及客户端，基于同一发明构思，本发明实施例还提供了一种服务器，用于实现上述终端状态的查询方法。
图8示出了根据本发明一个实施例的服务器的结构示意图。参见图8，本发明实施例的服务器至少包括：请求接收器810、查询器830以及结果发送器840。
现介绍本发明实施例的服务器的各器件或组成的功能以及各部分间的连接关系：
请求接收器810，配置为接收查询请求，其中，查询请求中携带有指定终端的身份标识信息。
查询器830，与请求接收器810相耦合，配置为根据查询请求中携带的指定终端的身份标识信息在服务器本地存储的状态信息中对指定终端的状态信息进行查询，获得查询结果。
结果发送器840，与查询器830相耦合，配置为返回查询结果至查询请求发送方。
本发明实施例接收发送方发送的查询请求，查询指定终端的状态信息，并返回查询结果，由发送方根据接收到的服务器返回的查询结果确定终端的当前状态，能够解决现有技术中无法确定终端的当前状态的问题。例如，采用本发明实施例，若偷盗者对被盗终端进行交易，购买者能够查询到终端被盗，进而停止交易并提供偷盗者的线索，甚至将被盗终端归还失主。因此，采用本发明实施例能够达到避免购买被盗终端，增加被盗终端的找回机率，并有效遏制偷盗行为的有益效果。
如图8所示的服务器中的请求接收器810接收发送方发送的携带有终端身份标识信息的查询请求。为保证该查询请求是真实有效可信的，避免接收来自不可信或恶意发送端发送的查询请求导致服务器查询终端的状态信息并泄露终端的状态信息至不法分子，请求接收器810触发判断器820对接收到的查询请求进行合法性判断。
判断器820利用查询请求中携带的终端的身份标识信息对查询请求的合法性进行判断。若查询请求中携带的终端的身份标识信息与服务器本地存储的身份标识信息能够匹配，则判断器820判断查询请求通过合法性验证。若查询请求中携带的终端的身份标识信息与服务器本地存储的身份标识信息不能够匹配，则判断器820判断查询请求不能通过合法性验证。
判断器820对查询请求的合法性进行判断之后，若查询请求未通过合法性验证，则服务器忽略该查询请求，不执行任何操作。若查询请求通过合法性验证，则判断器820 触发与其耦合的查询器830。查询器830受到触发之后，根据查询请求中携带的指定终端的身份标识信息在服务器本地存储的状态信息中对指定终端的状态信息进行查询，获得查询结果。优选地，查询器830以终端的身份标识信息为主键对指定终端的状态信息进行查询。例如，查询请求通过合法性验证之后，本发明实施例可以以指定终端的IMEI和/或指定终端的用户ID和/或指定终端的硬件ID为主键对终端的状态信息进行查询，保证获得的查询结果为查询请求中指定的终端。查询器830获得查询结果之后，触发结果发送器840。与查询器830相耦合的结果发送器840将查询结果返回至查询请求发送方，由发送方根据该查询结果执行相应操作。例如，若根据查询结果，该终端为被盗终端，则用户能够立即停止交易，提供偷盗者的线索帮助抓获偷盗者，并将被盗终端归还失主。
本发明实施例中，终端的身份标识信息可以是终端的IMEI，可以是终端的用户ID，还可以是终端的硬件ID等任意能够唯一标识终端的身份标识信息，本发明实施例对此并不加以限定。其中，终端的硬件ID为汇集多种终端身份标识信息的、综合的身份标识信息。硬件ID通过将终端的IMEI、网卡地址以及CPU的串号进行合并运算能够保证服务器接收的查询请求是真实有效可信的。若本发明实施例中以硬件ID为身份标识信息对查询请求进行验证，当硬件ID匹配，则终端的IMEI、网卡地址以及CPU串号均能够匹配，则能够确定本发明实施例接收到的查询请求的合法性。
根据上述任意一个优选实施例或多个优选实施例的组合，本发明实施例能够达到如下有益效果：
本发明实施例发送查询请求至服务器，查询指定终端的状态信息，并根据接收到的服务器返回的查询结果确定终端的当前状态，能够解决现有技术中无法确定终端的当前状态的问题。例如，采用本发明实施例，若偷盗者对被盗终端进行交易，购买者能够查询到终端被盗，进而停止交易并提供偷盗者的线索，甚至将被盗终端归还失主。因此，采用本发明实施例能够达到避免购买被盗终端，增加被盗终端的找回机率，并有效遏制偷盗行为的有益效果。
相关技术中还提及，终端被盗之后，偷盗者根据终端显示界面能够识别出终端已开启防盗功能，则放弃对终端进行解锁，导致无法及时获取偷盗者的可识别信息，进而导致终端被盗后无法找回。
为解决上述技术问题，本发明实施例提供了一种终端防盗方法。图9示出了根据本发明一个实施例的终端防盗方法的处理流程图。如图9所示，该流程至少包括步骤S902至步骤S904。
步骤S902、确定终端被盗时，生成无密码屏幕锁屏界面并显示。
步骤S904、接收解锁指令时，拒绝屏幕解锁操作，并获取解锁指令发起方的可识别信息。
在本发明实施例中，确定终端被盗时，生成无密码屏幕锁屏界面并显示。偷盗者查看该界面为无密码屏幕锁屏界面时，无法发现终端已开启了防盗功能，会放松警惕直接进行解锁操作。因此，本发明实施例能够延缓现有技术中偷盗者通过终端界面显示发现 终端已开启防盗功能的时间，避免偷盗者进行拔出终端电池、关闭终端等不利于找回被盗终端的操作。依据本发明实施例能够在接收到解锁指令之后，拒绝解锁，并获取解锁指令发起方的可识别信息。因此，采用本发明实施例能够解决现有技术中只有解锁失败之后才能进行拍照取证的问题。本发明实施例能够避免因拍照取证的时间间隔较长，导致错过获取偷盗者可识别信息的最佳时机的问题。本发明实施例能够生成无密码界面使偷盗者放松警惕。当偷盗者对终端进行解锁，本发明实施例能够即时获取到该解锁指令发起方(即偷盗者)的可识别信息，无须等待多次解锁失败后才进行拍照取证，缩短拍照取证时间。因此，根据本发明实施例提供的方法能够增大用户找回终端的可能性，更加合理有效保证用户财产安全。
本发明实施例接收到可信任方发送的被盗通知指令时，确定终端被盗。其中，可信任方可以是服务器，还可以是用户在使用该终端时设置的亲友号码。现以可信任方的身份分别进行说明。
首先，对采用服务器为可信任方进行说明。在本例中，当用户发现终端被盗之后，登陆服务器，在服务器中对终端的状态进行标识，将终端状态修改为被盗。随后，服务器发送被盗指令至终端，告知终端已被盗。
其次，对采用亲友号码为可信任方进行说明。本例中的亲友号码是指与被盗终端绑定的可信任号码，例如通讯录里的常用电话号码、指定白名单号码等等。实施时，由亲友号码发送被盗指令至被盗终端，及时确认终端被盗。
虽然信任方身份不同，所执行的步骤也不同，但是两者在本发明实施例中起到相同的作用，即，确定终端被盗。在确定之后再执行其他操作，避免因发送被盗指令不及时，导致不法分子有机可乘对终端进行刷机等操作导致被盗终端无法找回的恶劣后果。
另外，本发明实施例还能够通过检测到终端的用户身份识别模块(Subscriber Identity Module，以下简称SIM)卡是否被更换，确定终端是否被盗。盗窃者在使用被盗终端时，通常会更换SIM卡，否则容易被追溯到，因此，检测SIM卡是否被更换是确定终端是否被盗的一个有效手段。采用本发明实施例能够保证失主没有发现终端被盗的情况下，及时发现终端被盗，并及时对被盗终端做出相应处理。
本发明实施例确定终端被盗之后，执行如图9所示的步骤S902，生成无密码锁屏界面并显示。显示无密码锁屏界面之后，若接收到解锁指令，执行如图所示的步骤S904，拒绝屏幕解锁操作，并获取解锁指令发起方的可识别信息。本发明实施例中，终端丢失之后进入锁屏状态。当拾到终端者或者偷盗者企图对终端进行屏幕解锁操作，本发明实施例可以获取解锁指令发起方的可识别信息，并生成密码输入界面，提示需要输入正确的密码以对屏幕进行解锁。密码输入界面需要使用者输入密码方能解锁，若终端接收到正确的密码，则本发明实施例进行屏幕解锁操作，若终端接收到错误的密码，则本发明实施例保持屏幕被锁状态。若一次密码输入有误，通常会允许再次输入。若多次密码输入(例如3次以上)均不正确，为保证终端安全性，则可能会在一定时间内禁止密码输入以及其他任何操作。
本发明实施例中，上述解锁指令发起方的可识别信息可以是通过终端能够获取的、解锁指令发起方的任意可识别信息。优选地，本发明实施例中，可以利用终端的前置摄像头对解锁指令发起方进行拍照，获取照片，还可以记录解锁指令发起方的指纹。本发明实施例中获取到的解锁指令发起方的照片或者指纹为每个人特有的。因此，通过本发明实施例获取到的识别信息能够直接、快速并且有效地寻找到被盗终端的拾到者或者偷盗者，保证被盗终端被找回，进而能够减少终端失窃率并降低偷盗犯罪率。
如上文所述，本发明实施例获取到解锁指令发起方的可识别信息之后，本发明实施例可以发送可识别信息至可信任方，还可以保存上述可识别信息等待进一步处理。优选地，本发明实施例获取到可识别信息之后，发送该可识别信息至可信任方，例如服务器或者被盗终端绑定的亲友号码或者其他可信任方，保证被盗用户能够及时获取到偷盗者的可识别信息，并根据该可识别信息抓获偷盗者，找回被盗终端。
另外，需要说明的是，对于不同的终端以及采用不同操作系统的终端，终端默认锁屏界面的布局和元素存在差异。例如，有的终端默认锁屏界面通过按住屏幕中下方的解锁键向四周滑动解锁。再例如，有的终端默认锁屏界面通过从左向右拖动滑块对屏幕进行解锁。不同终端的锁屏界面还有一些布局细节存在差异，例如获取用户当前设置的桌面壁纸图片资源，或者添加桌面时钟空间的具体方式等，均会因不同终端以及终端中不同的操作系统而存在差异。因此，本发明实施例中生成的无密码屏幕的布局会根据不同的终端以及终端中采用的不同操作系统存在差异。
本发明实施例中，根据终端默认锁屏界面的布局和元素，可以生成与终端默认锁屏界面相同的无密码屏幕，还可以生成与终端默认锁屏界面不同的无密码屏幕。本发明实施例优选生成与终端默认锁屏界面相同的无密码屏幕。
生成与终端默认锁屏界面不同的无密码屏幕容易被偷盗者识别出终端开启了防盗功能，导致错过获取偷盗者可识别信息的机会。综上，本发明实施例中优选无密码屏幕与终端默认锁屏界面是相同的，可识别度低，并防止偷盗者识别出终端开启了防盗功能，进而增大找回被盗终端的可能性，高效合理保护用户财产安全。
现对本发明实施例提供的终端防盗方法进行说明。
实施例四
图3示出了根据本发明一个优选实施例的终端防盗方法的处理流程图，用于支持上述终端防盗方法，将上述终端防盗方法阐述得更加清晰易懂。需要说明的是，为将本发明实施例阐述得简洁易懂，本优选实施例中将终端设置为手机进行说明。参见图3，该优选实施例至少包括步骤S1002至步骤S1012。
步骤S1002、手机绑定亲友号。
具体地，用户购买手机后，可以设置一个亲友号，该亲友号可以是用户自己的其他手机号码，还可以是用户的家人或者朋友的手机号码，保证用户手机丢失之后，能够及时使用亲友号发送防盗处理指令至被盗手机。
步骤S1004、接收到亲友号发送的被盗通知指令，确定手机被盗。
当用户发现手机被盗之后，通过步骤S1002中绑定的亲友号发送被盗通知指令至被盗手机。被盗手机接收到亲友号发送的被盗通知指令之后，能够确定手机被盗。
步骤S1006、生成无密码屏幕界面进行显示，等待解锁命令。
手机确定被盗之后，生成与默认锁屏界面相同或相似的无密码屏幕，等待拾到手机者或者偷盗者对手机进行解锁操作。如图11示出了根据本发明一个实施例的手机默认锁屏界面示意图，图12示出了根据本发明一个实施例的无密码屏幕界面示意图。由图11以及图12对比可知，本优选实施例生成的无密码屏幕与默认锁屏界面含有相同的元素。并且，如图11以及图12所示，本优选实施例中生成的无密码屏幕与默认锁屏界面的壁纸为相同壁纸。
步骤S1008、接收到解锁命令，获取可识别信息，提示密码输入。
当手机接收到解锁命令之后，利用终端摄像头对解锁指令发起方进行拍照，获取拾到手机者或者偷盗者的照片，另外，还可以记录解锁指令发起方的指纹，将获取到的可识别信息保存至手机，并生成需要输入密码的屏幕锁屏界面进行显示，提示解锁指令发起方进行密码输入。
步骤S1010、判断密码输入是否正确。
接收到解锁指令发起方输入的密码之后，判断密码输入是否正确，若输入的密码正确，则进行屏幕解锁操作，流程结束。若密码输入错误，则保持屏幕被锁状态，并执行步骤S1012。
步骤S1012、将获取到的可识别信息发送至亲友号。
确认手记被盗之后，本优选实施例发送获取到的可识别信息至亲友号，流程结束。
通过本优选实施例，能够在确定手机被盗的情况下，获取到手机拾到者或者偷盗者的照片和/或指纹，根据照片和/或指纹，能够查找到手机拾到者或者偷盗者，保证用户在手机丢失之后及时找回手机，进一步减少手机失窃率，降低偷盗犯罪。
基于上文各优选实施例提供的终端防盗方法，基于同一发明构思，本发明实施例提供一种终端防盗客户端，用于实现上述终端防盗方法。
图13示出了根据本发明一个实施例的终端防盗客户端的结构示意图。参见图13，本发明实施例的终端防盗客户端的至少包括：防盗触发模块1310、界面显示模块1320以及处理模块1330。
现介绍本发明实施例的终端防盗客户端的各器件或组成的功能以及各部分间的连接关系：
防盗触发模块1310，配置为确定终端被盗时，触发界面显示模块1320。
界面显示模块1320，与防盗触发模块1310相耦合，配置为生成无密码屏幕锁屏界面并显示。
处理模块1330，与界面显示模块1320相耦合，配置为接收解锁指令时，拒绝屏幕解锁操作，并获取解锁指令发起方的可识别信息。
在本发明实施例中，确定终端被盗时，生成无密码屏幕锁屏界面并显示。偷盗者查 看该界面为无密码屏幕锁屏界面时，无法发现终端已开启了防盗功能，会放松警惕直接进行解锁操作。因此，本发明实施例能够延缓现有技术中偷盗者通过终端界面显示发现终端已开启防盗功能的时间，避免偷盗者进行拔出终端电池、关闭终端等不利于找回被盗终端的操作。依据本发明实施例能够在接收到解锁指令之后，拒绝解锁，并获取解锁指令发起方的可识别信息。因此，采用本发明实施例能够解决现有技术中只有解锁失败之后才能进行拍照取证的问题。本发明实施例能够避免因拍照取证的时间间隔较长，导致错过获取偷盗者可识别信息的最佳时机的问题。本发明实施例能够生成无密码界面使偷盗者放松警惕。当偷盗者对终端进行解锁，本发明实施例能够即时获取到该解锁指令发起方(即偷盗者)的可识别信息，无须等待多次解锁失败后才进行拍照取证，缩短拍照取证时间。因此，根据本发明实施例提供的方法能够增大用户找回终端的可能性，更加合理有效保证用户财产安全。
本发明实施例中，如图13所示的防盗触发模块接收到可信任方发送的被盗通知指令时，确定终端被盗。其中，可信任方可以是服务器，还可以是用户在使用该终端时设置的亲友号码。现以可信任方的身份分别进行说明。
首先，对采用服务器为可信任方进行说明。在本例中，当用户发现终端被盗之后，能够登陆服务器，在服务器中确认对终端的状态进行标识，将终端状态修改为被盗。随后，并由服务器发送被盗指令至终端，确认告知终端已被盗。
其次，对采用亲友号码为可信任方进行说明。本例中的亲友号码是指与被盗终端绑定的可信任号码。例如通讯录里的常用电话号码、指定白名单号码等等。实施时，由亲友号码发送被盗指令至终端，及时确认终端被盗。
虽然信任方身份不同，所执行的步骤也不同，但是两者在本发明实施例中起到相同的作用，即，确定终端被盗。在确定之后再执行其他操作，避免因发送被盗指令不及时，导致不法分子有机可乘对终端进行刷机等操作导致被盗终端无法找回的恶劣后果。
另外，本发明实施例中的防盗触发模块1310还能够通过检测到终端的SIM卡是否被更换，确定终端是否被盗。盗窃者在使用被盗终端时，通常会更换SIM卡，否则容易被追溯到，因此，检测SIM卡是否被更换是确定终端是否被盗的一个有效手段。采用本发明实施例能够保证失主没有发现终端被盗的情况下，能够及时发现终端被盗，并及时对被盗终端做出相应处理。
防盗触发模块1310确定终端被盗之后，触发界面显示模块1320。界面显示模块1320受到触发之后，生成无密码锁屏界面并显示。界面显示模块1320显示无密码锁屏界面之后，处理模块1330接收锁屏指令。当处理模块1330接收到锁屏指令时，处理模块1330拒绝屏幕解锁操作，并获取解锁指令发起方的可识别信息。本发明实施例中，终端丢失之后进入锁屏状态。当拾到终端者或者偷盗者企图对终端进行屏幕解锁操作，处理模块1330生成密码输入界面，提示需要输入正确的密码以对屏幕进行解锁。密码输入界面需要使用者输入密码方能解锁，若终端接收到正确的密码，处理模块1330进行屏幕解锁操作。若终端接收到错误的密码，则处理模块1330保持屏幕被锁状态。若一次密码输入有 误，通常会允许再次输入。若多次密码输入(例如3次以上)均不正确，为保证终端安全性，则可能会在一定时间内禁止密码输入以及其他任何操作。
本发明实施例中，该解锁指令发起方的可识别信息可以是通过终端能够获取的、解锁指令发起方的任意可识别信息。优选地，本发明实施例中，可以利用终端的前置摄像头对解锁指令发起方进行拍照，获取照片，还可以记录解锁指令发起方的指纹。本发明实施例中获取到的解锁指令发起方的照片或者指纹为每个人特有的。因此，通过本发明实施例获取到的识别信息能够直接、快速并且有效地寻找到被盗终端的拾到者或者偷盗者，保证被盗终端被找回，进而能够减少终端失窃率并降低偷盗犯罪率。
处理模块1330获取到解锁指令发起方的可识别信息之后，本发明实施例可以通过如图13所示的发送模块1340发送可识别信息至可信任方，还可以保存上述可识别信息等待进一步处理。优选地，本发明实施例中，处理模块1330获取到可识别信息之后，发送模块1340发送该可识别信息至可信任方。其中，该可信任方包括服务器或者被盗终端绑定的亲友号码或者其他可信任方。本发明实施例优选发送模块1340发送可识别信息至可信任方，保证被盗用户能够及时获取到偷盗者的可识别信息，并根据该可识别信息抓获偷盗者，找回被盗终端。
另外，需要说明的是，对于不同的终端以及采用不同操作系统的终端，终端默认锁屏界面的布局和元素存在差异。例如，有的终端默认锁屏界面通过按住屏幕中下方的解锁键向四周滑动解锁。再例如，有的终端默认锁屏界面通过从左向右拖动滑块对屏幕进行解锁。不同终端的锁屏界面还有一些布局细节存在差异，例如获取用户当前设置的桌面壁纸图片资源，或者添加桌面时钟空间的具体方式等，均会因不同终端以及终端中不同的操作系统而存在差异。因此，本发明实施例中生成的无密码屏幕的布局会根据不同的终端以及终端中采用的不同操作系统存在差异。
本发明实施例中，防盗触发模块1310确定终端被盗时，与其耦合的界面显示模块1320生成的无密码屏幕与终端默认锁屏界面可以是相同的，还可以是不同的。优选地，本发明实施例中，无密码屏幕与终端默认锁屏界面是相同的。生成与终端默认锁屏界面不同的无密码屏幕容易被偷盗者识别出终端开启了防盗功能，导致错过获取偷盗者可识别信息的机会。综上，本发明实施例中优选无密码屏幕与终端默认锁屏界面是相同的，可识别度低，并防止偷盗者识别出终端开启了防盗功能，进而增大找回被盗终端的可能性，高效合理保护用户财产安全。
根据上述任意一个优选实施例或多个优选实施例的组合，本发明实施例能够达到如下有益效果：
在本发明实施例中，确定终端被盗时，生成无密码屏幕锁屏界面并显示。偷盗者查看该界面为无密码屏幕锁屏界面时，无法发现终端已开启了防盗功能，会放松警惕直接进行解锁操作。因此，本发明实施例能够延缓解决现有技术中偷盗者通过终端界面显示发现终端已开启防盗功能的时间，避免偷盗者进行拔出终端电池、关闭终端等不利于找回被盗终端的操作。依据本发明实施例能够在接收到解锁指令之后，拒绝解锁，并获取 解锁指令发起方的可识别信息。因此，采用本发明实施例能够解决现有技术中只有解锁失败之后才能进行拍照取证的问题。本发明实施例能够避免因拍照取证的时间间隔较长，导致错过获取偷盗者可识别信息的最佳时机的问题。本发明实施例能够生成无密码界面使偷盗者放松警惕。当偷盗者对终端进行解锁，本发明实施例能够即时获取到该解锁指令发起方(即偷盗者)的可识别信息，无须等待多次解锁失败后才进行拍照取证，缩短拍照取证时间。因此，根据本发明实施例提供的方法能够增大用户找回终端的可能性，更加合理有效保证用户财产安全。
