移动终端和屏幕解锁方法、装置 技术领域
本申请涉及通信领域，具体涉及一种移动终端和屏幕解锁方法、装置。
背景技术
在现有技术中，目前移动终端进行解锁主要是通过输入正确的密码来实现解锁，但是用户每次开机进入系统时需要重新输入解锁密码，这样比较麻烦，同时，由于输入密码极容易泄露，给用户带来了不安全的隐患。另外，移动终端上也开始采用了指纹式的识别解锁方式，这需要添置新的用于识别指纹的硬件，导致成本的提升，且若移动终端上录入了其他人的指纹，则其他人也能凭借指纹来对移动终端进行解锁，也给用户带来了不安全的隐患。
发明内容
本申请的主要目的为提供一种屏幕解锁方法和装置，旨在解决现有的解锁技术中的利用密码解锁时密码易泄露，而利用指纹解锁时安全性不高的技术问题。
为了实现上述申请目的，本申请提出一种移动终端，包括处理器和存储器，
所述存储器用于存储程序；
所述处理器被配置为用于执行所述存储器中存储的程序，所述程序被执行时，实现以下步骤：
接收解锁触发指令后，开启摄像头获取用户当前的指纹图像；
接受用户发出的图像匹配指令，以调出本地保存的指纹照片；
将所述指纹图像与所述本地保存的指纹照片进行匹配比对；
若匹配成功，将屏幕解锁。
为了实现上述申请目的，本申请提出一种屏幕解锁方法，应用于移动终端，所述方法包括步骤：
接收解锁触发指令后，开启摄像头获取用户当前的指纹图像；
将所述指纹图像与本地保存的指纹照片进行匹配比对；
若匹配成功，将屏幕解锁。
本申请还提供一种屏幕解锁装置，应用于移动终端，所述装置包括：
第一获取模块，用于接收解锁触发指令后，开启摄像头获取用户当前的指纹图像；
匹配模块，用于将所述指纹图像与本地保存的指纹照片进行匹配 比对；
解锁模块，用于若匹配成功，将屏幕解锁。
本申请有益技术效果：本申请通过在接收到解锁触发指令后，开启摄像头获取用户当前的指纹图像，再将用户当前的指纹图像与本地保存的指纹照片进行匹配比对，只有当所述获取到的用户当前的指纹图像与本地保存的指纹照片符合匹配要求时，才可以认定当前用户合法完成解锁。由于指纹具有唯一性、遗传性和不变性，每个人的指纹也是独一无二，如果获取的指纹图像内的指纹不是用户本人的指纹，则无法解锁移动终端，大大提高了屏幕解锁的安全性。

图2为本申请一实施例的屏幕解锁装置的结构示意图；
图3为本申请一实施例的移动终端的结构示意图。
本申请目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用于解释本申请，并不用于限定本申请。
参照图1，本申请一实施例的屏幕解锁方法，应用于移动终端，所述方法包括步骤：
S1：接收解锁触发指令后，开启摄像头获取用户当前的指纹图像。
S2：将所述指纹图像与本地保存的指纹照片进行匹配比对。
S3：若匹配成功，将屏幕解锁。
如上述步骤S1所述，用户在需要解锁移动终端时，可通过触发相应按键，或者当检测到用户的指定操作(例如将手指靠近摄像头)来生成解锁触发指令，进而进入移动终端的解锁界面，此时摄像头会启动，并用来获取用户当前的指纹图像。
如上述步骤S2所述，本地保存有用户预先保存的指纹照片，本步骤需要将获取到的指纹图像与本地的指纹照片进行匹配比对，具体实现时，可以由用户在解锁界面上通过按钮触发来发出图像匹配指令，从而调用出预存于本地的指纹照片，来与当前获取到的指纹图像进行图像匹配，或者由用户通过按下移动终端的指定按键(例如音量增大键或音量减小键)来发出图像匹配指令，调用出预存于本地的指纹照片来与当前获取到的指纹图像，来与当前获取到的指纹图像进行图像匹配，本实施例不作具体限定。
如上述步骤S3所述，只有当所述获取到的用户当前的指纹图像与本地保存的指纹照片符合匹配要求(符合匹配要求具体可为用户当前的指纹图像与本地保存的指纹照片的相似度大于某一预设阈值，例如90％)，才可以认定当前用户合法完成解锁。由于指纹具有唯一性、遗传性和不变性，尚未发现有不同的人拥有相同的指纹，所以每个人的指纹也是独一无二。因此，利用获取指纹图像，并将指纹图像与用户预先存储的指纹照片进行匹配比对，如果获取的指纹图像内的指纹不是用户本人的指纹，则无法解锁移动终端，提高了屏幕解锁的安全性。
进一步地，本申请一实施例中，步骤S1之前，包括：
S100：获取用户每一个手指对应的至少一张指纹照片。
S101：从所述每一个手指对应的至少一张指纹照片中，筛选出每一个手指对应的轮廓最清晰的一张指纹照片。
S102：将左手手指的指纹对应的各指纹照片标记为左手特定指纹照片，将右手手指的指纹对应的各指纹照片标记为右手特定指纹照片。
如上述步骤S100至S102所述，由于每个人的每一个手指的指纹都是不相同的，所以包含每根手指对应的指纹照片都可以用来用作预先保存的用户的指纹图像。在对每根手指进行拍摄来获取对应的指纹照片时，对于每根手指，可以拍摄多张对应的指纹照片，并选取上述多张对应的指纹照片中的一张轮廓最清晰的指纹照片作为最终的指纹照片，这样能有效地避免了若只针对每根手指拍摄一张对应的指纹照片，且该对应的指纹照片不清晰，对后续的图像匹配造成影响而导致屏幕解锁不灵敏的情况，另外，通过选取多张对应的指纹照片中的一张轮廓最清晰的指纹照片作为最终的指纹照片，将轮廓最清晰的指纹照片保存并用来与获取到的当前的指纹图像来匹配比对，也能加快图像匹配的速度，使得用户能快速解锁屏幕。并且，可以将左手的5个手指的指纹对应的指纹照片标记为左手特定指纹照片，将右手的5个手指的指纹对应的指纹照片标记为右手特定指纹照片。
进一步地，本申请一实施例中，步骤S2，包括：
S20：根据所述指纹图像中的指纹的朝向，判断所述指纹是否为左手手指的指纹。
S21：若是，将所述指纹图像与所述左手特定指纹照片进行匹配比对。
S22：若否，判定所述指纹为右手手指的指纹，将所述指纹图像与所述左手特定指纹照片进行匹配比对。
如上述步骤S20至S22所述，可以根据所述指纹图像中的指纹的朝向来确定所述指纹为左手手指的指纹或右手手指的指纹，若所述指纹图像中的指纹的朝向来确定所述指纹为左手手指的指纹，则将获取 到的用户当前的指纹图像与对应的本地保存的左手特定指纹照片进行匹配比对；而若所述指纹图像中的指纹的朝向来确定所述指纹为右手手指的指纹，则将获取到的用户当前的指纹图像与对应的本地保存的右手特定指纹照片进行匹配比对。通过所述指纹图像中的指纹的朝向来确定所述指纹为左手手指的指纹或右手手指的指纹，再选用本地保存对的对应特定指纹照片来匹配比对，有效地提高了图像匹配的速度，也使得用户能快速解锁屏幕。
进一步地，本申请一实施例中，步骤S2之后，包括：
S200：若匹配失败，获取在一定时间内的匹配失败次数。
S201：判断所述匹配失败次数是否大于预设次数。
S202：若是，锁定移动终端。
如上述步骤S200至S202所述，若在一定时间内，用户进行了多次解锁操作但仍未完成匹配解锁，即匹配失败，举例地，上述一定时间可设为1分钟，预先设置的预设次数为3次，假如在1分钟的时间内，用户进行了4次解锁操作但仍然未完成匹配解锁，即1分钟内的匹配失败次数为4，符合了匹配失败次数大于预设次数的条件，则可判定为出现了非法用户对屏幕进行解锁的情况，此时可以锁定移动终端，需要用户再重新触发进入解锁界面，或者需要延迟一段时间后才能够触发进入解锁界面。
进一步地，本申请一实施例中，步骤S202之后，包括：
S203：判断所述移动终端的SIM卡是否被更换。
S204：若是，向与所述移动终端预先绑定连接的第二移动终端发送丢失提醒信息。
如上述步骤S203和S204所述，持有移动终端的用户会预先设置一个紧急联系人，并将移动终端与该紧急联系人的第二移动终端进行绑定，当检测到所述移动终端被更换SIM卡后，则判定可能出现了用户的移动终端遭到了小偷的盗取，小偷把移动终端原来的SIM卡卸下并且换上新的SIM卡来防止用户拨打丢失了的移动终端的号码的情况，此时移动终端会向预先绑定连接的第二移动终端发送丢失提醒信息，即提醒该用户的移动终端可能出现了丢失的情况，并且会将更新后的号码同时发送给第二移动终端，使得用户能够得知小偷的号码，并可以通知警方，借助警方的帮助来寻找丢失的移动终端。
进一步地，本申请一实施例中，步骤S202之后，包括：
S205：开启移动数据业务。
S206：向与所述移动终端预先绑定连接的第二移动终端发送实时地理位置。
如上述步骤S205和S206所述，当检测到移动终端在被锁定之后，移动终端的移动数据业务会被启动，用户可以预先将自己的移动 终端与亲人或朋友的第二移动终端进行绑定连接。当出现非法用户进行屏幕解锁的时候，可能出现了移动终端丢失的情况，通过向与所述移动终端绑定连接的第二移动终端发送实时地理位置，便能清楚的获取到移动终端的当前位置，并根据上述实时地理位置能帮助用户对丢失的移动终端进行寻找，有效地提高了找回丢失的移动终端的概率。
进一步地，在本申请方案实施过程中，为了进一步提高解锁的速度，在收到解锁触发指令时，轮流开启前置摄像头和后置摄像头，并且迅速将前置摄像头和后置摄像头拍摄的图像内容进行分析；这部分拍摄内容仅在内存中存储，并且后续会删除以保证安全性；首先进行粗略判定，判定哪个摄像头的图像中存在类手指状图像，从而判定出开启哪个摄像头比较合适；并且在昏暗环境下，开启后摄像头的闪光灯，避免开启前摄像头闪光灯对用户眼睛造成的刺激；根据图像中的手指状图像位置，初步判断手指的焦距，并且迅速选择合适的摄像头和合适的聚焦距离，进行图像拍摄；由于拍摄角度，拍摄抖动等情况，拍摄的图像和原始存储图像并非百分百匹配，通过将拍摄的手指指纹图像，进行分区块处理，将手指指纹部分，划分为多个子区块，并且将子区块中，包含指纹中间部分的区块，与多个存储的指纹图像中的指纹中间部分进行对比，从而判定出具体拍摄的手指；以及选取进行对比的原始指纹图像；然后，将原始指纹图像也按照当前图像划分方式，划分为子区块，并分别进行子区块对比；当每个子区块的相似度，均超过阈值时(通常设置为90％)，则判定验证成功，完成解锁操作。本申请的屏幕解锁方法，通过在接收到解锁触发指令后，开启摄像头获取用户当前的指纹图像，再将用户当前的指纹图像与本地保存的指纹照片进行匹配比对，只有当所述获取到的用户当前的指纹图像与本地保存的指纹照片符合匹配要求时，才可以认定当前用户合法完成解锁。由于指纹具有唯一性、遗传性和不变性，每个人的指纹也是独一无二，如果获取的指纹图像内的指纹不是用户本人的指纹，则无法解锁移动终端，大大提高了屏幕解锁的安全性。
参照图2，本申请一实施例的屏幕解锁装置，应用于移动终端，所述装置包括：
第一获取模块1，用于接收解锁触发指令后，开启摄像头获取用户当前的指纹图像。
匹配模块2，用于将所述指纹图像与本地保存的指纹照片进行匹配比对。
解锁模块3，用于若匹配成功，将屏幕解锁。
在上述第一获取模块中，用户在需要解锁移动终端时，可通过触发相应按键，或者当检测到用户的指定操作(例如将手指靠近摄像头)来生成解锁触发指令，进而进入移动终端的解锁界面，此时摄像头会 启动，并用来获取用户当前的指纹图像。
在上述匹配模块中，本地保存有用户预先保存的指纹照片，本步骤需要将获取到的指纹图像与本地的指纹照片进行匹配比对，具体实现时，可以由用户在解锁界面上通过按钮触发来发出图像匹配指令，从而调用出预存于本地的指纹照片，来与当前获取到的指纹图像进行图像匹配，或者由用户通过按下移动终端的指定按键(例如音量增大键或音量减小键)来发出图像匹配指令，调用出预存于本地的指纹照片来与当前获取到的指纹图像，来与当前获取到的指纹图像进行图像匹配，本实施例不作具体限定。
在上述解锁模块中，只有当所述获取到的用户当前的指纹图像与本地保存的指纹照片符合匹配要求(符合匹配要求具体可为用户当前的指纹图像与本地保存的指纹照片的相似度大于某一预设阈值，例如90％)，才可以认定当前用户合法完成解锁。由于指纹具有唯一性、遗传性和不变性，尚未发现有不同的人拥有相同的指纹，所以每个人的指纹也是独一无二。因此，利用获取指纹图像，并将指纹图像与用户预先存储的指纹照片进行匹配比对，如果获取的指纹图像内的指纹不是用户本人的指纹，则无法解锁移动终端，提高了屏幕解锁的安全性。
进一步地，本申请一实施例中，所述装置还包括：

第一匹配单元，用于若所述指纹是左手手指的指纹，将所述指纹图像与所述左手特定指纹照片进行匹配比对。
第二匹配单元，用于若所述指纹不是左手手指的指纹，则判定所述指纹为右手手指的指纹，将所述指纹图像与所述左手特定指纹照片进行匹配比对。
本实施例中，可以根据所述指纹图像中的指纹的朝向来确定所述指纹为左手手指的指纹或右手手指的指纹，若所述指纹图像中的指纹的朝向来确定所述指纹为左手手指的指纹，则将获取到的用户当前的指纹图像与对应的本地保存的左手特定指纹照片进行匹配比对；而若所述指纹图像中的指纹的朝向来确定所述指纹为右手手指的指纹，则将获取到的用户当前的指纹图像与对应的本地保存的右手特定指纹照片进行匹配比对。通过所述指纹图像中的指纹的朝向来确定所述指纹为左手手指的指纹或右手手指的指纹，再选用本地保存对的对应特定指纹照片来匹配比对，有效地提高了图像匹配的速度，也使得用户能快速解锁屏幕。
进一步地，本申请一实施例中，所述装置还包括：
第二获取模块，用于若匹配失败，获取在一定时间内的匹配失败次数。
第一判断模块，用于判断所述匹配失败次数是否大于预设次数。
锁定模块，用于若所述匹配失败次数大于预设次数，锁定移动终端。
本实施例中，若在一定时间内，用户进行了多次解锁操作但仍未完成匹配解锁，即匹配失败，举例地，上述一定时间可设为1分钟，预先设置的预设次数为3次，假如在1分钟的时间内，用户进行了4次解锁操作但仍然未完成匹配解锁，即1分钟内的匹配失败次数为4，符合了匹配失败次数大于预设次数的条件，则可判定为出现了非法用户对屏幕进行解锁的情况，此时可以锁定移动终端，需要用户再重新触发进入解锁界面，或者需要延迟一段时间后才能够触发进入解锁界面。
进一步地，本申请一实施例中，所述装置还包括：
第二判断模块，用于判断所述移动终端的SIM卡是否被更换。

进一步地，在本申请方案实施过程中，为了进一步提高解锁的速度，在收到解锁触发指令时，轮流开启前置摄像头和后置摄像头，并且迅速将前置摄像头和后置摄像头拍摄的图像内容进行分析；这部分拍摄内容仅在内存中存储，并且后续会删除以保证安全性；首先进行粗略判定，判定哪个摄像头的图像中存在类手指状图像，从而判定出开启哪个摄像头比较合适；并且在昏暗环境下，开启后摄像头的闪光灯，避免开启前摄像头闪光灯对用户眼睛造成的刺激；根据图像中的手指状图像位置，初步判断手指的焦距，并且迅速选择合适的摄像头和合适的聚焦距离，进行图像拍摄；由于拍摄角度，拍摄抖动等情况，拍摄的图像和原始存储图像并非百分百匹配，通过将拍摄的手指指纹图像，进行分区块处理，将手指指纹部分，划分为多个子区块，并且将子区块中，包含指纹中间部分的区块，与多个存储的指纹图像中的指纹中间部分进行对比，从而判定出具体拍摄的手指；以及选取进行对比的原始指纹图像；然后，将原始指纹图像也按照当前图像划分方式，划分为子区块，并分别进行子区块对比；当每个子区块的相似度，均超过阈值时(通常设置为90％)，则判定验证成功，完成解锁操作。
本申请的屏幕解锁装置，通过在接收到解锁触发指令后，开启摄像头获取用户当前的指纹图像，再将用户当前的指纹图像与本地保存的指纹照片进行匹配比对，只有当所述获取到的用户当前的指纹图像 与本地保存的指纹照片符合匹配要求时，才可以认定当前用户合法完成解锁。由于指纹具有唯一性、遗传性和不变性，每个人的指纹也是独一无二，如果获取的指纹图像内的指纹不是用户本人的指纹，则无法解锁移动终端，大大提高了屏幕解锁的安全性。
