具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的主要解决方案是：通过在运行所述第一系统时，监测所述第一系统的运行界面是否获取到预设切换应用的操作指令；若所述第一系统的运行界面获取到预设切换应用的操作指令，则开启人脸检测用户身份功能；并在用户人脸检测通过时，开启指纹确认用户身份功能；然后在指纹确认用户身份通过时，执行系统切换操作，切换所述第一系统的运行界面至第二系统的运行界面，通过自动采集用户人脸及指纹，然后进行匹配，在人脸检测和指纹确认用户身份的双重确认之后，才进行系统切换，有效地保证了移动终端安全和用户个人隐私，并且不需要用户进行输入密码等繁琐操作，提高了用户体验，提高了切换效率。
本发明实施例考虑到，现有技术中，通过一键热启动切换、指纹切换、输入密码切换等方案进行系统切换，移动终端安全和个人隐私都不能得到有效的保护，用户的办公保密文件容易造成泄露；存在安全隐患，操作步骤繁琐，切换效率低。
为此，本发明提出一种双系统切换方法，通过在运行所述第一系统时，监测所述第一系统的运行界面是否获取到预设切换应用的操作指令；若所述第一系统的运行界面获取到预设切换应用的操作指令，则开启人脸检测用户身份功能；并在用户人脸检测通过时，开启指纹确认用户身份功能；然后在指纹确认用户身份通过时，执行系统切换操作，切换所述第一系统的运行界面至第二系统的运行界面，通过自动采集用户人脸及指纹，然后进行匹配，在人脸检测和指纹确认用户身份的双重确认之后，才进行系统切换，有效地保证了移动终端安全和用户个人隐私，并且不需要用户进行输入密码等繁琐操作，提高了用户体验，提高了切换效率。
参照图1，图1为本发明双系统切换方法第一实施例的流程示意图。
在本实施例中，该方法包括：
步骤S1000，在运行所述第一系统时，监测所述第一系统的运行界面是否获取到预设切换应用的操作指令；
在本实施例中，在移动终端运行第一系统时，监测所述第一系统的运行界面是否获取到预设切换应用的操作指令，所述预设切换应用的操作指令是输入预设切换应用的操作产生的指令。本实施例中的预设切换应用的操作可以包括预设手势、预设的快捷键或快捷按钮等。
步骤S2000，若所述第一系统的运行界面获取到预设切换应用的操作指令，则开启人脸检测用户身份功能；
当在所述第一系统的运行界面获取到预设切换应用的操作指令时，则开启人脸检测用户身份功能；即通过人脸识别检测用户的身份，具体通过采集用户的人脸图像，然后将采集到的用户的人脸图像与预存的人脸图像进行匹配，从而判断用户是否具备进行系统切换的权限。若在预存的人脸图像中匹配到一致的人脸图像，则说明当前用户具备进行系统切换的权限，若在预存的人脸图像中没有匹配到一致的人脸图像，则说明当前用户不具备进行系统切换的权限。其中，所述预存的人脸图像为预先采集具备进行系统切换的权限的用户的人脸图像，然后保存在移动终端或服务器中的人脸图像。
步骤S3000，在用户人脸检测通过时，开启指纹确认用户身份功能；
当在预存的人脸图像匹配到与采集到的人脸图像一致的人脸图像时，此时需要进一步通过指纹对当前用户进行验证，因此，此时首先需要开启指纹确认用户身份功能，即开启指纹采集模式，然后对用户的指纹信息进行采集，并将采集到的信息与预存的指纹信息进行匹配，从而确认用户身份，当所述用户指纹信息与预存的指纹信息进行匹配的相似度达到预设值时即可确定用户指纹确认用户身份通过。当所述用户指纹信息与预存的指纹信息进行匹配的相似度达不到预设值时，即可确定用户指纹确认用户身份不通过，所述预设值可以为用户根据移动终端中的文件的安全级别进行设置的值，比如当在移动终端中的保存的文件安全级别较高时，用户可以将所述预设值设置为百分之九十。当在移动终端中的保存的文件安全级别较低时，相对需要的安全级别较低，用户可以将所述预设值设置为百分之六十。
步骤S4000，在指纹确认用户身份通过时，执行系统切换操作，切换所述第一系统的运行界面至第二系统的运行界面。
在指纹确认用户身份通过时，即可执行系统切换操作，切换所述第一系统的运行界面至第二系统的运行界面。
本实施例提出的双系统切换方法，通过在运行所述第一系统时，监测所述第一系统的运行界面是否获取到预设切换应用的操作指令；若所述第一系统的运行界面获取到预设切换应用的操作指令，则开启人脸检测用户身份功能；并在用户人脸检测通过时，开启指纹确认用户身份功能；然后在指纹确认用户身份通过时，执行系统切换操作，切换所述第一系统的运行界面至第二系统的运行界面，通过自动采集用户人脸及指纹，然后进行匹配，在人脸检测和指纹确认用户身份的双重确认之后，才进行系统切换，有效地保证了移动终端安全和用户个人隐私，并且不需要用户进行输入密码等繁琐操作，提高了用户体验，提高了切换效率。
进一步地，参照图2，基于本发明双系统切换方法第一实施例提出本发明双系统切换方法第二实施例。
在本实施例中，所述步骤S2000包括：
步骤S2100，开启人脸识别功能，采集用户的脸部图像；
步骤S2200，将采集到的脸部图像与预存的脸部图像进行对比；
步骤S2300，若对比到与采集到的脸部图像相匹配的脸部图像，则确定用户人脸检测通过，否则，确定用户人脸检测不通过。
在本实施例中，通过移动终端的摄像头采集用户的脸部图像，在用户触发系统切换指令之后，移动终端根据接收到的系统切换指令开启人脸识别功能，即开启摄像头，然后摄像头即对用户的脸部图像进行采集，在采集到用户脸部图像之后，可以将采集到的脸部图像发送至移动终端后台服务器，通过后台服务器将采集到的脸部图像与存储器中预先保存的脸部图像进行对比，以判断存储器中预先保存的脸部图像中是否存在与采集到的脸部图像相匹配的脸部图像，其中，存储器中预先保存的脸部图像对应的用户为具备系统切换权限的用户；若对比到与采集到的脸部图像相匹配的脸部图像，则说明当前用户具备切换系统的权限，此时可以确定用户人脸检测通过，若没有对比到与采集到的脸部图像相匹配的脸部图像，则说明当前用户不具备切换系统的权限，确定用户人脸检测不通过，从而确保进行系统切换的用户都是具备切换权限的用户，保证了移动终端的安全及用户个人隐私不被泄露。
进一步地，参照图3，基于本发明双系统切换方法第二实施例提出本发明双系统切换方法第三实施例。
在本实施例中，所述步骤S2200包括：
步骤S2210，采用识别准确度大于第一阈值的人脸识别算法提取所述用户的脸部图像特征；
步骤S2220，根据所述用户的脸部图像特征和预存的脸部图像特征，分别计算所述用户的脸部图像和预存的脸部之间的相似度；
步骤S2230，检测所述用户的脸部图像和预存的脸部之间的相似度是否大于第二阈值；
步骤S2240，若所述相似度大于所述第二阈值，则确认所述相似度所对应的预存脸部对应用户为与所述用户相匹配的目标用户。
在本实施例中，识别准确度大于第一阈值的人脸识别算法具体可以为联合贝叶斯算法。在本发明实施例中，通过联合贝叶斯算法提取用户的脸部图像的图像特征，及预存的脸部图像特征，然后将提取到的用户的脸部图像的图像特征与预存的脸部图像特征进行匹配，分别计算用户的脸部图像和预存的脸部图像之间的相似度；然后检测计算得到用户的脸部图像和预存的脸部图像之间的相似度是否有超过第二阈值，若检测到预存的脸部图像中存在与用户的脸部图像的相似度大于第二阈值的脸部图像，则确认相似度大于第二阈值的预存脸部图像对应用户为与此时登记入住的用户相匹配的目标用户，从而保证触发系统切换指令的用户与预存用户之间的准确匹配，便可直接确认用户身份验证成功，无需通过手动验证用户的身份，从而减少用户操作。
本实施例提出的双系统切换方法，首先通过采用识别准确度大于第一阈值的人脸识别算法提取所述用户的脸部图像特征；然后根据所述用户的脸部图像特征和预存的脸部图像特征，分别计算所述用户的脸部图像和预存的脸部图像之间的相似度；再检测所述用户的脸部图像和预存的脸部图像之间的相似度是否大于第二阈值；若所述相似度大于所述第二阈值，则确认所述相似度所对应的预存脸部图像对应用户为与所述用户相匹配的目标用户，无需通过手动验证用户的身份，从而减少用户操作、简化验证流程、提高验证效率。
进一步地，参照图4，基于本发明双系统切换方法第三实施例提出本发明双系统切换方法第四实施例。
在本实施例中，所述步骤S2210包括：
步骤S2211，对所述用户的脸部图像进行特征点定位；
步骤S2212，根据特征点定位结果将所述用户的脸部图像分割成若干个人脸区域；
步骤S2213，采用所述人脸区域对应的深度网络对所述人脸区域进行特征提取；
步骤S2214，将从各个人脸区域提取的特征进行重组，得到所述签到用户的人脸图像的图像特征。
在本实施例中，首先对用户的脸部图像进行特征点定位，根据特征点定位结果将用户的脸部图像分割成若干个人脸区域，对于每一个人脸区域，采用该人脸区域对应的深度网络对该人脸区域进行特征提取，然后将从各个人脸区域提取的特征进行重组，即可得到签到用户的人脸图像的图像特征。人脸图像中的特征点是指人脸中诸如双眼的中心、鼻尖、两侧嘴角之类的特征点。特征点定位结果可采用特征点向量进行表示，特征点向量中包括各个特征点的坐标。对于各个不同的人脸区域，预先分别训练相应的深度网络。深度网络用于从人脸区域中提取图像特征，深度网络可采用深度卷积神经网络Convolutional Neural Networks ， CNNs) 。在本发明实施例中，采用基于深度学习的人脸识别算法获取人脸图像的图像特征，相较于其它人脸识别算法，识别准确度更高。另外，针对不同的人脸区域(如眼部区域、鼻子区域、嘴部区域等) ，分别训练各自对应的深度网络，并采用各自对应的深度网络进行特征提取，充分确保特征提取的准确度。
本实施例提出的双系统切换方法，首先对所述用户的脸部图像进行特征点定位；然后根据特征点定位结果将所述用户的脸部图像分割成若干个人脸区域；再采用所述人脸区域对应的深度网络对所述人脸区域进行特征提取；将从各个人脸区域提取的特征进行重组，即可得到所述签到用户的人脸图像的图像特征，确保了特征提取的准确度。
进一步地，参照图5，基于本发明双系统切换方法第一实施例提出本发明双系统切换方法第五实施例。
在本实施例中，所述步骤S3000包括：
步骤S3100，开启指纹采集模式，获取用户手指指纹特征信息；
步骤S3200，将所述用户手指指纹特征信息与预存的指纹信息进行匹配；
步骤S3300，若对比到与采集到的用户手指指纹特征信息相匹配的指纹信息，则确定用户指纹确认用户身份通过，否则，确定用户指纹确认用户身份不通过。
在本实施例中，在用户人脸检测通过之后，需要进一步进行指纹确认。具体地，在用户人脸检测通过之后，开启指纹采集模式，其中，指纹识别区域可以为移动终端的返回键区域、移动终端后背区域、移动终端的屏幕等区域，通过指纹识别区域接收用户的手指感应，识别并采集用户的指纹特征信息。当移动终端感测到用户手指输入触摸时，对用户的指纹特征信息进行识别并采集。所述指纹特征信息是指指纹特征点提供的指纹唯一性的特征信息。由于人的手指纹路不是连续、平滑笔直的，因此经常出现中断、分叉或转折。所述特征点就是指人的手指纹路出现中断、分叉或转折时，出现中断、分叉和转折的点。
然后将所述用户手指指纹特征信息与预存的指纹信息进行匹配，当所述用户指纹特征信息与预存的指纹信息进行匹配的相似度达到预设值时即可确定用户指纹确认用户身份通过。当所述用户指纹特征信息与预存的指纹信息进行匹配的相似度达不到预设值时，即可确定用户指纹确认用户身份不通过，所述预设值可以为用户根据移动终端中的文件的安全级别进行设置的值，比如当在移动终端中的保存的文件安全级别较高时，用户可以将所述预设值设置为百分之九十。当在移动终端中的保存的文件安全级别较低时，相对需要的安全级别较低，用户可以将所述预设值设置为百分之六十。
本实施例提出的双系统切换方法，通过开启指纹采集模式，获取用户手指指纹特征信息；然后将所述用户手指指纹特征信息与预存的指纹信息进行匹配；若对比到与采集到的用户手指指纹特征信息相匹配的指纹信息，则确定用户指纹确认用户身份通过，否则，确定用户指纹确认用户身份不通过，进一步确认用户身份，确保移动终端及用户隐私安全。
进一步地，参照图6，基于本发明双系统切换方法第五实施例提出本发明双系统切换方法第六实施例。
在本实施例中，所述步骤S3200之前的步骤，还包括：
步骤S3400，对所述用户手指指纹特征信息图像进行高反差处理，获得高反差处理后的用户手指指纹特征信息图像；
步骤S3500，对高反差处理后的用户手指指纹特征信息图像进行压缩处理，获得压缩处理后的用户手指指纹特征信息图像。
在本实施例中，在获取用户手指指纹特征信息图像之后，首先对所述用户手指指纹特征信息图像进行高反差处理。具体地，对所述用户手指指纹特征信息图像进行高反差处理的方式可以为：首先根据用户触发的计算指令计算所述用户手指指纹特征信息图像像素点的颜色值；然后对所述用户手指指纹特征信息图像进行高斯滤波，计算进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值；将用户手指指纹特征信息图像像素点的颜色值与进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值相减，再加上预设值，得到所述高反差处理图像对应像素点的颜色值，从而获得进行高反差处理后的图像。
获得高反差处理后的用户手指指纹特征信息图像之后，需要对所述高反差处理后的用户手指指纹特征信息图像进行压缩。具体地，首先根据用户触发的处理指令对所述进行锐化处理后的用户手指指纹特征信息图像进行离散余弦变换处理；对进行离散余弦变换处理之后的用户手指指纹特征信息图像进行量化处理；对进行量化之后的用户手指指纹特征信息图像进行编码，获得编码后的图像块；对编码后的图像块进行解码，获得解码后的图像块；将所述解码后的图像块进行图像重建，获得压缩的图像。
本实施例提出的双系统切换方法，通过对所述用户手指指纹特征信息图像进行高反差处理，获得高反差处理后的用户手指指纹特征信息图像；然后对高反差处理后的用户手指指纹特征信息图像进行压缩处理，获得压缩处理后的用户手指指纹特征信息图像。改善了图像的锐化效果，减少了保存图像所需的内存。
进一步地，参照图7，基于本发明双系统切换方法第六实施例提出本发明双系统切换方法第七实施例。
在本实施例中，所述步骤S3400包括：

步骤S3420，对所述用户手指指纹特征信息图像进行高斯滤波，计算进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值；
步骤S3430，将用户手指指纹特征信息图像像素点的颜色值与进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值相减，再加上预设值，得到所述高反差处理图像对应像素点的颜色值，从而获得进行高反差处理后的图像。
在本实施例中，在本实施例中，首先用户触发计算指令，移动终端接收所述计算指令，并根据所述计算指令计算用户手指指纹特征信息图像像素点的颜色值。然后用户触发处理指令，移动终端根据所述处理指令对所述用户手指指纹特征信息图像进行高斯滤波，具体地，用预设的模板所述扫描用户手指指纹特征信息图像中的每一个像素，用模板确定的邻域内像素的加权平均灰度值去替代模板中心像素点的值。所述高斯滤波可以采用离散化窗口滑窗卷积进行，具体实施过程中还可以采用傅里叶变换进行。然后根据用户触发的计算指令计算进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值。再将所述用户手指指纹特征信息图像像素点的颜色值与进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值相减，再加上预设值，得到所述高反差处理图像对应像素点的颜色值，从而获得进行高反差处理后的图像。所述预设值为128，也可以为126、128等值。
本实施例通过根据用户触发的计算指令计算所述用户手指指纹特征信息图像像素点的颜色值；对所述用户手指指纹特征信息图像进行高斯滤波，计算进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值；将用户手指指纹特征信息图像像素点的颜色值与进行高斯滤波后的用户手指指纹特征信息图像像素点的颜色值相减，再加上128，得到所述高反差处理图像对应像素点的颜色值，从而获得进行高反差处理后的图像。通过上述方式，可以获得进行高反差处理后的用户手指指纹特征信息图像，使得所述用户手指指纹特征信息图像更清晰，以使图像呈现较佳视觉效果。
