Foreword
It is our great pleasure to welcome you to the Second International Workshop on Privacy and Anonymity in the Information Society (PAIS 2009), collocated with EDBT/ICDT 2009 joint conference. While the ever increasing computational power together with the huge amount of individual data collected daily by various agencies is of great value for our society, they also pose a significant threat to individuals' privacy. As a result legislators for many countries try to regulate the use and the disclosure of confidential information. Data privacy and anonymity have become a mainstream avenue for research. While privacy is a topic discussed everywhere, data anonymity recently established itself as an emerging area of computer science. Its goal is to produce useful computational solutions for releasing data, while providing scientific guarantees that the identities and other sensitive information of the individuals who are the subjects of the data are protected. The workshop is the second in its series and its mission is to provide an open yet focused platform for researchers and practitioners from computer science and other fields that are interacting with computer science in the privacy area such as statistics, healthcare informatics, and law to discuss and present current research challenges and advances in data privacy and anonymity research.
The workshop program features 6 papers that cover a variety of topics, including query auditing; knowledge hiding; measuring risk and utility of anonymized data; specification, analysis, and design of anonymity services; privacy preserving multidimensional data partitioning; and security of social information. In addition, the program includes an invited speech by Dr. Mukesh Mohania, Senior Manager, IBM India Research Lab. The title of his talk is: "Efficient Techniques for Document Sanitization". We hope that you will find this program interesting and thought-provoking. We also hope that the workshop will provide you with valuable opportunities to share ideas with other researchers and practitioners and serve as a catalyst for further research and collaboration. Putting together PAIS 2009 was a team effort. First of all, we would like to thank the authors for providing the quality content of the program. In addition, we would like to express our gratitude to the program committee, who worked very hard in reviewing papers and providing suggestions for their improvements. Finally, we would like to thank the EDBT/ICDT organizers and in particular to the General Chair, Dr. Boris Novikov, for their support of the PAIS 2009 workshop.
