At the School of Information Technology, KMUTT, we believe that information te- nology is the most important driver of economy and social development. IT can - able better productivity, as well as helping us to save resources. IT is giving rise to a new round of industrial and business revolution. We now can have products and s- vices that once were believed to be beyond reach. Without IT, it is impossible for people to realize their full potential. Businesses worldwide are harnessing the power of broadband communication, which will have a profound and constructive impact on the economic, social devel- ment, education, and almost all aspects of our life. This new era of unified commu- cation presents us with new challenges. This is why we should work together more closely to enhance the exchange of knowledge related to effective application of broadband communication and IT. It is my sincere hope that all contributions to the Third International Conference on Advances in Information Technology (IAIT 2009) will increase our understanding of how we can have effectively apply this emerging technology for the benefit of all people all around the world. I hope IAIT 2009 will also lead to more research that can contr- ute to a better methodology for IT applications in the era of unified communication. I am very grateful to all our keynotes speakers for coming all the way to Thailand.

It was our intention to organize IAIT 2010 as the place where researchers and ind- trial practitioners could share their work and achievements in information technology, both theoretical and in application. This is the fourth time we have organized IAIT to serve as a venue to foster collaboration among industry and academia from different parts of the world. A lot has been achieved since the launch of the first IAIT in 2005; however, many challenges remain to be addressed in the years to come. IAIT 2010 drew attendance from leading professionals in both industry and academes, as in IAIT 2009. In addition to the relevant program offered by IAIT 2010, the conference p- vided an excellent environment to meet peers in the IT profession, build relationships, and exchange lessons learned. During the conference, participants presented and d- cussed the latest topics in information technology, ranging from technical knowledge and experimentation to future strategic directions. As the Internet continues to reach out even further, almost everything in our daily life is accessible via IP addresses, our societies need to recognize that we need new knowledge to make this advancement become a benefit to all life in this world. It is almost impossible to gain this new knowledge without contributions from our c- leagues, working in various aspects of information technology. Some times, new knowledge found in one area can help simplify difficult task in another. Together we can make our world better by creating applications from information technology.

This book constitutes the proceedings of the 5th International Conference on Advances in Information Technology, IAIT 2012, held in Bangkok, Thailand, in December 2012. The 18 revised papers presented in this volume were carefully reviewed and selected from 37 submissions. They deal with all areas related to applied information technology, such as e-service; information and communication technology; intelligent systems; information management; and platform technology.
