A few of the papers in this volume were produced through a multi-step process. First, we recorded the talk given by each author at the workshop in May 2008. Next, we transcribed the recording. The authors then produced a draft of their paper from these transcriptions, refining each draft until the final version. Although the papers are not verbatim transcriptions of the talks given, some do retain the informal and conver- sational quality of the presentations. In one instance we have included some material from the question-and-answer period after the talk, since the material covered proved to be relevant and interesting. The majority of authors, however, preferred to include a more formal paper based on the material presented at the workshop. A few notes about language and conventions used in the book. Since some of the authors in this volume come from different parts of the globe we have tried to preserve their native cadences in the English versions of their papers. And finally, a few papers have pictures from screen captures of illustrations or graphics created for computer displays. Although every effort was made to include the highest quality pictures so they would reproduce well in print, in some instances these pictures may not repro- duce as well as might be desired, and we beg the reader’s indulgence. We wanted to thank Rutgers University for their support for the ISIPS Program, DyDAn for sponsoring the workshop and SPARTA, Inc. for their generous contribu- tion for the workshop bags and nametags. We also wanted to thank our many review- ers for help in the paper selection process and the Program Committee for help with the initial direction and planning of the workshop. May 2009 Cecilia S.

Kantor and Michael E. Lesk Rutgers University 4 Huntington Street New Brunswick, NJ [email protected] Abstract. Security is a concern for persons, organizations, and nations. For the individual members of organizations and nations, personal privacy is also a concern. The technologies for monitoring electronic communication are at the same time tools to protect security and threats to personal privacy. Participants in this workshop address the interrelation of personal privacy and national or societal security, from social, technical and legal perspectives. The participants represented industry, the academy and the United States Government. The is- sues addressed have become, if anything, even more pressing today than they were when the conference was held. Keywords: personal privacy, national security, computer security, intelligence agencies. “Three can keep a secret if two of them are dead”-- Poor Richard’s Almanack [1]. 1 Introduction Cooperative behavior is not unique to humans. Ants, bees, even bacteria seem to en- gage in cooperative behavior for survival and for defense against their enemies. But as far as anyone can tell they accomplish this with absolutely no expectation of pri- vacy. And there may have been a point in the development of human intelligence when that was also true. But for all of recorded history and probably well before it, keeping secrets was part and parcel of human communication. In the earliest days, when communication was only by speech, two could keep a secret if each trusted the other and they were sure that no one was within earshot when they discussed the mat- ter. Even that, of course, was subject to some limitations. The mere fact of being seen to go together to some place where you cannot be overheard does alert others to the possibility that there may be a secret there to be discovered. But it was with the introduction of writing, as a method for transferring informa- tion among people who could not speak with each other directly, that security really came into its own. The history of ciphers [2] has been with us for a long time, one of the early recorded ciphers was used by Julius Caesar. As long as written messages had to be carried from one place to another it was necessary that they be protected from C.S. Gal, P.B. Kantor, and M.E.
