Cyber security has become one of the most challenging research areas facing academia, industry, and governments. In this talk I will review our research in Intelligence and Security Informatics (ISI), which aims to develop advanced information systems and analytical techniques for security purposes. I will review our internationally acclaimed Dark Web project and discuss our ongoing research in botnets tracking and analysis. An underground community of cyber criminals has grown in recent years with powerful technologies capable of inflicting serious economic and infrastructural harm in the digital age. This talk will serve as an introduction to the world of botnets and to the joint research efforts of the University of Arizona Artificial Intelligence Lab and The ShadowServer Foundation. A data mining exploration is performed on the botnet command & control (C&C) servers to investigate possible characteristics of botnet herders, their targets, attack signatures, and cyber affiliations. The project is partially funded by the US National Science Foundation.

He serves on ten editorial boards including: ACM Transactions on Information Systems, IEEE Intelligent Systems, IEEE Transactions on Systems, Man, and Cybernetics, Journal of the American Society for Information Science and Technology, Decision Support Systems, and International Journal on Digital Library. He has been an advisor for major NSF, DOJ, NLM, DOD, DHS, and other international research programs in digital library, digital government, medical informatics, and national security research. Dr. Chen is founding director of Artificial Intelligence Lab and Hoffman E-Commerce Lab. The UA Artificial Intelligence Lab, which houses 30+ researchers, has received more than $25M in research funding from NSF, NIH, NLM, DOD, DOJ, CIA, DHS, and other agencies. The Hoffman E-Commerce Lab, which has been funded mostly by major IT industry partners, features one of the most advanced e-commerce hardware and software environments in the College of Management. Dr. Chen is conference co-chair of ACM/IEEE Joint Conference on Digital Libraries (JCDL) 2004 and has served as the conference/program co-chair for the past eight International Conferences of Asian Digital Libraries (ICADL), the premiere digital library meeting in Asia that he helped develop. Dr. Chen is also (founding) conference co-chair of the IEEE International Conferences on Intelligence and Security Informatics (ISI) 2003-2009. The ISI conference, which has been sponsored by NSF, CIA, DHS, and NIJ, has become the premiere meeting for international and homeland security IT research. Dr. Chen’s COPLINK system, which has been quoted as a national model for public safety information sharing and analysis, has been adopted in more than 1600 law enforcement and intelligence agencies. The COPLINK research had been featured in the New York Times, Newsweek, Los Angeles Times, Washington Post, Boston Globe, and ABC News, among others. The COPLINK project was selected as a finalist by the prestigious International Association of Chiefs of Police (IACP)/Motorola 2003 Weaver Seavey Award for Quality in Law Enforcement in 2003. COPLINK research has recently been expanded to border protection (BorderSafe), disease and bioagent surveillance (BioPortal), and terrorism informatics research (Dark Web), funded by NSF, CIA, and DHS. In collaboration with selected international terrorism research centers and intelligence agencies, the Dark Web project has generated one of the largest databases in the world about extremist/terrorist-generated Internet contents (web sites, forums, blogs, and multimedia documents). Dark Web research supports link analysis, content analysis, web metrics analysis, multimedia analysis, sentiment analysis, and authorship analysis of international terrorism contents. The project has received significant international press coverage, including: Associated Press, USA Today, NSF Press, Washington Post, Fox News, BBC, PBS, Business Week, Discover magazine, WIRED magazine, Government Computing Week, Second German TV (ZDF), Toronto Star, and Arizona Daily Star, among others. Dr. Chen is the founder of the Knowledge Computing Corporation, a university spin-off company and a market leader in law enforcement and intelligence information sharing and data mining. He has also received numerous awards in information technology and knowledge management education and research including: AT&T Foundation Award, SAP Award, the Andersen Consulting Professor of the Year Award, the University of Arizona Technology Innovation Award, and the National Chiao-Tung University Distinguished Alumnus Award. He was also named Distinguished Alumnus by SUNY Buffalo. Dr. Chen had served as a keynote speaker in major international security informatics, medical informatics, information systems, knowledge management, and digital library conferences. He is a Distinguished/Honorary Professor of several major universities in Taiwan and China (including Chinese Academy of Sciences and Shanghai Jiao Tong University) and was recently named the Distinguished University Chair Professor of the National Taiwan University. Dr. Chen serves as the Program Co-Chair of the International Conference on Information Systems (ICIS) 2009, to be held in Phoenix, Arizona.

Along with the rapid spread of the internet, personal computers and mobile phones, communications via the Internet are now widely and commonly used for daily life. For speech communications, VoIP (voice over IP) is now very widely used over worldwide. Moreover, for audio world, it is now common to download music via the Internet. This naturally results in strong and increasing demand to realize secureness and high-quality with the internet communications. In this keynote, our recent research results relating to data hiding, in a broad sense, to realize secure and high-quality speech and audio communications are introduced.

Digital watermarking to protect copyrights is the most promising application of data hiding. Here, audio watermarking methods based on time-spread echo hiding and phase-rotation are introduced. These methods provide good inaudibility and high detection rate.

Video Forgery is a technique for generating fake video by altering, combining, or creating new video contents. We change the behavior of actors in a video. For instance, the outcome of a 100-meter race in the Olympic Game can be falsified. We track objects and segment motions using a modified mean shift mechanism. The resulting video layers can be played in different speeds and at different reference points with respect to the original video. In order to obtain a smooth movement of target objects, a motion interpolation mechanism is proposed based on reference stick figures (i.e., a structure of human skeleton) and video inpainting mechanism.
