下面将结合附图对本发明实施例作进一步地详细描述。
请参阅图1及图2，本发明较佳实施方式的指纹解锁系统10可用于电子装置100，并用于管理电子装置100的存取权限。电子装置100在特定操作后或者闲置一定时间后进入锁定状态，禁止用户存取电子装置100的数据，即无法读取电子装置100的数据也无法给电子装置100写入数据。指纹解锁系统10可以给电子装置100解锁，即允许用户通过特定的指纹操作后解锁电子装置100并在解锁后存取电子装置100的数据。
另外，指纹解锁系统10的应用并不限于本实施方式，在其他实施方式中，可以应用于其他产品或场合，例如门禁系统。
指纹解锁系统10包括指纹检测单元12、数据库14及解锁模块16。指纹检测单元12用于采样指纹。数据库14用于存储解锁密码，解锁密码包括预存指纹及预存指纹在指纹检测单元12的预存位置。解锁模块16与指纹检测单元12及数据库14连接，用于判断采样指纹是否为预存指纹。解锁模块16还用于在采样指纹为预存指纹时判断采样指纹在指纹检测单元12上的位置与预存指纹在指纹检测单元12的预存位置是否一致并在一致时解锁电子装置100。
电子装置100可以是手机等便携式智能终端。本实施方式中，电子装置100为手机，并基本呈矩形，具有正表面(即正常使用时面向用户的表面)及右侧面(即正常使用时用户右手持机手指覆盖的侧面)及顶侧面(即正常使用时用户右手持机食指容易覆盖的侧面)。电子装置100包括位于正表面的显示屏幕101。显示屏幕101用于显示各种信息。
指纹检测单元12可以是采用光学技术或超声波技术的器件或者为电容触摸屏幕。本实施方式中指纹检测单元12采用电容触摸屏幕。
本实施方式中，指纹检测单元12包括设置在电子装置100的右侧面第一子单元121及设置在电子装置100的顶侧面的第二子单元122，如此，用户持机时即可分别用多个手指的指纹在电子装置100的不同表面进行解锁操作。方便使用。
也即是说，本实施方式中，指纹检测单元12与显示屏幕101为独立的器件。在解锁过程中，无需启动显示屏幕101，或者可设置在解锁后才能启动显示屏幕101。如此，一方面 可以节省电能，另一方面，可以保护显示屏幕101的屏保信息，提高隐私保护水平。
当然，指纹检测单元12在电子装置100上的设置并不限于本实施方式，可以根据需求设置在电子装置100的其他位置，例如底面(即正常使用时背向用户的表面)。另外，指纹检测单元12也可以是单一器件，而不限于本实施方式，即不分为第一子单元122及第二子单元124。在这种情况下，指纹检测单元12仍然可以单独于显示屏幕101设置。
指纹检测单元12包括有多个键区123，每个键区123限定一个位置。也即是说，指纹落入一个键区123内的任何位置都认定为同一个位置。各个键区123的形状及大小可以设置相同也可以不同。例如，本实施方式中，指纹检测单元12包括位于右侧面的六个键区123及顶侧面的三个键区123。右侧面的六个键区123均为矩形，且大小相同，而顶侧面的键区123也为矩形，且大小相同。
可以理解，键区123的数目、形状及大小设置并不限于本实施方式，可以视需求而定。例如，在其他实施方式中，键区123可以是圆形或椭圆形等。
键区123之间可以有物理的分割线124。在其他实施方式中，指纹检测单元12可以有显示功能，并显示分割线124，也即是说分割线124为虚拟线。例如，指纹解锁系统10包括有与指纹检测单元12连接的显示控制模块18，用于控制指纹检测单元12显示分割线124。
另外，指纹检测单元12还可以在每个键区123内显示标识125，方便用户在解锁时识别位置，例如，在本实施方式中的九个键区123分别显示数字“1-9”以模仿密码键盘。也即是说，显示控制模块18还用于控制指纹检测单元12显示标识125。当然，标识125并不限于数字“1-9”，而可以是其他可以标识键区123的符号(例如汉字或图案等)。
当然，分割线124及标识125均不限于本实施方式，在其他实施方式中可以略去。
数据库14可以是通过无线通信方式连接的云端数据库，也可以是电子装置100的存储装置(例如是电子装置100的内存或者存储卡等)，并包括一个或者多个解锁密码。数据库14可以在设定模式时进行编辑。本实施方式中，指纹解锁系统10包括有与指纹检测单元12及数据库14连接的设定模块19，用于启动后记录用户在指纹检测单元12的操作并存储在数据库14上。也即是说将预存指纹及预存指纹在指纹检测单元的预存位置存储在数据库14上作为解锁密码。设定模块19可以通过特定的操作(例如按下电子装置100的特定按键或者按键组合)启动。
解锁模块16可以是在电子装置100的处理器运行的软件模组或者独立的硬件模组，并在运行或者启动时具有解锁模块16的功能。
请参阅图3，本发明另一个较佳实施方式的指纹解锁系统10中，指纹检测单元12a与 显示屏幕101可以集成一体，形成指纹采样屏幕，例如显示屏幕101采用电容触摸屏幕，通过显示屏幕101采样指纹。另外，在其他实施方式中，指纹检测单元12a还可以包括多个子单元，其中部分子单元独立于显示屏幕101设置，而部分子单元集成在显示屏幕101上。例如，在上面的实施方式中，除了第一子单元122及第二子单元124外，显示屏幕101也作为指纹检测单元12的子单元(例如为第三子单元)。
在本实施方式中，指纹检测单元12a同样可以设置有键区123a，并有分割线124a及标识125a(例如数字“1-9”)等。
在本实施方式中，指纹检测单元12a用于采样指纹，还可以具有触控显示屏的功能。数据库14用于存储解锁密码，解锁密码包括预存指纹、预存指纹在指纹检测单元12a的预存位置、预存指纹的预存出现次序及预存指纹的预存位置变化。解锁模块16与指纹检测单元12a及数据库14连接，用于判断采样指纹是否为预存指纹。解锁模块16还用于在采样指纹为预存指纹时判断采样指纹在指纹检测单元12a上的位置、出现次序及位置变化是否与预存指纹在指纹检测单元12a的预存位置、预存指纹的预存出现次序及预存指纹的预存位置变化一致并在一致时解锁电子装置100。
本发明较佳实施方式的指纹解锁方法可以由指纹解锁系统10执行，并包括以下步骤：
S1：采样指纹；
S2：判断采样指纹是否为预存指纹；
S3：若采样指纹为预存指纹则判断采样指纹在指纹检测单元12上的位置与预存指纹在指纹检测单元12的预存位置是否一致；及
S4：若一致，解锁电子装置100。
本实施方式中，指纹解锁方法还包括以下步骤：
S0：设置并存储解锁密码，解锁密码包括预存指纹、预存指纹在指纹检测单元12的预存位置。
其中，步骤S0可以由设定模块19、指纹检测单元12及数据库14共同实现。步骤S1可以由指纹检测单元12实现，步骤S2-S4可以由解锁模块16实现。
本实施方式中，以指纹检测单元12为例(即以电容触摸屏幕为例)，步骤S0包括：
S01：开启设定模式；
S02：采样施加到指纹检测单元12及识别对应的位置；及
S03：保存指纹为预存指纹及对应的位置为所述预存指纹的预存位置。
在步骤S01中，电子装置100可以具有特定的按键或者按键组合，可以在按下后启动设定模块18并关闭解锁模块16，如此，只有设定模块18可以读取用户在指纹检测单元12 上的操作信息。另外，还可以设定，设定模式只有在解锁后才可以进行，防止安全漏洞。
步骤S02包括采样同一指纹施加到同一位置(例如键区123)、多个不同的指纹施加到多个不同的位置(例如不同键区123)、同一指纹施加到多个不同的位置(例如不同键区123)及多个不同的指纹施加到多个不同的位置。例如用户可以将中指放置到同一键区123(例如“3”)，如此，指纹检测单元12可以采样中指指纹并记录所在的键区123(例如“3”)，用户也可以将小指、无名指及中指放置到多个不同的键区123(例如“3”、“6”及“9”)，如此，指纹检测单元12可以采样这些指纹并记录所在的键区123(例如“3”、“6”及“9”)。用户也可以将中指放置到多个不同的键区123(例如“3”、“6”及“9”)，如此，指纹检测单元12可以采样中指指纹并记录所在的键区123(例如“3”、“6”及“9”)。
解锁密码设定后可以通过按下电子装置100的特定按键或者按键组合关闭设定模式，也即是设定模块18关闭，同时解锁模块16启动接收用户输入，并实行解锁动作。
在步骤S1中，用户在指纹检测单元12操作后，指纹检测单元12可以采样指纹。
在步骤S2中，解锁模块16先比较采样指纹与预存指纹，若采样指纹可在预存指纹找到配对，则进行步骤S4，若不存在配对，则提示密码错误，解锁失败。
在步骤S3中，解锁模块16实际上验证用户在指纹检测单元12上的操作是否与设定解锁密码时用户在指纹检测单元12上的操作一样。这一步骤实际上在指纹识别解锁的基础上加上密码解锁，密码即是指纹的位置，只有这些都一致的情况下才能成功解锁。因此，解锁模块16在采样指纹找到配对的情况下，判断采样指纹的在指纹检测单元12的位置是否与预存指纹在指纹检测单元12的位置一致。
在步骤S4中，解锁模块16在解锁密码一致的情况下解锁电子装置100。
在另外的较佳实施方式中，指纹解锁方法仍可以由指纹解锁系统10执行，并包括以下步骤：
S1：采样指纹；
S2：判断采样指纹是否为预存指纹；
S3：若采样指纹为预定指纹则判断采样指纹在指纹检测单元12或12a上的位置、出现次序及位置变化是否与预存指纹在指纹检测单元12或12a的预存位置、预存指纹的预存出现次序及预存指纹的预存位置变化是否一致；及
S4：若一致，解锁电子装置100。
本实施方式中，指纹解锁方法还包括以下步骤：
S0：设置并存储解锁密码，解锁密码包括预存指纹、预存指纹在指纹检测单元12或12a的预存位置、预存指纹的预存出现次序及预存指纹的预存位置变化。
其中，步骤S0可以由设定模块19、指纹检测单元12或12a及数据库14共同实现。步骤S1可以由指纹检测单元12或12a实现，步骤S2-S4可以由解锁模块16实现。
本实施方式中，以指纹检测单元12a为例，步骤S0包括：
S01：开启设定模式；
S02：采样依次施加到指纹检测单元12a同一位置的多个指纹；及
S03：保存多个指纹为预存指纹、所述位置为所述预存指纹的预存位置、多个指纹出现的次序为预存指纹的预存的出现次序，预存指纹的预存位置变化为固定。
在步骤S01中，电子装置100可以具有特定的按键或者按键组合，可以在按下后启动设定模块18并关闭解锁模块16，如此，只有设定模块18可以读取用户在指纹检测单元12a上的操作信息。另外，还可以设定，设定模式只有在解锁后才可以进行，防止安全漏洞。
在步骤S02中，多个指纹可以相同的指纹也可以是不同的指纹。以不同的指纹为例，用户可以将小指、无名指及中指依次放置到同一键区123a(例如“3”)，如此，指纹检测单元12a可以采样这些指纹并记录所在的键区123a(例如“3”)。也即是说，多个指纹为不同的指纹(即小指、无名指及中指的指纹)，所在的键区123a(例如“3”)为所述位置，而多个指纹出现的次序为(即依次为小指、无名指及中指的指纹)预存指纹的出现次序，由于只落在一个键区12(例如“3”)，因此，预存指纹的位置无变化，位置变化为固定。
在另外的实施方式中，多个指纹可以为相同的指纹，例如，用户可以将中指多次放置到同一键区123a(例如“3”)，如此，指纹检测单元12a可以采样中指指纹并记录所在的键区123a(例如“3”)。也即是说，多个指纹为相同的指纹，所在的键区123a(例如“3”)为所述位置，而多个指纹出现的次序实际上为中指指纹出现的次数。如此，为了检测指纹出现的次数，还可以定义指纹出现的间隔，例如1秒。如此，间隔1秒以上后重新检测到中指的指纹可以认为重新检测到指纹。由于只落在一个键区12(例如“3”)，因此，预存指纹的位置无变化，位置变化为固定。
在步骤S03中，以多个指纹为不同的指纹为例，即是说，小指、无名指及中指的指纹被识别后作为预存指纹存储起来，而小指、无名指及中指放置的键区123a(例如“3”)被标识为预存指纹的预存位置并存储起来，小指、无名指及中指的指纹依次出现的次序被标识为预存指纹的出现次序，而预存指纹的位置变化为固定。这些信息共同构成解锁密码并保存起来。
在步骤S03中，以多个指纹为相同的指纹为例，即是说，中指的指纹被识别后作为预存指纹存储起来，而中指放置的键区123a(例如“3”)被标识为预存指纹的预存位置并存储起来，而中指的指纹依次出现的次数被标识为预存指纹的出现次序，而预存指纹的位置 变化为固定。这些信息共同构成解锁密码并保存起来。
也即是说，在设定模式下，采集的指纹、采集的指纹在指纹检测单元12或12a的位置、采集的指纹的出现次序及采集的指纹的位置变化记录为解锁密码，并存储在数据库14。之后，电子装置100退出设定模式，设定模块19关闭，而解锁模块16启动。指纹检测单元12或12a重新采样指纹、指纹的位置、指纹的出现次序及指纹的位置变化，并与存储在数据库14中的预存指纹、预存指纹的预存位置、预存指纹的预存出现次序及预存指纹的预存位置变化比较，判断是否一致，若一致，则证明用户有权限，解锁模块16解锁电子装置100，允许用户使用电子装置100，若不一致，则证明为非法存取，解锁模块16不解锁电子装置100，用户无法操作、使用电子装置100。
在另外的实施方式中，以指纹检测单元12a为操作对象为例，步骤S0可以包括：
S01：开启设定模式；
S02：采样同时施加到多个不同位置的多个不同指纹；例如，用户可以将小指、无名指及中指同时放置到右侧面六个键区123a中的三个，而食指同时放置在顶侧面的三个键区123a中的一个，如此，指纹检测单元12a可以采样这些指纹并记录所在的键区123a；及
S03：保存多个不同指纹为预存指纹、多个不同位置为预存指纹的预存位置、预存指纹的预存出现次序为同时，预存指纹的预存位置变化为固定。即是说，小指、无名指、中指及食指的指纹被识别后存储起来，而小指、无名指、中指及食指放置的键区123a被标识为预存指纹的预存位置并存储起来。
在另外的实施方式中，以指纹检测单元12a为操作对象为例，步骤S0包括：
开启设定模式；
采样施加到指纹检测单元12a并滑动的指纹；例如，用户可以放置一个手指(例如食指)放置在指纹检测单元12a上并滑动。如此，指纹检测单元12a可以采样手指的指纹，并追踪指纹所在键区123a的变化，例如从“1”滑动经“2”到“3”；当然，用户也可以同时或依次放置多个手指到指纹检测单元12a并滑动，例如食指从“1”滑动经“2”到“3”，同时中指从“4”滑动经“5”到“6”，又或者食指从“1”滑动经“2”到“3”，随后中指从“4”滑动经“5”到“6”；及
保存指纹为预存指纹、指纹的位置为预存指纹的预存位置、指纹的出现次序为预存指纹的预存出现次序，指纹的滑动轨迹为预存指纹的预存位置变化。
当然，解锁密码的设定不限于本实施方式，还可以有其他的实施方式。
在其他实施方式中，步骤S0包括：
S01：开启设定模式；
S02：采样施加到指纹检测单元12a的指纹；及
S03：保存指纹为预存指纹、指纹在指纹检测单元12a上的位置为预存指纹的预存位置、指纹出现的次序为预存指纹的预存出现次序，指纹的位置变化为预存指纹的预存位置变化。
指纹可以为同一指纹或多个不同的指纹、指纹的位置可以为同一位置或不同位置、指纹的次序可以为同时或依次、指纹的位置变化可以为固定或变化。例如步骤S02可以包括采样依次施加到指纹检测单元12a同一位置的多个指纹；步骤S02可以包括采样多个同时施加到指纹检测单元12a多个不同位置的指纹；步骤S02可以包括采样施加到指纹检测单元12a并滑动的指纹。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
