具体实施方式
本申请实施例涉及的基于指纹识别的开机方法适用于终端设备中，如计算机、平板电脑(Portable Android Device；PAD)等，当然，也可以适用于其他具有开机按键以及可以利用指纹数据进行登录的设备中。
本申请实施例涉及的基于指纹识别的开机方法，主要针对的是在使用指纹作为终端设备开机的验证方式时，如何在提高用户体验的同时，延长电池的续航时间。在对终端设备进行开机的过程中，采用指纹进行认证时，可以包括两种实现方式：一种是电源按键与指纹传感器分离方案，即用户需要操作电源按键，登陆时再次录入指纹，这样，用户需要执行两次操作，从而导致用户的体验不好。另一种实现方式为，系统在关机状态需要对指纹传感器持续供电源，在用户录入指纹后对非传感器部分上电，如指纹认证成功则执行登陆操作。但是这种方式需要在关机状态下对指纹传感器供电，从而降低了电池的续航时间。
因此，本申请实施例提供的基于指纹识别的开机方法和设备，旨在解决开机与指纹认证操作多次的问题，以及在采用指纹方式进行认证开机时，电池的续航时间较短的技术问题。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请基于指纹识别的开机方法实施例一的流程示意图。本申请实施例提供了一种基于指纹识别的开机方法，该方法可以由任意执行基于指纹识别的开机方法的装置来执行，该装置可以通过软件和/或硬件实现。本实施例中，该装置可以集成在终端设备中。如图2所示，本实施例的方法可以包括：
步骤201、在检测到开机信号时，采集指纹数据。
在本实施例中，当电源按键被用户按压时，终端设备将会检测到开机信号，此时，终端设备中的电源控制器将控制DC/DC上电，以输出各路电源，其中包括指纹传感器电源，在用户按压电源按键的过程中，指纹传感器完成上电，并在用户的手指离开电源按键之前开始采集指纹数据。
步骤202、将指纹数据与预先存储的预设指纹数据进行匹配。
在本实施例中，终端设备中将预先存储有一个或者多个允许登录该终端设备的用户的指纹数据，终端设备在采集到指纹数据之后，会将采集到的指纹数据与预先存储的预设指纹数据进行匹配。
在一种可能的实施方式中，预设指纹数据可以是用户之前录入的指纹数据，也可以是从服务器同步过来的指纹数据，可以是指纹的图像，也可以是根据指纹图像提取的特征值，以上数据可以加密或不加密存储。
步骤203、若匹配成功，则登陆终端设备。
在本实施例中，终端设备将采集到的指纹数据与预先存储的预设指纹数据进行匹配之后，若匹配成功，则登陆终端设备。
本申请实施例提供的基于指纹识别的开机方法，在检测到开机信号时，将采集指纹数 据，将指纹数据与预先存储的预设指纹数据进行匹配，若匹配成功，则登陆终端设备。由于终端设备在检测到开机信号时，便采集指纹数据，这样可以在完成开机的过程中录入指纹数据，由此可以避免开机与指纹认证操作需要分别进行两次操作，或者在关机状态下需要持续为指纹传感器供电的现象，从而不仅可以提高终端设备登陆的效率，而且可以提高终端设备电池的续航时间。
可选地，若指纹数据与预先存储的预设指纹数据匹配失败，则输出提示信息，该提示信息包括文字信息、声音信息或灯光信息中的至少一种。提示信息可以提示用户移动手指或重新按压电源按键。
具体地，若采集到的指纹数据与预先存储的预设指纹数据不相符，即匹配失败时，将输出提示信息，以提示用户输入的指纹有误。图3为输出提示信息的界面示意图，如图3所示，若匹配失败，将在终端设备的界面上显示“指纹输入错误”的信息来提醒用户。在实际应用中，除了文字信息之外，该提示信息还可以包括声音信息或灯光信息等，例如终端设备可以通过语音播报的方式提醒用户，或者通过声音信息提醒用户，还可以通过灯光闪烁的方式提醒用户等。另外，终端设备可以仅采用上述提示信息中的一种方式来提醒用户，也可以采用上述提示信息中的两种或两种以上的组合方式来提醒用户，对于提示信息的具体方式，本实施例在此不作限制。
图4为本申请实施例提供的终端设备实施例一的结构示意图。如图4所示，该终端设备包括：电源按键、指纹采集模块、指纹识别模块和电源控制模块，所述指纹采集模块设置于所述电源按键上，包括：
所述电源控制模块，用于在检测到所述电源按键被按压时，控制电源输出对指纹采集模块供电；
所述指纹采集模块，用于采集指纹数据，并向所述指纹识别模块发送所述指纹数据；
所述指纹识别模块，用于将所述指纹数据与预先存储的预设指纹数据进行匹配；
所述登陆模块，用于在所述指纹识别模块匹配成功时，登陆所述终端设备。
在本实施例中，该系统包括指纹及按键模组、指纹识别模块、存储器、EC、电源控制模块、DC/DC、电池、AC/DC适配器、平台电源，其中，指纹及按键模组用于提供开关机功能以及指纹录入，电池为为单板提供电源的装置，AC/DC适配器为为电池充电的装置，DC/DC为单板电源转换器，用于提供单板芯片电源，电源控制器用于控制DC/DC输出各路电源，指纹识别模块用于对采集的指纹进行识别，EC为单板外设及IO控制器件，存储器为处理器外挂内存颗粒，平台电源为指纹采集模块以外电源，例如CPU电源，EC电源等。
指纹采集模块设置在电源按键上，组成指纹及按键模组，当用户按压电源按键后，电源控制模块将检测到开机信号，此时，终端设备中的电源控制模块将控制DC/DC上电，以输出各路电源，其中包括指纹采集模块电源，在用户按压电源按键的过程中，指纹采集模块完成上电，并在用户的手指离开电源按键之前开始采集指纹数据。其中，电源控制模块可以为电源控制器，指纹采集模块可以为指纹传感器，指纹识别模块可以是终端设备的中央处理器(Central Processing Unit，CPU)，也可以是微控制单元(Microcontroller Unit，MCU)。
当指纹识别模块为CPU时，指纹采集模块在采集到指纹数据之后，将指纹数据进行 缓存，当CPU上电后，CPU会向指纹采集模块发送通知消息，指纹采集模块在接收到该通知消息之后，会将采集到的指纹数据发送给指纹识别模块。其中，指纹采集模块可以只采集一个指纹数据，并将采集的指纹数据进行缓存。另外，为了提高指纹的清晰度，提升指纹数据的识别效率，指纹采集模块也可以采集多个指纹数据，并通过比对，从这多个指纹数据中挑选出一个最优的指纹数据进行缓存。
可选地，指纹采集模块还可以通过判断自身与CPU是否同步上电，以确定是否缓存采集到的指纹数据，在实际应用中，CPU可以通过GPIO引脚来输出高电平或者低电平至指纹采集模块，指纹采集模块将根据输入的电平高低来判断CPU是否已经完成初始化，若指纹采集模块判断出CPU已经完成初始化，但指纹数据还未采集完成，则指纹采集模块可以不用缓存采集到的指纹数据，而直接将后续采集到的指纹数据发送给指纹识别模块，由此可以提高指纹数据识别的效率。
指纹识别模块在接收到指纹采集模块发送的指纹数据之后，会将该指纹数据与预先存储的预设指纹数据进行匹配，若匹配成功，则登录终端设备。其中，指纹识别模块中可以预先存储有一个用户的指纹数据，也可以预先存储有多个允许登陆终端设备的用户的指纹数据。
在一种可能的实施方式中，以windows系统为例，指纹识别模块将匹配成功的消息发送给登陆模块，登陆模块即可以登陆系统。登陆模块可以为windows系统中进行身份识别的软件模块，也可以为向windows系统发送登陆指令的软件和/或硬件。
可替代的，指纹识别模块也可以在验证通过后，将预存的指纹数据发送给登陆模块。这一实施方式没有改变系统自身的指纹登陆认证方式，可以适配于多种现有的系统。
在一种可能的实施方式中，指纹识别模块可以在完成指纹识别之后即将匹配成功的消息或者预存的指纹数据发送给登陆模块。可替代的，在指纹匹配成功和系统登陆之间可能有时间差，即指纹匹配成功了，系统尚未进入登陆阶段，指纹识别模块也可以将匹配成功的结果缓存起来，在系统进入登陆阶段时再将匹配成功的消息或者预设的指纹数据发送给登陆模块。
当指纹识别模块为MCU时，MCU中将预先存储有一个或多个指纹数据，且该MCU将专门用于进行指纹数据的匹配。另外，指纹采集模块也可以通过判断自身与MCU是否同步上电，以确定是否缓存采集到的指纹数据，在实际应用中，MCU可用IO信号高低电平输出至指纹采集模块，指纹采集模块将根据输入的电平高低来判断MCU是否完成上电，若指纹采集模块与MCU没有同步上电，即指纹采集模块已经上电，而MCU还未上电时，指纹采集模块会将采集到的指纹数据进行缓存，当MCU上电之后，指纹采集模块将缓存的指纹数据发送给MCU，以使MCU进行指纹数据的匹配。若指纹采集模块判断出其与MCU同步上电，即判断出MCU已经完成上电，但指纹数据还未采集完成，则指纹采集模块无需缓存采集的指纹数据，而是直接将后续采集到的指纹数据发送给MCU，由此可以提高指纹识别的效率。另外，若指纹识别模块为MCU，由于MCU将专门用于进行指纹数据的匹配，因此，若采集的指纹数据与预先存储在MCU中的预设指纹数据匹配失败时，在终端设备还未进入登录界面时，终端设备便可以向用户发出提示信息，以提醒用户指纹输入错误，由此可以提高用户的体验。
当指纹识别模块为MCU时，MCU在将指纹采集模块采集到的指纹数据与预先存储 的预设指纹数据进行匹配之后，可以直接将匹配后的结果发送给CPU，以使CPU根据匹配结果控制是否登陆终端设备，其中，若匹配成功，则登陆终端设备，若匹配失败，则将输出提示信息，以提醒用户指纹输入错误。由于MCU进行指纹数据的匹配之后，直接将匹配后的结果发送给CPU，由此可以提高CPU的处理效率。另外，MCU进行指纹数据的匹配之后，若匹配成功，也可以直接将匹配成功之后的指纹数据发送给CPU，CPU将保存该指纹数据，并控制登陆终端设备，若CPU未接收到MCU发送的指纹数据，则说明匹配失败，CPU将输出提示信息，以提醒用户指纹数据输入错误。
可选地，所述终端设备还包括触点，电源按键和该触点联动，在触点接通时，电源按键的行程小于或等于电源按键的最大行程。
具体地，图5为电源按键的结构示意图一，如图5所示，由于电源按键11和触点12联动，当用户按压电源按键11时，触点12也会相应运动，以使电源控制模块为终端设备的其他部件供电。当用户按压电源按键11，在触点12接通，即电路处于闭合时，电源按键11的行程若等于电源按键的最大行程，此时，由于电源按键被按压到最大行程时，触点才接通，也即指纹采集模块才能上电，则用户在按压电源按键之后，手指需要在电源按键处停留预设时间，以保证指纹数据采集的完整性和准确性，其中，预设时间可以根据经验或者实际情况进行设置，例如可以设置为1s、1.5s等，对于预设时间的具体取值，本实施例在此不作限制。
终端设备还可以输出提示信息，包括文字信息、声音信息或灯光信息等，提示用户按压一段时间。例如屏幕上显示进度条，指示灯颜色从红色变成绿色等，使得用户能够知道指纹识别是否成功。以windows系统为例，从开机到显示登陆界面需要几秒到几十秒时间，如果用户按压电源按键时指纹识别没有成功，等到屏幕显示登陆界面时才发现，就不得不再进行一次指纹识别，会造成二次操作的不便。还因为指纹采集模块设置在电源按键上，还有可能在再次进行指纹识别时无意中按压到电源按键使得终端设备关机，带来误操作。
图6为电源按键的结构示意图二，如图6所示，在上述情况的基础上，当用户按压电源按键，在触点接通，即电路处于闭合时，电源按键的行程小于电源按键的最大行程，此时，由于电源按键还没有被按压到最大行程时，触点就已经接通，也即指纹采集模块已经上电，则用户在按压电源按键时，用户只需要将电源按键按压到最大行程，指纹采集模块就能够采集到指纹数据，由此可以提高指纹数据采集的效率。另外，为了提高指纹数据采集的完整性和准确性，用户在按压电源按键时，手指也可以在电源按键处停留预设时间，终端设备也可以按上述列举的方式对指纹识别的结果进行提示。
本申请实施例提供的终端设备，包括电源按键、指纹采集模块、指纹识别模块、电源控制模块和登陆模块，指纹采集模块设置于电源按键上，其中，电源控制模块，用于在检测到开机信号时，控制电源输出对指纹采集模块供电；指纹采集模块，用于采集指纹数据，并向指纹识别模块发送指纹数据；指纹识别模块，用于将指纹数据与预先存储的预设指纹数据进行匹配；登陆模块，用于在指纹识别模块匹配成功时，登陆终端设备。由于将指纹采集模块设置于电源按键上，当用户按压电源按键，在指纹采集模块供电后，指纹采集模块便开始采集指纹数据，这样可以在完成开机的过程中录入指纹数据，由此可以避免开机与指纹认证操作需要进行多次，且在关机状态下需要持续为指纹传感器供电的现象，从而不仅可以提高终端设备登陆的效率，而且可以提高终端设备电池的续航时间。
