互联网时代下数字化艺术品防伪系统的设计

Design of Anti-counterfeiting System for Digital Works of Art in the Internet Age

随着互联网的快速发展,艺术品的信息交流变得日益便捷,艺术品的数字化存储、传播成为现实,为应和数字化艺术品版权保护的需求以及应对未授权使用所面临的困难提供了新的要求,并越来越被人们所重视。但是,当前我国的数字化艺术品保护仍存在很多问题,严重阻碍我国数字化艺术品的发展与传播。文章对我国数字化艺术品的现状进行阐述,分析艺术品版权保护中存在的问题,并详细设计了一套数字化艺术品保护软件,实现了对数字化艺术品的不可见水印的添加和提取的功能,采用FDCT离散余弦变换作为实现的主要算法。

With the rapid development of the Internet, the information exchange of works of art becomes more and more convenient, and the digital storage and dissemination of works of art become a reality. In order to meet the needs of digital art copyright protection and to deal with the difficulties faced by unauthorized use of new requirements, and has been paid more and more attention. However, there are still many problems in the protection of digital works of art in our country, which seriously hinder the development and dissemination of digital works of art in our country. This paper expounds the present situation of digital works of art in China, analyzes the problems existing in the copyright protection of works of art, and designs a set of software for the protection of digital works of art in detail. The function of adding and extracting invisible watermark of digital art is realized, and the FDCT discrete cosine transform is used as the main algorithm.
