Description

一种控制终端工作状态的方法和装置 技术领域
本申请涉及但不限于通信技术领域，尤其涉及一种控制终端工作状态的方法和装置。
背景技术
随着指纹识别技术的逐渐成熟，指纹识别功能已开始广泛应用于终端设备，特别是手机、平板等移动终端。由于指纹是独一无二的生物特征属性，因此安全性较高。目前，指纹识别在终端中主要用于解锁，当终端处于锁屏状态时，用户手指触摸一下指纹识别传感器，指纹识别传感器进行一次指纹识别，当指纹识别成功后则解锁进入主界面。因此，当终端处于锁屏状态时，他人无法解锁终端，进而无法获取终端中的信息。然而，当用户对终端解锁后，他人使用该终端时，则可以随意查看终端中的信息，导致终端中的保密信息有泄露的风险，不能保证信息的安全。
虽然可以通过在终端上设置管理员(Administrator)帐户和访客(Guest)账户的方式来限制访客的操作权限，进而保证保密信息的安全。然而，在进行操作权限的切换时，需要退出当前登录的管理员或访客帐户，重新以访客或管理员帐户登录，因此操作极其不便。

本发明的实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例控制终端工作状态的方法，其总的构思为：检测施加在终端人机界面上的预设操作，例如，对人机界面的一个持续的按压操作或触摸操作，即，在人机界面上实施的一个按压操作或触摸操作需持续一个预定的时间值，或者，该预设操作还可以是人体特征的识别操作；对于该预设操作不做具体限制。在检测到人机界面上的这个预设操作后，判定实施该操作的用户为具有特定权限的用户，例如，管理员，机主等，则将终端的工作状态转换到安全工作状态下，即，终端中的任何内容，包括保密信息和非保密信息都可以向该用户展示的一种工作状态，并且，在该状态下，当用户向外发送内容时可以自动为发送内容进行加密，并且对于该终端接收到的加密内容自动解密。反之，当终端未检测到该预设操作时，或者当终端检测到的操作不是上述的预设操作时，终端将会判定实施该操作的用户为不具有特定权限的用户，例如，访客等，则将终端的工作状态转换到非安全工作状态下，即，终端中的保密信息将会隐藏，或加密，该游客将无法看到终端中的保密信息，仅可以浏览非保密信息的一种工作状态，并且在该状态下，当用户向外发送内容时不会对发送内容进行加密，对于接收到的加密内容也不会自动解密。
基于上述构思，本发明实施例的方案为：持续进行生物特征识别获得识别结果；当识别结果为识别成功时，控制工作状态为第一状态；当识别结果为识别失败时，控制工作状态为第二状态。从而，通过持续进行生物特征识别，实现了工作状态的实时控制和快速切换。换句话说，用户可以通过提供或不予提供自己的生物特征信息来控制工作状态，进而实现不同的功能和操作权限。
在本发明实施例中，上述的第一状态即本申请构思中的安全工作状态，第二状态机本申请构思中的非安全工作状态。
其中，生物特征信息可以是指纹信息、眼纹信息、虹膜信息、巩膜信息、面部特征信息、声纹信息等。以指纹信息为例，用户可以通过长按、或以预设频率触摸、或长时间触摸指纹识别传感器作为对终端的工作状态进行快速切换的触发操作信号，即，在保持上述的长按、或以预设频率触摸、或长时间触摸指纹识别传感器时，则将终端的工作状态保持在第一状态，如果用户不保持上述的长按、或以预设频率触摸、或长时间触摸指纹识别传感器时，则将终端的工作状态保持在第二状态，本发明实施例方案通过对预设操作的识别，实现了终端工作状态的灵活转变，从而实现了不同的功能和操作权限。
本发明控制终端工作状态的方法，主要应用于手机、平板等移动终端，也可以应用于笔记本电脑、台式电脑、终端机等计算机终端设备。
以下将通过实施例进行详细说明。
参见图1，提出本发明实施例控制终端工作状态的方法第一实施例，所述方法包括以下步骤S11-S13：
S11、持续进行生物特征识别获得识别结果。判断是否识别成功，当识别成功时，执行步骤S12；当识别失败时，执行步骤S13。
下面通过距离进行说明，在本发明实施例中，例如，对于指纹来说，如果最初设置为当用户长时间触摸人机界面时，则终端进入第一工作状态，那么为了确保用户一直处于预设操作的保持状态，即，确认用户手指一直处于触摸人机界面的状态，则需要终端对该手指的触摸操作进行持续检测。
可选地，终端可以以预设频率持续进行生物特征识别，并持续获得识别结果。进行生物特征识别的频率可以根据需要设定，例如，可以设定每隔0.5秒进行一次生物特征识别，每隔1秒进行一次生物特征识别，每隔5秒进行一次生物特征识别，甚至每隔10秒进行一次生物特征识别，等等。
生物特征信息可以是指纹信息、眼纹信息、虹膜信息、巩膜信息、面部特征信息、声纹信息等。终端可以通过指纹识别传感器进行指纹识别，通过摄像头进行眼纹识别、巩膜识别、虹膜识别或人脸识别，通过语音装置进行声纹识别。
终端进行生物特征识别时，以预设频率持续采集生物特征信息，每采集一次生物特征信息后便进行一次判断和比对，获得本次的识别结果。如图2所示，为终端进行一次生物特征识别的过程，包括以下步骤S111-S114：
S111、采集生物特征信息。判断本次是否采集到生物特征信息，当采集到生物特征信息时，执行步骤S112；当没有采集到生物特征信息时，执行步骤S114。
S112、将本次采集到的生物特征信息与预存的生物特征信息进行比对。判断采集到的生物特征信息与预存的生物特征信息是否匹配，当二者匹配时，执行步骤S113；当二者不匹配时，执行步骤S114。
S113、判定本次识别成功。
当终端采集到的生物特征信息与预存的用户的生物特征信息相匹配，识别成功。
S114、判定本次识别失败。
当终端没有采集到生物特征信息或采集到的生物特征信息与预存的用户的生物特征信息不匹配，识别失败。
当识别成功时，执行步骤S12；当识别失败时，执行步骤S13。
S12、控制工作状态为第一状态。
，当识别成功时，如果当前的工作状态为第一状态，终端则保持当前的工作状态；如果当前的工作状态为第二状态，终端则将工作状态从第二状态切换为第一状态。
可选地，当工作状态为第一状态时，终端对处理的信息进行加密或解密。
可选地，终端对处理的信息进行加密或解密包括：
当该终端接收到加密信息时，自动为所述加密信息解密；当该终端向外发送信息时，自动为需要向外发送的信息加密。
可选地，当工作状态为第一状态时，终端授予操作者第一权限，如管理员权限、最高权限等。
S13、控制工作状态为第二状态。
当识别不成功时，如果当前的工作状态为第二状态，终端则保持当前的工作状态；如果当前的工作状态为第一状态，终端则将工作状态从第一状态切换为第二状态。
可选地，当工作状态为第二状态时，保持所述终端的当前工作状态，终端不对处理的信息进行加密或解密。
可选地，终端不对处理的信息进行加密或解密包括：
当该终端接收到加密信息时，不为所述加密信息解密；当该终端向外发送信息时，不为需要向外发送的信息加密。
可选地，当工作状态为第二状态时，终端授予操作者第二权限，如访客权限等。
本发明实施例控制终端工作状态的方法，通过持续进行生物特征识别，实现了对终端的工作状态的实时控制和快速切换。用户可以通过提供或不予提供自己的生物特征信息来控制工作状态，进而实现不同的功能和操作权限。当终端解锁后被他人使用时，由于终端不能获取用户的生物特征信息而发生了工作状态切换，因此他人不能查看用户的保密信息。从而既保证了信息的安全性，又保证了操作的便捷性。
以下以生物特征信息为指纹信息为例，对本发明实施例的方法进行详细说明。
参见图3，提出本发明实施例中控制终端工作状态的方法第二实施例，所述方法包括步骤S21-S26：
S21、指纹识别传感器以预设频率持续进行指纹识别，并实时向处理模块通知每次指纹识别获得的指纹识别结果。
可选地，可以采用Sensor Hub(或协处理器)技术保持指纹识别传感器处于持续唤醒状态，以降低能耗。
可选地，当指纹识别传感器感应到触摸操作而被触发(或唤醒)时，立即以预设频率持续进行指纹识别，直到没有采集到指纹信息时，才停止本轮指纹识别操作；当再次感应到触摸操作而被触发时，再进行下一轮指纹识别，依此循环进行。此种情形下，每轮指纹识别操作至少进行两次指纹识别，如当用户触摸一下指纹识别传感器后立即放开时，指纹识别传感器就只需进行两次指纹识别后则停止本轮指纹识别操作。通过采取这种轮番指纹识别的方式，使得指纹识别传感器只需间隙性工作而无需持续工作，降低了能耗。
进行指纹识别的频率可以根据需要设定，例如，可以设定每隔0.5秒进行一次指纹识别，每隔1秒进行一次指纹识别，每隔5秒进行一次指纹识别，甚至每隔10秒进行一次指纹识别，等等。
指纹识别传感器进行指纹识别时，以预设频率持续采集指纹信息，每采集一次指纹信息后便进行一次判断和比对，获得本次的指纹识别结果。如图 4所示，为指纹识别传感器进行一次指纹识别的过程，包括以下步骤S211-S214：
S211、采集指纹信息。判断本次是否采集到指纹信息，当采集到指纹信息时，执行步骤S212；当没有采集到指纹信息时，执行步骤S214。
S212、将本次采集到的指纹信息与预存的指纹信息进行比对。判断采集到的指纹信息与预存的指纹信息是否匹配，当二者匹配时，执行步骤S213；当二者不匹配时，执行步骤S214。
S213、判定本次指纹识别成功。
当触摸指纹识别传感器的是用户的手指时，则指纹识别传感器采集到的指纹信息与预存的用户的指纹信息相匹配，指纹识别成功。
S214、判定本次指纹识别失败。
当没有手指触摸指纹识别传感器或触摸指纹识别传感器的不是用户的手指时，指纹识别传感器则不能采集到指纹信息或采集到的指纹信息与预存的用户的指纹信息不匹配，指纹识别失败。
指纹识别传感器每进行一次指纹识别，都实时向处理模块通知本次的指纹识别结果。
可选地，指纹识别传感器可以直接向处理模块发送指纹识别结果。例如，指纹识别传感器可以通过向处理模块发送脉冲信号的方式通知指纹识别结果，不同的指纹识别结果对应不同的脉冲信号。
可选地，指纹识别传感器可以通过修改状态寄存器的状态标识的方式来向处理模块通知指纹识别结果：指纹识别传感器实时根据每次指纹识别获得的指纹识别结果标记状态寄存器的状态标识，处理模块以预设频率读取状态寄存器的状态标识，根据状态标识获取指纹识别结果。处理模块读取状态标识的频率优选与指纹识别传感器进行指纹识别的频率相同，当然也可以不同。
例如，当指纹识别成功时，指纹识别传感器则标记状态寄存器的状态标识为安全状态(如修改状态寄存器的数据为1)；当指纹识别失败时，指纹识别传感器则标记状态寄存器的状态标识为普通状态(如修改状态寄存器的数据为0)。处理模块读取状态寄存器的状态标识，当状态标识为安全状态时，得知指纹识别成功；当状态标识为普通状态时，得知指纹识别失败。
本发明实施例将状态标识定义为安全状态和普通状态，本领域技术人员 可以理解，也可以将状态标识定义为其它名称进行等同替换，例如定义为第一状态和第二状态等，同理均在本发明实施例的保护范围内。
S22、处理模块获取指纹识别结果。判断指纹识别是否成功，当指纹识别成功时，执行步骤S23；当指纹识别失败时，执行步骤S25。
S23、处理模块控制工作状态为安全状态。
本发明实施例将工作状态定义为安全状态和普通状态，即上述的安全工作状态和非安全工作状态。当指纹识别成功时，处理模块确定工作状态为安全状态；如果终端当前的工作状态是安全状态，则保持当前的工作状态；如果终端当前的工作状态是为普通状态，则切换为安全状态。
本领域技术人员可以理解，也可以将工作状态定义为其它名称进行等同替换，例如定义为第一状态和第二状态等，同理均在本发明实施例的保护范围内。
S24、处理模块在安全状态下运行，启用加解密模块对处理的信息进行加密或解密。
在安全状态下，处理模块启动加解密模块。当用户输入信息时，处理模块将用户输入的信息发送给加解密模块进行加密，然后将加密后的信息存储于本地或向外发送；当用户调用信息时，处理模块则将用户调用的信息发送给加解密模块进行解密，然后输出解密后的信息。调用的信息可以是从外部获取的或本地存储的加密信息。调用信息是指打开、播放、查看、读取、写入、修改、删除、启动或解析相关文件或程序。
所述信息的内容包括文字、数字、符号、声音、图像、视频等，如文本文件、视频文件、音频文件、图像文件、实时聊天信息、邮件信息等。
S25、处理模块控制工作状态为普通状态。
当指纹识别失败时，处理模块确定工作状态为普通状态；如果终端当前的工作状态是普通状态，则保持当前的工作状态；如果终端当前的工作状态是安全状态，则切换为普通状态。
S26、处理模块在普通状态下运行，关闭加解密模块，不对处理的信息进行加密或解密。
在普通状态下，处理模块关闭了加解密模块。对于用户输入的信息，处理模块不进行加密操作；同时，对于加密信息，处理模块也不进行解密操作。 也就是说，在普通状态下，用户不能调用加密信息，也不能对输入的信息加密。
本发明实施例控制终端工作状态的方法，通过持续进行指纹识别，实现了工作状态的实时控制和快速切换。用户可以通过长按、或以预设频率触摸、或长时间触摸指纹识别传感器作为对终端的工作状态进行快速切换的触发操作信号，即，在保持上述的长按、或以预设频率触摸、或长时间触摸指纹识别传感器时，则将终端的工作状态保持在第一状态，如果用户不保持上述的长按、或以预设频率触摸、或长时间触摸指纹识别传感器时，则将终端的工作状态保持在第二状态，本发明实施例方案通过对预设操作的识别，实现了终端工作状态的灵活转变，从而实现了不同的功能和操作权限。当终端解锁后被他人使用时，由于用户手指不再触摸指纹识别传感器而发生了状态切换，因此他人不能查看用户的保密信息。从而既保证了信息的安全性，又保证了操作的便捷性。
本发明实施例控制终端工作状态的方法，通过持续进行指纹识别实现了快速增加和取消加密和解密功能。当用户给朋友发送银行卡信息、私密信息、图像信息等保密信息时，希望只有对方能够看到，其他人不能正常打开，则可以通过手指触摸指纹识别传感器快速切换为安全状态，终端则立即对保密信息进行加密后再发送。当接收到加密信息时，则必须通过用户手指触摸指纹识别传感器切换为安全状态后才能正确读取该加密信息。实现了对保密信息的快速加密和解密，提高了信息的安全性和操作的便捷性。
参见图5，提出本发明实施例控制终端工作状态的方法第三实施例，所述方法包括步骤S31-S36：
S31、指纹识别传感器以预设频率持续进行指纹识别，并实时向处理模块通知每次指纹识别获得的指纹识别结果。
S32、处理模块获取指纹识别结果。判断指纹识别是否成功，当指纹识别成功时，执行步骤S33；当指纹识别失败时，执行步骤S35。
本实施例中，步骤S31和S32分别与第一实施例中的步骤S21和S22相同，在此不再赘述。
S33、处理模块控制工作状态为安全状态。
当指纹识别成功时，处理模块确定工作状态为安全状态；如果终端当前 的工作状态是安全状态，则保持当前的工作状态；如果终端当前的工作状态是为普通状态，则切换为安全状态。
S34、处理模块在安全状态下运行，授予操作者第一权限。
本发明实施例中，为终端定义了第一权限和第二权限两种操作权限。其中，第一权限相当于通过管理员帐户登录获得的管理员权限，是最高操作权限，例如可以调用终端中的所有信息；第二权限相当于通过访客帐户登录获得的访客权限，是次一级操作权限，例如只能调用终端中的普通信息。
在安全状态下，处理模块授予当前的操作者第一权限，则当前的操作者可以以管理员身份调用终端中的所有信息，如可以对终端中的所有文件执行读取、修改、删除等操作。
S35、处理模块控制工作状态为普通状态。
当指纹识别失败时，处理模块确定工作状态为普通状态；如果终端当前的工作状态是普通状态，则保持当前的工作状态；如果终端当前的工作状态是为安全状态，则切换为普通状态。
S36、处理模块在普通状态下运行，授予操作者第二权限。
在普通状态下，处理模块授予当前的操作者第二权限，则当前的操作者只能以访客身份调用终端中的普通信息，如只能对终端中的普通文件执行读取、修改、删除等操作，或者只能对普通文件执行读取操作。
本发明实施例控制终端工作状态的方法，通过持续进行指纹识别实现了操作权限的快速转换。当用户触摸指纹识别传感器时，则切换为安全状态，操作者获得最高操作权限，可以操作保密信息；当用户不再触摸指纹识别传感器时，则切换为普通状态，操作者获得次一级操作权限，不能操作保密信息。保证了操作的便捷性和信息的安全性。
前述第二和第三实施例以生物特征信息为指纹信息为例对本发明实施例的方法进行详细了说明，当生物特征信息为眼纹信息、虹膜信息、巩膜信息、面部特征信息、声纹信息等生物唯一识别信息时，其实现方法与指纹信息相类似，在此不再一一列举赘述。
参见图6，提出本发明控制终端工作状态的装置第一实施例，所述装置包括生物特征识别模块10、处理模块20、状态寄存器30和加解密模块40，其中：
生物特征识别模块10：设置为持续进行生物特征识别获得识别结果。
可选地，生物特征识别模块10以预设频率持续采集生物特征信息进行生物特征识别，并实时向处理模块20通知每次生物特征识别获得的识别结果。生物特征识别模块10进行生物特征识别的频率可以根据需要设定。
处理模块20：设置为根据识别结果控制工作状态。当识别结果为识别成功时，控制工作状态为第一状态；当识别结果为识别失败时，控制工作状态为第二状态。
状态寄存器30：设置为存储状态标识。
加解密模块40：设置为对信息进行加密或解密。
其中，生物特征信息可以是指纹信息、眼纹信息、虹膜信息、巩膜信息、面部特征信息、声纹信息等。生物特征识别模块10可以通过指纹识别传感器进行指纹识别，通过摄像头进行眼纹识别、巩膜识别、虹膜识别或人脸识别，通过语音装置进行声纹识别。
可选地，可以采用Sensor Hub(或协处理器)技术保持生物特征识别模块10处于持续唤醒状态，以降低能耗。
可选地，以生物特征信息为指纹信息为例，当生物特征识别模块10通过指纹识别传感器感应到触摸操作而被触发(或唤醒)时，立即以预设频率持续进行指纹识别，直到没有采集到指纹信息时，才停止本轮指纹识别操作；当再次感应到触摸操作而被触发时，再进行下一轮指纹识别，依此循环进行。通过采取这种轮番指纹识别的方式，使得生物特征识别模块10只需间隙性工作而无需持续工作，降低了能耗。
如图5所示，生物特征识别模块10包括采集单元101、存储单元102、判断单元103、比对单元104和通知单元105，其中：
采集单元101：设置为采集指纹信息。当进行生物特征识别时，以预设频率持续采集指纹信息，每采集一次指纹信息，就将采集的数据发送给判断单元103。
存储单元102：设置为存储采集单元101采集的用户的生物特征信息，以作为后续生物特征识别的参考值。
判断单元103：设置为当采集单元101每进行一次生物特征信息采集后，接收采集单元101发送的数据，判断本次是否采集到生物特征信息；当没有 采集到生物特征信息时，判定本次识别失败，并将本次识别结果发送给通知单元105；当采集到生物特征信息时，将本次采集到的生物特征信息发送给比对单元104。
比对单元104：设置为将本次采集到的生物特征信息与存储单元102中存储的生物特征信息进行比对，判断二者是否匹配；当二者匹配时，判定本次识别成功；当二者不匹配时，判定本次识别失败。同时，将本次识别结果发送给通知单元105。
通知单元105：设置为实时向处理模块20通知每次生物特征识别获得的识别结果，也就是说，通知单元105通知的频率与生物特征识别的频率相同，每进行一次生物特征识别，就向处理模块20通知一次识别结果。
本实施例中，通知单元105通过修改状态寄存器30的状态标识的方式来向处理模块20通知识别结果，通知单元105实时根据每次生物特征识别获得的识别结果标记状态寄存器30的状态标识，以使处理模块20通过读取该状态标识来获取识别结果。例如，当识别成功时，通知单元105则标记状态寄存器的状态标识为安全状态(如修改状态寄存器30的数据为1)；当识别失败时，通知单元105则标记状态寄存器30的状态标识为普通状态(如修改状态寄存器30的数据为0)。
如图6所示，处理模块20包括中央处理器201和状态确定单元202，其中：
状态确定单元202：设置为读取状态寄存器30的状态标识，根据状态标识获取识别结果，根据识别结果确定对应的工作状态。状态确定单元202读取状态标识的频率优选与生物特征识别模块10进行生物特征识别的频率相同，当然也可以不同。
例如，状态确定单元202读取状态寄存器30的状态标识，当状态标识为安全状态时，得知识别成功；当状态标识为普通状态时，得知识别失败。
本发明实施例将工作状态定义为第一状态(或安全状态)和第二状态(或普通状态)。当识别成功时，状态确定单元202确定工作状态为第一状态；如果终端当前的工作状态是第一状态，则保持当前的工作状态；如果终端当前的工作状态是第二状态，则切换为第一状态，并启动加解密模块40。
当识别失败时，状态确定单元202确定工作状态为第二状态；如果终端 当前的工作状态是第二状态，则保持当前的工作状态；如果终端当前的工作状态是第一状态，则切换为第二状态，并关闭加解密模块40。
中央处理器201：设置为当工作状态为第一状态时，利用加解密模块40对处理的信息进行加密或解密；当工作状态为第二状态时，不对处理的信息进行加密或解密。
在第一状态下，当用户输入信息时，中央处理器201将用户输入的信息发送给加解密模块40进行加密，然后将加密后的信息存储于本地或向外发送；当用户调用信息时，中央处理器201则将用户调用的信息发送给加解密模块40进行解密，然后输出解密后的信息。调用的信息可以是从外部获取的或本地存储的加密信息。调用信息是指打开、播放、查看、读取、写入、修改、删除、启动或解析相关文件或程序。
在第二状态下，对于用户输入的信息，中央处理器201不进行加密操作；同时，对于加密信息，中央处理器也不进行解密操作。也就是说，在第二状态下，用户不能调用加密信息，也不能对输入的信息加密。
所述信息的内容包括文字、数字、符号、声音、图像、视频等，如文本文件、视频文件、音频文件、图像文件、实时聊天信息、邮件信息等。
本发明实施例所提供的一种控制终端工作状态的装置，通过持续进行生物特征识别，实现了对终端的工作状态的实时控制和快速切换。用户可以通过提供或不予提供自己的生物特征信息来控制工作状态，进而实现不同的功能和操作权限。当终端解锁后被他人使用时，由于终端不能获取用户的生物特征信息而发生了工作状态切换，因此他人不能查看用户的保密信息。从而既保证了信息的安全性，又保证了操作的便捷性。
以生物特征信息为指纹信息为例，用户可以通过长按、或以预设频率触摸、或长时间触摸指纹识别传感器作为对终端的工作状态进行快速切换的触发操作信号，即，在保持上述的长按、或以预设频率触摸、或长时间触摸指纹识别传感器时，则将终端的工作状态保持在第一状态，如果用户不保持上述的长按、或以预设频率触摸、或长时间触摸指纹识别传感器时，则将终端的工作状态保持在第二状态，本发明实施例方案通过对预设操作的识别，实现了终端工作状态的灵活转变，从而实现了不同的功能和操作权限。当终端解锁后被他人使用时，由于用户手指不再触摸指纹识别传感器而发生了状态 切换，因此他人不能查看用户的保密信息。从而既保证了信息的安全性，又保证了操作的便捷性。
本发明实施例控制终端工作状态的装置，可以通过持续进行指纹识别实现快速增加和取消加密和解密功能。当用户给朋友发送银行卡信息、私密信息、图像信息等保密信息时，希望只有对方能够看到，其他人不能正常打开，则可以通过手指触摸指纹识别传感器快速切换为安全状态，终端则立即对保密信息进行加密后再发送。当接收到加密信息时，则必须通过用户手指触摸指纹识别传感器切换为安全状态后才能正确读取该加密信息。实现了对保密信息的快速加密和解密，提高了信息的安全性和操作的便捷性。
参见图9，提出本发明实施例中控制终端工作状态的装置第二实施例，本实施例与第一实施例的区别是省略了状态寄存器30。
本实施例中，生物特征识别模块10向处理模块20通知识别结果的方式是直接向处理模块20发送识别结果：生物特征识别模块10的通知单元105向处理模块20发送携带识别结果的信息，处理模块20的状态确定单元202接收该携带识别结果的信息，获取识别结果。例如，通知单元105可以通过向状态确定单元202发送脉冲信号的方式通知识别结果，不同的识别结果对应不同的脉冲信号。
这种通知方式减少了通知单元105和状态确定单元202的读取操作，可以在一定程度上减少***负载。
参见图10，提出本发明实施例中控制终端工作状态的装置第三实施例，本实施例与第一实施例的区别是省略了加解密模块40。
本实施例中，为终端定义了第一权限和第二权限两种操作权限。其中，第一权限相当于管理员权限，是最高操作权限，例如可以调用终端中的所有信息；第二权限相当于访客权限，是次一级操作权限，例如只能调用终端中的普通信息。
本实施例中，处理模块20设置为：当识别成功时，控制工作状态为第一状态，在第一状态下运行，授予操作者第一权限；当识别失败时，控制工作状态为第二状态，在第二状态下运行，授予操作者第二权限。
在第一状态下，处理模块20的中央处理器201授予当前的操作者第一权限，则当前的操作者可以以管理员身份调用终端中的所有信息，如可以对终 端中的所有文件执行读取、修改、删除等操作。
在第二状态下，处理模块20的中央处理器201授予当前的操作者第二权限，则当前的操作者只能以访客身份调用终端中的普通信息，如只能对终端中的普通文件执行读取、修改、删除等操作，或者只能对普通文件执行读取操作。
本发明实施例控制终端工作状态的装置，通过持续进行生物特征识别实现了操作权限的快速转换。当用户提供生物特征信息(如触摸指纹识别传感器)时，则控制工作状态为第一状态，操作者获得最高操作权限，可以操作保密信息；当用户不再提供生物特征信息(如触摸指纹识别传感器)时，则控制工作状态为第二状态，操作者获得次一级操作权限，不能操作保密信息。保证了操作的便捷性和信息的安全性。
参见图11，提出本发明实施例中控制终端工作状态的装置第四实施例，本实施例与第三实施例的区别是省略了状态寄存器30。
本实施例中，生物特征识别模块10向处理模块20通知识别结果的方式是直接向处理模块20发送识别结果：生物特征识别模块10的通知单元105向处理模块20发送携带识别结果的信息，处理模块20的状态确定单元202接收该携带识别结果的信息，获取识别结果。例如，通知单元105可以通过向状态确定单元202发送脉冲信号的方式通知识别结果，不同的识别结果对应不同的脉冲信号。
这种通知方式减少了通知单元105和状态确定单元202的读取操作，可以在一定程度上减少***负载。
