Description

基于隐私遮蔽显示图像的方法及装置
本申请要求于2016年12月16日提交中国专利局、申请号为201611168947.9发明名称为“基于隐私遮蔽显示图像的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及视频监控领域，特别涉及一种基于隐私遮蔽显示图像的方法及装置。
背景技术
随着公众对隐私保护的日益重视，隐私遮蔽在监控领域的应用也越来越广泛。隐私遮蔽是指为了保护个人隐私，对监控图像中的局部位置进行遮挡或者模糊化处理的方法，其主要应用于图像采集端，比如安装在公共场所或私人场所的监控摄像头等。图像采集端将采集到的图像进行隐私遮蔽后，即可将遮蔽后的图像发送给播放端，由播放端对遮蔽后的图像进行显示。
相关技术中，为了便于用户查看，图像采集端需要提供一份原始图像和一份遮蔽图像。具体地，图像采集端可以采集监控场景的图像，得到一份原始图像，然后获取用户针对该原始图像手动配置的隐私区域或者自动识别该图像中的隐私区域，对该原始图像中的隐私区域进行遮挡或者模糊化处理，得到一份遮蔽图像。对其中的原始图像进行编码和封装，可以得到封装有原始图像的第一多媒体流，对其中的遮蔽图像进行编码和封装，可以得到封装有遮蔽图像的第二多媒体流。之后，通过对播放端的查看权限进行识别，选择性的将第一多媒体流或者第二多媒体流发送给播放端。对于播放端来说，当接收到第一多媒体流时，通过对该第一多媒体流进行解封装和解码，可以播放出原始图像，当接收到第二多媒体流时，通过对该第二多媒体流进行解封装和解码，可以播放出遮蔽图像。
相关技术中，由于图像采集端需要提供一份原始图像和一份遮蔽图像，因此不论存储还是传输的代价都较高，浪费了图像采集端的存储资源和网络资源。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请实施例进行详细的解释说明之前，先对本申请实施例的应用场景予以介绍。本申请实施例提供的方法应用于图像采集及播放系统中，参见图1A，该图像采集及播放系统包括图像采集端10和播放端20。其中，图像采集端10和播放端20可以不连接，也可以通过有线网络或者无线网络进行连接，如图1A所示，本申请实施例对此不做限定。
其中，图像采集端10用于采集图像，并将该图像提供给播放端20，播放端20用于显示该图像。提供方式可以包括：图像采集端10采集图像并存储，播放端20从图像采集端10中获取已存储的图像，例如拷贝已存储的图像；或者，图像采集端10采集图像，并将采集的图像发送至播放端20。
需要说明的是，该图像采集及播放系统中采集和播放的图像可以仅仅是一张图像，比如拍摄的一张照片；或者，该图像也可以为多媒体视频中的一帧图像，也就是该图像采集端可以采集视频，并将该视频提供给播放端，由播放端进行播放，本申请实施例对此不做限定。
进一步地，该图像采集及播放系统还可以为视频编解码系统，相应地，该图像采集端10可以为采集编码端，可以采集图像并对图像进行编码，得到多媒体流，该播放端20可以为解码播放端，可以对采集编码端提供的多媒体流进行解码并播放。
具体地，该图像采集及播放系统可以为视频监控系统，相应地，该图像采集端10可以为监控摄像头，比如固定摄像头，或者球机、云台等活动摄像头等，该播放端20可以为具有显示功能的终端，比如手机、计算机、平板电脑等。或者，该图像采集及播放系统也可以为视频会议系统、视频转播系统等，相应地，该图像采集端10可以为带有摄像头的装置，该播放端20可以为手机、计算机、机顶盒、电视、数字媒体播放器、视频游戏控制台等。
需要说明的是，本申请实施例仅是以图像采集端10和播放端20为两个设备为例，而实际应用中，采集端10和播放端20也可以集成为一个设备，同时具有采集端10和播放端20的功能。例如，该集成的设备可以为摄像机，该摄像机既可以采集图像，也可以对采集的图像进行显示。
另外需要说明的是，为了保护大众隐私，相关的图像采集端10通常可以对采集到的原始图像进行隐私遮蔽。目前的隐私遮蔽方式主要包括两类：
1、手工配置遮蔽区域。用户可以通过特定的设置界面，将图像中的部分区域设置为需要遮蔽的区域，也就是隐私遮蔽区域。例如，在对公共场所进行监控的场景中，为了避免对家庭门窗的监控暴露室内隐私，可以将门窗等固定区域设置为隐私遮蔽区域。
对于固定摄像头来说，由于拍摄的场景固定，因此可以直接将当前设置的区域作为图像中需要遮蔽的隐私遮蔽区域；对于活动摄像头来说，由于所拍摄的图像会随着摄像头的转动而发生变化，因此当用户在某个初始位置下设置了隐私遮蔽区域之后，随着摄像头的转动，该活动摄像头还会根据自身的倍率、朝向等可获知的信息换算初始设置区域应当出现在当前图像中的位置，并将换算后的位置区域作为当前图像中需要遮蔽的隐私遮蔽区域。
2、智能识别遮蔽区域。采用计算机视觉等智能识别方法，对采集到的原始图像进行智能检测，识别其中的运动区域或特定目标，将识别出的运动区 域或者特定目标所处的区域作为需要遮蔽的隐私遮蔽区域。例如，可以将图像中出现的人或车辆所处的区域，识别为隐私遮蔽区域。
但是由于目前的隐私遮蔽方法中，在编码压缩前就已经对配置的或者识别出的隐私遮蔽区域进行了隐私遮蔽处理，导致播放端只能显示遮蔽后的图像，在需要时也无法从原始图像中提取关键信息。为了解决相关技术中存在的问题，在上述图像采集及播放系统中，该图像采集端10可以获取待遮蔽的原始图像，将该原始图像直接提供给播放端20，由播放端20对该原始图像进行识别，得到该原始图像的隐私遮蔽区域信息，基于该隐私遮蔽区域信息确定是否对该原始图像进行隐私遮蔽。或者，获取待遮蔽的原始图像，并获取该原始图像的隐私遮蔽区域信息，将该原始图像和隐私遮蔽区域信息提供给播放端20，由播放端20基于该隐私遮蔽区域信息，确定是否对该原始图像进行隐私遮蔽。
图1B是本申请实施例提供的一种图像采集端10的结构示意图，参见图1B，该图像采集端10包括采集模块11、编码模块12、加密模块13、多媒体封装模块14和输出接口15。
采集模块11，用于对光信息的感知和成像，即将场景光信息转换为图像，其输出一般为原始点阵图像信息，如YUV(一种颜色标准)或RGB(一种颜色标准)色彩模式等。该采集模块11可以为摄影摄像模组或装置，如摄像头等。
编码模块12，用于对输入的图像进行编码形成压缩码流，以减少传输的数据量。

在该实施例中，识别模块17可以对采集到的图像进行智能识别，并将识别得到的隐私遮蔽区域信息输出给多媒体封装模块14，以便该多媒体封装模块14将识别的隐私遮蔽区域信息与加密模块13加密的图像进行封装。
为了便于说明，接下来将图像采集端10配置的隐私遮蔽区域信息称之为第一遮蔽区域信息，将通过识别模块17对图像进行识别得到的隐私遮蔽区域信息称之为第二遮蔽区域信息。

需要说明的是，本申请实施例仅是以图像采集端10包括上述模块为例进行说明，而实际应用中，还可以根据实际需要对上述模块进行相应增减和变换。
图1E是本申请实施例提供的一种播放端20的结构示意图，可以与图1B所示的图像采集端10组成图像采集及播放系统。参见图1E，该播放端20包括输入接口21、多媒体解封装模块22、解密模块23、解码模块24、识别模块25、鉴权模块26、图像合成模块27和显示模块28。

其中，遮蔽信息解析模块29用于对隐私遮蔽区域信息进行解析。由于图像采集端10提供的隐私遮蔽区域信息可能是计算机语言形式的隐私遮蔽区域信息，因此在播放端需要对这种计算机语言形式的隐私遮蔽区域信息进行解析，得到图像合成模块27能够识别的隐私遮蔽区域信息，以便图像合成模块27基于该隐私遮蔽区域信息获知图像中需要遮蔽的区域范围，从而做好在图像中进行隐私遮蔽的准备。
例如，针对图1B，该遮蔽区域信息解析模块29可以对图像采集端10提供的第一遮蔽区域信息进行解析；针对图1C，该遮蔽区域信息解析模块29可以对图像采集端10提供的第二遮蔽区域信息进行解析；针对图1D，该遮 蔽区域信息解析模块29可以对图像采集端10提供的合成的隐私遮蔽区域信息进行解析。

需要说明的是，本申请实施例仅是以播放端20包括上述模块为例进行说明，而实际应用中，还可以根据实际需要对上述模块进行相应增减和变换。
图2是本申请实施例提供的一种基于隐私遮蔽显示图像的方法流程图，参见图2，该方法包括：
步骤201：图像采集端获取待遮蔽的原始图像。
其中，该原始图像可以为图像采集端拍摄的图像，也可以为对拍摄的图像根据第一遮蔽区域信息进行隐私遮蔽得到的原始图像，该第一遮蔽区域信息为该图像采集端配置得到。
具体的，获取待遮蔽的原始图像的方式可以包括以下两种：
第一种方式：获取对监控场景拍摄的图像，将所拍摄的图像确定为该原始图像。也就是，该图像采集端可以通过拍摄，将监控场景的光信息转换为图像，并对该图像不进行任何遮挡或模糊化处理，从而得到该原始图像。
第二种方式：获取对监控场景拍摄的图像；获取配置的第一遮蔽区域信息；根据该第一遮蔽区域信息对所拍摄的图像进行隐私遮蔽，得到原始遮蔽图像；将该原始遮蔽图像确定为该原始图像。
其中，该第一遮蔽区域信息为基于用户的手动配置确定的隐私遮蔽区域信息。当该图像采集端为固定采集端时，该第一遮蔽区域信息即是用户手动配置的隐私遮蔽区域信息，比如该图像采集端保存的用户输入的遮蔽矩形框坐标、遮蔽多边形坐标等；当该图像采集端为活动采集端时，该第一遮蔽区域信息即是通过对用户手动配置的隐私遮蔽区域信息进行活动坐标换算后，得到的隐私遮蔽区域信息。
也就是，该图像采集端可以获取用户手工配置的隐私遮蔽区域信息，根据该手动配置的隐私遮蔽区域信息对所拍摄的图像进行隐私遮蔽，得到该原始图像。
步骤202：图像采集端获取该原始图像的隐私遮蔽区域信息，该隐私遮蔽区域信息用于指示该原始图像中需要遮蔽的区域。
由上述实施环境的介绍可知，目前隐私遮蔽方式包括手工配置隐私遮蔽区域和智能识别隐私遮蔽区域这两种方式，相应地，获取原始图像的隐私遮蔽区域信息可以包括如下方式中的任一种：
第一种方式：将配置的第一遮蔽区域信息确定为该原始图像的隐私遮蔽区域信息。
其中，当该原始图像为所拍摄的图像时，可以获取配置的第一遮蔽区域信息，并将该第一遮蔽区域信息确定为该原始图像的隐私遮蔽区域信息。
第二种方式：对该原始图像进行识别，得到第二遮蔽区域信息，将该第二遮蔽区域信息确定为该原始图像的隐私遮蔽区域信息。
比如，该第二遮蔽区域信息可以为通过识别模块17对该原始图像中的运动区域或者特定目标进行识别后，得到的该运动区域或者该特定目标区域的坐标信息。
其中，当该原始图像为所拍摄的图像或者为原始遮蔽图像时，均可以对该原始图像进行识别，得到第二遮蔽区域信息，并将该第二遮蔽区域信息作为该原始图像的隐私遮蔽区域信息。
第三种方式：获取配置的第一遮蔽区域信息，并对该原始图像进行识别， 得到第二遮蔽区域信息，将该第一遮蔽区域信息和该第二遮蔽区域信息进行合成，得到合成的隐私遮蔽区域信息，将该合成的隐私遮蔽区域信息确定为该原始图像的隐私遮蔽区域信息。
其中，当该原始图像为所拍摄的图像时，可以获取配置的第一遮蔽区域信息，并将该第一遮蔽区域信息确定为该原始图像的隐私遮蔽区域信息。
具体地，将该第一遮蔽区域信息和该第二遮蔽区域信息进行合成的方式可包括：将该第一遮蔽区域信息和该第二遮蔽区域信息的并集，确定为该隐私遮蔽区域信息；或者，将该第一遮蔽区域信息和该第二遮蔽区域信息分别独立描述，不进行逻辑意义上的合成，仅是将该第一遮蔽区域信息和该第二遮蔽区域信息集中在一起，得到隐私遮蔽区域信息。
进一步地，该图像采集端还可以为不同的隐私遮蔽区域信息，设置相同的隐私去遮权限，或者为不同的隐私遮蔽区域信息，设置不同的隐私去遮权限，以便限制播放端只有具有该图像采集端设置的隐私去遮权限时，才能显示不对相应区域进行隐私遮蔽的原始图像。具体设置方式可以包括以下几种：
第一种方式：当该原始图像的隐私遮蔽区域信息为该第一遮蔽区域信息和/或第二遮蔽区域信息时，将对该原始图像不进行隐私遮蔽的权限设置为隐私去遮权限。
也就是，为该隐私遮蔽区域信息设置统一的隐私去遮权限，当播放端具有该隐私去遮权限时，即可对该原始图像不进行隐私遮蔽，从而实现对原始图像中的任意遮蔽区域进行去遮。
第二种方式：当该原始图像的隐私遮蔽区域信息为该第一遮蔽区域信息和/或第二遮蔽区域信息时，将对该原始图像中的第一遮蔽区域不进行隐私遮蔽的权限设置为第一去遮权限和/或将对该原始图像中的第二遮蔽区域不进行隐私遮蔽的权限设置为第二去遮权限，该第一遮蔽区域为该第一遮蔽区域信息指示的区域，该第二遮蔽区域为该第二遮蔽区域信息指示的区域。
也就是，为不同的隐私遮蔽区域信息设置不同的去遮权限，当播放端具有对应的去遮权限时，才能对该原始图像中的对应遮蔽区域不进行隐私遮蔽，从而实现根据对应的去遮权限，对原始图像中的对应遮蔽区域进行去遮。
进一步地，还可以将隐私遮蔽区域信息和对应的隐私去遮权限进行合成，得到合成遮蔽区域信息，播放端可以对该合成遮蔽区域信息进行解析，得到原始图像的隐私遮蔽区域信息和对应的隐私去遮权限。
需要说明的一点是，当该原始图像为多媒体流中的一帧图像时，考虑到若在多媒体流中的每一帧图像中都设置去遮权限，则对于播放端来说，就需要对多媒体流中的每一帧图像都进行鉴权，操作方式过于复杂，因此本申请实施例中，可以仅在多媒体流中的指定帧图像中设置去遮权限，当确定播放端具有该指定帧图像中设置的去遮权限时，即可根据该去遮权限，对该多媒体流中的所有帧图像进行去遮。其中，该指定帧可以为多媒体流中的第一帧或者I帧、P帧等，本申请实施例对此不做限定。
需要说明的另一点是，本申请实施例仅是以在图像采集端中为原始图像设置隐私去遮权限，当播放端具有该原始图像对应的隐私去遮权限时才能对该原始图像进行去遮为例进行说明，而实际应用中，该图像采集端也可以不为原始图像分别设置对应的隐私去遮权限，而是由播放端为所有图像采集端提供的原始图像默认设置统一的隐私去遮权限，当播放端具有对应的隐私去遮权限时，即可对图像采集端提供的所有图像进行去遮。
步骤203：图像采集端将该原始图像和该隐私遮蔽区域信息提供给播放端。
其中，将该原始图像和该隐私遮蔽区域信息提供给播放端的方式可以包括：将该原始图像和该隐私遮蔽区域信息进行存储，由播放端从该图像采集端中获取该已存储的原始图像和隐私遮蔽区域信息，比如从该图像采集端中拷贝已存储的原始图像和隐私遮蔽区域信息；或者，将该原始图像和该隐私遮蔽区域信息发送至该播放端。
进一步地，为了保证原始图像的安全，避免不具有权限的播放端在获取到该原始图像后也能显示该原始图像，导致用户隐私泄露，因此在将该原始图像和该隐私遮蔽区域信息提供给播放端之前，该图像采集端还可以对该原始图像进行加密，从而将加密后的原始图像和该隐私遮蔽区域信息提供该播放端。通过对原始图像进行加密，保证了只有使用专门匹配的、具有对应解密功能的播放端，才能显示该原始图像，而其他第三方播放端或播放器将无法显示该原始图像。
其中，可以使用特定密钥对该原始图像进行加密，则该播放端只有使用该特定密钥才能对加密后的原始图像进行解密，得到该原始图像。
在本申请的一个实施例中，将该原始图像和该隐私遮蔽区域信息提供给播放端的过程可以包括：对原始图像进行编码，得到压缩码流；对压缩码流进行加密，得到加密码流；将加密码流和隐私遮蔽区域信息进行封装，得到多媒体流；将多媒体流提供给播放端。
进一步地，将加密码流和隐私遮蔽区域信息进行封装，得到多媒体流，还可以包括：将加密码流、隐私遮蔽区域信息以及音频、结构化描述符(如字幕)等其他不同属性的信息进行混合封装，得到多媒体流。
需要说明的是，本申请实施例仅是以对压缩码流进行加密为例进行说明，而实际应用中，还可以对多媒体流进行加密，以实现对原始图像的保护，相应地，播放端接收到该加密后的多媒体流之后，还需对该加密后的多媒体流进行解密，才能得到该多媒体流。
步骤204：播放端获取图像采集端提供的原始图像和该原始图像的隐私遮蔽区域信息。
播放端可以从图像采集端中获取该原始图像和隐私遮蔽区域信息，也可以接收该播放端发送的原始图像和隐私遮蔽区域信息，本申请实施例对此不做限定。
这里，接收该播放端发送的原始图像和隐私遮蔽区域信息，包括：播放端从图像采集端中获取该原始图像，播放端对原始图像进行识别得到隐私遮蔽区域信息。
其中，获取图像采集端提供的待遮蔽的原始图像和该原始图像的隐私遮蔽区域信息，可以包括：获取该图像采集端生成的多媒体流，该多媒体流为该图像采集端对该原始图像和该原始图像的隐私遮蔽区域信息进行封装得到；对该多媒体流进行解封装，得到加密码流和该隐私遮蔽区域信息；通过该加密码流的码流密钥对该加密码流进行解密，得到压缩码流；对该压缩码流进行解码，得到该原始图像。
在本申请的另一个实施例中，获取图像采集端提供的待遮蔽的原始图像 和该原始图像的隐私遮蔽区域信息，可以包括：获取该图像采集端生成的多媒体流，该多媒体流为该图像采集端对该原始图像进行封装得到；对该多媒体流进行解封装，得到加密码流；通过该加密码流的码流密钥对该加密码流进行解密，得到压缩码流；对该压缩码流进行解码，得到该原始图像；对原始图像进行识别，得到该原始图像的隐私遮蔽区域信息。
步骤205：播放端根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽，该隐私去遮许可信息用于指示不需要对原始图像进行隐私遮蔽。
其中，该隐私去遮许可信息可以根据接收到的鉴权信息生成得到，该鉴权信息用于对原始图像的显示权限进行鉴权。也就是，播放端可以通过对鉴权信息进行鉴权，来判断是否需要对该原始图像进行隐私遮蔽。
在第一种实现方式中，根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽，可以包括：判断是否存储有隐私去遮许可信息；当存储有该隐私去遮许可信息时，确定不需要对该原始图像进行隐私遮蔽；当未存储有该隐私去遮许可信息时，确定需要对该原始图像进行隐私遮蔽。
相应地，判断是否存储有隐私去遮许可信息之前还包括：接收鉴权信息；判断该鉴权信息是否符合隐私去遮权限，该隐私去遮权限用于指示具有对该原始图像不进行隐私遮蔽的权限，该隐私去遮权限为该原始图像中所携带的权限或者为设置的默认权限；
当该鉴权信息符合该隐私去遮权限时，生成并存储该隐私去遮许可信息。
另外，当该鉴权信息不符合该隐私去遮权限时，播放端还可以生成并存储隐私去遮不许可信息，该隐私去遮不许可信息用于指示需要对该原始图像进行隐私遮蔽。相应地，之后即可在确定存储有该隐私去遮不许可信息时，确定需要对该原始图像进行隐私遮蔽。
在第二种实现方式中，该隐私遮蔽区域信息包括第一遮蔽区域信息和/或第二遮蔽区域信息，这种情况下，根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽，可以包括：
当存储有第一去遮许可信息时，确定不需要对该原始图像中的第一遮蔽区域进行隐私遮蔽，该第一去遮许可信息为一种隐私去遮许可信息，第一去遮许可信息用于指示不需要对第一遮蔽区域进行隐私遮蔽，该第一遮蔽区域为该第一遮蔽区域信息指示的区域；和/或，
当存储有第二去遮许可信息时，确定不需要对该原始图像中的第二遮蔽区域进行隐私遮蔽，该第二去遮许可信息为一种隐私去遮许可信息，第二去遮许可信息用于指示不需要对第二遮蔽区域进行隐私遮蔽，该第二遮蔽区域为该第二遮蔽区域信息指示的区域。
具体地，当该隐私遮蔽区域信息包括第一遮蔽区域信息但不包括第二隐私遮蔽信息时，判断是否需要对该原始图像进行隐私遮蔽可以包括：判断是否存储有第一去遮许可信息；当存储有该第一去遮许可信息时，确定不需要对该原始图像中的该第一遮蔽区域进行隐私遮蔽；当未存储有该第一去遮许可信息时，确定需要对该原始图像中的该第一遮蔽区域进行隐私遮蔽。
当该私遮蔽区域信息包括第二遮蔽区域信息但不包括第一隐私遮蔽信息时，判断是否需要对该原始图像进行隐私遮蔽可以包括：判断是否存储有第二去遮许可信息；当存储有该第二去遮许可信息时，确定不需要对该原始图像中的该第二遮蔽区域进行隐私遮蔽；当未存储有该第二去遮许可信息时，确定需要对该原始图像中的该第二遮蔽区域进行隐私遮蔽。
当该私遮蔽区域信息包括第一遮蔽区域信息和第二隐私遮蔽信息时，判断是否需要对该原始图像进行隐私遮蔽可以包括：判断是否存储有第一去遮许可信息和第二去遮许可信息；当存储有该第一去遮许可信息和该第二去遮许可信息时，确定不需要对该原始图像进行隐私遮蔽；当存储有该第一去遮许可信息但未存储有该第二去遮许可信息时，确定需要对该原始图像中的该第二遮蔽区域进行隐私遮蔽；当存储有该第二去遮许可信息但未存储有该第一去遮许可信息时，确定需要对该原始图像中的该第一遮蔽区域进行隐私遮蔽；当未存储有该第一去遮许可信息和该第二去遮许可信息时，确定需要对该原始图像中的该第一遮蔽区域和该第二遮蔽区域进行隐私遮蔽。
相应地，判断是否判存储有隐私去遮许可信息之前还包括：接收鉴权信息；当该鉴权信息符合第一去遮权限时，生成并存储该第一去遮许可信息， 该第一去遮权限用于指示具有对该原始图像中的第一遮蔽区域不进行隐私遮蔽的权限；当该鉴权信息符合第二去遮权限时，生成并存储该第二去遮许可信息，该第二去遮权限用于指示具有对该原始图像中的第二遮蔽区域不进行隐私遮蔽的权限；其中，该第一去遮权限和该第二去遮权限为该原始图像中所携带的权限或者为设置的默认权限。
另外，当该鉴权信息不符合第一去遮权限时，该播放端还可以生成并存储第一去遮不许可信息，该第一去遮不许可信息用于指示需要对第一遮蔽区域进行隐私遮蔽；当该鉴权信息符合第二去遮权限时，生成并存储第二去遮不许可信息，该第二去遮不许可信息用于指示需要对第二遮蔽区域进行隐私遮蔽。
相应地，之后即可在确定存储有第一去遮许可信息和第二去遮不许可信息时，确定需要对原始图像中的第二遮蔽区域进行隐私遮蔽；当存储有第二去遮许可信息和第一去遮不许可信息时，确定需要对原始图像中的第一遮蔽区域进行隐私遮蔽；当存储有第一去遮不许可信息和第二去遮不许可信息时，确定需要对原始图像中的第一遮蔽区域和第二遮蔽区域进行隐私遮蔽。
实际应用中，该播放端可以在接收到对该原始图像的显示指令，或者对多媒体流的播放指令时，对接收的鉴权信息进行鉴权。
另外，播放端接收鉴权信息的方式可以为内置数据签名的加密狗的方式，比如在播放端中插入类似U盾的USB Key(一种USB接口的硬件设备，有一定的存储空间，可以存储私钥以及数据签名)，相应地，可以通过验证该数据签名来判断该鉴权信息是否符合隐私去遮权限；
或者接收鉴权信息的方式也可以为接收远程服务器发送的授权许可的方式，相应地，可以通过验证该授权许可来判断该鉴权信息是否符合隐私去遮权限，本申请实施例对该鉴权信息的形式和鉴权的方式不做限定。
步骤206：当需要对该原始图像进行隐私遮蔽时，播放端基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽，得到遮蔽图像，并显示该遮蔽图像。
基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽：根据该隐私遮蔽区域信息，确定该原始图像中需要遮蔽的隐私遮蔽区域，对该原始图像中的 隐私遮蔽区域进行隐私遮蔽处理，例如对该隐私遮蔽区域进行遮挡或者模糊化处理，从而形成图像遮蔽，保护隐私。
例如，该播放端可以将该原始图像中隐私遮蔽区域以内的所有像素都置为0，即涂成黑色，以形成图像遮蔽；或者，将该隐私遮蔽区域以内的部分进行模糊处理形成马赛克等。
步骤207：当不需要对该原始图像进行隐私遮蔽时，播放端显示该原始图像。
当不需要对该原始图像进行隐私遮蔽时，该播放端即可不对该原始图像进行任何处理，而直接用于显示，从而可以便于用户从原始图像中提取关键信息。
如此，即可以在需要隐私遮蔽时显示遮蔽图像，也可以在不需要隐私遮蔽时显示原始图像，实现了根据需要对遮蔽图像和原始图像进行灵活的显示，从而在保护用户隐私的同时，保证了能够在需要时从原始图像中提取关键信息，提高了灵活性。
以图1D所示的图像采集端10和图1F所示的播放端20所组成的图像采集及播放系统为例，实际应用中，图1D所示的图像采集端10中的采集模块11可以采集监控场景中的图像，并将该图像作为待遮蔽的原始图像发送至编码模块12和识别模块17；编码模块12将该原始图像进行编码得到压缩码流，将压缩码流发送至加密模块13；加密模块13对该压缩码流进行加密，得到加密码流，并将加密码流发送至多媒体封装模块14；识别模块17可以识别出该原始图像的第二遮蔽区域信息，并将该第二遮蔽区域信息发送至遮蔽信息合成模块18；遮蔽模块16可以获取用户手动配置的第一遮蔽区域信息，并将该第一遮蔽区域信息发送给遮蔽信息合成模块18；遮蔽信息合成模块18可以将该第一遮蔽区域信息和第二遮蔽区域信息进行合成，得到合成的隐私遮蔽区域信息，并将该合成的隐私遮蔽区域信息发送至多媒体封装模块14；多媒体封装模块14可以将该合成遮蔽区域信息和加密码流进行封装，得到多媒体流，并可以将该多媒体流通过输出接口15发送至播放端20。
图1F所示的播放端20中的输入接口21可以接收图像采集端10发送的 多媒体流，并将该多媒体流发送至多媒体解封装模块22；多媒体解封装模块22可以对该多媒体流进行解封装，得到加密码流和合成的隐私遮蔽区域信息，并将加密码流发送至解密模块23，将合成的隐私遮蔽区域信息发送至遮蔽信息解析模块29；解密模块23可以通过该加密码流的码流密匙对该加密码流进行解密，得到压缩码流，并将压缩码流发送至解码模块24；解码模块24可以对该压缩码流进行解码，得到原始图像，并将该原始图像发送至图像合成模块27；遮蔽信息解析模块29可以对该合成的隐私遮蔽区域信息进行解析，得到该图像合成模块27能够识别的遮蔽区域信息；另外，在播放端20播放该多媒体流之前，或者播放该多媒体流的过程中，鉴权模块26还可以接收外部设备发送的鉴权信息，并对该鉴权信息进行鉴权，当符合隐私去遮权限时向图像合成模块27发送隐私去遮许可信息；之后，该图像合成模块27即可基于接收到的隐私去遮许可信息，确定不需要对该原始图像进行隐私遮蔽，并向显示模块28发送该原始图像，该显示模块28即可显示该原始图像；若该图像合成模块27未接收到的隐私去遮许可信息，则即可确定需要对该原始图像进行隐私遮蔽，并基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽，得到遮蔽图像，向显示模块28发送该遮蔽图像，该显示模块28即可显示该遮蔽图像。
另外，以图1B所示的图像采集端10和图1G所示的播放端20所组成的图像采集及播放系统为例，图1B所示的图像采集端10中的采集模块11可以将采集到的图像作为原始图像发送给编码模块12，并通过遮蔽模块16获取手工配置的第一遮蔽区域信息发送给多媒体封装模块14；通过编码模块12和加密模块13对原始图像进行处理得到加密码流，多媒体封装模块14可以将该加密码流和遮蔽模块16发送的第一遮蔽区域信息进行封装，得到多媒体流，并通过输出接口15向播放端20发送该多媒体流。
图1G所示的播放端20可以通过多媒体解封装模块22对接收到的多媒体流进行解封装，得到第一遮蔽区域信息和加密码流；遮蔽信息解析模块29对该第一遮蔽区域信息进行解析可以得到可识别的第一遮蔽区域信息；解密模块23和解码模块24对该加密码流进行处理可以得到该原始图像，并发送给识别模块25；识别模块25对该原始图像进行识别，可以得到第二遮蔽区域信息；遮蔽信息合成模块30对该第一遮蔽区域信息和该第二遮蔽区域信息进行 合成，可以得到合成的隐私遮蔽区域信息；图像合成模块27可以基于遮蔽信息合成模块30发送的合成的隐私遮蔽区域信息，判断是否需要对加密模块24发送的原始图像进行遮蔽，若图像合成模块27接收到的隐私去遮许可信息时，即可不对该原始图像进行隐私遮蔽；若该图像合成模块27未接收到的隐私去遮许可信息，则即可基于该合成的隐私遮蔽区域信息对该原始图像进行隐私遮蔽，得到遮蔽图像。
需要说明的一点是，当鉴权模块26确定鉴权信息符合隐私去遮权限时，可以一直向图像合成模块27发送隐私去遮许可信息，也可以仅向图像合成模块27发送一次隐私去遮许可信息，由图像合成模块27存储该隐私去遮许可信息，并基于存储的隐私去遮许可信息确定不需要对原始图像进行隐私遮蔽，从而直接显示原始图像。
需要说明的另一点是，本申请实施例仅是以上述两种系统为例进行说明，而实际应用中，不同的图像采集端10和播放端20还可以组成其他形式的图像采集及播放系统，具体实施过程可以根据系统的不同进行相应变换，本申请实施例对此不做限定。
本申请实施例提供的方法可以应用于视频监控领域，对于安装在公共场所或私人场所的摄像头而言，则既可以在摄像头记录的视频中尽可能地保护大众的隐私，也可以在出现问题或违法犯罪案件时能够从视频中获得足够的线索，从而较好地满足了不同的场景需求，提高了灵活性。而且需要说明的是，图2实施例中，可以保证不论是手动配置的隐私遮蔽区域信息，还是智能识别的隐私遮蔽区域信息，都可以在获得权限后恢复出遮蔽的原始图像，而且对于播放端的性能也没有较高的要求。
综上所述，本申请实施例中，可以获取图像采集端提供的待遮蔽的原始图像和该原始图像的隐私遮蔽区域信息，之后再根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽，当需要对该原始图像进行隐私遮蔽时，基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽，得到遮蔽图像。如此，图像采集端只需要提供一份原始图像，可以由播放端通过外部鉴权确定是否需要对图像采集端提供的原始图像进行遮蔽，实现对用户隐私的保护，由于图像采集端无需再提供一份原始图像和一份遮蔽图像这两 份图像，因此不论存储还是传输的代价都较低，从而节省了图像采集端的存储资源和网络资源。
图3是本申请实施例提供的一种基于隐私遮蔽显示图像的方法流程图，参见图3，该方法包括：
步骤301：图像采集端获取待遮蔽的原始图像。
其中，该原始图像可以为图像采集端拍摄的图像，也可以为对拍摄的图像根据第一遮蔽区域信息进行隐私遮蔽得到的原始图像，该第一遮蔽区域信息为该图像采集端配置得到。具体实现过程可以参考上述步骤201的相关描述，本申请实施例在此不再赘述。
步骤302：图像采集端将该原始图像提供给播放端。
与图2实施例不同的是，本申请实施例中，该图像采集端可以无需获取该原始图像的隐私遮蔽区域，而是直接将原始图像提供给播放端。
在本申请的一个实施例中，将该原始图像提供给播放端的过程可以包括：对原始图像进行编码，得到压缩码流；对压缩码流进行加密，得到加密码流；将加密码流进行封装，得到多媒体流；将多媒体流提供给播放端。例如，可以将该加密码流和音频、结构化描述符(如字幕)等其他不同属性的信息进行混合封装，得到多媒体流。
步骤303：播放端获取图像采集端提供的原始图像。
步骤303的实现过程可以参考步骤204，本申请实施例在此不再赘述。
步骤304：播放端对该原始图像进行识别，得到隐私遮蔽区域信息。
其中，该隐私遮蔽区域信息即为图2实施例所述的第二遮蔽区域信息。
步骤305：播放端根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽，该隐私去遮许可信息用于指示不需要对该原始图像进行隐私遮蔽。
与图3实施例不同的是，由于播放端只能对原始图像进行识别，得到第二遮蔽区域信息，相应地，也只能对原始图像中的第二遮蔽区域进行隐私遮 蔽，因此，本申请实施例中只需设置一种类型的隐私去遮权限。
也就是，根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽包括：判断是否存储有隐私去遮许可信息；当存储有该隐私去遮许可信息时，确定不需要对该原始图像进行隐私遮蔽；当未存储有该隐私去遮许可信息时，确定需要对该原始图像进行隐私遮蔽。
相应地，判断是否存储有隐私去遮许可信息之前还包括：接收鉴权信息，该鉴权信息用于对该原始图像的显示权限进行鉴权；判断该鉴权信息是否符合隐私去遮权限，该隐私去遮权限用于指示具有对该原始图像不进行隐私遮蔽的权限，该隐私去遮权限为该原始图像中所携带的权限或者为设置的默认权限；当该鉴权信息符合该隐私去遮权限时，生成并存储该隐私去遮许可信息。
步骤306：当需要对该原始图像进行隐私遮蔽时，播放端基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽，得到遮蔽图像，并显示该遮蔽图像。
其中，基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽，也就是，基于第二遮蔽区域信息对该原始图像中的第二遮蔽区域进行隐私遮蔽。
步骤307：当不需要对该原始图像进行隐私遮蔽时，播放端显示该原始图像。
其中，步骤304-307的具体实现方式可以参考图2实施例中的相关描述，本申请实施例在此不再赘述。
如此，即可以在需要隐私遮蔽时显示遮蔽图像，也可以在不需要隐私遮蔽时显示原始图像，实现了根据需要对遮蔽图像和原始图像进行灵活的显示，从而在保护用户隐私的同时，保证了能够在需要时从原始图像中提取关键信息，提高了灵活性。
需要说明的是，图3实施例中只需在图像采集端增加支持对图像或者对码流进行加密的功能即可，可以不更换设备通过固件升级达到，但要求播放端需要具备图像识别的能力，可以识别出图像中的运动区域或特定目标。
以图1B所示的图像采集端10和图1E所示的播放端20所组成的图像采 集及播放系统为例，实际应用中，图像采集端10中的采集模块11可以采集监控场景中的图像，并将该图像作为待遮蔽的原始图像发送至编码模块12；编码模块12将该原始图像进行编码得到压缩码流，将压缩码流发送至加密模块13；加密模块13对该压缩码流进行加密，得到加密码流，并将加密码流发送至多媒体封装模块14；多媒体封装模块14可以将该加密码流进行封装，得到多媒体流，并可以将该多媒体流通过输出接口15发送至播放端20。
或者，图1B所示的图像采集端10中遮蔽模块16还可以获取配置的第一遮蔽区域信息，并根据该第一遮蔽区域信息对采集模块11采集的图像进行隐私遮蔽，得到原始遮蔽图像，并将该原始遮蔽图像作为原始图像发送至编码模块12。
图1E所示，播放端20中的输入接口21可以接收图像采集端10发送的多媒体流，并将该多媒体流发送至多媒体解封装模块22；多媒体解封装模块22可以对该多媒体流进行解封装，得到加密码流，并将加密码流发送至解密模块23；解密模块23可以通过该加密码流的码流密匙对该加密码流进行解密，得到压缩码流，并将压缩码流发送至解码模块24；解码模块24可以对该压缩码流进行解码，得到原始图像，并将该原始图像发送至识别模块25和图像合成模块27；识别模块25可以对该原始图像进行识别，得到第二遮蔽区域信息，并将该第二遮蔽区域信息发送至图像合成模块27；
另外，在播放端20播放该多媒体流之前，或者播放该多媒体流的过程中，鉴权模块26还可以接收外部设备发送的鉴权信息，并对该鉴权信息进行鉴权，当符合隐私去遮权限时向图像合成模块27发送隐私去遮许可信息；之后，该图像合成模块27即可基于接收到的隐私去遮许可信息，确定不需要对该原始图像进行隐私遮蔽，并向显示模块28发送该原始图像，该显示模块28即可显示该原始图像；若该图像合成模块27未接收到的隐私去遮许可信息，则即可确定需要对该原始图像进行隐私遮蔽，并基于该第二遮蔽区域信息对该原始图像中的第二遮蔽区域进行隐私遮蔽，得到遮蔽图像，向显示模块28发送该遮蔽图像，该显示模块28即可显示该遮蔽图像。
需要说明的是，本申请实施例仅是以上述图像采集端10和播放端20组成的图像采集及播放系统为例进行说明，而实际应用中，不同的图像采集端 10和播放端20还可以组成其他形式的图像采集及播放系统，具体实施过程可以根据系统的不同进行相应变换，本申请实施例对此不做限定。
综上所述，本申请实施例中，可以获取图像采集端提供的待遮蔽的原始图像，并对该原始图像进行识别得到隐私遮蔽区域信息，之后再根据是否存储有隐私去遮许可信息，判断是否需要对该原始图像进行隐私遮蔽，当需要对该原始图像进行隐私遮蔽时，基于该隐私遮蔽区域信息对该原始图像进行隐私遮蔽，得到遮蔽图像。如此，图像采集端只需要提供一份原始图像，可以由播放端通过外部鉴权确定是否需要对图像采集端提供的原始图像进行遮蔽，实现对用户隐私的保护，由于图像采集端无需提供一份原始图像和一份遮蔽图像这两份图像，因此不论存储还是传输的代价都较低，从而节省了图像采集端的存储资源和网络资源。
