Ian Goldberg, Eric Brewer, and I wrote a paper giving a high-level introduction to privacy-enhancing technologies for the Internet. Nothing terribly new, but it's about time this stuff made it past oral history and into the literature. To be presented at IEEE COMPCON '97 in February. The paper is available on the web. A html version is at http://www.cs.berkeley.edu/~daw/privacy-compcon97-www/privacy-html.html and there's a postscript version at http://www.cs.berkeley.edu/~daw/privacy-compcon97.ps Comments, critiques, and discussions are welcome.
