如果所述接收的指纹的图像中有一个指纹特征数据与所述指纹密码中的一个指纹特征数据的相似度大于第二预设阈值，则所述指纹信息的这一指纹特征数据与所述指纹密码的这一指纹特征数据匹配，其中，所述第二预设阈值是根据试验确定的一个百分比值。在所述接收的指纹的图像的至少一个指纹特征数据是匹配的时，所述移动终端控制关闭所述超声波传感器10，所述移动终端的屏幕解锁。在屏幕解锁后，用户即可使用所述移动终端；在用户控制所述移动终端对其屏幕进行锁屏后，所述超声波传感器10重新启动。
所述超声波传感器10可布置在移动终端的外表面，也可以布置在移动终端的内部，为了移动终端的外观，并为了增大屏幕与其所在的表面的面积比从而相对地增大屏幕的面积或缩小移动终端的尺寸，在本实施例中，将所述超声波传感器10布置在移动终端的内部。
本申请提出的移动终端，通过超声波传感器10识别指纹，对移动终端的屏幕进行解锁，不仅能够获得用户的手指通过触摸移动终端的识别区域时输入的指纹的图像中的二维特征数据，还能够获得所述指纹图像中的三维特征数据，使得在用户手指有污渍或移动终端的识别区域上有污渍时，所述移动终端仍能够正确地根据指纹信息对所述移动终端的屏幕进行解锁，提高了移动终端通过识别指纹进行解锁屏幕的准确度。
以上仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程序/指令来实现其相应功能。本发明实施例不限制于任何特定形式的硬件和软件的结合。
本申请提出的根据指纹解锁屏幕的方法、系统及移动终端，通过超声波传感器识别指纹，对移动终端的屏幕进行解锁，不仅能够获得用户的手指通过触摸移动终端的识别区域时输入的指纹的二维特征数据，还能够获得所述指纹的三维特征数据，使得在用户手指有污渍或移动终端的识别区域上有污渍时，所述移动终端仍能够正确地根据指纹信息对所述移动终端的屏幕进行解锁，提高了移动终端通过识别指纹进行解锁屏幕的准确度。
