Description

基于多指纹传感器的指纹模板注册方法、装置及电子设备 技术领域
本申请实施例涉及生物特征技术领域，尤其涉及一种基于多指纹传感器的指纹模板注册方法、装置及电子设备。
背景技术

而上述指纹特征识别功能的实现通常包括两个阶段：指纹模板注册阶段以及指纹特征匹配阶段，在指纹模板注册阶段预先采集指纹特征数据以进行指纹模板的注册，在指纹特征匹配阶段实时采集指纹特征数据并与指纹模板进行比对，从而完成指纹特征的匹配。
由于移动终端使用环境的复杂性，从而导致移动终端使用的安全性较差，比如互联网使用环境中存在诸多不安全因素导致的移动终端使用过程中容易被攻击。

具体实施方式
以下将配合图式及实施例来详细说明本申请的实施方式，藉此对本申请如何应用技术手段来解决技术问题并达成技术功效的实现过程能充分理解并据以实施。
本申请实施例中的电子设备可以为智能手机、平板电脑等移动终端，其中所述指纹传感器可以检测的生物特征包括指纹；在其他实施例中，所述生物特征还可以为心率、血氧浓度等。
本申请实施例中的指纹传感器可以但不限于基于电容效应的传感器，也可以基于光学原理的传感器，还可以为半导体热敏指纹传感器、半导体压感指纹传感器、超声波指纹传感器或者射频RF指纹传感器。
本申请实施例中，指纹传感器可以为在显示屏下(Under display)的结构或者集成到显示屏内(In display)的结构来实现，比如，所述指纹传感器可以采用一个独立功能部件并直接设置在显示屏的显示区域下方。作为一种实现方式，所述指纹传感器可以复用显示屏的部分功能，比如采用OLED(Organic Light-Emitting Diode，简称OLED)显示屏的OLED像素单元作为光源(即OLED光源)等。
与此同时，本申请实施例中，在指纹模板注册阶段，提供指纹模板的注册界面，其中所述注册界面配置有多个注册引导图标，每个注册引导图标分别对应于一个指纹传感器，用于引导手指在其对应的指纹传感器上进行触摸，所述指纹传感器对触摸在其上的手指进行感应并生成指纹特征数据；根据从所述指纹特征数据中提取的指纹特征进行指纹模板的注册，从而可完成多个手指的指纹模板注册，从而提高了使用电子设备的安全性。
具体地，所述注册引导图标分时地或者同时地配置在所述注册界面中，即在引导用户对指纹传感器进行触控时，多个注册引导图标可以同时显示在同一所述注册界面中，也可以在同一所述注册界面中每次只显示一个注册引导图标，通过电子设备的操作系统触发某一个特定的注册引导图标有效，从而启动与有效的注册引导图标对应的指纹传感器对触摸在其上的手指进行感应并生成指纹特征数据，而在启动的多个指纹传感器进行手指感应阶段，所述注册界面优选始终显示在所述电子设备的显示屏上。
具体地，本申请实施例中，每个所述指纹传感器具有唯一性身份标识，比如电子设备上有N个指纹传感器，每个指纹传感器有其唯一的ID号，N个传感器对应的ID号比如分别为：sid1、sid2、……sidN。
进一步地，为了能及时了解指纹模板的注册进度，所述注册界面上还配置有提示框，所述提示框用于提示指纹模板的注册进度。所述提示框的数量为多个，每一个提示框分别对应一个指纹传感器。所述提示框具体可通过示意图、进度条、百分比、字符中的至少一种进行注册进度的提示，详细请参见后续图1-图22示意。
图1-图22分别为本申请实施例一至二十二的注册界面示意图；图1-图22中，以在同一注册界面下同时显示与指纹传感器数量对等的多个注册引导图标为例进行说明，示例性说明了上述多个注册引导图标在同一注册界面中的位置关系，以及示例性在同一注册界面中同时配置有显示注册进度的不同形态的提示框。提示框具体为进度条，同时配置了说明性文字。
如图1-图6所示，若在电子设备上配置有两个指纹传感器，两个注册引导图标可以横向显示，同时，在每个注册引导图标正上方显示指纹传感器的唯一性身份标识，显示注册进度的提示框位于引导注册图标下方或者左右两侧或者围绕引导注册图标。
如图7-18所示，若在电子设备上配置有三个指纹传感器，对应地有三个注册引导图标，三个引导图标可以形成三角形位置关系进行显示，也可以横向显示。唯一性身份标识、显示注册进度的提示框显示方式类似上述图1-图6。
如图19-图22所示，若在电子设备上配置有四个指纹传感器，对应地有四个注册引导图标，四个注册引导图标可以分两排、每排两个进行显示。唯一性身份标识、显示注册进度的提示框的显示方式类似上述图1-图6。
图23为本申请实施例二十三中指纹模板的注册方法的流程示意图；本实施例中，以在智能手机上配置两个作为生物特征传感器的指纹传感器为例进行说明，这两个指纹传感器的ID号分别为sid1、sid2。具体地，为了便于触摸，可以将这两个指纹传感器设置在智能手机的两个侧面，比如ID号为sid1的指纹传感器设置在智能手机的左侧面，用于在右手握持智能手机时，对触摸在其上的食指进行感应，ID号为sid2的指纹传感器设置在智能手机的右侧面，用于在右手握持对触摸在其上的拇指进行感应。需要说明的是，指纹触感器与手指的感应关系也可以进行设置或者调整，比如对于左手握持智能手机的用户来说，ID号为sid1的指纹传感器设置在智能手机的左侧面，用于在左手握持时对触摸在其上的拇指进行感应，ID号为sid2的指纹传感器设置在智能手机的右侧面，用于在左手握持时对触摸在其上的食指进行感应。
但是，需要说明的是，指纹触感器与手指的感应关系也可以不用进行设置，即指纹传感器可以对任一触摸在其上的手指进行感应。
对应地，本实施例中，由于设置有两个指纹传感器，因此，所述注册 界面中显示对应的两个注册引导图标以及两个用于提示注册进度的提示框,注册界面和注册引导图标的设置可参见图1-图6任一所示。
具体地，图23中指纹模板的注册方法包括如下步骤：
S2301、智能手机的操作系统启动之后，检测其配置的指纹传感器的数量；
本实施例中，操作系统可以通过读取硬件配置项文件从而检测到指纹传感器的数量，或者，发送测试信号的方式确定指纹传感器的数量。
S2302、选择启动两个所述指纹传感器对触摸在其上的手指进行感应；
本实施例中，在一种具体应用场景中，在智能手机的显示屏上显示一对话框，在该对话框内显示触发启动上述两个指纹传感器的候选项，用户通过选择所述显示提示框内的候选项从而确定启动对应的指纹传感器。
具体地，在一种应用场景中，也可以按照候选项选择的先后顺序，启动对应的指纹传感器并对触摸在其上的不同手指进行指纹感应。或者，在另外一种应用场景中，为两个指纹传感器设置不同的优先启动级别，按照优先启动级别的高低先后启动对应的指纹传感器并对触摸在其上的不同手指进行感应。或者，若指纹传感器被触摸，即自动启动该被触摸的指纹传感器，具体地，对于两个指纹传感器来说，可以根据指纹传感器被触摸的先后顺序，自动启动对应的指纹传感器并对触摸在其上的不同手指进行感应。
S2303、电子设备的操作系统选择对应的两个所述注册引导图标，并在所述显示屏上显示注册界面以及所述两个注册引导图标；
本实施例中，在一应用场景中，当一个手指在对应的指纹传感器上触摸时比如食指在配置在智能手机左侧面的指纹传感器上触摸，在注册界面中只显示对应的一个注册引导图标，并在该注册界面上显示一个用于提示指纹模板注册进度的提示框；当拇指在配置在智能手机右侧面的指纹传感器上触摸时，在注册界面中再显示对应的另外一个注册引导图标以及提示框；或者，在另外一应用场景中，参考上述图1-图22，在一个注册界面中同时显示两个注册引导图标，在注册界面上同时显示两个用于提示指纹模板注册进度的提示框，当其中一个注册引导图标对应的指纹传感器进行手指感应时，该注册引导图标处于激活状态，以引导用户对对应的指纹传感器上进行触摸，另外还未进行手指感应的指纹传感器对应的注册引导图标 处于未激活状态。
S2304、所述注册引导图标引导手指在对应的指纹传感器上进行触摸；
本实施例中，在一具体应用场景中，在引导用户使用不同的手指在对应的指纹传感器上进行触摸时，比如引导用户在设定的时间间隔内使用拇指、食指分别对设置在智能手机右侧/左侧的指纹传感器分别进行连续触摸。当不同指纹传感器接收到手指的触摸发生在设定的时间间隔范围内，则可认为不同指纹传感器同时接收到了手指的触摸。
S2305、所述指纹传感器对触摸在其上的手指进行感应并生成指纹特征数据；
本实施例中，如前所述，若是电容式指纹传感器，在感应时，可以根据指纹上的谷脊特征形成的电容大小不同来生成指纹特征数据；若是光学式指纹传感器，则可以根据指纹上的谷脊特征形成的指纹图像来生成指纹特征数据。其中，除了谷脊特征外，还可以根据手指纹路上交叉形成的特征来生成指纹特征数据。
本实施例中，在一种应用场景中，具体可以通过同时运行多个注册进程来分别启动多个指纹传感器对触摸在其上的手指同时进行感应并生成指纹特征数据，其中每一个注册进程分别对应一个指纹传感器
需要说明的，在另外一种应用场景中，具体可以通过分时运行多个注册进程来分别启动多个指纹传感器分别对触摸在其上的手指分时进行感应并生成指纹特征数据。
S2306、根据从所述指纹特征数据提取的指纹特征进行指纹模板的注册。
本实施例中，具体从指纹特征数据中提取手指指纹的谷脊特征、手指纹路上交叉形成的特征。
本实施例中，如前所述，由于ID号为sid1的指纹传感器对触摸在其上的食指进行感应，因此，在步骤2306中生成对应食指的指纹模板；由于ID号为sid2的指纹传感器设置在智能手机的右侧面，用于对触摸在其上的拇指进行感应，因此，在步骤S2306中生成对应拇指的指纹模板。
本实施例中，为了区别不同的指纹模板，还可以给每个指纹模板设定对应的唯一性身份标识，比如，ID号为sid1的指纹传感器对食指进行感应，最终得到唯一性身份标识为temp1的指纹模板，ID号为sid2的指纹传感器 对拇指进行感应，最终得到唯一性身份标识为temp2的指纹模板。
进一步地，通过指纹传感器的唯一性身份标识与指纹模板的唯一性身份标识，从而实现指纹传感器与指纹模板之间对应关系的绑定。具体地，该对应关系的绑定具体可以通过指纹传感器和指纹模板的唯一性身份标识之间建立映射关系来实现。
需要说明的是，图23所示实施例的技术方案也可以适用于在智能手机正面的HOME按键处设置一个指纹传感器，在智能手机的背面设置另外一个指纹传感器的情形，HOME按键处设置的指纹传感器对触摸在其上拇指进行感应，智能手机背面设置的指纹传感器对触摸在其上的食指进行感应。
或者，图23所示实施例的技术方案也可以适用于在智能手机显示屏下(Under display)或者在显示屏内(In display)集成一个指纹传感器，同时在智能手机的背面设置另外一个指纹传感器的情形。智能手机显示屏下(Under display)或者在显示屏内(In display)集成的指纹传感器对触摸在其上拇指进行感应，智能手机背面设置的指纹传感器对触摸在其上的食指进行感应。
上述仅以对拇指和食指进行感应做示例性说明，在实际应用时，也可以根据需要，对任意两根手指进行感应从而最终生成不同的指纹模板，而指纹传感器在智能手机上的设置位置并不局限为上述几种情形，指纹传感器在智能手机上的设置位置只要便于用户进行操作即可。
图24为本申请实施例二十四中指纹模板的注册方法的流程示意图；本实施例中，以在智能手机上配置三个及三个以上作为指纹传感器的指纹传感器为例进行说明，这些指纹传感器的ID号分别为sid1、sid2、sid3......。具体地，为了便于触摸，可以将其中的两个指纹传感器分别设置在智能手机的两个侧面，比如ID号为sid1的指纹传感器设置在智能手机的左侧面，用于对触摸在其上的食指进行感应，ID号为sid2的指纹传感器设置在智能手机的右侧面，用于对触摸在其上的拇指进行感应；另外将其中的一个ID号为sid3的指纹传感器设置在智能终端的正面HOME按键处，或者设置在智能终端的背面。
对应地，当设置有三个及三个以上的指纹传感器时，所述注册界面中最多显示与指纹传感器数量对等的多个注册引导图标以及多个用于提示注册进度的提示框。注册界面和注册引导图标的设置可参见图7-图22任一所示。
具体地，图24中指纹模板的注册方法包括如下步骤：
S2401、智能手机的操作系统启动之后，检测其配置的指纹传感器的数量；
本实施例中，操作系统可以通过读取硬件配置项文件从而检测到指纹传感器的数量，或者，发送测试信号的方式确定指纹传感器的数量。
S2402、选择启动的部分所述指纹传感器对触摸在其上的不同手指进行感应；
本实施例中，所述选择启动的所述指纹传感器数量至少为三个，当选择启动的指纹传感器的数量为两个时，类似上述图23。
本实施例中，在一种具体应用场景中，在智能手机的显示屏上显示一对话框，在该对话框内显示触发启动上述多个指纹传感器的候选项，用户通过选择所述显示提示框内的候选项从而确定启动对应的指纹传感器，按照候选项选择的先后顺序，启动对应的指纹传感器并对触摸在其上的不同手指进行指纹感应。或者，在另外一种应用场景中，为多个指纹传感器设置不同的优先启动级别，按照优先启动级别的高低先后启动对应的指纹传感器并对触摸在其上的不同手指进行感应。或者，判断指纹传感器是否被触摸，若被触摸，则自动启动被触摸的指纹传感器，具体地，对于多个指纹传感器来说，可以根据指纹传感器被触摸的先后顺序，自动启动对应的指纹传感器并对触摸在其上的不同手指进行感应。
另外，需要说明的是，在上述这几种启动情形中，启动的指纹传感器可对任意触摸在其上的手指进行感应。但是，在其他一些应用场景中，还可以指定指纹传感器与手指的对应关系，该对应关系可以是一一对应关系，也可以是一对多对应关系，即只有指定的手指触摸对应的指纹传感器，该指纹传感器才会启动。比如设置在智能手机的左侧面且ID号为sid1的指纹传感器，只可对食指或者中指进行感应；设置在智能手机的有侧面且ID号为sid2的指纹传感器，只对拇指进行感应；ID号为sid3的指纹传感器设置在智能终端的正面，由于可以方便任一手指对其触摸，因此，ID号为sid3的指纹传感器可对触摸其的任一手指进行感应。
S2403、电子设备的操作系统选择对应的部分注册引导图标，并在所述显示屏上显示注册界面以及所述部分注册引导图标；
本实施例中，在一应用场景中，当一个手指在对应的指纹传感器上触 摸时比如拇指在配置在智能手机左侧面的指纹传感器上触摸，在注册界面中只显示对应的一个注册引导图标，并在该注册界面上显示一个用于提示指纹模板注册进度的提示框，当另外一个手指在对应的指纹传感器上进行触摸时，在注册界面中再显示对应的另外一个注册引导图标以及提示框；或者，在另外一应用场景中，参考上述图1-图22，在一个注册界面中同时显示多个注册引导图标，并在注册界面上同时显示多个用于提示指纹模板注册进度的提示框，在注册界面中，处于手指感应期间，对应指纹传感器对应的注册引导图标优选始终保持在激活状态。
本实施例中，在注册界面显示的注册引导图标的数量与启动的指纹触感器的数量对等。
当然，在注册界面中也可以显示出对应所有指纹触感器的所有注册引导图标，而其中，只有启动的指纹触感器对应的注册引导图标处于有效状态，即处于引导用户进行手指触摸的状态。
S2404、部分所述注册引导图标引导不同手指在对应的指纹传感器上进行触摸；
本实施例中，在一具体应用场景中，在引导用户使用不同的手指在对应的指纹传感器上进行触摸，比如引导用户在设定的时间间隔内使用拇指、食指分别对设置在智能手机正面/左侧/右侧的指纹传感器分别进行连续触摸。当不同手指对对应指纹传感器上进行触摸的先后时间差位于设定的时间间隔内，则可认为使用不同的手指对对应的指纹传感器同时进行了触摸。
S2405、所述指纹传感器对触摸在其上的手指进行感应并生成指纹特征数据；
本实施例中，如前所述，若是电容式指纹传感器，在感应时，可以根据指纹上的谷脊特征形成的电容大小不同来生成指纹特征数据；若是光学式指纹传感器，则可以根据指纹上的谷脊特征形成的指纹图像来生成指纹特征数据。
S2406、根据从所述指纹特征数据中提取的指纹特征进行指纹模板的注册。
本实施例中，如前所述，由于ID号为sid1指纹传感器设置在智能终端左侧面，可对触摸在其上的食指进行感应，因此，在步骤2306中生成对应食指的指纹模板；由于ID号为sid2的指纹传感器设置在智能终端右侧 面，可对触摸在其上的拇指进行感应，因此，在步骤S2306中生成对应拇指的指纹模板。ID号为sid3的指纹传感器设置在智能终端的正面，可对触摸在其上的任一手指进行感应，比如中指，从而进一步生成对应中指的指纹模板。
类似上述图23，本实施例中，为了区别不同的指纹模板，也可以给每个指纹模板设定对应的模板的编号，比如，ID号为sid1的指纹传感器对食指进行感应，最终得到食指的指纹模板的编号为temp1，ID号为sid2的指纹传感器对拇指进行感应，最终得到拇指的指纹模板的编号为temp2，ID号为sid3的指纹传感器对中指进行感应，最终得到中指的指纹模板的编号为temp3。
需要说明的是，图24所示实施例的技术方案也可以适用于在智能手机显示屏下(Under display)或者在显示屏内(In display)集成一个指纹传感器，形成上述ID号为sid3的指纹传感器，以可对触摸在其上任一手指进行感应。
需要说明的是，在上述图24的基础上，还可以在智能手机背面设置一个指纹传感器，该指纹传感器的ID号为sid4，比如可用于对触摸在其上的食指进行感应。
但是，上述仅以对拇指和食指等手指进行感应做示例性说明，在实际应用时，也可以根据需要，对任意多个手指进行感应从而最终生成不同的指纹模板，而指纹传感器在智能手机上的设置位置并不局限为上述几种情形，指纹传感器在智能手机上的设置位置只要便于用户进行操作即可。
需要说明的是，上述实施例中的手指可以为同一手掌的不同手指，也可以是不同手掌的同一手指或者不同手指。
需要说明的是，上述实施例中，以可实现不同手指同时对不同指纹传感器同时进行触摸，以使得不同指纹传感器对不同手指同时进行感应的方式进行指纹模板的注册。但是，在其他实施例中，也可以不需要进行“同时”的限定，即无需判断不同手指对对应指纹传感器上进行触摸的先后时间差是否位于设定的时间间隔内，而是按照不同手指对对应指纹传感器的先后触摸顺序进行感应。
上述图23或者图24实施例，不同指纹传感器对不同手指进行感应最 终生成不同的指纹模板。但是，需要说明的是，不同指纹传感器对同一手指进行感应并最终生成一个指纹模板。
本申请实施例还提供了一种基于多指纹传感器的指纹模板注册装置，应用于配置有多个指纹传感器的电子设备，其包括指纹模板的注册界面，所述注册界面配置有多个注册引导图标，其中，每个注册引导图标分别对应于一个指纹传感器，用于引导手指在其对应的指纹传感器上进行触摸。
