We warmly welcome you to ICE-B 2006 - the International Conference on E-business, which is held, this year, in Portugal. This conference reflects a continuing effort to increase the dissemination of recent research among professionals who work on the e-business field. ICE-B is integrated as one of the modules of the ICETE joint conference. The fact that new tools are enabling researchers to better understand how people think and work means that all professions must quickly acquire and quickly apply new knowledge. Globalization means that more information is available, faster. This conference will help the creators of new knowledge quickly reach the people who can best apply that knowledge in e-commerce. The major goal of ICETE is to bring together researchers, engineers and practitioners interested in information and communication technologies, including e-business, wireless networks and information systems, security and cryptography, signal processing and multimedia applications.
These are the main knowledge areas that define the four component conferences, namely: ICE-B, WINSYS, SECRYPT and SIGMAP, which together form the ICETE joint conference. In the program for this joint conference, we have included keynote lectures, tutorials, papers, and posters to present the widest possible view on these technical areas. With these tracks, we expect to appeal to a global audience of engineers, scientists, business practitioners and policy experts, interested in the research topics of ICETE. All tracks focus on real world applications and rely on contributions from the industry, with different solutions for end-user applications and enabling technologies, in a diversity of communication environments. The proceedings demonstrate a number of new and innovative solutions for e-business and telecommunication, and demonstrate the vitality of these research areas. We have received 326 papers in total, with contributions from 53 different countries, from all continents, which really shows the success and global dimension of ICETE 2006. To evaluate each submission, a double blind paper evaluation method was used: each paper was reviewed by at least two internationally known experts from our Program Committee, and more than 95% of the papers had 3 reviews or more. In the end, 98 papers were selected to be published and presented as full papers, 30’ oral presentations, corresponding to a 30% full paper acceptance ratio; 105 additional papers were published and presented, including short papers and posters, corresponding to a 62% total acceptance ratio. Furthermore, a short list of about thirty top-quality papers will be selected to appear in a book that will be published by Springer. We would like to emphasize the fact that ICETE 2006 includes one tutorial and seven outstanding keynote lectures in areas which are very relevant, nowadays. These talks are presented by distinguished researchers who are internationally recognized experts in all ICETE areas, and contribute to heighten the overall interest of the Conference. ICETE 2006 is a joint conference that has achieved a high quality level, which we hope and strive not only to maintain but even increase in next year’s conference, ICETE 2007, which is already planned to be held in Barcelona/Spain. But life is more than technology, so a Conference Banquet was planned for the evening of August 9 (Wednesday) in order to facilitate social networking. We hope that you enjoy this exciting conference and we wish you an unforgettable stay in the beautiful city of Setúbal. We would like to express our thanks, first of all, to the authors of the technical papers presented at the conference, whose work made possible to put together a high quality program. Next, we would like to thank all the members of the program committee and reviewers, who helped us with their expertise, dedication and time. We would also like to thank the invited speakers for their invaluable contribution, sharing their vision and knowledge. Naturally, a word of appreciation for the work of the secretariat and all other members of the organization, whose diligence in dealing with all organizational issues were essential and required a collaborative effort of a dedicated and highly capable team. We hope that you will find these proceedings interesting and a helpful reference in the future for all those who need to address the areas of e-business and telecommunications.
