目前，启动应用的方式通常是点击应用的图标即可启动应用，在启动应用之后，在该应用的应用界面可显示该应用的所有信息，这样会影响应用的安全性。而在本申请实施例中，如果用户在指纹采集区域内输入正确的指纹和正确的滑动轨迹，则启动该指纹对应的应用并设置该应用的运行模式为私密模式；如果用户在指纹采集区域内仅输入正确的指纹，则启动该指纹对应的应用并设置该应用的运行模式为普通模式。实现了只有在特定条件下才触发应用的私密模式，提升了应用的安全性。
在本申请的一实现方式中，所述检测到手指针对所述指纹采集区域的滑动操作之前，所述方法还包括：
所述处理器控制所述指纹采集区域显示所述目标应用的图标；
所述检测到手指针对所述指纹采集区域的滑动操作，包括：检测到手指拖动所述目标应用的图标在所述指纹采集区域内滑动的滑动操作。
可选地，为了避免因图标影响采集到的指纹图像的质量，在拖动所述目标应用的图标在所述指纹采集区域内滑动的过程中，将所述目标应用的图标进行透明化处理，进行透明化处理后的所述目标应用的图标除边框之外所有地方均为透明的，所述边框的颜色为预设颜色，所述预设颜色为浅色，例如白色、灰色等。
其中，在拖动所述目标应用的图标在所述指纹采集区域内滑动的过程中指的是在拖动所述目标应用的图标在所述指纹采集区域内滑动的起始点时，也可以是起始点之后的某一个时刻，在此不作限定。
可选地，在滑动操作结束后，对所述目标应用的图标进行恢复操作。
可选地，所述检测到手指针对所述指纹采集区域的按压操作，包括：检测到手指针对所述目标应用的图标的按压操作。

其中，目标应有的应用界面例如是目标应用的主界面、目标应用的设置界面、目标应用的某个功能的界面等等。特定触控操作例如是长按操作、按照特定方向滑动的滑动操作、按照特定轨迹滑动的滑动操作等。
可以看出，在本申请实施例中，虽然在刚开始启动应用时，没有启动该应用的私密模式，后续如果用户在该应用的应用界面进行设定的触控操作是可以触发该应用的私密模式，无需用户按照特定的启动方式再次启动该应用，提升了触发私密模式的灵活性。
在本申请的一实现方式中，所述将所述目标应用的运行模式设置为私密模式之后，所述方法还包括：
在检测到应用状态切换指令时，所述处理器将所述目标应用的应用状态从前台应用状态切换至后台应用状态，以及记录当前时刻为第一时刻；

在所述第一时刻与当前时刻的差值大于或等于第一阈值时，所述处理器将所述目标应用的运行模式从所述私密模式切换至所述普通模式；
在所述第一时刻与当前时刻的差值小于所述第一阈值时，所述处理器维持所述目标应用的运行模式。
其中，应用状态切换指令例如可以是点击HOME键触发的，也可以是点击推送消息触发的等。
其中，处理器将目标应用的应用状态从前台应用状态切换至后台应用状态后，处理器直接将目标应用的应用界面退出前台显示。处理器将目标应用的应用状态从后台应用状态切换至前台应用状态后，处理器直接将目标应用的应用界面在前台显示。
其中，针对目标应用的图标的点击操作可以是针对在主界面上显示的目标应用的图标的点击操作，也可以是针对在其他应用的应用界面上显示的目标应用的图标的点击操作等。
可以看出，在本申请实施例中，在第一时刻，将目标应用的应用界面退出前台显示，下次目标应用再次进入前台显示时，如果第一时刻与当前时刻的时间间隔较长，则将目标应用的运行模式切换至普通模式，否则，维持目标应用在私密模式，这样避免了其他用户在该时间间隔使用移动终端而导致信息泄露的问题，进一步提升了应用的安全性。
在本申请的一实现方式中，所述将所述目标应用的运行模式设置为私密模式之后，所述方法还包括：
在检测到应用退出指令时，所述处理器退出所述目标应用，以及记录当前时刻为第二时刻；
在检测到针对所述目标应用的图标的点击操作时，所述处理器启动所述目标应用；

在所述第二时刻与当前时刻的差值小于所述第二阈值时，所述处理器将所述目标应用的运行模式设置为所述私密模式。
其中，针对目标应用的图标的点击操作可以是针对在主界面上显示的目标应用的图标的点击操作，也可以是针对在其他应用的应用界面上显示的目标应用的图标的点击操作等。
可以看出，在本申请实施例中，在第二时刻，退出目标应用，下次再次启动目标应用示时，如果第二时刻与当前时刻的时间间隔较短，则在启动目标应用后，将目标应用的运行模式设置为私密模式，否则，在启动目标应用后，将目标应用的运行模式设置为普通模 式，无需用户按照特定的启动方式再次启动该应用，提升了触发私密模式的灵活性。
