An User-centric MIX-net Protocol to Protect Privacy
Alessandro Acquisti · 2002
MIX-net" systems protect the privacy of participants by clouding together their transactions through cascades of third parties. Reliability and trust are therefore open issues in this literature and limit the applicability of these systems. This paper discusses how the MIX approach can be adapted to put the user at the center of the protocol and in control of it, so that each participant can take active steps to protect his or her privacy. The paper also highlights various possible uses of the protocol. Being "in control" comes at a cost, however, and the paper discusses the trade-o#s arising from the proposed approach.
