在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述
图1是本发明实施例的一种指纹验证的方法的流程图；
图2是本发明实施例的一种指纹验证的装置的结构示意图。
本发明的实施方式
指纹在给用户带来便捷的过程中，误触是一种很难避免的现象。用户在日常使用手机的过程中，用户取用手机的习惯、手指误触、潮湿的衣物都会很容易误触到指纹模组。比如用户平时从衣服口袋以及桌面取用手机的时候，采用正常的抓握习惯会不小心触碰到指纹模组；夏天天气较热，衣服容易出汗，用户将手机放入口袋中，潮湿的衣物触碰到衣服口袋里的手机，会触发指纹模组判断到手指按下，并进行采图验证等操作。当误触到指纹模组的时候，手机会按照正常流程进行指纹验证，误触指纹模组会产生指纹验证失败的效果，验证失败会用震动或者音效提示，震动、验证错误音效都会让 用户感觉不舒服，带来较差的体验；而且，在误触后，手机会进行指纹采图处理，每次判断到手指按下以及采图都会大幅度增加手机功耗。
本发明实施例提供了一种指纹验证的方法和装置，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的实施例仅仅用以解释本发明，并不限定本发明。
本发明实施例的一种指纹验证的方法是基于自学习功能的，该方法的流程如图1所示，包括以下步骤：
步骤s101，在录入指纹后，屏蔽防止指纹误触的功能。
可选的以手机作为终端，手机在录入完指纹数据之后，指纹验证次数为0，设定指纹在录入完后，验证N次为初步学习期。在初步学习期内，不根据当前指纹验证使能信息屏蔽指纹功能。
步骤s102，在每次指纹验证成功后，记录当前指纹验证使能信息。
所述当前指纹验证使能信息包括：方向信息、光感信息和时间信息中至少一种。其中方向信息可以通过陀螺仪数据或者加速度传感器数据获取，光感信息可以通过光感传感器的数据获取，时间信息可以通过时钟数据获取。可选的，在每次指纹验证成功后，手机记录手机的方向数据和光感数据。
步骤s103，根据记录的当前指纹验证使能信息，设定并存储标准指纹验证使能信息。
所述标准指纹验证使能信息包括：方向信息、光感信息和时间信息中的至少一种。
如，如果手机在一个方向处验证成功数超过预设值N，则将该方向加入手机方向集。在学习过程中，手机方向集中包含了可以使能指纹功能的多个方向姿态，手机方向集中的每个元素都代表手机的一种方向。可选的，假设在初步学习期内，获取到的手机方向集中有m个元素。
步骤s104，当指纹验证的次数达到预先设定的次数后，启动防止指纹误触的功能。可选的，指纹验证的次数达到初步学习期设定的N次后，启动防止指纹误触的功能。
步骤s105，获取当前指纹验证使能信息。
步骤s106，根据当前指纹验证使能信息，判断终端是否符合指纹验证使能条件；如果是，则转步骤s108，如果不符合，转步骤s107。具体的：当所述当前指纹验证使能信息与预先设定的标准指纹验证使能信息的差的绝对值小于预先设定的阈值时，所述终端符合指纹验证使能条件；当所述当前指纹验证使能信息与预先设定的标准指纹验证使能信息的差的绝对值大于或等于预先设定的阈值时，所述终端不符合指纹验证使能条件。
本实施例中，如果以方向信息作为指纹验证使能信息，当|V-Vi|<Vth时，使能指纹中断。其中，V为当前的手机方向，Vi为手机方向集中的一个元素(即标准手机方向)，Vth为预先设定的方向阈值。
如果以方向信息和光感信息作为指纹验证使能信息，当|V-Vi|<Vth，且|L-Li|<Lth时，使能指纹中断。其中，V为当前的手机方向，Vi为手机方向集中的一个元素(即标准手机方向)，Vth为预先设定的方向阈值；L为当前的光感值，Li为手机方向集中的一个元素(即标准光感值)，Lth为预先设定的光感阈值。
步骤s107，当不符合指纹验证使能条件时，屏蔽所述终端的指纹验证功能，并结束。
步骤s108，当符合指纹验证使能条件时，所述终端对指纹触摸进行正常验证。
步骤s109，当指纹验证成功后，记录当前指纹验证使能信息。可选的，每次验证成功，将手机的方向值和光感值记录到手机的方向集中。
步骤s110，根据记录的当前指纹验证使能信息，更新标准指纹验证使能信息，并转步骤s105。可选的，对手机方向集每个元素，用其对应的数组元素更新手机方向。经过多次指纹验证，手机方向集的每个元素会对应记录一组方向值、光感值数据：(Vi，Li)。每个数据表示指纹验证时用户手机的方向信息和光感信息。将Vi的平均值和Li的平均值更新该手机方向集元素。这样，随着用户的使用，该手机方向集将会越来越接近用户的实际使用情况。
本实施例中，步骤s101～s104为手机方向集的初步学习过程，在该过程中，录入指纹后的前N次验证期间，不进行指纹功能控制，每次验证成功就会记录手机的光感信息和方向信息，并统计出手机方向集用于后续的扩充。
本实施例中，步骤s105～s108为手机使用过程中指纹验证的控制过程，该过程中，该手机已有了方向集，当手机的方向处于一定的状态时，使能指纹验证功能。
本实施例中，步骤s109～s110为手机方向集的学习更新过程。在步骤s103中确定了手机的m个固定方向，这几个方向只是代表了大概的使能指纹功能的方向。考虑到用户指纹功能的使用是在一个很长的时间维度上(比如一个月，甚至更长)，所以需要在用户的使用过程中，需要不断更新手机方向。通过手机方向集的学习更新过程，可以实时更新用户的手机使用方向数据和手机使用光感数据，避免手机在其他非正常使用环境中指纹误触。如白天活动的时候，如果手机在口袋里，那么其方向值和光感值与手机方向集中的元素差异较大，就可以屏蔽掉指纹功能，避免手指误触。
本发明实施例还提供了一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现上述实施例所述的方法。

以手机为例，本实施例借助协处理器处理算法控制。在本实施例中，为手机增加一个协处理器(如ADSP(Audio Digital Signal Processing，音频数字信号处理器)或者sensor hub(传感器集成管理芯片))处理传感器数据，以及控制指纹传感器的功能使能和屏蔽，只有在适当的时候才唤醒CPU，从而达到降低误触率和降低功耗的目的。许多手机都已经集成了类似的协处理器。
在协处理器中获取手机的方向数据，该方向数据为陀螺仪数据或者加速度传感器数据。手机在休眠过程中，协处理器获取手机方向数据(光感数据为辅助数据，如果需要可以加入光感控制，如果不需要取消光感控制)，对手机方向数据进行初步处理。然后在协处理器中判断是否使能指纹功能。如果手机方向数据满足条件，则使能指纹中断，如果手机方向数据不满足条件，屏蔽指纹中断。这样就可以降低手机功耗，改善误触率。另外，本实施例通过记录用户指纹验证时的陀螺仪和光感传感器的数据，大概确定用户的使用习惯和使用环境。但由于用户在每天的不同时间使用习惯不同，因此可以增加时间维度的信息，以增加敏感度。
当指纹中断使能之后，指纹芯片就会不断轮询检测是否有手指按下，如 果手指按下，则捕捉一张指纹图像用于指纹图像识别。当指纹中断被屏蔽时，指纹芯片不再检测是否有手指按下，即使有手指按在传感器上，也不会去响应。
本实施例在实际使用过程中，手机的光感信息也可以表征用户的很多使用场景信息。如：用户夜间在床上玩手机的时候，手机的y轴方向向下。如果将该方向加入用户手机方向集，就会在白天用户不打算使用指纹的情况下出现误触反应。所以加入手机光感信息对手机方向信息作为补充，在特殊情况下，用户只有满足手机方向信息和手机光感信息，才可以使能指纹功能。手机的光感值记录在手机方向集元素对应的数组里，可以根据实际情况决定是否使用光感补充判断。
本发明实施例通过获取的当前指纹验证使能信息，判断是否是智能终端常用的使用状态，如果智能终端使用过程中不符合正常使用状态则屏蔽指纹验证功能，从而避免了智能终端在非正常使用环境中指纹误触，降低了智能终端的功耗，提高了用户体验度，具有便捷性、可操作性。
