Anonymous Web transactions with Crowds 论文

摘要

This article presents a system called Crowds that enables the retrieval of information over the Web without revealing so much potentially private information to several parties. The goal of Crowds is to make browsing anonymous, so that information about either the user or what information he or she retrieves is hidden from Web servers and other parties. Crowds prevents a Web server from learning any potentially identifying information about the user, including even the user's IP address or domain name. Crowds also prevents Web servers from learning a variety of other information, such as the page that referred the user to its site or the user's computing platform
