Modeling , Performance Analysis , and Applications of Digital Image Watermarking Systems

As the Internet becomes more and more populous, people concern more about the copyright protection issue for digital data such as images and audio. Digital watermarking technique can hide data in images or audio to indicate the data owner or recipient. Therefore, it can protect the copyright. Motivated by copyright protection in the Internet, we propose an Internet Image Library (IIL) using watermarks to protect the copyright. With this watermarking application– IIL in mind, we analyze and propose new watermark systems to meet this application.
