【摘要】：正 一、前言随着当代信息技术的迅猛发展,各种数字化产品、电子出版物(图片、音频、视频、文本等)的发布变得日益流行,数字信息的复制也变得越来越简单。同时,伴随着Internet的日益普及,使得人们可以通过计算机网络传播多媒体资源而带来巨大的商业利润。因此对于内容提供商和版权所有者而言,在网络上发布他们的数字作品(例如数字图像、数字音乐、数字视频等)时如何保护他们的知识产权就成了一个非常迫切的问题。众所周知,网络上传播最为广泛的是各种数字图像,许多个人平面设计者、广告公司、建筑设计单位、报社编辑部门、网
[Abstract]:With the rapid development of contemporary information technology, the release of various digital products and electronic publications (pictures, audio, video, text, etc.) has become more and more popular, and the reproduction of digital information has become more and more simple. At the same time, with the increasing popularity of Internet, people can spread multimedia resources through the computer network and bring huge commercial profits. Therefore, for content providers and copyright owners, how to protect their intellectual property rights when publishing their digital works (such as digital images, digital music, digital video, etc.) on the Internet has become a very urgent issue. As we all know, the most widely distributed digital images on the Internet are many personal graphic designers, advertising agencies, architectural design units, newspaper editing departments, and the Internet.
