以数字格式共享、传播和呈现数据不仅是一种时尚，而且正在成为我们生活的一部分。如果没有仔细的规划，数字化资源很容易被滥用，特别是那些在互联网上共享的资源。这种滥用的例子包括未经所有者许可的使用，以及修改数字化资源以伪造所有权。防止这种行为的一种方法是采用某种形式的版权保护技术，如数字水印。数字水印是指嵌入到数字源中的数据（例如，图像、文本、音频或视频记录）。它们类似于印刷材料中的水印，因为插入到主媒体中的消息通常成为媒体的组成部分。除了印刷形式的传统水印之外，数字水印也可以是不可见的，可以是图形以外的形式，并且可以被数字地去除。
Sharing, disseminating, and presenting data in digital format is not just a fad, but it is becoming part of our life. Without careful planning, digitized resources could easily be misused, especially those that are shared across the Internet. Examples of such misuse include use without the owner’s permission, and modification of a digitized resource to fake ownership. One way to prevent such behaviors is to employ some form of copyright protection technique, such as digital watermarks. Digital watermarks refer to the data embedded into a digital source (e.g., images, text, audio, or video recording). They are similar to watermarks in printed materials as a message inserted into the host media typically becomes an integral part of the media. Apart from traditional watermarks in printed forms, digital watermarks may also be invisible, may be in the forms other than graphics, and may be digitally removed.
