步骤S504.如果是音频，则暂停对外发送音频；
步骤S505.如果是是视频，则暂停对外发送视频；
步骤S506.提示用户可能出现泄密，并列出关键字，询问是否继续；
步骤S507.用户选择是，则删除该关键字，不再进行屏蔽；
步骤S508.用户选择否，则暂停通讯30秒；
步骤S509.通讯恢复正常。
图6是本发明可选实施例的高级泄密防护的流程示意图，如图6所示，包括如下步骤：
步骤S601.在防泄密装置上预设关键字；
步骤S602.防泄密装置开始检测音视频码流；
步骤S603.分析检测到的关键字；
步骤S604.如果是音频，则暂停对外发送音频；
步骤S605.如果是是视频，则暂停对外发送视频；
步骤S606.暂停码流发送30秒；
步骤S607.恢复正常的码流发送；
步骤S608.重新开始通讯。
上述高级泄密防护的具体流程，处理比较简单，区别在于高级泄密防护绝对不允许预设关键字出现，一旦出现，通讯立即中断。
本可选实施例提出一种新的音视频通讯中的防泄密方法，核心是在通讯的过程中动态检测可能泄密的部分，动态的进行保护，防止人员疏忽造成的泄密，本可选实施例还有以下可选的的技术手段：
a、可根据需要实时的添加删除关键字，根据场合不同，参与人员不同实时进行调整，非常灵活。
b、可以是软件也可以是独立硬件，可以安置在客户端、服务端、以及网络中转装置中，组网十分灵活，也可以减少用户的成本。
c、可以对音频、视频同时进行检测，在高敏感信息环境，可以有效的防止由于人员疏忽造成的泄密事件发生。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM或RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
本发明的实施例还提供了一种存储介质。可选地，在本实施例中，上述存储介质可以被设置为存储用于执行上述实施例的方法步骤的程序代码。
可选地，在本实施例中，上述存储介质可以包括但不限于：U盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、移动硬盘、磁碟或者光盘等每一种可以存储程序代码的介质。
可选地，在本实施例中，处理器根据存储介质中已存储的程序代码执行上述实施例的方法步骤。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储与存储器中的程序/指令来实现其相应功能。本发明不限于任何特定形式的硬件和软件的结合。
以上所述仅为本发明的可选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有多种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
上述技术问题提高了用户音视频通讯的安全性。
