【摘要】 随着Internet和网络应用的高速发展,网上交易即电子商务变成了热点,网上交易也成为了图片交易的一种方式,所以如何在网上交易图片是电子商务的一个重要课题。同时,在电子商务环境中,多媒体数字作品包括图片很容易被非法复制和传播,无疑妨碍了电子商务的应用与发展。本文首先研究了图片网系统设计与实现的相关技术,然后对该系统进行了需求分析,接着设计了系统的总体结构和功能模块以及系统的数据库表结构及其关系,最后使用面向对象的设计方法,实现了一个基于B/S、C/S混合架构的图片网系统。该系统应用JAVA技术、MVC模式,使用MySQL后台数据库和Jboss服务器,进行图片资源的网上收集、网上销售,提供图片上传、下载、水印生成、交易和管理等功能,为传媒企业提供了一种现代化的电子数据管理模式,极大地方便了传媒企业对图片资源的管理。本文在研究了数字水印技术的基础上,把DCT域的闭环数字水印技术应用到了该系统,使得图片资源的版权能够得到较好的保护。本文设计的B/S、C/S混合架构的网站系统不仅具有应用价值,而且对于类似电子商务网的构建有理论指导意义。该系统利用数字水印技术实现了图片版权的保护,对图片的网上搜集、交易作了积极的探索。更多还原

【Abstract】 Along with the high-speed development of Internet and network application, Internet trading has gradually become one form of picture transaction. Therefore, how to transact picture on the Internet has become an important subject of e-commerce. At the same time, the illegal duplication and dissemination of multimedia digital works including pictures easily by illegal means undoubtedly hindered the application and development of e-commerce.Firstly, This thesis studies the related technology of the design and implementation of the picture system. Then Requirements Analysis of the system was carried out. After the Requirements Analysis, the overall structure, function module, the structure and relationship of database table are designed, finally, the picture network system which based on the mixed architecture of B/S and C/S was implemented by the use of Object-oriented design methods. This system which use the Java technology, MVC model, backgrounded by MySQL database and JBoss server is able to complete many functions, provide resources collection, online sales, picture upload and download, generation of watermark, transaction, management and so on. This system which provide a modern management model of electronic data for the media business enterprise, Facilitates the management of resources greatly. Based on the study of the digital watermark technology, applied the closed-loop digital watermarking technology of DCT domain on the system, protected the copyright of picture resources effectively.With the mixed structure of B/S and C/S, the website which designed in this thesis not only has practical value, but also has theoretical meaning for the construction of the similar e-commerce website. This picture system which protects the copyright of pictures by the use of watermarking technology actively explored for the development of picture resources collection and transaction.更多还原
