音频和视频水印都可以通过所有者或客户身份验证和检测媒体操作来实现版权保护。现有的水印技术主要针对音频或视频等单一媒体。但是典型的多媒体流包括视频和音频数据。我们的目标是提供一个具有健壮性和脆弱性的解决方案，通过将水印与内容信息结合使用来保证身份验证和完整性。为了实现这一点，必须将视频流解析功能添加到现有的水印算法中。我们提出提取音频和视频内容，称为特征，并将内容特征与鲁棒水印方案嵌入到音频和视频数据中。必须识别音频和视频数据的这些特征。水印有效载荷和特征数据需求必须进行比较。我们的目标是描述我们目前在音频和视频处理方面的工作状态。我们介绍了一种新的a/v内容安全方法。我们在MPEG系统流的视频和音频通道中都嵌入了水印，以增加对内容完整性攻击的安全性。
Both audio and video watermarking enable copyright protection with owner or customer authentication and the detection of media manipulations. The available watermarking technology concentrates on single media like audio or video. But the typical multimedia stream consists of both video and audio data. Our goal is to provide a solution with robust and fragile aspects to guarantee authentication and integrity by using watermarks in combination with content information. To achieve this, video stream parsing capabilities have to be added to existing watermarking algorithms. We propose to extract the audio and video content, called feature, and embed the content features with a robust watermarking scheme into the audio and video data. These features of audio and video data have to be identified. Watermarking payload and feature data requirements have to be compared. Our goal is to describe our current state of work in audio and video processing. We introduce a new approach for a/v content security. We embed watermarks both in video and audio channels of a MPEG system stream to increase security against attacks on content integrity.
