具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请的具体技术方案做进一步详细描述。以下实施例用于说明本申请，但不用来限制本申请的范围。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述本申请实施例的目的，不是旨在 限制本申请。
在以下的描述中，涉及到“一些实施例”，其描述了所有可能实施例的子集，但是可以理解，“一些实施例”可以是所有可能实施例的相同子集或不同子集，并且可以在不冲突的情况下相互结合。
本申请实施例提供一种隐私保护方法，该方法应用于电子设备，该电子设备在实施的过程中可以为各种类型的具有信息处理能力的设备，例如所述电子设备可以包括手机、平板电脑、电子阅读器、笔记本电脑等。该方法所实现的功能可以通过电子设备中的处理器调用程序代码来实现，当然程序代码可以保存在计算机存储介质中，可见，该电子设备至少包括处理器和存储介质。
图1为本申请实施例提供的隐私保护方法的实现流程示意图，如图1所示，该方法可以包括以下步骤101至步骤103：
步骤101，获得第一检测结果，所述第一检测结果用于表征前台使用场景的类型。
该第一检测结果可能是前台使用场景的类型为特定场景，也可能是前台使用场景的类型为非特定场景。
步骤102，获得第二检测结果，所述第二检测结果用于表征周围环境的安全类型。
该第二检测结果可能是周围环境的安全类型为存在偷窥事件，也可能是周围环境的安全类型为无偷窥事件。
步骤103，基于所述第一检测结果和所述第二检测结果，启动相应等级的隐私保护策略。
在一些实施例中，电子设备根据自身是否处于户外场景以及周围环境的安全类型，启动相应等级的隐私保护策略。然而，在该实施例中，即使电子设备处于户外且存在偷窥事件，对于一些前台使用场景也是不需要启动隐私保护策略的。比如，用户正在通过电子设备看电视剧、打游戏、刷短视频、浏览新闻或者阅读某一书籍等，此时即使有他人在偷窥，也没有必要启动隐私保护策略，比如没有必要调低显示屏的亮度或熄屏等；从而，一方面减少影响用户使用体验的情况；另一方面，由于无需启动隐私保护策略，也就无需控制相应器件的工作状态，因此能够一定程度上节约因控制而带来的功耗。
有鉴于此，在本申请提供的隐私保护方法中，不仅考虑了周围环境的安全类型这一因素，还结合了前台使用场景的类型。也就是，基于前台使用场景的类型，以及周围环境的安全类型，启动相应等级的隐私保护策略，从而有针对性地进行隐私保护，进而减少不必要的隐私保护给用户使用体验带来的影响，以及减少不必要的控制给设备带来的功率消耗。
以下分别对上述各个步骤的进一步的可选的实施方式以及相关名词等进行说明。
在步骤101中，获得第一检测结果，所述第一检测结果用于表征前台使用场景的类型。
所谓前台使用场景不包括电子设备所在的物理环境是室内还是室外，而是指电子设备本身的前台使用情况。
在一些实施例中，第一检测结果的确定过程包括：至少满足以下条件中的至少之一，得到所述前台使用场景的类型为特定场景：前台应用的类型是特定类型，前台显示内容包括特定内容，接收到的输入操作是特定操作。
也就是说，在本申请中不限定是基于以上一个或多个因素确定的第一检测结果。比如，如果前台应用的类型是特定类型，则得到的第一检测结果表征的前台使用场景的类型为特定场景；又如，如果前台应用的类型是特定类型且前台显示内容包括特定内容，则得到的第一检测结果表征的前台使用场景的类型为特定场景；再如，如果前台显示内容包括特定内容，则得到的第一检测结果表征的前台使用场景的类型为特定场景；又如，如果接收到的输入操作是特定操作，则得到的第一检测结果表征的前台使用场景的类型为特定场景；等等，至少满足上述条件中的至少之一，确定前台使用场景的类型为特定场景，在此不再过多举例。
所述特定类型可以理解为涉及隐私的应用类型，所述特定类型可以包括开发人员预先设置的应用类型和/或用户自定义的应用类型。特定类型可以是各种各样的，在一些实施例中，特定类型包括聊天应用、金融类应用和/或用户自定义的其他应用等。可以理解地，并非所有类型的应用都需要进行隐私保护，因此，至少基于前台应用的类型是否是特定类型，确定前台使用场景的类型；如此，能够有针对性地启动相应等级的隐私保护策略，从而减少不必要的隐私保护给用户带来的干扰，以及减少不必要的控制给设备带来的功率消耗。
所述特定内容可以理解为涉及隐私的内容。所述特定内容可以包括开发人员预先设置的内容和/或用户预先定义的内容。在一些实施例中，特定内容包括聊天界面、身份证号码、支付密码、解锁密码和/或与用户工作相关的内容等。
所述特定操作可以理解为涉及隐私的操作。在一些实施例中，所述特定操作包括解锁密码输入操作、PIN输入操作、图案输入操作、身份证号码输入操作和/或支付密码输入操作等。
在步骤102中，获得第二检测结果，所述第二检测结果用于表征周围环境的安全类型。
第二检测结果中，周围环境的安全类型或是存在偷窥事件，或是不存在偷窥事件。所谓偷窥是指在未经他人同意的情况下暗中偷看他人隐私信息的行为。在本申请实施例中，对于检测周围环境的安全类型的方法不做限制。在一些实施例中，电子设备可以通过前置摄像头采集图像，然后检测该图像中是否包括非特定对象，如果包括非特定对象，则确定存在偷窥事件。在一些实施例中，电子设备接收录入的人脸图像；识别所述人脸图像中的第一人脸特征；以及，将所述第一人脸特征标记为特定对象的人脸特征。也就是说，用户可以将自己的人脸图像以及允许知道自己隐私内容的人的人脸图像录入在电子设备中，电子设备将接收到 的这些人脸图像中的人脸作为特定对象，提取这些特定对象的图像特征等，以便后续用来检测前置摄像头采集的图像中是否包括非特定对象，从而获得第二检测结果。当然，对于检测周围环境的安全类型的方法并不限定于此，只要能够获得第二检测结果即可。
在一些实施例中，所述方法还包括：识别当前检测的图像中的第二人脸特征；将所述第二人脸特征与所述第一人脸特征进行比较；根据比较结果，确定所述当前检测的图像中是否包括非特定对象和/或特定对象。
比如，当前检测的图像中的至少一个人脸的第二人脸特征与每一录入的第一人脸特征均不相匹配，则确定当前检测的图像中包括非特定对象。
在步骤103中，基于所述第一检测结果和所述第二检测结果，启动相应等级的隐私保护策略。
在本申请实施例中，对于隐私保护策略不做限制，可以是多种多样的。隐私保护策略既可以包括开发人员预先设置的保护策略，也可以包括用户通过配置入口预先配置的保护策略。可选地，在一些实施例中，如果所述第一检测结果表征前台使用场景的类型为特定场景，和/或，所述第二检测结果表征周围环境的安全类型为存在偷窥事件时，至少发出提醒信号，以提醒注意隐私防护。在一些实施例中，发出的提醒信号可以是显性提醒信号，例如弹出通知消息和/或点亮呼吸灯等；如此，相比于仅调整屏幕的显示状态，通过显性提醒的方式，能够使得用户及时知道存在隐私泄漏的风险，从而及时地采取相应的保护措施。
进一步地，在一些实施例中，如表1所示，如果所述第一检测结果表征前台使用场景的类型为特定场景，且所述第二检测结果表征周围环境的安全类型为无偷窥事件，控制呼吸灯以第一颜色发光和/或弹出第一通知消息，所述第一通知消息用于显性提醒注意隐私防护；如果所述第一检测结果表征前台使用场景的类型为非特定场景，且所述第二检测结果表征周围环境的安全类型为存在偷窥事件，控制呼吸灯以第二颜色发光和/或弹出第二通知消息，所述第二通知消息用于显性提醒有人在偷窥；如果所述第一检测结果表征前台使用场景的类型为特定场景，且所述第二检测结果表征周围环境的安全类型为存在偷窥事件，至少调整屏幕的显示状态，从而降低前台显示内容被他人偷窥的风险，以及控制呼吸灯以第三颜色发光和/或弹出所述第二通知消息。
表1

Figure PCTCN2022125372-appb-000002
需要说明的是，第一颜色、第二颜色和第三颜色可以相同，也可以不同。不同时，第三颜色较第二颜色更能够引起用户的注意，第二颜色较第一颜色更能够引起用户的注意。比如，第一颜色为白色，第二颜色为黄色，第三颜色为红色。当然，一级和二级场景中采取的隐私保护策略可以相同，也可以不同，不同时，可选的，在一些实施例中，如果前台使用场景的类型是特定场景，但周围环境的安全类型为无偷窥事件，则弹出第一通知消息；如果前台使用场景的类型为非特定场景，但是却存在偷窥事件，则控制呼吸灯以第二颜色发光，以及弹出第二通知消息。
第一通知消息用于提醒用户当前注意隐私防护，比如，第一通知消息的内容为“请您注意隐私防护”；第二通知消息用于提醒用户有人在偷窥，比如，第二通知消息的内容为“周围有人在偷窥您的屏幕，请注意防护”。当然也不限于是这些内容，第一通知消息和第二通知消息的内容可以是各种各样的，目的是能够显性提醒用户注意隐私防护。
可以理解地，在上述实施例中，无论是一级场景，还是二级场景，相应等级的隐私保护策略均不包括调整屏幕的显示状态，这样就可以减少因调整屏幕的显示状态而干扰用户使用的情况发生，以及因为屏幕显示状态的调整次数的减少，相应也节约了因调整而带来的功耗。而在三级场景中，由于前台使用场景是特定场景，且在该特定场景下还存在偷窥事件，因此采取直接的保护措施，即，至少调整屏幕的显示状态，从而降低前台显示内容被他人偷窥的风险。
在三级场景中，呼吸灯闪烁的颜色可以和一级或二级场景中呼吸灯闪烁的颜色相同或不同。不同时，三级场景中呼吸灯闪烁的颜色更能引人注意。比如，在二级场景中，呼吸灯闪烁的颜色为黄色，而在三级场景中，呼吸灯闪烁的颜色为红色。
可以理解地，调整屏幕的显示状态是为了降低前台显示内容被他人偷窥的风险。在一些实施例中，可以这样调整屏幕的显示状态：调低屏幕亮度、缩小显示内容的部分或全部的字体大小和/或改变显示内容的部分或全部的字体颜色等；或者，还可以直接熄屏，或者，关闭前台显示内容或将这些内容置于后台，从而实现对屏幕的显示状态的调整。总之，对于如何调整屏幕的显示状态不做限制，可以是多种多样的，只要最终能够降低前台显示内容被他人偷窥的风险即可。
在一些实施例中，如果所述第一检测结果表征前台使用场景的类型为非特定场景，且所述第二检测结果表征周围环境的安全类型为无偷窥事件时，维持当前工作状态。
在一些实施例中，所述方法还包括：如果至少K次检测到输入密码错误，且输入密码者不是特定对象，至少执行以下防盗策略中的至少之一：关闭关键应用的操作权限，关闭关机操作的响应功能，获取位置信息和/或物理环境信息，以及将所述位置信息和/或所述物理环境信息上传至指定设备，以便机主根据所述指定设备接收的所述位置信息和所述物理环境信息找回丢失设备；其中，K为大于1的任何特定值。
可选第，所述至少K次是指连续至少K次。在一些实施例中，电子设备的机主本人可以将自己的人脸图像以及允许使用该电子设备的他人的人脸图像录入在该电子设备中，电子设备将接收到的这些人脸图像中的人脸作为特定对象，提取这些特定对象的图像特征等，以便后续用来检测前置摄像头采集的图像中是否包括特定对象，从而确定输入密码者是否是特定对象。
可以理解地，关闭关键应用的操作权限，这样可以使得这些关键应用不响应任何操作，从而防止财产丢失以及隐私泄漏等情况的发生。对于关键应用的类型不做限制，可以是各种各样的，用户也可以自行定义哪个或哪些应用为所述关键应用。比如，关键应用包括可以查看隐私文件的应用、支付类应用、金融类应用或购物类应用等。
关闭关机操作的响应功能，这样可以防止因电子设备被关机而导致的机主本人无法找回该设备的情况发生。比如，如果电子设备已关机，那么电子设备就无法获取自身的位置信息以及物理环境信息，更无法将这些信息上传至指定设备，这就大大增加了机主本人找回该设备的难度。
本申请实施例再提供一种隐私保护方法，图2为本申请实施例提供的另一隐私保护方法的实现流程示意图，如图2所示，该方法包括以下步骤201至步骤206：
步骤201，接收呼出指令，所述呼出指令用于指示呼出隐私保护策略的配置界面；
步骤202，响应于所述呼出指令，显示所述配置界面；
步骤203，基于所述配置界面接收的隐私保护策略配置信息，生成相应等级的新的隐私保护策略；
步骤204，基于所述新的隐私保护策略，更新对应等级的隐私保护策略；
步骤205，接收开启指令，所述开启指令用于指示启动隐私保护进程；
步骤206，响应于所述开启指令，启动所述隐私保护进程，所述隐私保护进程用于执行上述实施例中的步骤。
可以理解地，在本申请实施例中，允许用户自定义配置多级隐私保护策略，以及允许用 户自主开关隐私保护进程；如此，能够更好地适配不同场景下的隐私保护需求以及用户的使用诉求和使用习惯，从而提升用户体验。
隐私泄漏的主要途径包括：用户在通话或网络传输过程中被恶意截取传输数据、手机病毒或流氓APP窃取用户隐私、手机丢失或被盗引起隐私泄漏、以及手机无意间被偷窥引起隐私泄漏等。针对以上不同途径的用户隐私泄漏，主要防护手段有：隐私数据加密、APP访问权限控制、隐私数据隔离存储、应用沙盒、应用签名、身份验证、使用安全键盘进行密码输入和手机贴防偷窥膜等。
下面将说明本申请实施例在一个实际的应用场景中的示例性应用。
在搭载有前置图像处理芯片及始终开启(Always ON，AON)防偷窥功能的手机平台上，实现了一套AON防偷窥功能，该功能可以检测到当前是否有非机主本人在窥视手机屏幕。以下示例性应用基于以上AON防偷窥功能实现了一套多级触发式隐私保护方案，主要思路为：创建一个用户隐私保护后台进程处理具体的隐私保护策略，并与AON防偷窥检测进程及Gatekeeperd守护进程进行通信同步，以获取用户当前手机使用场景。当检测到用户当前的手机使用场景存在不同级别的隐私泄漏可能性时，立即触发用户隐私保护进程中对应级别的隐私保护策略，当隐私泄漏场景消失后，恢复到正常状态，以达到在不同场景下进行检测并保护用户隐私的目的。
除此以外，开发用户界面(User Interface，UI)配置接口使用户可以自主开关隐私保护功能并自定义配置多级隐私保护策略，从而可以更好地适配不同场景下的隐私保护需求与用户的使用诉求和使用习惯。
具体实现方案如下：首先创建一个用户隐私保护进程并作为后台守护进程，可以由用户进行配置后启动，用户隐私保护进程启动后设置异步等待来自Gatekeeperd守护进程及AON防偷窥检测进程的二值信号消息：信号1(即第一检测结果的一种示例)与信号2(即第二检测结果的一种示例)，实现与Gatekeeperd守护进程及AON防偷窥检测进程的通信同步。当用户进行PIN、图案或密码输入时，相应APP会调用Gatekeeperd守护进程进行密码的录入或验证。当Gatekeeperd守护进程检测到状态变更时(由无密码录入或验证，变化为有密码录入或验证，或相反状态变化)，发送信号1给用户隐私保护进程，有密码录入或验证则发送信号1＝TRUE，否则发送信号1＝FALSE；当AON防偷窥检测进程检测到状态变化时(无偷窥事件变化为有偷窥事件或相反状态变化)，发送信号2给用户隐私保护进程，有偷窥事件则发送信号2＝TRUE，否则发送信号2＝FALSE。在用户隐私保护进程中，当未接收到任何信号时，该进程处于休眠状态以降低功耗，当接收到任何信号消息后唤醒并进行信号值判断逻辑，若仅接收到单个信号，另一信号维持前值处理：当信号1＝＝TRUE且信号2＝＝ FALSE时，触发1级隐私保护策略；当信号2＝＝TRUE且信号1＝＝FALSE时，触发2级隐私保护策略；当信号1＝＝TRUE且信号2＝＝TRUE时，触发3级隐私保护策略；当信号1＝＝FALSE且信号2＝＝FALSE时恢复到正常状态。
另外，开发UI配置接口使用户可以自主开关隐私保护功能并自定义配置多级隐私保护策略，当用户打开隐私保护开关时，默认的多级隐私保护策略可配置如下：
1级隐私保护策略：仅发送第一通知消息以通知用户注意当前隐私保护；
2级隐私保护策略：将呼吸灯点亮为黄色闪烁，发送偷窥通知消息(即第二通知消息)；
3级隐私保护策略：将呼吸灯点亮为红色闪烁，发送偷窥通知消息，并调低屏幕亮度或熄屏；
实现流程示意图如图3所示，包括如下步骤301至309：
步骤301，用户打开隐私保护功能的开关；
步骤302，用户可以通过UI界面自定义各级隐私保护策略；
步骤303，用户隐私保护进程作为守护进程启动并在后台运行直到用户关闭隐私保护开关；
步骤304，在用户隐私保护进程中设置异步等待AON防偷窥检测进程和Gatekeeperd守护进程的二值信号通知；若无任何通知，不运行任何隐私保护策略并进入休眠状态以降低功耗；
步骤305，当接收到任何信号消息后唤醒用户隐私保护进程，并对接收到的二值信号值进行判断；若只接收到一个信号，另一信号值则用前值进行判断，信号默认值取FALSE；
步骤306，若信号1＝＝TRUE且信号2＝＝FALSE，表示用户在进行密码输入等隐私操作，但此时并未检测到偷窥事件发生，表示当前环境安全，触发运行1级隐私保护策略，仅对用户作出提醒即可；
步骤307，若信号1＝＝FALSE且信号2＝＝TRUE，表示用户手机正处于被偷窥状态下，但是用户目前并未进行密码输入等隐私操作，用户此时可能会泄漏一些聊天记录等隐私信息，但是没有泄漏密码等的风险，触发运行2级隐私保护策略，通过呼吸灯和消息通知等方式显式通知用户手机已被他人偷窥，需要注意隐私防护；
步骤308，若信号1＝＝TRUE且信号2＝＝TRUE，表示用户当前正在进行密码输入等隐私操作且手机已被人窥视，此时极可能泄漏密码等重要隐私内容，触发3级隐私保护策略，通过呼吸灯和消息通知等方式显式通知用户手机被偷窥且有重要隐私泄漏风险，并通过调低手机屏幕亮度或熄屏等方式防止隐私进一步泄漏；
步骤309，若信号1＝＝FALSE且信号2＝＝FALSE，表示当前无密码输入等隐私操作， 且手机未被他人偷窥，不运行隐私保护策略，恢复正常模式。
相应的时序示意图如图4所示，包括以下步骤401至步骤411：
步骤401，用户隐私保护进程设置异步等待，等待接收信号1和信号2的值，并进入休眠状态；
步骤402，Gatekeeperd守护进程检测到有密码输入操作，发送信号1＝TRUE给用户隐私保护进程；
步骤403，用户隐私保护进程接收到信号1＝TRUE，触发1级隐私保护策略；
步骤404，Gatekeeperd守护进程检测到密码输入操作结束，则发送信号1＝FALSE给用户隐私保护进程；以及
步骤405，AON防偷窥检测进程检测到偷窥事件，发送信号2＝TURE给用户隐私保护进程；
步骤406，用户隐私保护进程接收到信号1＝FALSE，且信号2＝TURE，触发2级隐私保护策略；
步骤407，Gatekeeperd守护进程检测到密码输入操作，发送信号1＝TRUE给用户隐私保护进程；
步骤408，用户隐私保护进程接收到信号1＝TRUE，且信号2的前值为TURE，触发3级隐私保护；
步骤409，Gatekeeperd守护进程检测到密码输入操作结束，发送信号1＝FALSE给用户隐私保护进程；以及
步骤410，AON防偷窥检测进程检测到偷窥事件消失，发送信号2＝FALSE给用户隐私保护进程；
步骤411，用户隐私保护进程接收到信号1＝FALSE和信号2＝FALSE，结束隐私保护策略，恢复正常模式。
基于前文可知，可能存在的状态转移示意图如图5所示，其中，用户将隐私保护功能开启并配置多级的隐私保护策略，基于此用户隐私保护进程启动，转而用户隐私保护进程设置异步等待信号1和信号2；如果用户隐私保护进程未接收到任何信号，则维持之前的隐私保护策略状态，如果之前的隐私保护策略状态为休眠状态，则维持在休眠状态；当用户隐私保护进程接收到信号消息时，对接收的信号消息携带的值进行判断，并根据判断结果执行对应的隐私保护策略；
AON防偷窥检测进程检测到正常状态到偷窥状态的变化，则发送信号2＝TRUE给用户隐私保护进程；如果检测到偷窥状态到正常状态的变化，则发送信号2＝FALSE给用户隐私 保护进程；
Gatekeeperd守护进程检测到无密码录入或验证到有密码录入或验证的状态变化，则发送信号1＝TRUE给用户隐私保护进程；如果检测到有密码录入或验证到无密码录入或验证的状态变化，则发送信号1＝FALSE给用户隐私保护进程。
在本申请实施例中，基于AON防偷窥功能，并进一步结合与gatekeeperd守护进程的通信同步，对用户手机使用场景进行准确感知分类：a、用户在进行密码输入等操作但无偷窥事件发生；b、检测到偷窥事件发生但用户未在输入密码等；c、检测到偷窥事件发生且用户在进行密码输入等操作；在对以上场景进行准备判断及分类的基础上，及时触发对应级别的用户隐私保护策略，给到用户多维度的差异化隐私保护体验；换句话说，能够在不同的手机使用场景下触发不同级别的隐私保护策略，达到根据场景对用户隐私进行多维度保护的目的。
另外，开放隐私保护功能开关接口和多级用户隐私保护策略接口到UI界面，用户通过UI接口可以选择开启或关闭隐私保护功能，并在开启后根据个人喜好进行自定义配置隐私保护策略，使用户可感知且更加适配不同用户的使用诉求和使用习惯；
需要说明的是，该隐私保护方案不仅可以结合Gatekeeperd守护进程获取用户是否在进行密码输入等操作，也可以结合其他进程获取不同类型的信息以适配更多场景的隐私保护需求，比如在后台获取微信等聊天工具启动后触发针对聊天信息的隐私保护策略，或者在后台获取金融类APP启动后触发针对金融资产信息的隐私保护策略；
在一些实施例中，可以在用户隐私保护进程中进一步加入防盗策略：比如当Gatekeeperd守护进程检测到连续多次密码输入错误后，可进一步通过AON防偷窥检测进程检测当前手机使用者是否为机主本人，若非机主本人，立即触发进入防盗托管模式，以防止盗机者进一步操作手机，且可通过AON防偷窥检测进程或GPS传感器等进一步获取手机所处环境及地点信息，并上传云端，机主本人可以通过云端信息更容易地找回手机或进行报警处理。
应当注意，尽管在附图中以特定顺序描述了本申请中方法的各个步骤，但是，这并非要求或者暗示必须按照该特定顺序来执行这些步骤，或是必须执行全部所示的步骤才能实现期望的结果。附加的或备选的，可以省略某些步骤，将多个步骤合并为一个步骤执行，以及/或者将一个步骤分解为多个步骤执行等；或者，将不同实施例中步骤组合为新的技术方案。
