图1为本发明一种实施例的终端设备密码解锁方法的流程图。
一种终端设备密码解锁方法，该方法应用于终端设备，该终端设备具有显示屏，该显示屏提供显示界面与用户交互，供用户执行相应操作以输入密码。如图1所示，其包括如下步骤：
S101：从显示于屏幕的多个候选信息集中获取被选定的的至少一个候选信 息集，每个候选信息集包含多个信息单元。
在终端设备的屏幕上预先显示多个候选信息集待选，每个候选信息集是由多个信息单元构成的信息集合，候选信息集的信息单元也显示在屏幕内。候选信息集具有预定显示区域，以使用户在该预定显示区域的操作可触发对该候选信息集的选定。在候选信息集被选定时，即表征对该候选信息集内所有信息单元的选定。
单个候选信息集所包含的信息单元可以多于或少于该密码的信息单元，因此，可以完全包含该密码的信息单元或者不包含该密码的任何一个信息单元。但是，该密码的所有信息单元应包含在所有候选信息集中，以使正确的候选信息集被选定时，终端设备可被解锁。如果密码的所有信息单元未包含在所有显示在屏幕上的候选信息集中，无论哪个候选信息集被选中，终端设备都无法被解锁。
用户在触摸显示屏上选定候选信息集，终端设备即获取到被选定的候选信息集。用户选定的候选信息集可以是一个或多个，因此，被选定的候选信息集可以是屏幕上多个候选信息集的部分或全部。
S102：依据被选定的所有候选信息集进行密码校验，当满足所述密码所具有的所有信息单元均包含于所有被选定的候选信息集中，每个被选定的候选信息集均包含所述密码所具有的至少一个信息单元，且所述被选定的候选信息集个数小于所述密码所具有的信息单元的总数时，确定密码校验成功。
在获取到被选定的候选信息集之后，对被选定的候选信息集进行校验，判定是否满足所述密码所具有的所有信息单元均包含于所有被选定的候选信息集中，是否同时满足每个被选定的候选信息集均包含所述密码所具有的至少一个信息单元，是否还满足被选定的候选信息集个数小于所述密码所具有的信息单元的总数。为了便于说明，将上述三个条件分别简称为第一条件、第二条件和第三条件。如果均满足上述三个条件，则确定密码校验成功。否则，确定密码校验失败。
具体而言，由于密码和候选信息集均是由信息单元构成的信息集合。可判定每个被选中的候选信息集是否与该密码存在交集，如果每个被选中的候选信息集均与该密码存在交集，则确定每个被选定的候选信息集均包含密码所具有的至少一个信息单元。同时，将所有被选中的候选信息集组合成新的集合，将新的集合与该密码进行交集运算，判定交集后所得结果是否为该密码，如果交 集结果为该密码，则确定密码所具有的所有信息单元均包含于所有被选定的候选信息集中。如果上述两个条件满足，且被选定的候选信息集个数小于所述密码所具有的信息单元的总数，则确定密码校验成功。
在一个示例中，在屏幕显示有六个候选信息集，该六个候选信息集分别是候选信息集A(1,3,6)，候选信息集B(2,6,7)，候选信息集C(8,6,0)，候选信息集D(9,3,2)，候选信息集E(5,8,0)，候选信息集F(4,3,9)，密码为1578，其具有四个信息单元。如果用户选定的为候选信息集A、B、C和D,由于候选信息集D未包含密码所具有的任何一个信息单元，则确定该次密码校验失败。如果用户选定的为候选信息集A、B和C，即便候选信息集A、B和C均包含密码所具有的至少一个信息单元，但该密码的信息单元5未包含在候选信息集A、B和C中，则确定该次密码校验失败。而在选择候选信息集A、B和E时，方才满足上述第一条件、第二条件和第三条件，从而使密码校验成功。
在一个示例中，在屏幕显示有四个候选信息集，该四个候选信息集分别是候选信息集A(1,3,4)，候选信息集B(2,6,7)，候选信息集C(8,6,0)和候选信息集D(9,3,2)，密码为2667。用户可仅选定候选信息集B，其满足上述第一条件、第二条件和第三条件，从而使密码校验成功。用户也可以选定候选信息集B、D或者选定候选信息集B、C，也均满足上述第一条件、第二条件和第三条件。
因此，由于每个候选信息集包含多个信息单元，单个候选信息集可包含两个以上的密码的信息单元，用户可以选定小于密码信息单元数量的候选信息集，同时并不需要考虑密码信息单元的排列顺序，从而简化了用户的操作，提升了其便捷性。同时，使得密码校验成功的候选信息集的组合也可能具有多种，可混淆他人对密码的破解，提升密码解锁的隐蔽性。
S103：若密码校验成功，解锁所述终端设备。
如果密码校验成功，则终端设备解除原有锁定状态。如果密码校验失败，则终端设备保持当前锁定状态。
在一种实施例中，步骤S101中获取被选定的显示于屏幕的至少一个候选信息集的步骤，具体为：获取被选定的显示于屏幕的至少一个候选信息集及其被选定的顺序；对应的，在依据被选定的所有候选信息集进行密码校验时，在依据被选定的所有候选信息集进行密码校验时，当满足每个被选定的候选信息集均包含所述密码所具有的至少一个信息单元，所述被选定的候选信息集个数小 于所述密码所具有的信息单元的总数，且依照候选信息集被选定的顺序排列所述被包含的至少一个信息单元所得结果与所述密码相等时，确定密码校验成功。
在获取被选定的候选信息集时，依据候选信息集被选定的时间，为被选中的候选信息集进行排序，先被选定的候选信息集排列在前，后被选定的候选信息集排列在后。
在依据被选定的所有候选信息集进行密码校验时，判定每个被选定的候选信息集是否均与所述密码存在交集，且判定被选定的候选信息集个数是否小于所述密码所具有的信息单元的总数，如果均存在交集且被选定的候选信息集个数小于所述密码所具有的信息单元的总数，从每个被选定的候选信息集与密码的交集中选取至少一个信息单元，依照候选信息集被选定的顺序排列这些被选取的信息单元，判定是否存在一种排列的结果与密码相等，如果相等，则确定密码校验成功。
具体而言，依据密码的信息单元的排列顺序和候选信息集被用户选中的顺序，从密码的当前信息单元和首个被选中的候选信息集开始，判定密码当前信息单元是否包含在当前被选中的候选信息集内，若不包含，则中断，若包含，继续判定密码的下一个信息单元是否包含在当前被选中的候选信息集内，若不包含，判定该下一位信息单元是否包含下一个被选中的候选信息集内，若不包含，则中断，若包含，继续上述判定，直至判定到密码的最后一个信息单元和最后被选中的候选信息集。
判定是否存在中断，若存在，则确定密码校验失败，若不存在，则确定密码校验成功。
在一个示例中，在屏幕显示有六个候选信息集，该六个候选信息集分别是候选信息集A(1,3,6)，候选信息集B(2,5,7)，候选信息集C(4,6,0)，候选信息集D(9,3,2)，候选信息集E(5,8,0)，候选信息集F(4,3,9)，密码为1578。如果用户选定的候选信息集依次为AEB，尽管所选定的候选信息集均与所述密码存在交集，且被选定的候选信息集个数小于所述密码所具有的信息单元的总数。但是，依据候选信息集被选定的顺序排列被包含的信息单元时，可从候选信息集A中选取1，从候选信息集E中选取5，从候选信息集B中选取7，从而排列成157，但与密码1578不同，所以密码校验失败。如果用户选定的候选信息集依次为ABE，从候选信息集集A中选取1，从候选信息集B中选取5和7，从候选信息集E中选取8，从而排列成1578，与密码1578相同，则密码校验成功。
因此，本实施例考虑了密码信息单元的排列顺序与候选信息集被选定的顺序的对应关系。在每个被选定的候选信息集均包含所述密码所具有的至少一个信息单元，所述被选定的候选信息集个数小于所述密码所具有的信息单元的总数时，还需要依照候选信息集被选定的顺序排列被包含的至少一个信息单元所得结果与所述密码相等，从而在简化操作的基础上，进一步提升了安全性。
在一种实施例中，候选信息集内的信息单元在屏幕内以位置固定的静态方式进行显示。所述的以位置固定的静态方式进行显示，是指信息单元的显示位置相对于其被包含的候选信息集固定不变，或者相对于所有候选信息集而形成的整体固定不变，而非限定于屏幕的预定位置不变。当用户调整所有候选信息集的显示位置时，信息单元的显示位置相对于屏幕发生了改变，但相对于其被包含的候选信息集固定不变。
当然，也可以限定信息单元的形状、大小或色彩固定不变。
在一种实施例中，至少一个候选信息集内的至少部分信息单元在屏幕内以位置变化的动态方式进行显示。可以是部分候选信息集内的部分或全部信息单元在屏幕内以位置变化的动态方式进行显示，或者所有候选信息集内的部分或全部信息单元在屏幕内以位置变化的动态方式进行显示。
所述以位置变化的动态方式进行显示，是指信息单元的显示位置在屏幕内实时或定时发生改变，从而以动态方式进行可视化显示。例如，在屏幕内滚动、转动或跳变显示。
因此，信息单元以位置变化的动态方式进行显示，将进一步提升密码的隐蔽性和混淆性。
下面将介绍几种以位置变化的动态方式进行显示的实施例。
在一种实施例中，如图2A和图2B所示，屏幕显示有四个候选信息集，该四个候选信息集均具有两个信息单元。其中，第一候选信息集101的信息单元为1和3，第二候选信息集102的信息单元为2和7，第三候选信息集103的信息单元为8和6，第四候选信息集104的信息单元为9和3。
图2A中，在某一时刻，仅显示了第一候选信息集101的信息单元1、第二候选信息集102的信息单元2、第三候选信息集103的信息单元8和第四候选信息集104的信息单元9。
预定时间后，如图2B所示，屏幕内显示了第一候选信息集101的信息单元3、第二候选信息集102的信息单元7、第三候选信息集103的信息单元6和第 四候选信息集104的信息单元3。此时的信息单元已更换，下一个预定时间后，各候选信息集将显示图2A中的信息单元，从而达到逐次循环显示的效果。
如果候选信息集内信息单元的数量为三个以上，也可设定在预定时间内显示两个以上的信息单元。预定时间的长短根据实际应用而确定，也允许用户根据自身需求设定该预定时间。
在一种实施例中，如图3A和图3B所示，信息单元20以屏幕内预定位置点为几何中心转动显示，具体而言，候选信息集10以该预定位置点为几何中心转动显示。
如图3A所示，屏幕内共有六个候选信息集10，该六个候选信息集10以屏幕内预定位置点为圆心排列成圆形，并绕该预定位置点转动。
如图3B所示，屏幕内共有五个候选信息集10，预定位置点为其中一个候选信息集，该候选信息集的位置固定，其他四个候选信息集围绕在该位置固定的候选信息集四周，并绕该位置固定的候选信息集转动。
当然，也可设定多个候选信息集的位置固定，其他候选信息集绕这些位置固定的候选信息集转动。需要说明的是，为了便于用户识别，应设置较为合适的转动速度。同时，在终端设备内提供相应的设置选项，使用户可设置相应的转动速度或转动方向。
在一种实施例中，所有信息单元在候选信息集内以随机游动的动画方式予以显示。同时，信息单元的色彩、大小也会随机发生变化。如果信息单元为数字、字母或文字，也可设定数字、字母或文字的字体随机发生变化。
上述实施例中，信息单元的动态显示有助于提升密码的隐蔽性和混淆性。但是，在一定程度上也不便于用户识别和选中候选信息集。因此，在本实施例中，在候选信息集被选定时，信息单元转变为以位置固定的静态方式进行显示。
具体而言，实时检测是否存在对候选信息集的选定，如果存在，信息单元即转变为以位置固定的静态方式进行显示。例如，在界面锁屏时，终端设备会实时检测其触摸屏是否存在触压，如果存在触压，信息单元即转变为以位置固定的静态方式进行显示。如果这种触压在预定时间内中断，信息单元又从静态方式转变为动态方式进行显示。
因此，本实施例在提升密码的隐蔽性和混淆性的同时，兼顾用户识别和选中候选信息集的便利性，有利于提升用户体验。
在上述实施例的基础上，本实施例中，每个候选信息集内的信息单元被限 制在屏幕的特定显示区域进行显示，在该特定显示区域内的选定操作将触发对该特定显示区域所对应的候选信息集的选定。该特定显示区域具有对应的特定显示边界，该特定显示边界可不显示在屏幕内。或者，为了便于用户的识别，该特定显示边界进行显性的可视化显示，例如以特定的边界线进行显示。
其中，特定显示区域的形状包括但不限于圆形、多边形和圆弧形。同时，信息单元在该特定显示区域内呈直线、并列、三角形或其他形状进行排列显示。多个候选信息集的特定显示区域呈同心圆、圆形、点阵、并列或其他几何关系进行设置。特定显示区域的形状、多个信息单元在特定显示区域内的排列和候选信息集的特定显示区域所呈现的显示形状可任意组合。
当然，为了向用户提供较佳的视觉体验，便于用户识别和选中候选信息集，应该依据特定显示区域的形状、多个信息单元在特定显示区域内的排列和候选信息集的特定显示区域所呈现的显示形状进行合理配置。例如，多个候选信息集的特定显示区域呈点阵的几何关系进行设置时，可设定特定显示区域的形状包括为圆形；特定显示区域的形状为矩形时，可设定信息单元在该特定显示区域内呈直线进行排列显示，且多个候选信息集的特定显示区域呈并列的几何关系进行设置。
图4A-4C给出了几种相关示例。
图4A中，并未示出特定显示边界，多个信息单元20紧凑地排列在一起，紧凑排列的多个信息单元20构成一个候选信息集，便于用户识别。
图4B中，特定显示边界11以边界线的形式进行了显示，特定显示边界11围合形成了圆形的特定显示区域12，且多个候选信息集的特定显示区域12呈点阵的几何关系进行设置。
图4C中，特定显示区域12呈长条的矩形，该特定显示区域12的多个信息单元20呈直线排列，多个候选信息集的特定显示区域12呈并列的几何关系。
在一种实施例中，候选信息集基于用户的选定指令而被选定，选定指令的输入源由麦克风、陀螺仪、物理按键、触摸屏、摄像头、红外线传感器、震动传感器中任意一种或多种提供。
在一种实现方式中，用户在触摸屏上与候选信息集的接触将触发选定指令，例如，用户在触摸屏上点击、滑动或按压候选信息集。触摸屏实时检测其表面是否存在接触，如果存在接触且该接触位置处于候选信息集的显示范围内，则该候选信息集被选定。
在一种实现方式中，终端设备设有麦克风，终端设备获取用户输入的语音，从输入的语音中识别关键字，如果该关键字与某个候选信息集的预设关联字对应，则该候选信息集被选定。为了便于用户使用，关联字应具有唯一性和一定的顺序关系。例如，候选信息集在屏幕内呈直线顺次排列，设定候选信息集的关联字为其排列序号，若用户输入的语音中包含序号，则对应于该序号的候选信息集被选用。终端设备也可以提供相应的选项，供用户设定候选信息集的关联字。
当然，也可以通过其他方式来触发选定指令，例如：通过摄像头捕捉用户某个特定手势或者某个预定目视动作、通过陀螺仪检测用户对终端设备水平状态的某个特定操控、通过震动传动器识别到用户对终端设备的摇晃、通过红外传感器检测到用户的一个特定手势、通过识别一个或多个物理按键处于导通状态等。
在一种实施例中，信息单元为字符、色彩、字体、字号、图案和图像中的任意一种或任意多种信息元的结合。对应的，密码的信息单元也是字符、色彩、字体、字号、图案和图像中的任意一种或任意多种信息元的结合。其中，字符可以是文字、数字、字母或符号等，色彩可以是红色、黑色等常见的十二中颜色，字体可以是常见的楷体、宋体或黑体等，图案可以是三角形、圆形、梅花形等特定形状的图案。需要说明的是，为了便于用户识别，不同信息单元的信息元应具有较好的识别性，不宜设置较为相似的信息元。例如，信息元为色彩时，如果某一个信息单元为粉红色，就不宜设置其他信息单元为浅红色、深红色等较为相似的颜色，而应设置为绿色或黑色等相差较大的颜色。
当仅采用一种信息元构成信息单元时，信息单元的信息元即为该信息单元的全部，在判定被选定的候选信息集是否包含密码所具有的至少一个信息单元时，是将密码的每个信息单元的信息元与候选信息集内每个信息单元的信息元进行比较，如果存在相同，则确定被选定的候选信息集是否包含密码所具有的至少一个信息单元。同理，在判定密码所具有的所有信息单元是否均包含于所有被选定的候选信息集中时，将密码的每个信息单元的信息元逐个与候选信息集内每个信息单元的信息元进行比较，如果均相同，则确定密码所具有的所有信息单元是否均包含于所有被选定的候选信息集中。
为了进一步提升安全性和隐蔽性，每个信息单元应结合两种或两种以上的信息元。在验证候选信息集的信息单元是否与密码的信息单元相同时，逐一验 证其信息元是否相同，当且仅当候选信息集的信息单元的所有信息元与密码的信息单元的所有信息元均相同时，才确定二者相同。
鉴于色彩和字符的辨识度较高，将以信息单元为带有色彩的字符为例。例如，密码的一个信息单元为红色的“1”，候选信息集内包括红色的“2”、黑色的“1”和红色的“1”，由于红色的“2”和黑色的“1”均包含了不同的信息元，则不与该密码的信息单元相同，当且仅当候选信息集内信息单元的色彩为红色且为数字“1”时，确定二者相同，则该候选信息集包含了密码的信息单元。当然，信息单元也可以是色彩和图案、字符和字体等信息元的组合。例如，信息单元为黑色的字母“C”、蓝色的正楷字体的汉字“王”。
在一种实施例中，部分候选信息集内信息单元的个数与其他候选信息集内信息单元的个数不同，或者，全部候选信息集内信息单元的个数均不相同。例如，在屏幕内显示四个候选信息集，其中两个候选信息集内含有三个信息单元，另外两个候选信息集分别含有一个和两个信息单元。从人的角度出发，信息单元数量的不同会对人产生误导，从而可提升混淆性和安全性。
进一步的，可将各候选信息集内信息单元的数量按照一定的规律进行设置，例如，在屏幕内显示四个候选信息集，四个候选信息集内信息单元的数量分别为一个、两个、三个和四个。从人的角度出发，信息单元的规律排列会让人理解为与密码相关，从而做出错误判定，可进一步提升混淆性和安全性。
在一种实施例中，在步骤S101:获取被选定的显示于屏幕的至少一个候选信息集的步骤之前，还包括以下步骤：随机设定候选信息集内的信息单元。
随机设定候选信息集内的信息单元后，每次在屏幕内显示的信息单元都是随机的，因此，上一次锁屏界面内的信息单元和下一次屏幕界面内的信息单元极有可能不同，他人更加难以从变化的信息单元中破解密码，从而可提升隐蔽性和安全性。需要说明的是，这种随机设定并非是任意设定，随机设定后的候选信息集内的信息单元应该仍然包含密码的信息单元，以使用户在选中了正确的候选信息集之后，可以通过密码校验。如果这个随机设定是任意的，可能导致终端设备无法解锁。同时，这种随机设定是在完成一次密码校验，解锁终端设备之后，显示下次锁定界面之前所执行的。对于单次解锁而言，如果用户选定的候选信息集不正确，密码校验失败后，此时并不会随机设定候选信息集的信息单元，而是解锁成功后，对信息单元进行随机设定。
具体而言，随机设定信息单元是指随机设定信息单元的信息元。可更改信 息元、增加信息元的种数和/或减少信息元的种数。
在一种实现方式中，可随机改变信息单元的信息元，但不改变信息元的类别。在一种示例中，信息单元为具有色彩的字符。例如，屏幕上显示有三个候选信息集，第一个候选信息集包含黑色的“1”和红色的“2”，第二个候选信息集包含蓝色的“5”和绿色的“3”，第三个候选信息集包含黑色的“7”和紫色的“4”。当本次密码校验成功后，下次可设定第一个候选信息集包含黑色的“8”和红色的“2”，第二个候选信息集包含红色的“5”和绿色的“3”，第三个候选信息集包含黑色的“7”和紫色的“4”。可以看出，第一个候选信息集内信息单元的字符发生了变化，第二个候选信息集内信息单元的色彩发生了变化，而构成上述信息单元的信息元仍然是色彩和字符，其种类并未发生变化。
在一种实现方式中，可增加信息元的种数，即增加了信息元类别的数量。在一种示例中，信息单元为具有色彩的字符。例如，屏幕上显示有三个候选信息集，第一个候选信息集包含黑色的“A”和红色的“B”，第二个候选信息集包含蓝色的“C”和绿色的“F”，第三个候选信息集包含黑色的“E”和紫色的“K”。当本次密码校验成功后，下次可设定第一个候选信息集包含黑色的“三角形”和红色的“B”，第二个候选信息集包含蓝色的“C”和绿色的“F”，第三个候选信息集包含黑色的“E”和紫色的“五角星”。可以看出，在具有色彩和字符这两种信息元的基础上，第一个候选信息集和第三个候选信息集内信息单元增加了图案这一新的信息元。
在一种实现方式中，可减少信息元的种数，即减少了信息元类别的数量，具体而言，是减少了单个候选信息集内信息元的类别数量。在一种示例中，信息单元为具有色彩的字符。例如，屏幕上显示有三个候选信息集，第一个候选信息集包含黑色的“三角形”和红色的“B”，第二个候选信息集包含蓝色的“C”和绿色的“F”，第三个候选信息集包含黑色的“E”和紫色的“五角星”。当本次密码校验成功后，下次可设定第一个候选信息集包含黑色的“A”和红色的“B”，第二个候选信息集包含蓝色的“C”和绿色的“F”，第三个候选信息集包含黑色的“E”和紫色的“K”。可以看出，减少了信息单元原有的图案信息元。
在一种实施例中，上述随机设定候选信息集内的信息单元的步骤，具体为：随机设定候选信息集内信息单元的个数。具体而言，可增加或减少候选信息集内信息单元的个数。例如，屏幕上显示有三个候选信息集，第一个候选信息集包含三个信息单元，第二个候选信息集包含两个信息单元，第三个候选信息集 包含四个信息单元。当本次密码校验成功后，下次可设定第一个候选信息集包含五个信息单元，第二个候选信息集包含三个信息单元，第三个候选信息集包含两个信息单元。
在一种实施例中，在步骤S101:获取被选定的显示于屏幕的至少一个候选信息集的步骤之前，还包括以下步骤：随机设定候选信息集的个数。随机设定候选信息集的个数后，每次在屏幕内显示的候选信息集的个数都是随机的，因此，上一次锁屏界面内的候选信息集的个数和下一次屏幕界面内的候选信息集的个数极有可能不同，从而可提升隐蔽性和安全性。当然，这种随机设定并非是任意设定，随机设定后的候选信息集内的信息单元应该仍然包含密码的信息单元，以使用户在选中了正确的候选信息集之后，可以通过密码校验。
上述几种实施例仅仅是本发明的几种示例，在显示锁屏界面之前可以对信息单元的个数、信息单元的信息元和候选信息单元的个数中任意一种或多种的组合进行随机设定。同时，也应在终端设备内提供相应的选项，用户可根据自身需要，对信息单元的个数、信息单元的信息元和候选信息单元的个数中任意一种或多种的组合进行设定。
图5为本发明一种实施例的终端设备密码解锁方法的流程图。
一种终端设备密码解锁方法，应用与终端设备，其包括如下步骤：
S201：在屏幕显示多个候选信息集，每个候选信息集包含多个信息单元；
在终端设备的屏幕上预先显示多个候选信息集待选，每个候选信息集是由多个信息单元构成的信息集合，候选信息集的信息单元也显示在屏幕内。单个候选信息集所包含的信息单元可以多于或少于该密码的信息单元，因此，可以完全包含该密码的信息单元或者不包含该密码的任何一个信息单元。但是，该密码的所有信息单元应包含在所有候选信息集中，以使正确的候选信息集被选定时，终端设备可被解锁。如果密码的所有信息单元未包含在所有显示在屏幕上的候选信息集中，无论哪个候选信息集被选中，终端设备都无法被解锁。
S202：获取用户的连续触压指令，确定该连续触压指令所选定的候选信息集；
检测用户在触摸显示屏上的连续滑动操作，从而产生连续触压指令。候选信息集具有预定显示区域，以使用户在该预定显示区域的滑动操作可触发对该候选信息集的选定。因此，连续滑动操作所经过的预定显示区域相应的候选信息集即被选定。用户选定的候选信息集可以是一个或多个，因此，被选定的候 选信息集可以是屏幕上多个候选信息集的部分或全部。
S203：依据被选定的所有候选信息集进行密码校验时，当满足所述密码所具有的所有信息单元均包含于所有被选定的候选信息集中，且每个被选定的候选信息集均仅包含所述密码所具有的一个信息单元，确定密码校验成功；
在确定被选定的候选信息集之后，对被选定的候选信息集进行校验，判定是否满足所述密码所具有的所有信息单元均包含于所有被选定的候选信息集中，是否同时满足每个被选定的候选信息集均仅包含所述密码所具有的一个信息单元。若满足，则确定密码校验成功。
在一个示例中，在屏幕显示有四个候选信息集，该四个候选信息集分别是候选信息集A(1,3,6)，候选信息集B(2,6,7)，候选信息集C(8,6,0)和候选信息集D(9,3,2)，密码为1789。如果用户选定的为候选信息集A、B、C和D,密码的信息单元1789均包含于候选信息集A、B、C和D中，同时，候选信息集A、B、C和D均只包含了密码的一个信息单元。因此，本次密码校验成功。
S204：若密码校验成功，解锁所述终端设备。
如果密码校验成功，则终端设备解除原有锁定状态。如果密码校验失败，则终端设备保持当前锁定状态。
图6为本发明一种实施例的终端设备密码解锁装置的结构示意图。
如图6所示，该终端设备密码解锁装置包括获取模块401、校验模块402和解锁模块403。获取模块401用于从显示于屏幕的多个候选信息集中获取被选定的的至少一个候选信息集，每个候选信息集包含多个信息单元。校验模块402用于依据被选定的所有候选信息集进行密码校验，当满足所述密码所具有的所有信息单元均包含于所有被选定的候选信息集中，每个被选定的候选信息集均包含所述密码所具有的至少一个信息单元，且所述被选定的候选信息集个数小于所述密码所具有的信息单元的总数时，确定密码校验成功。解锁模块403用于在密码校验成功时，解锁所述终端设备。
在一种实施例中，获取模块401用于从显示于屏幕的多个候选信息集中获取被选定的的至少一个候选信息集及其被选定的顺序；对应的，校验模块402用于在依据被选定的所有候选信息集进行密码校验时，当满足每个被选定的候选信息集均包含所述密码所具有的至少一个信息单元，所述被选定的候选信息集个数小于所述密码所具有的信息单元的总数，且依照候选信息集被选定的顺序排列所述被包含的至少一个信息单元所得结果与所述密码相等时，确定密码 校验成功。
