终端设备和识别指纹的方法 技术领域
本申请涉及电子设备领域，并且更具体地，涉及一种终端设备和识别指纹的方法。
背景技术

但是在手机熄屏需要解锁时，需要在屏内指纹传感器的安放位置显示特定的图标，引导用户进行手指按压，因此增加了手机的功耗。同时，由于屏内指纹技术需要与手机的显示模块和触摸模块配合工作，因此在指纹识别验证的速度不如传统的指纹传感器，因此，用户体验较差。

具体实施方式
下面结合附图，对本申请实施例进行描述。
图1是根据本申请实施例的终端设备100的示意性框图，如图1所示，所述终端设备100可以包括：
第一指纹传感器110、第二指纹传感器120和处理器130；
所述第一指纹传感器110内置于所述终端设备100的屏幕内，所述第二指纹传感器120位于所述终端设备中除所述屏幕以外的其他位置；
所述处理器130，用于根据所述终端设备的状态，控制所述第一指纹传感器和第二指纹传感器的工作模式。
在本申请实施例中，所述第一指纹传感器110内置于所述终端设备的屏幕内，所述第一指纹传感器110的有效检测范围可以与所述终端设备的屏幕大小相同，即整个屏幕的有效显示区域都可以进行指纹验证；或者，所述第一指纹传感器110也可以安装在屏幕内的特定位置，这样进行指纹验证时，需要用户触摸该特定位置，此情况下，进行指纹验证时可以在屏幕上显示用于指示所述第一指纹传感器110安装位置或者有效监测范围的引导图标，以便于引导用户进行指纹按压，本申请实施例对于所述第一指纹传感器110的尺寸不做限定。
作为一种优选的实施例，所述第一指纹传感器110可以采用光学指纹传感器；比如，所述终端设备的屏幕可以为有机发光二极管(Organic Light-Emitting Diode，OLED)屏幕或者其他自发光的显示装置，其具有多个阵列式分布的自发光像素单元，所述光学指纹传感器可以采用所述屏幕的至少部分自发光像素单元作为光源来实现光学式指纹检测；具体地，所述光源发出的光线可以在按压所述屏幕的手指的发生反射，由于指纹的纹峰和纹谷所对应的光路不同，因此通过检测反射光便可以得到手指指纹的纹峰和纹谷所在的位置，即得到指纹图像。可替代地，所述光学指纹传感器本身也可以包括光源，并利用自身光源来实现光学式的指纹检测，在这种情况下所述屏幕可以采用非自发光的显示装置，比如采用背光的液晶显示装置等。作为替代的实施例，所述第一指纹传感器110也可以是设置在所述屏幕下方并位于其显示区域内的电容式指纹传感器或者超声波指纹传感器等。
在本申请实施例中，所述第二指纹传感器120可以为采用其他指纹技术的传感器，例如，电容指纹传感器、超声波指纹传感器，也可以跟第一指纹 传感器120均采用光学指纹传感器等；另外，所述第二指纹传感器120既可以是按压式指纹传感器也可以是滑动式指纹传感器，本申请对此也不做限制。所述第二指纹传感器120可以与所述第一指纹传感器110处于同一平面，具体的，所述第二指纹传感器120可以位于所述终端设备的屏幕的周围，例如，Home键位置，或者，所述第二指纹传感器120也可以与所述第一指纹传感器处于不同平面，例如，所述第二指纹传感器120可以位于所述终端设备的背面，本申请实施例对所述第二指纹传感器的位置不作限定。
在本申请实施例中，所述处理器130可以根据终端设备的状态，确定第一指纹传感器和第二指纹传感器的工作模式，作为示例而非限定，所述终端设备的状态可以包括关机状态、待机状态，工作状态(或者也可以称为解锁状态)。进一步的，待机状态可以包括开机熄屏状态和亮屏未解锁状态。工作状态可以包括亮屏解锁状态但未接收到用户对应用或文件的访问请求(即已解锁但用户未操作应用或文件)，以及接收到用户对应用或文件的访问请求(即已解锁并且用户操作了应用或文件)。所述第一指纹传感器和第二指纹传感器的工作模式可以包括：(1)所述第一指纹传感器处于工作状态，而所述第二指纹传感器处于不工作状态；(2)所述第一指纹传感器处于不工作状态，所述第二指纹传感器处于工作状态；(3)所述第一指纹传感器和所述第二指纹传感器都处于不工作状态；或者，(4)所述第一指纹传感器和所述第二指纹传感器都处于工作状态。
应理解，当指纹传感器处于工作状态时，手指触摸指纹传感器，指纹传感器可以采集指纹信息；当指纹传感器处于不工作状态时，即使手指触摸指纹传感器，指纹传感器也不采集指纹信息，因此，指纹传感器处于不工作状态时，能够降低功耗。
可选地，不工作状态可以包括休眠状态和断电状态，其中，指纹传感器处于休眠状态时，供电电源依然开启，但是指纹传感器未被唤醒，因此，不能采集指纹，断电状态时，指纹传感器的供电电源关闭，因此，断电状态时不能采集指纹。
可选的，在一些实施例中，所述处理器130具体用于：
在所述终端设备处于待机状态的情况下，控制所述第一指纹传感器处于不工作状态，所述第二指纹传感器处于工作状态；或
在所述终端设备处于工作状态，并且接收到用户对应用或文件的访问请 求的情况下，根据所述应用或文件的安全级别，跟预设的安全级别门限的关系，控制所述第一指纹传感器和所述第二指纹传感器的工作模式；或
在所述终端设备处于工作状态，并且未接收到用户对应用或文件的访问请求的情况下，控制所述第一指纹传感器和所述第二指纹传感器都处于不工作状态；或
在所述终端设备处于关机状态的情况下，控制所述第一指纹传感器和所述第二指纹传感器都处于不工作状态。
具体的，所述处理器可以在所述终端设备处于关机状态时，控制所述第一指纹传感器和所述第二指纹传感器都处于不工作状态，因此可以降低终端设备的功耗；或者在所述终端设备处于待机状态，或者说屏幕未解锁时，控制所述第二指纹传感器处于工作状态，所述第一指纹传感器处于不工作状态，由于所述第二指纹传感器比所述第一指纹传感器的功耗低，因此，在待机状态时通过所述第二指纹传感器进行指纹验证比通过所述第一指纹传感器进行指纹验证的功耗低，并且在待机状态时，不必在屏幕显示所述第一指纹传感器的安装位置以便引导用户进行按压，因此，能够进一步降低功耗。
从另一方面来讲，由于采用第一指纹传感器进行验证，需要和显示模块和触摸模块进行配合，指纹验证速度较慢，而通过所述第二指纹传感器进行指纹验证，加快了解锁速度，从而提高了用户体验。退一步讲，屏幕解锁对安全性的要求相对较低，因此，综合考虑安全性和用户体验，在屏幕解锁时，可以采用第二指纹传感器进行指纹验证，从而提升用户体验。
也就是说，在所述终端设备处于关机状态时，控制所述第一指纹传感器和所述第二指纹传感器都处于不工作状态。在所述终端设备处于待机状态时，控制所述第一指纹传感器处于不工作状态，所述第二指纹传感器处于工作状态，可选地，所述第二指纹传感器可以定时从休眠状态唤醒，检测是否有指纹按压。如果有，则唤醒处理器，进行指纹匹配，匹配通过时，解锁终端设备，终端设备进入工作状态。
可选地，在终端设备处于工作状态，并且接收到用户对应用或文件的访问请求的情况下，所述处理器可以根据访问请求访问的文件或应用的安全级别，跟预设的安全级别门限的关系，确定所述第一指纹传感器和所述第二指纹传感器的工作模式。可选地，所述处理器可以在所述文件或用于的安全级别达到预设的安全级别门限的情况下，控制所述第一指纹传感器和所述第二 指纹传感器都处于工作状态，在未达到安全级别门限的情况下，控制只启动第一指纹传感器。也就是说，在终端解锁后，并未接收到用户对应用或文件的访问请求时，所述处理器可以控制第二指纹传感器处于不工作状态，第一指纹传感器也处于不工作状态；或在接收到用户对应用或文件的访问请求的情况下，所述处理器可以根据应用或文件的安全级别确定是开启第一指纹传感器还是开启第一指纹传感器和第二指纹传感器。可选地，当用户想访问安全级别大于预设的安全级别门限的软件或文件，例如，支付类应用，或公司的机密文件等时，所述处理器可以控制所述第一指纹传感器和所述第二指纹传感器都处于工作状态，具体的，所述处理器可以先控制启动第一指纹传感器，再启动所述第二指纹传感器，或者也可以先启动所述第二指纹传感器，再启动所述第一指纹传感器，或者也可以同时启动所述第一指纹传感器和所述第二指纹传感器，由用户确定先在哪个指纹传感器上输入指纹信息。
以下，以所述处理器先启动所述第二指纹传感器为例进行介绍如何进行指纹验证，所述处理器先启动所述第二指纹传感器，具体的，所述处理器可以控制在终端设备的屏幕显示提示信息，所述提示信息用于提示用户在所述第二指纹传感器上输入指纹，当所述第二指纹传感器验证通过的情况下，再控制启动第一指纹传感器，进行手指按压引导，提示用户在所述第一指纹传感器的位置输入指纹，当第一传感器和第二传感器同时验证通过时，验证通过，因此，本申请实施例还可以控制在访问安全级别高于预设的安全级别门限的文件或应用时，控制通过所述第一指纹传感器和所述第二指纹传感器进行验证，在两个指纹传感器都验证通过的情况下，才能确定验证通过，因此，进一步提高了指纹验证的安全性。
可选地，在一些实施例中，还可以预设另一个安全级别门限，所述另一个安全级别门限低于前述的安全级别门限，所述处理器可以在应用或文件的安全级别低于所述另一安全级别门限的情况下，控制所述第二指纹传感器处于工作状态，所述第一指纹传感器处于不工作状态，即通过第二指纹传感器进行指纹验证，因此，本申请实施例可以在用户访问低安全级别门限的应用或文件时，采用第二指纹传感器进行指纹验证，因此，加快解锁速度，提升了用户体验。
可选地，在一些实施例中，所述处理器具体用于：在所述终端设备处于待机状态的情况下，控制所述第一指纹传感器处于不工作状态，所述第二指 纹传感器处于工作状态；或在所述终端设备处于工作状态，并且接收到用户对应用或文件的访问请求的情况下，控制所述第一指纹传感器处于工作状态，所述第二指纹传感器处于不工作状态；或在所述终端设备处于工作状态，并且未接收到用户对应用或文件的访问请求的情况下，控制所述第一指纹传感器和所述第二指纹传感器都处于不工作状态；或在所述终端设备处于关机状态的情况下，控制所述第一指纹传感器和所述第二指纹传感器都处于不工作状态。
跟前述实施例不同的是，所述处理器在接收到用户对应用或文件的访问请求的情况下，可以不进行应用或文件的安全级别的判断，直接设置所述第一指纹传感器处于工作状态，所述第二指纹传感器处于不工作状态，即通过所述第一指纹传感器进行指纹验证。
可选的，在一些实施例中，所述处理器还用于：
根据所述第一指纹传感器和所述第二指纹传感器的工作模式，进行指纹识别。
具体的，在所述第一指纹传感器处于不工作状态，所述第二指纹传感器处于工作状态的情况下，通过所述第二指纹传感器获取用户的指纹信息，对所述指纹信息进行指纹识别；或
在所述第一指纹传感器处于工作状态，所述第二指纹传感器处于不工作状态的情况下，通过所述第一指纹传感器获取用户的指纹信息，对所述指纹信息进行指纹识别；或
在所述第一指纹传感器和所述第二指纹传感器都处于工作状态时，通过所述第一指纹传感器和所述第二指纹传感器获取用户的指纹信息，对所述指纹信息进行指纹识别。
可选地，在本申请实施例中，所述处理器130所执行的功能可以直接体现为由硬件处理器执行完成，或者用处理器中的硬件及软件模块组合执行完成，或者也可以由软件模块来执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。所述存储介质可以位于所述终端设备的存储器中，所述处理器130可以通过运行存储在存储器中的软件程序或模块，从而执行所述终端设备中的各种功能应用或数据处理，存储器可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需 的应用程序(比如声音播放功能、图象播放功能等)等；存储数据区可存储根据终端设备100的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
可选地，所述终端设备可以为手机、平板电脑等，本申请实施例对此不作限定。
可选地，在本申请实施例中，所述第一指纹传感器比所述第二指纹传感器的安全性高，所述第二指纹传感器比所述第一指纹传感器的功耗低。
因此，本申请实施的终端设备，可以包括两个指纹传感器，即第一指纹传感器和第二指纹传感器，其中，第一指纹传感器的安全性比所述第二指纹传感器的安全性高，第二指纹传感器的功耗比第一指纹传感器的功耗低，从而在终端设备处于待机状态时，使用功耗较小的第二指纹传感器进行解锁，加快了解锁速度，提升了用户体验，在手机支付等安全性要求比较高的场合，使用安全性较高的第一指纹传感器，或第一指纹传感器和第二指纹传感器进行指纹验证，提高了指纹验证的安全性，因此，能够兼顾指纹验证的安全性和用户体验。
作为另一种优选的实施例，考虑到不同用户的指纹可能具有不同的特性，所述终端设备的第一指纹传感器110和第二指纹传感器120可以分别采用不同类型的指纹传感器，比如所述第一指纹传感器110采用光学式指纹传感器，而所述第二指纹传感器120采用电容式指纹传感器。采用上述配置方式的其中一个优点在于，有些用户的指纹特性导致其更容易被电容式指纹传感器识别，而有些用户的指纹特性导致其更容易被光学式指纹传感器识别，因此所述终端设备可以适用于不同使用者的指纹特性，从而有效提高用户体验。采用上述配置方式的另一个优点在于，不同类型的指纹传感器各有优势，比如光学式指纹传感器在湿手指或手指带有灰尘时仍可以较为有效准确地进行指纹识别，而且还可以实现活体检测；而电容式指纹传感器的指纹识别效率更高，指纹解锁时间更短。因此，当用户在不同应用场景下可以选择所述第一指纹传感器110和所述第二指纹传感器120其中之一来进行指纹识别，从而满足不同场景的应用需求。
上文结合图1，详细描述了本申请的装置实施例，下文结合图2至图5，详细描述本申请的方法实施例，应理解，方法实施例与装置实施例相互对应， 类似的描述可以参照装置实施例。

在所述应用或文件的安全级别未达到预设的安全级别门限的情况下，控制所述第一指纹传感器处于工作状态，所述第二指纹传感器处于不工作状态。
可选的，在一些实施例中，所述根据终端设备的状态，控制所述第一指纹传感器和第二指纹传感器的工作模式，包括：

可选的，在一些实施例中，所述第一指纹传感器比所述第二指纹传感器的安全性高。
可选的，在一些实施例中，所述第二指纹传感器与所述第一指纹传感器处于同一平面或不同平面。
应理解，该方法200可以由终端设备中的处理器执行，所述处理器可以为图1所示的处理器130，可选地，所述终端设备还可以包括存储器，所述存储器可以用于存储程序、指令或代码，所述处理器可以执行存储在所述存储器中的程序、指令或代码，使得所述终端设备可以执行方法200中的相应内容。
具体的，本申请实施例所公开的方法的内容可以直接体现为硬件处理器执行完成，或者用处理器中的硬件及软件模块组合，或者用软件模块执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。所述存储介质位于终端设备的存储器中，终端设备中的处理器可以读取存储器中的信息，完成上述方法的内容。为避免重复，这里不再详细描述。
以下，以所述终端设备为手机为例，详细介绍本申请实施例的识别指纹的方法，但不应对本申请实施例构成限定。
应理解，为便于描述，以手机中包括的所述第一指纹传感器位于屏幕的特定位置，所述第二指纹传感器位于手机的背部为例进行介绍，但不应对本申请实施例构成任何限定，在本申请实施例中，所述第一指纹传感器和所述第二指纹传感器的位置可以参考前述实施例，为了简洁，这里不再赘述。
图3所示为在手机在待机状态时的示意图，此情况下，所述第一指纹传感器处于不工作状态，所述第二指纹传感器处于工作状态，因此，如图4所示，可以通过触摸第二指纹传感器进行熄屏唤醒或亮屏解锁，因此，避免了采用第二指纹传感器进行指纹验证，在待机状态时，仍然需要在屏幕上显示所述第一指纹传感器的安装位置，以便于引导用户进行指纹按压，导致功耗较大的问题。
可选地，在手机解锁后，在用户需要操作手机支付等安全性要求较高的软件时，所述第一指纹传感器处于工作状态，所述第二指纹传感器处于不工作状态，此时，可以通过第一指纹传感器进行指纹验证，由于第一指纹传感器的尺寸相对第二指纹传感器的尺寸较大，相当于增加了密码的长度，因此，指纹识别的安全性较高。具体的，如图5所示，用户操作支付软件时，所述支付软件可以通过访问手机中的处理器，例如，处理器中的软件中间件，控制在所述手机的屏幕上显示引导位置，所述引导位置为所述第一指纹传感器的安装位置，用户按压所述引导位置，从而所述第一指纹传感器可以采集用户的指纹信息，采集完成后，可以对指纹进行验证，验证通过后，可以准许支付。
应理解，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后 关联对象是一种“或”的关系。
