具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
目前，在5G视频客服的业务场景中，需要在视频通话过程中对用户进行人脸认证时，通常在客服侧的终端采用自动抓拍截图的方式来采集用户的人脸图像信息，并将人脸图像信息发送至公安信息系统以完成认证，用户的人脸图像信息存在泄漏的风险，安全性差。
针对在视频通话过程中进行人脸认证时，用户的人脸图像信息存在泄漏的风险的问题，本申请提供了一种视频通话方法、电子设备和存储介质，该方法应用于第一终端，方法包括：第一终端与第二终端建立视频通话；基于预设的数据通道，接收来自第二终端的人脸认证请求信息；响应于人脸认证请求信息，获取人脸图像信息；对人脸图像信息进行隐私保护处理，得到加密信息或者认证信息；基于预设的数据通道，将加密信息或者认证信息发送至第二终端，以使第二终端根据加密信息或者认证信息确定第一终端的人脸认证结果。根据本申请实施例提供的方案，第一终端通过数据通道接收来自第二终端的人脸认证请求信息，然后通过隐私保护处理，得到加密信息或者认证信息，进而将处理得到的信息通过数据通道发送至第 二终端，实现了第二终端通过加密信息或者认证信息来确定第一终端的人脸认证结果，能够避免用户的人脸图像信息泄漏，提高安全性。
下面结合附图，对本申请实施例作阐述。
本申请实施例提供的一种视频通话方法，可应用于第一终端中，也可应用于第二终端中，还可以是运行于第一终端或第二终端中的软件。
如图1所示，图1是本申请一个实施例提供的一种视频通话方法的流程图。该视频通话方法可以应用于第一终端，该视频通话方法包括但不限于如下步骤：
步骤S110，基于预设的数据通道，接收来自第二终端的人脸认证请求信息；
步骤S120，响应于人脸认证请求信息，获取人脸图像信息；
步骤S130，对人脸图像信息进行隐私保护处理，得到加密信息或者认证信息；
步骤S140，基于数据通道，将加密信息或者认证信息发送至第二终端，以使第二终端根据加密信息或者认证信息确定第一终端的人脸认证结果。
可以理解的是，在第一终端与第二终端建立视频通话后，第一终端需要对人脸认证请求信息进行监听，当接收到人脸认证请求信息后，通过预设的图像采集器获取人脸图像信息，然后第一终端对人脸图像信息进行隐私保护处理，再将处理后的结果发送至第二终端，第二终端无法得到原始的人脸图像信息，能够保护用户隐私安全，另外，通过已建立的第一终端和第二终端之间专用的数据通道，完成人脸认证过程的信息传输，能够保证信息传输的可靠性和稳定性；基于此，通过第一终端通过数据通道接收来自第二终端的人脸认证请求信息，然后通过隐私保护处理，得到加密信息或者认证信息，进而将处理得到的信息通过数据通道发送至第二终端，实现了第二终端通过加密信息或者认证信息来确定第一终端的人脸认证结果，能够避免用户的人脸图像信息泄漏，提高安全性。
需要说明的是，第一终端和第二终端可以是个人计算机(Personal Computer，PC)、手机、智能手机、个人数字助手(Personal Digital Assistant，PDA)、可穿戴设备、掌上电脑PPC(Pocket PC)、平板电脑等，但并不局限于此；图像采集器可为单目摄像头、双目摄像头等，但并不局限于此。
在实践中，在5G视频客服的业务场景中，第一终端相当于用户侧的终端，第二终端相当于客服侧的终端，目前，为了保护用户隐私安全，默认情况下，第一终端和第二终端建立视频通话后，第一终端无需开启摄像头，只需观看第二终端的视频业务内容即可，但是在人脸认证场景，用户授权同意后会打开第一终端的摄像头，相对于第一终端直接将人脸图像信息发送至第二终端，以完成人脸认证，用户的人脸图像信息存在泄漏的风险，人脸图像信息泄漏后，人脸图像信息可能被滥用于可视门禁，给用户人身安全带来了隐患；在本实施例提供的视频通话方法中，第一终端对摄像头采集的人脸图像信息进行隐私保护处理，并将处理结果发送至第二终端，第二终端无法得到原始的人脸图像信息，只能通过该处理结果确定第一终端的人脸认证结果，能够避免用户的人脸图像信息泄漏，提高5G视频客服的隐私安全，并提高了5G终端的竞争力。
另外，参照图2，在一实施例中，图1所示实施例中的步骤S130，包括但不限于如下任一步骤：
步骤S210，对人脸图像信息进行加密处理得到加密信息；
步骤S220，对人脸图像信息进行认证处理得到认证信息。
可以理解的是，在隐私保护处理中，第一终端可按照预设的加密规则，对人脸图像信息进行加密处理，得到加密信息，然后将加密信息发送至第二终端，第二终端按照预设的第一认证数据库，对加密信息进行比对分析，确定人脸认证结果，当加密信息与第一认证数据库中的任一信息匹配时，人脸认证结果为通过状态，否则为不通过状态；或者，第一终端可按照预设的第二认证数据库对人脸图像信息进行认证处理，得到用于表征人脸认证结果的认证信息，当人脸图像信息与第二认证数据库中的任一信息匹配时，人脸认证结果为通过状态，否则为不通过状态。
另外，参照图3，在一实施例中，图2所示实施例中的步骤S220，包括但不限于有以下步骤：
步骤S310，将人脸图像信息发送至预设的认证服务器，以使认证服务器对人脸图像信息进行认证处理；
步骤S320，接收来自认证服务器的认证信息。
可以理解的是，第一终端可将人脸图像信息发送至认证服务器，认证服务器相当于公安信息系统，认证服务器储存有包含人脸信息的公安信息，将人脸图像信息和各个公安信息进行比对，得到用于表征人脸认证结果的认证信息，当人脸图像信息与任一公安信息匹配时，人脸认证结果为通过状态，否则为不通过状态。
另外，参照图4，在一实施例中，图1所示实施例中的步骤S110之前，还包括但不限于有以下步骤：
步骤S410，接收来自第二终端的数据通道建立信息；
步骤S420，响应于数据通道建立信息，将预设的配置信息发送至第二终端，以使第二终端根据配置信息，建立与第一终端之间基于互联网协议多媒体子系统IMS域的数据通道。
可以理解的是，第一终端需要对数据通道建立信息进行监听，当接收到数据通道建立信息后，将配置信息发送至第二终端，进而建立第一终端和第二终端之间的IMS数据通道。
需要说明的是，配置信息可由用户预先设置，用户可根据实际需求对配置信息进行更新。
在实践中，数据通道建立信息为第一SIP信令，在第一SIP信令中，通过解析SDP消息中的dcmap字段，来判断是否需要建立数据通道；配置信息包括第一属性标识，按照网络协议的规定，通过第一属性标识确定数据通道的框架，当数据通道的框架为Bootstrap框架，数据通道经过预设的数据服务器，通过该数据通道，第一终端、数据服务器和第二终端依次通信连接；当数据通道的框架为非Bootstrap框架，数据通道不经过数据服务器，通过该数据通道，第一终端和第二终端直接通信连接。
另外，参照图5，在一实施例中，图1所示实施例中的步骤S120之前，还包括但不限于有以下步骤：
步骤S510，获取视频信息；
步骤S520，视频信息进行脱敏处理；
步骤S530，将脱敏处理后的视频信息发送至第二终端。
可以理解的是，相对于第一终端直接将视频信息发送至第二终端，第二终端能够通过对视频信息进行抓拍截图来得到用户的人脸图像信息，人脸图像信息可能被滥用于可视门禁，给用户人身安全带来了隐患；在本实施例提供的视频通话方法中，第一终端和第二终端建立视频通话后，第一终端需要与第二终端进行实时视频时，第一终端获取图像采集器实时采集 的视频信息后，第一终端对视频信息进行脱敏处理，再基于预设的音视频通道，将脱敏处理后的视频信息发送至第二终端，第二终端无法通过脱敏处理后的视频信息得到用户的人脸图像信息，能够避免用户的人脸图像信息泄漏，提高安全性。
另外，参照图6，在一实施例中，图5所示实施例中的步骤S520之前，还包括但不限于有以下步骤：
步骤S610，获取人脸区域参数；
步骤S620，对视频信息进行分帧处理，确定多个视频帧；
步骤S630，根据人脸区域参数，确定各个视频帧的人脸区域。
可以理解的是，在进行脱敏处理前，可基于人脸区域参数，对视频信息中的各个视频帧进行区域限定，确定人脸区域，由于在任一视频帧中，人脸区域以外的区域不存在隐私泄漏的风险，在后续步骤，只需对人脸区域进行脱敏处理，能够在保护隐私安全的前提下，提高效率。
需要说明的是，视频信息包含若干个视频帧的信息，在脱敏处理时，需要对所有视频帧进行处理。
值得注意的是，用户可以在进行视频通话前预先设定人脸区域参数，也可以在视频通话过程中进行设定或调整人脸区域参数。
另外，参照图7，在一实施例中，图5所示实施例中的步骤S520之前，还包括但不限于有以下步骤：
步骤S710，对视频信息进行分帧处理，确定多个视频帧；
步骤S720，对各个视频帧分别进行人脸检测处理，确定各个视频帧的人脸区域。
可以理解的是，在进行脱敏处理前，可通过人脸检测处理，确定视频信息中的各个视频帧的人脸区域，由于在任一视频帧中，人脸区域以外的区域不存在隐私泄漏的风险，在后续步骤，只需对人脸区域进行脱敏处理，能够在保护隐私安全的前提下，提高效率。
另外，参照图8，在一实施例中，图5所示实施例中的步骤S520中的脱敏处理，包括但不限于如下任一步骤：
步骤S810，对人脸区域进行虚化处理；
步骤S820，对人脸区域进行雾化处理；
步骤S830，对人脸区域进行马赛克叠加处理；
步骤S840，对人脸区域进行虚拟形象替换处理。
可以理解的是，通过虚化处理、雾化处理、马赛克叠加处理和虚拟形象替换处理中的一种或多种方式，对人脸区域进行脱敏处理，使第二终端无法通过脱敏处理后的视频信息得到用户的人脸图像信息，能够避免用户的人脸图像信息泄漏，提高安全性。
另外，在一实施例中，图1所示实施例中的步骤S120，包括但不限于有以下步骤：
响应于人脸认证请求信息，基于视频帧的人脸区域，根据视频帧得到人脸图像信息。
可以理解的是，在人脸认证过程中，当第一终端接收到人脸认证请求信息后，第一终端截取视频信息中的当前视频帧，通过该视频帧的人脸区域，确定人脸图像信息，无需通过摄像头重复采集人脸图像，能够提高处理效率。
如图9所示，图9是本申请另一个实施例提供的一种视频通话方法的流程图。该视频通话方法可以应用于第二终端，该视频通话方法包括但不限于如下步骤：
步骤S910，获取人脸认证请求信息；
步骤S920，基于预设的数据通道，将人脸认证请求信息发送至第一终端；
步骤S930，基于预设的数据通道，接收来自第一终端的加密信息或认证信息，其中，加密信息或认证信息由第一终端对人脸图像信息进行隐私保护处理而得到，人脸图像信息由第一终端在响应于人脸认证请求信息的情况下获取而得到；
步骤S940，根据加密信息或认证信息，确定第一终端的人脸认证结果。
可以理解的是，该应用于第二终端的视频通话方法的实施例与上述应用于第一终端的视频通话方法的实施例基本相同，在此不再赘述；基于此，通过第一终端通过数据通道接收来自第二终端的人脸认证请求信息，然后通过隐私保护处理，得到加密信息或者认证信息，进而将处理得到的信息通过数据通道发送至第二终端，实现了第二终端通过加密信息或者认证信息来确定第一终端的人脸认证结果，能够避免用户的人脸图像信息泄漏，提高安全性。
另外，参照图10，图10是本申请另一个实施例提供的IMS数据通道的示意图。
可以理解的是，IMS数据通道可以为Bootstrap框架的数据通道，也可以为非Bootstrap框架的数据通道，如图10所示，当IMS数据通道的框架为Bootstrap框架数据通道经过预设的数据服务器，通过该数据通道，第一终端、数据服务器和第二终端依次通信连接；另外，当数据通道的框架为非Bootstrap框架，数据通道不经过数据服务器，通过该数据通道，第一终端和第二终端直接通信连接(图中未示出)。
另外，参照图11，图11是本申请一个实施例提供的发送视频信息的方法的流程图。
可以理解的是，在视频通话过程中，需要判断第一终端是否处于隐私保护状态，当第一终端处于隐私保护状态时，第一终端才会对视频信息进行脱敏处理，进而将脱敏处理后的视频信息发送至第二终端，否则，第一终端直接将视频发送至第二终端。
需要说明的是，当第一终端与信任的第二终端进行视频通话时，无需对视频信息进行脱敏处理，用户可设置第一终端处于非隐私保护状态，通话效果更佳。
在实践中，在第一终端的通话界面中，设置有隐私保护状态的设置开关，用户可通过触发该开关来调整第一终端的隐私保护状态。
另外，在一实施例中，第一终端包括但不限于：通话模块、采集模块、设置模块、图像处理模块、监听模块、数据通道管理模块、加密模块、发送模块和存储模块。
可以理解的是，通话模块被设置为建立、维持和挂断与第二终端之间的视频通话；采集模块被设置为采集用户的图像信息；设置模块被设置为设置人脸区域参数，以及第一终端的隐私保护状态；图像处理模块被设置为对视频信息进行脱敏处理；监听模块被设置为监控是否接收到人脸认证请求信息或数据通道建立信息；数据通道管理模块被设置为建立、维持、释放IMS数据通道；加密模块被设置为对人脸图像信息按照预设的加密规则进行加密处理；发送模块被设置为将加密信息或认证信息发送至第二终端；存储模块被设置为保存人脸图像信息至本地，以方便后续通过认证服务器对人脸图像信息进行认证处理。
另外，参照图12，本申请的一个实施例还提供了一种电子设备。
在一些实施例中，该电子设备包括：一个或多个处理器和存储器，图12中以一个处理器及存储器为例。处理器和存储器可以通过总线或者其他方式连接，图12中以通过总线连接为例。
