This series of 10 scholarly essays lays a foundation for understanding the current state of technology-based privacy issues. The diverse group of contributors encompasses the fields of communications, human-computer interaction, law, political science, and sociology. Each contributor provides a capsule view of a privacy concern from a standpoint of where things now stand and what bodes for the future. The book"s most prevalent theme focuses on how advances in cybertechnology have led to greater threats to personal privacy, but have also led to greater promise for privacy protection. For example, editor Philip E. Agre"s opening essay looks at the concept of a "Mirror World," where computer technology mirrors everything important happening in the real world. Another contributor, Victoria Bellotti, examines multimedia environments, where work environments are wired for video and audio communication, and how individuals within them can be protected from unwelcome eyes and ears. Colin Bennett looks at how much of the world may be moving towards similar privacy protection standards. Other issues include varieties of privacy-enhancing technologies, the challenge of controlling surveillance, the effectiveness of privacy laws, and cryptography. The final chapter, "Interactivity as Though Privacy Matters," belongs to Rohan Samarajiva, who looks at the prospects for limited consensual surveillance between vendors and customers.
