Abstract

Editing, reproduction and distribution of the digital multimedia are becoming extremely easier and faster with the existence of the Internet and the availability of pervasive and powerful multimedia tools. However, these advances have their drawbacks as well, for example unauthorized tampering of images. Digital watermarking has emerged as a possible method to tackle these issues. A digital watermark is created by inserting a digital signal, or pattern within multimedia content. This embedded information can be used to determine whether the host data are being tampered with or not. This paper presents a review of watermarking where watermarking processes are described briefly and the appropriate properties for different applications are discussed.
图像水印技术综述
随着互联网的存在和功能强大的多媒体工具的普及,数字多媒体的编辑、复制和发行变得极其容易和快捷。然而,这些进步也有其缺点,例如未经授权的图像篡改。数字水印已经成为解决这些问题的一种可能的方法。数字水印是通过在多媒体内容中插入数字信号或图案而产生的。该嵌入信息可用于确定主机数据是否被篡改。本文对水印技术进行了综述,简要介绍了水印的处理过程,并讨论了不同应用场合的水印特性。
