具体实施方式
本申请的说明书以及附图中的术语“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。此外，本申请的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
目前，电子设备的解锁方式大多包括生物特征解锁。其中，生物特征解锁包括但不限于指纹解锁、人脸解锁、语音解锁等，具有方便、快捷等特点。然而，生物特征解锁存在一定的安全隐患。例如，在用户无意识(如睡眠)的状态下，用户的指纹特征、人脸特征、声音特征等可能被其他人用来解锁手机等电子设备。如图1所示，用户的电子设备设置为人脸解锁。在用户休息的过程中，其他用户通过电子设备采集该用户的人脸图像。如此，电子设备确定人脸匹配正确之后，人脸解锁成功，电子设备不再处于锁屏状态。其他用户即可浏览该电子设备中的信息，导致电子设备内部信息泄露。
在相关技术中，电子设备还能够为用户提供锁定模式。例如，用户在安全锁定设置中，打开“在关机界面使用锁定模式”选项。用户长按关机键，显示开关机界面，且在开关机 界面中显示“锁定模式”，点击“锁定模式”之后，电子设备进入锁定模式。此种情况下，用户只能使用密码解锁屏幕，生物特征解锁功能失效。在密码解锁屏幕之后，电子设备退出锁定模式。即使再次锁屏，生物特征解锁功能仍有效。如果电子设备需要再次进入锁定模式，用户就需再次长按关机键，重新点击“锁定模式”。
也就是说，用户执行触发操作，才能使电子设备进入锁定模式，处理步骤复杂，操作繁琐。并且，电子设备每次进入锁定模式，均需用户在开关机界面进行操作。在用户遗忘执行上述操作的情况下，电子设备的生物特征解锁功能仍有效，也就存在信息泄露的风险。
为了解决上述技术问题，本申请实施例提供一种信息保护方法，该方法的技术构思在于：电子设备接收第一信息，之后，根据第一信息，确定生物特征解锁屏幕的功能失效。其中，第一信息包括以下至少一项：第一指令、第一时间信息、或第一状态信息。第一指令指示关闭生物特征解锁屏幕的功能，第一时间信息指示当前时间，第一状态信息指示用户所处的状态。这样一来，电子设备即可在接收第一信息之后，响应于第一指令，或根据第一时间信息指示的时间，或根据用户所处的状态，来确定生物特征解锁屏幕的功能失效，以避免用户的生物特征信息丢失所导致的信息泄露问题。
本申请实施例提供的屏幕锁屏方法适用于电子设备，且该电子设备至少包括一个触摸屏。示例性的，该电子设备具体可以是手机、平板电脑、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、上网本、个人数字助理(personal digital assistant，PDA)等，本申请实施例对电子设备的具体类型不作任何限制。

无线通信模块160可以提供应用在电子设备100上的包括无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，蓝牙(Bluetooth，BT)，全球导航卫星系统(global navigation satellite system，GNSS)，调频(frequency modulation， FM)，近距离无线通信技术(near field communication，NFC)，红外技术(infrared，IR)等无线通信的解决方案。无线通信模块160可以是集成一个或多个通信处理模块的一个或多个器件。无线通信模块160经由天线2接收电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块160还可以从处理器110接收待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。
在一些实施例中，电子设备100的天线1和移动通信模块150耦合，天线2和无线通信模块160耦合，使得电子设备100可以通过无线通信技术与网络以及其他设备通信。所述无线通信技术可以包括全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)，码分多址接入(code division multiple access，CDMA)，宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)，BT，GNSS，WLAN，NFC，FM，和/或IR技术等。所述GNSS可以包括全球卫星定位系统(global positioning system，GPS)，全球导航卫星系统(global navigation satellite system，GLONASS)，北斗卫星导航系统(beidou navigation satellite system，BDS)，准天顶卫星系统(quasi-zenith satellite system，QZSS)和/或星基增强系统(satellite based augmentation systems，SBAS)。

为了便于理解，以下结合附图对本申请实施例提供的一种屏幕锁屏方法进行具体介绍。以下实施例中均以手机作为电子设备100举例说明。

示例三，第一界面上的预设次数的点击操作。其中，第一界面的介绍参见示例一的相关说明，此处不再赘述。示例性的，用户在第一界面上连续执行三次点击操作。相应的，电子设备检测到第一界面上的连续三次点击操作，即接收到第一指令。其中，预设次数，也可以是两次、或四次，或其他数值，本申请实施例对此不作限定。以图4d为例，在锁屏界面401中，用户连续敲击三次触摸屏，电子设备即可接收到第一指令。
示例四，第一指令包括第一语音指令。示例性的，用户说出“关闭生物特征解锁屏幕的功能”的语句。相应的，电子设备检测用户发出的语音消息，且识别到“关闭生物特征解锁屏幕的功能”的语义时，表征电子设备接收到第一语音指令。例如，以图4e为例，用户靠近电子设备的麦克风位置，说出“关闭生物特征解锁屏幕的功能”的语句，电子设备通过麦克风检测到第一语音指令。
示例五，第一指令包括以下至少一项：在密码输入界面中，按住至少一个密码键的时间超过预设时长，或按压至少一个密码键的力度超过预设力度，或在至少一个密码键的周围画圈。例如，当输入到密码键“3”时，按住键盘上的“3”的时间超过预设时长。或如图4f所示，在键盘上的“3”的周围画一个圈。本申请实施例对预设时长和预设力度不作限定，例如预设时长可以是1秒，预设力度可以是1500帕斯卡。
示例六，第一指令包括以下至少一项：按住任一手势节点的时间超过预设时长，或按压任一手势节点的力度超过预设力度，或在任一手势节点的周围画圈。其中，手势节点是指手势图形的某个节点。例如，在画到最后一个节点时，按住最后一个节点超过预设时长，或如图4g所示，在最后一个节点的周围画一个圈。本申请实施例对预设时长和预设力度不作限定，例如预设时长可以是1秒，预设力度可以是1500帕斯卡。
应理解，上述仅给出了第一指令的六个示例，即用户在第一界面执行操作，或说出“关闭生物特征解锁屏幕的功能”语音消息即可，简化了用户的处理过程，且能够使得电子设备准确地接收到第一指令。当然，第一指令还可以有其他实现方式，本申请对此不作限定。
需要说明的是，第一指令，也可以指示：解锁屏幕的方式为密码解锁，不包括其他的屏幕解方式，如生物特征解锁屏幕。此种情况下，用户采用密码解锁屏幕才有效，其他的解锁方式均无效。
第二项、第一时间信息。其中，第一时间信息为当前的时间信息，即电子设备所记录的当前时刻点的信息。例如，仍以图4d为例，电子设备显示当前时刻点为08点08分，则第一时间信息为08点08分。
第三项、第一状态信息。其中，第一状态信息指示用户所处的状态，如第一状态信息指示用户处于睡眠状态。
作为一种可能的实现方式，智能穿戴设备向电子设备发送第一状态信息。相应的，电子设备接收来自智能穿戴设备的第一状态信息。其中，第一状态信息指示用户处于睡眠状态。智能穿戴设备可以是智能手环、智能手表、智能眼镜、智能眼镜按摩仪等。例如，以智能手环为例，参见图4h，智能手环采集用户的脉搏信息，基于采集的脉搏信息确定用户处于睡眠状态，生成第一状态信息之后，向电子设备提供第一状态信息。电子设备通过收发器即可接收到第一状态信息。再如，以智能眼镜为例，参见图4i，智能眼镜采集用户的眼球运动信息，基于采集的眼球运动信息确定用户处于睡眠状态，生成第一状态信息之后，向电子设备提供第一状态信息。电子设备通过收发器即可接收到第一状态信息。
应理解，上述仅给出了智能穿戴设备的两个示例，即智能手环、智能眼镜，以实时监控用户的状态，且向电子设备提供第一状态信息，以简化用户的处理过程。当然，智能穿戴设备还可以有其他实现方式，本申请对此不作限定。并且，电子设备的收发器也可以不接收第一状态信息。在智能穿戴设备实现为智能手环的情况下，电子设备的收发器接收用户的脉搏信息，电子设备的处理器基于接收到的脉搏信息确定用户处于睡眠状态，生成第一状态信息。或者，在智能穿戴设备实现为智能眼镜的情况下，电子设备的收发器接收用户的眼球运动信息，电子设备的处理器基于接收到的眼球运动信息确定用户处于睡眠状态，生成第一状态信息，以使电子设备基于第一状态信息执行S302。
需要说明的是，作为再一种可能的实现方式，电子设备上安装有声音传感器，声音传感器采集用户呼吸声音信息，电子设备内的处理器基于采集的呼吸声音信息确定用户处于睡眠状态，生成第一状态信息，以使电子设备基于第一状态信息执行S302。其中，上述声音传感器可以替换为麦克风，具体可以参见图2的介绍，此处不再赘述。
作为又一种可能的实现方式，智能家居设备向电子设备发送第一状态信息。相应的，电子设备接收来自智能家居设备的第一状态信息。其中，智能家居设备可以是智能枕等。例如，以智能枕为例，参见图4j，在用户休息过程中，用户的头部重力作用于智能枕。智能枕采集压力信息和持续时间，基于采集的压力信息和持续时间确定用户处于睡眠状态，生成第一状态信息之后，向电子设备提供第一状态信息。电子设备通过收发器即可接收到第一状态信息。
应理解，电子设备的收发器也可以不接收第一状态信息。在智能家居设备实现为智能枕的情况下，电子设备的收发器接收压力信息和持续时间信息，电子设备的处理器基于接收的压力信息和持续时间信息确定用户处于睡眠状态，生成第一状态信息，以基于第一状态信息执行S302。
需要说明的是，上述智能穿戴设备和智能家居设备可以包括支持无线通信技术的装置或芯片。其中，无线通信技术可以例如但不限于如下介绍：NFC技术、红外技术、GSM、GPRS、CDMA、WCDMA、TD-SCDMA、LTE、BT、GNSS、或FM等。
S302、电子设备根据第一信息，确定生物特征解锁屏幕的功能失效。
其中，S302的实现过程可以通过如下三个示例进行介绍：
示例1，在第一信息实现为上述第一项的情况下，即第一信息包括第一指令，电子设备响应于第一指令，确定生物特征解锁屏幕的功能失效。
示例2，在第一信息实现为上述第二项的情况下，即第一信息包括第一时间信息，电子设备将第一时间信息指示的时间与目标时间段进行比较，若第一时间信息指示的时间在目标时间段内，则电子设备确定生物特征解锁屏幕的功能失效。反之，若第一时间信息指示的时间在目标时间段外，则电子设备确定生物特征解锁屏幕的功能有效。例如，目标时间段为晚23点至次日早07点。若第一时间信息指示的时间为01点20分，则第一时间信息指示的时间在目标时间段内，电子设备确定生物特征解锁屏幕的功能失效。若第一时间信息指示的时间为07点20分，则第一时间信息指示的时间在目标时间段外，电子设备确定生物特征解锁屏幕的功能有效。
在一些实施例中，上述目标时间段可以是电子设备预配置的时间段，也可以是用户根据自身需求设置的时间段。例如，电子设备接收时间调整信息，其中，时间调整信息指示目标时间段。以图5为例，用户输入的时间调整信息中，目标时间段的起始时刻为23:30，目标时间段的结束时刻为07:00。也就是说，目标时间段从“晚23点至次日早07点”，调整为“晚23点半至次日早07点”，以方便用户根据自身实际状态，来调整目标时间段。
示例3，在第一信息实现为上述第三项的情况下，即第一信息包括第一状态信息，电子设备确定用户所处的状态为睡眠状态，即用户处于无意识状态，为了避免电子设备内的信息泄露，电子设备确定生物特征解锁屏幕的功能失效。
在一些实施例中，电子设备确定生物特征解锁屏幕的功能失效之后，电子设备的显示状态介绍如下：
电子设备的屏幕上可以显示以下至少一项：
第一项，提示信息。其中，提示信息指示采用密码解锁屏幕。示例性的，提示信息可以如图6中的(a)所示，即404所显示：请采用密码解锁。或者，提示信息可以如图6中的(b)所示，即404所显示：生物特征解锁功能失效，请使用密码解锁。
第二项，显示密码输入界面。其中，密码输入界面用于接收解锁屏幕的密码，如图6中的(c)所示，即显示密码输入界面405。由于电子设备显示的界面为密码输入界面，即用户对电子设备的任何应用进行处理之前，需在输入框内输入解锁屏幕的密码，才能进行处理。用户在有意识的状态才能够输入密码，也就能够避免用户在无意识状态下信息泄露的问题。
应理解，在一些实施例中，电子设备确定生物特征解锁屏幕的功能失效之后，且生物特征解锁屏幕的功能恢复之前，电子设备的屏幕仍正常显示，仅在接收到生物特征信息之后，显示上述提示信息和密码输入界面中的至少一项。如图6中的(d)所示，用户按压指纹识别按键，电子设备接收到用户的指纹信息，由于电子设备确定生物特征解锁屏幕的功能失效，且未恢复，由于电子设备无法确定是用户自主的行为，还是用户的生物特征被盗用，电子设备的显示状态如图6中的(a)、(b)、或(c)所示，以提示用户输入密码，且防止了电子设备内的信息泄露。
在一些实施例中，电子设备确定生物特征解锁屏幕的功能失效之后，生物特征解锁屏幕的功能恢复介绍如下：
示例一，电子设备设置一段预设时长，即自生物特征解锁屏幕的功能失效的时刻点为起始点的一段预设时长之后，电子设备确定生物特征解锁屏幕的功能恢复。
例如，用户在临时休息之前，按压锁屏界面上的开关控件，电子设备检测到第一指令 之后，即可确定一定时长，如30分钟之内，电子设备确定生物特征解锁屏幕的功能失效。在30分钟之后，电子设备确定生物特征解锁屏幕的功能恢复，以避免用户在临时休息过程中电子设备的信息被泄露的可能性，又能够简化用户操作，方便用户在有意识状态下能够快捷地解锁屏幕。
示例二，若电子设备检测到用户输入的密码，且与电子设备预存储的屏幕解锁密码一致，则屏幕解锁成功。也就是说，用户能够采用密码解锁屏幕，即电子设备将密码解锁屏幕成功，作为确定用户处于有意识状态的判断标准，所以，电子设备确定生物特征解锁屏幕的功能恢复，以使得用户能够再次快捷、方便地解锁屏幕。
示例性的，如图7a所示，电子设备锁屏之后，用户点击锁屏界面中的开关控件。相应的，电子设备检测到开关控件上的点击操作，即接收到第一指令，如图4a的说明。电子设备确定生物特征解锁功能失效。此种情况下，若其他用户采用生物特征解锁屏幕的方式来解锁屏幕，则电子设备接收生物特征信息(如指纹信息、人脸图像)之后，电子设备拒绝验证生物特征信息，提示用户密码解锁，具体参见图6的说明。若用户采用密码解锁屏幕，则电子设备接收解锁屏幕的密码之后，电子设备执行密码解锁过程。在密码解锁成功之后，电子设备确定生物特征解锁屏幕的功能恢复，以使得用户能够再次快捷、方便地解锁屏幕。
需要说明的是，屏幕解锁密码包括以下至少一项：数字、字母、符号、或预设手势。例如，屏幕解锁密码是6位数字、字母或符号的任意组合，如屏幕解锁密码为“123456”、“123abc”、“abcdef”、“123ab！”等。屏幕解锁密码可以如图4f所示的“7”字型滑动手势，当然，也可以是其他滑动手势，本申请实施例对此不作限定。
应理解，电子设备采用密码解锁屏幕之后，生物特征解锁屏幕的功能恢复，可以适用于S301中的任何一种情况(如第一信息包括第一指令、第一时间信息、第一状态信息)。
示例三，在第一信息实现为第一时间信息的情况下，若第一时间信息指示的时间在目标时间段外，则电子设备确定生物特征解锁屏幕的功能恢复。例如，仍以目标时间段为晚23点至次日早07点。若第一时间信息指示的时间为07点01分，则第一时间信息指示的时间在目标时间段外，即用户不在处于休息状态，电子设备确定生物特征解锁屏幕的功能恢复，以使用户方便、快捷地解锁屏幕。
示例性的，如图7b所示，电子设备锁屏之后，电子设备确定生物特征解锁功能失效，具体可以参见图7a的介绍。此种情况下，若其他用户采用生物特征解锁屏幕的方式来解锁屏幕，则电子设备接收生物特征信息(如指纹信息、人脸图像)，电子设备判断当前时间是否在目标时间段内，若是，则电子设备拒绝验证生物特征信息，提示用户密码解锁，具体参见图6的说明。若否，则电子设备执行密码解锁过程。在密码解锁成功之后，电子设备确定生物特征解锁屏幕的功能恢复，以使得用户能够再次快捷、方便地解锁屏幕。
在一些实施例中，在第一信息实现为第一状态信息的情况下，若第一状态信息指示用户处于睡眠状态，则电子设备确定生物特征解锁屏幕的功能失效。此种情况下，若其他用户采用生物特征解锁屏幕的方式来解锁屏幕，则电子设备接收生物特征信息(如指纹信息、人脸图像)，电子设备拒绝验证生物特征信息，提示用户密码解锁，具体参见图6的说明。若用户采用密码解锁屏幕，则电子设备接收解锁屏幕的密码之后，电子设备执行密码解锁过程。在密码解锁成功之后，电子设备确定生物特征解锁屏幕的功能恢复，以使得用户能够再次快捷、方便地解锁屏幕，如图7c所示。
需要说明的是，在本申请实施例中，生物特征解锁屏幕的功能失效之后，该功能恢复的方式可以参见上述图7a、图7b和图7c的介绍。本申请实施例中，生物特征解锁屏幕的功能无法通过设置的方式来恢复。也就是说，除上述图7a、图7b和图7c示出的方式之外，电子设备未设置其他用于恢复生物特征解锁屏幕功能的操作，具体说明如下：
例如，用户点击开关控件(具体可以参见图4a、图4b和图4c的介绍)之后，电子设备关闭生物特征解锁屏幕的功能。本申请实施例中，开关控件是单向的，也就是说，电子设备检测到开关控件上的点击操作或按压操作之后，仅能够确定生物特征解锁屏幕的功能失效，不具备恢复生物特征解锁屏幕的功能。即使用户再次点击开关控件，电子设备仍确定生物特征解锁屏幕的功能失效，而非生物特征解锁屏幕的功能恢复。生物特征解锁屏幕的功能恢复方式可以参见密码解锁屏幕的介绍。
再如，用户在第一界面上执行预设次数的点击操作(具体可以参见图4d的介绍)之后，电子设备关闭生物特征解锁屏幕的功能。即使用户再次在第一界面上执行一定次数的点击操作，电子设备仍确定生物特征解锁屏幕的功能失效，而非生物特征解锁屏幕的功能恢复。类似的，电子设备接收到第一语音指令(具体可以参见图4e的介绍)之后，电子设备关闭生物特征解锁屏幕的功能。即使用户说出“生物特征解锁屏幕的功能恢复”的语句。相应的，电子设备检测用户发出的语音消息，且识别到“生物特征解锁屏幕的功能恢复”的语义时，电子设备仍确定生物特征解锁屏幕的功能失效，而非生物特征解锁屏幕的功能恢复，以防止恶意用户通过声音模仿的方式，来恢复生物特征解锁屏幕的功能，降低了电子设备内信息泄露的风险。在第一指令实现为图4f或图4g的情况下，电子设备在密码输入界面未设置恢复生物特征解锁屏幕功能的操作，以避免恶意用户在密码输入界面执行操作，导致生物特征解锁屏幕功能被恶意用户恢复的现象。
又如，在第一执行实现为第一状态信息的情况下，电子设备根据第一状态信息，确定用户处于睡眠状态，则关闭生物特征解锁屏幕的功能。即使电子设备接收到第二状态信息，其中，第二状态信息指示的状态为：非睡眠状态，电子设备仍确定生物特征解锁屏幕的功能失效，而非生物特征解锁屏幕的功能恢复，以防止用户在睡眠过程中，智能穿戴设备被取走，且用于监测恶意用户的体征状态。此种情况下，智能穿戴设备所监测到的状态信息是恶意用户的状态信息，而非电子设备的真正使用者的信息。若恶意用户未处于睡眠状态，则智能穿戴设备向电子设备发送第二状态信息，即使电子设备接收到第二状态信息，电子设备仍确定生物特征解锁屏幕的功能失效，以防止生物特征解锁屏幕功能被恶意用户恢复，降低了电子设备内信息被泄露的风险。
本申请实施例公开了一种芯片系统，如图8所示，该芯片系统包括至少一个处理器801和至少一个接口电路802。处理器801和接口电路802可通过线路互联。例如，接口电路802可用于从其它装置(例如存储器)接收信号。又例如，接口电路802可用于向其它装置(例如处理器801)发送信号。示例性的，接口电路802可读取存储器中存储的指令，并将该指令发送给处理器801。当所述指令被处理器801执行时，可使得电子设备执行上述实施例中的各个步骤。当然，该芯片系统还可以包含其他分立器件，本申请实施例对此不作具体限定。

示例性的，上述处理器902具体可以为图2所示的处理器110，上述存储器903具体可以为图2所示的内部存储器121和/或外部存储器120，上述显示屏907具体可以为图2所示的显示屏194，上述触敏表面906具体可以为图2所示的传感器模块180中的触摸传感器，本申请实施例对此不做任何限制。
通过以上的实施方式的描述，所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，仅以上述各功能模块的划分进行举例说明，实际应用中，可以根据需要而将上述功能分配由不同的功能模块完成，即将装置的内部结构划分成不同的功能模块，以完成以上描述的全部或者部分功能。上述描述的系统，装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
