为使本公开的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本公开进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本公开，并不用于限定本公开。
需要说明，若本公开实施例中有涉及方向性指示(诸如上、下、左、右、前、后……)，则该方向性指示仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本公开实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本公开要求的保护范围之内。
随着科技的持续发展和手机的不断升级，手机更趋向于设计的更薄、更大，使人们在携带手机时不会觉得太重，但在使用手机时却能够享受其大屏高清的显示效果。但无论手机如何更新换代，其基础的接打电话、拍照视频、息屏上锁功能却无法被替代。
市面上现有的主流的锁屏解锁方案包括：数字键盘锁、电容指纹解锁、光学指纹解锁、超声波指纹解锁、面部识别以及虹膜识别等解锁方式。但在这其中数字键盘解锁的保密程度较低，无法达到现在人们对于隐私保护的需求；利用电容指纹解锁方式的手机通常需将电容指纹采集模块置于手机的侧面或背面，较占用手机外壳的位置同时影响美观，且侧置的电容指纹采集模块会极大的影响手机轻薄化的问题；光学指纹解锁以及超声波指纹解锁仅能够在较小的屏幕范围内实施，无法做到自由的进行解锁，且部分屏下指纹解锁也并不是特别的安全，对于一些别有用心的人只要采集到指纹就可以根据指纹信息解锁手机；最后的面部识别以及虹膜识别在解锁时都必须将摄像头对准脸或眼睛，且需要等待摄像头采集人脸或人眼信息，时间较长且过程繁琐。现有技术中除了上述这些解锁方式外没有其他的兼顾解锁便利性、成本还具有一定保密性的解锁方案。
为了解决上述问题，本公开实施例提供一种移动终端触控解锁处理方法，根据本实施例的移动终端触控解锁处理方法可以自动识别用户在多个手指同时触击屏幕时各手指与屏幕的接触面积，各手指在屏幕上落点的间距以及相对的位置关系，各手指落下的时间间隔以及其他的手势特征，通过分析上述手势特征是否与预设的手势特征相符，对移动终端进行解锁操作。使用户可通过全屏幕任何角度进行解锁，且因为是根据用户的行为习惯进行识别解锁的，所以无法轻易的破解，给用户带来便利的解锁体验的同时保护了用户的隐私安全性。
示例性方法
第一实施例
如图1中所示，本公开实施例提供一种移动终端触控解锁处理方法，所述移动终端触控解锁处理方法可用于手机、平板电脑等移动设备中。在本公开实施例中所述方法包括如下步骤：
步骤S100、判断是否检测到用户至少两个手指头敲击触摸屏的操作；
在本实施例中，当移动终端处于锁屏状态下，判断所述移动终端的屏幕是否接收到有两个或两个以上的手指头敲击屏幕，由移动终端的角度则判断屏幕在短时间内是否连续检测到屏幕区域有两个或两个以上的位置的电学参数发生变化，所述电学参数包括电容值、电阻值等常用于检测用户对触摸屏进行操作的触摸屏领域的参数。
其中，在所述判断是否检测到用户至少两个手指头敲击触摸屏的操作的步骤之前包括：
预先采集用于解锁移动终端的同一用户的至少两个手指头同时敲击屏幕触摸的手指特征信息，并存储。
进一步地，所述至少两个手指头的手指特征信息包括：
至少两个手指头中每个手指头在触摸屏区域占的面积信息；
各个手指头间在触摸屏区域相互的位置信息；
各个手指头在触摸屏区域相互的点击时间差信息。
在移动终端接收到用户的解锁操作之前需要先将用户用于解锁移动终端的手指特征信息进行采集并存储在移动终端存储空间中。所述移动终端采集手指特征信息的步骤具体包括：移动终端接收到开启解锁手指录入界面开启的操作指令后，控制开启解锁手指录入界面；当开始解锁手指录入时，检测到用户至少两个手指头多次敲击触摸屏的操作，移动终端经过多次采集用户的多个手指头敲击触摸屏的操作，得到体现用户多手指解锁时手势习惯以及力度习惯的手指特征信息，具体包括至少两个手指头中每个手指头在触摸屏区域占的面积信息、各个手指头间在触摸屏区域相互的位置信息、各个手指头在触摸屏区域相互的点击时间差信息等，并将所述手指特征信息存储在移动终端对应的存储空间中，并可注明参与解锁的手指的数目以便用户对录入的手指特征信息进行编辑。
举例说明，例如用户A开启手机设置中的手指录入界面，并根据提示选择使用食指、中指以及无名指三个手指头进行手指特征信息的录入，则用户以用户习惯的自然地手型和力度重复提起和敲击屏幕，进一步地可以通过旋转手机屏幕的角度重复采集手指特征信息的方式提高采集精度，采集完毕后手机将录入的第一手指特征信息存储在手机的存储空间中，并标明为三个手指头的手指特征信息。例如采集得到的信息包括，第一手指头部分的面积为A1、第二手指头部分的面积为A2以及第三手指头部分的面积为A3；以第一手指头为坐标原点，较佳的采用极坐标系对另外两手指进行相对位置的测算，例如第二手指头的极坐标为(距离1，角度1)，第三手指头的极坐标为(距离2，角度2)，由此得到三个手指头敲击点的相对位置。除极坐标系之外也可使用任何能够表示各手指头相对位置的方式进行记录，例如直角坐标系等；以第一手指头敲击手机屏幕的时间记为0，则第二手指头敲击到手机屏幕的时间记为t1、第三手指头敲击到手机屏幕的时间记为t2。则通过算法，当实际使用中，有三个手指头对手机进行解锁操作时，通过以上三个手指特征信息参数中任意一个或任意几个的组合对采集到的解锁手势进行判断。
除了面积、相对位置信息、点击时间差信息以外还可以通过任何能够表示用户手势特征的参数进行识别，例如通过压力传感器检测各个手指的敲击力度，各个手指敲击时接触面积的变化速率等多种参数。
进一步地、步骤S200，当检测到用户至少两个手指头敲击触摸屏的操作，则获取当前敲击触摸屏的至少两个手指头的手指特征信息；
在本实施例中，当检测到用户有至少两个手指头敲击触摸屏的操作时，获取当前敲击触摸屏的至少两个手指头的手指特征信息，在移动终端的角度为，获取至少两个位置的电学参数变化值所对应的敲击点的面积信息、位置信息以及时间信息。
举例说明，仅使用食指一只手指敲击手机电容屏幕时，因为手机触摸屏仅检测到有一个位置产生电容变化，所以并不符合解锁条件；当手机被抓在手中或放在口袋里因为误触产生大面积的电容值变化时也不符合解锁条件；而仅有在0.5秒或更短的时间内连续获取到至少两个手指敲击手机触摸屏的情况下，即手机触摸屏连续检测到有两个以上的位置产生电容变化则获取该电容变化值并将其转换为手指特征信息中的敲击面积、位置坐标以及时间信息。
进一步地，步骤S300、将获取的当前敲击触摸屏的至少两个手指头的手指特征信息与预先录入的用于解锁移动终端的至少两个手指头的手指特征信息进行匹配判断，当匹配成功则控制解锁移动终端。
在本实施例中，移动终端将获取的至少两个手指头敲击移动终端触摸屏时的手指特征信息与预先录入的用于解锁移动终端的对应数量的手指头的手指特征信息进行比对判断，当当前敲击触摸屏时采集到的手指特征信息与预先录入的手指特征信息匹配成功时解锁移动终端，所述匹配成功的条件可以是当前采集的后置特征信息与录入的手指特征信息的相似度超过80％等条件，则当当前敲击触摸屏时采集到的手指特征信息与预先录入的手指特征信息相似度达到80％以上则解锁移动终端；当判断相似度低于预设的数值时不解锁移动终端，并且在连续多次解锁失败时对操作者进行提示，在继续失败三次或五次后将锁定移动终端一个小时等，进一步提高移动终端的安全性。
举例说明，当获取到的手指头敲击触摸屏时的手指特征信息为第一手指头的面积为A4、第二手指头的面积为A5以及第三手指头的面积为A6；获取到第一手指头敲击位置为手机中央，第二手指头的极坐标为(距离3，角度3)，第三手指头的极坐标为(距离4，角度4)；第二手指头敲击屏幕的时间为t3，第三手指头敲击屏幕的时间为t4。 当手机将上述信息与手机中预设的三个手指头解锁移动终端的手指特征信息A1、A2、A3、(距离1、角度1)、(距离2、角度2)、t1、t2相比对时，若规定通过算法计算当与预设值相似度达到80％以上时则为匹配成功，解锁手机，当与预设值相似度低于80％时则为不匹配，保持手机锁定状态。
在第二实施例中，在识别手指特征信息的基础上指纹识别使得移动终端的安全性在第一实施例方案的基础上进一步加强，如果需要破解该手机除了需要获取用户的多个手指指纹外，还需要知道用户手势习惯以及按压力度的习惯，即使是同一个手指头上的指纹，也有常用于解锁的一部分和不常用于解锁的一部分，例如手机用户习惯于将手指头立起进行敲击，则在录入的手指特征信息中就几乎不存在指腹以下位置的指纹，若是有不怀好意的人简单的将制作的指纹按照相应位置放置在手机屏幕上，则同样无法解锁手机。
如图2所示，为用户预设手指特征信息时的示意图，参与解锁的手指头包括A、B、C、D、E五只手指头，并获取该五只手指头实际触碰屏幕时的指纹信息、面积信息、坐标信息以及相对时间信息，分别为指纹A、指纹B、指纹C、指纹D、指纹E；面积Sa、Sb、Sc、Sd、Se；以屏幕中心为原点的坐标信息(Xa，Ya)、(Xb,Yb)、(Xc，Yc)、(Xd，Yd)、(Xe，Ye)；以及相对下落时间，当B为最先下落的手指头时计Tb＝0s，则其他手指头的相对下落时间为Ta、Tc、Td、Te。
当用户实际使用五只手指头对手机进行解锁时，如图3所示。首先将指纹信息和其与的手指特征信息分开，可先判断指纹信息是否符合预设的手指特征信息，若不符合则直接判断解锁失败；或先通过其他的手指特征信息判断是否为预设的手指特征信息再判断指纹是否匹配，则当前采集的用于解锁手机屏幕的手指特征信息中，手指头B依然为最先下落的手指则当前获取的用于检索的手指头下落时间Tb’＝0s，且采用直角坐标系的方式对五只手指头的相对位置进行识别，通过判断得到当前五只手指头的相对位置信息与预设的手指特征信息中的相对位置信息基本符合，相似度达到90％以上，和/或各手指头按压的面积Sa’、Sb’、Sc’、Sd’、Se’的大小也与预设的手指特征信息基本符合，相似度达到83％，和/或各手指头下落时间间隔Ta’、Tc’、Td’、Te’也基本与预设的手指特 征信息匹配成功，通过以上三项中任一项或任意一项以上的组合进行判断得到当前识别的手指特征信息匹配成功，则进一步识别指纹是否也与预设的手指特征信息相符，若进一步匹配成功则控制手机解锁。通过在手指特征信息中加入指纹识别信息的方式进一步提高了用户在使用移动终端解锁功能时的安全性，不用担心移动终端通过指纹的方式被解锁，提高用户的使用体验。
