基于WEB的数字水印系统的设计与实现(论文13000字)
【摘要】
互联网的飞速发展使得数字多媒体信息的传播越来越快捷，数字信息可以很轻易地复制传输。人们在利用网络方便的获取信息和交流信息的同时，也加重了对网络传输的安全性以及安全存储能力的关注。
当数字水印技术应用于版权保护时，潜在的应用市场在于电子商务、在线或离线地分发多媒体内容以及大规模的广播服务；应用于隐藏标识时，可在医学、制图、数 字成像、数字图像监控、多媒体索引和基于内容的检索等领域得到应用。在文化艺术领域，人们需要既保证数字化作品的质量，同时又要在其中加入版权标识信息， 防止他人盗版。数字水印的出现解决了人们多元化的需求，因此，在充分利用因特网的便利的基础上安全有效的传输信息时此次课题的研究内容。
本论文利用vs2010工具，通过对LSB算法和DES算法的实现，完成了对BMP载体图片加载BMP秘密信息图片的功能，并且通信双方只能在输入密钥正 确的情况下才能从载体图片中提取出隐藏的秘密信息图片。同时，基于WEB环境的系统实现使得用户省去了下载客户端的步骤，使用起来更加简单绿色，方便快 捷。

Design and implementation
of digital watermarking system based on WEB 
Abstract: The rapid development of the Internet makes the spread of digital multimedia information is increasingly fast and digital information transmission can be easily copied. People use the Internet to facilitate access to information and exchange of information while also increasing concern about the safety and security storage capacity of the network transmission.
When digital watermarking technology used for copyright protection, the potential application market is that e-commerce, online or offline distribution of multimedia content and large-scale broadcasting services; applied to hide the logo can be used in medicine, cartography, digital imaging, digital image monitoring, multimedia indexing and content-based retrieval fields. In the field of arts and culture, people need both to ensure the quality of the digitized works, while at the same time in which by adding copyright identification information, to prevent others from piracy. The emergence of the digital watermark to solve the diverse needs, on the basis of the full use of the Internet to facilitate the safe and effective transmission of information is this subject’s content.
In this thesis, using vs2010 tool and the LSB and DES algorithm, to success the BMP secret picture loaded in the BMP carrier picture, and the communication can only enter the right key to extract the hidden secret picture from the carrier picture. At the same time, the system based on the WEB environment allows the user eliminating the need for steps to download the client and use simple green and convenient.
