Ensuring privacy on the Internet is one of the most daunting challenges that we presently face. Crowds is the implementation of an approach to provide privacy to web transactions. The system's strategy is to seek concealment through numbers. A crowd consists of a collection of users that intend to participate in web exchanges; each user being represented by a process on their machine called a jondo. The jondo either submits the request to the server or forwards it to another jondo. The randomly achieved sequence of jondos that traverse the distance from the initiator to the server provides degrees of anonymity. The present version of Crowds employs HTTP as its sole protocol to secure anonymity with the exception of embedded protocols. It is the intention of this thesis to extend this system's capability by adding the FTP protocol to its cache of viable protocols traversing the Crowd's implementation.
