A Pseudonymous Communications Infrastructure for the Internet

About the talk:
The underlying structure of the Internet Protocol requires users of the Internet to reveal their IP addresses to those with whom they communicate. This and other things (such as cookies) allow data collection, tracking, and other privacy violations without the user's consent. It also makes it difficult for some people to speak out against oppressors (be they an employer or a government), for fear of repercussions.

Anonymous remailers and other so-called "Privacy-Enhancing Technologies" have been around for quite a while, but they are difficult to use, and are often limited in the extent or effectiveness in which they can pretect users' identities.

In this talk, I will discuss protocols for allowing anonymous and pseudonymous use of any IP-based service. These protocols can be leveraged to provide services such as anonymous web browsing, pseudonymous email and newsgroup posting, and private electonic payment systems, and are the basis for Zero-Knowledge Systems' Freedom product.
