His research interests include information forensics, watermarking, multimedia communication and security. He has published more than 80 research papers in major international academic journals and peer-reviewed conference proceedings. Dr.

The traditional digital watermarking technology is relatively mature, but there are some areas has not been fully involved in, such as quantum image watermarking technique and the certification is currently in the initial stage of developing. All of this really solve the.

The Center for Education and Research in Information Assurance and Security (CERIAS) is currently viewed as one of the world’s leading centers for research and education in areas of information security that are crucial to the protection of critical computing and communication infrastructure.

The 1st International Workshop on Digital Watermarking (IWDW), the con- rence covering all aspects of digital watermarking, was held at the Hotel Riviera situated along the beautiful Han River in Seoul, Korea from November 21 to 22, 2002. These proceedings contain 21 papers that were accepted for presentation at the conference.

I. Watermarking techniques can broadly be classified based on their inherent characteristics: visible and invisible (1). Visible watermarks: A visible alteration of the digital image by appending a “stamp” on the image is called a visible watermark. This technique directly maps to that of the pre-digital era where a watermark was imprinted.

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to.

He has obtained a number of research grants (including several large grants from the Australian Research Council) and published numerous research papers in high-quality international journals and conferences. He is the co-inventor of two U.S. patents and some.

In this chapter, the watermarking technique is blind; blind watermarking does not need any of the original images or any information about it to recover watermark. In this technique the watermark is inserted into the high frequencies. Three-level wavelet transform is applied to the image, and the size of the watermark is equal to the size of the detailed sub-band. Significant coefficients are.
