Please visit the Center for Internet and Society's new wiki (cyberlaw.stanford.edu/wiki) and contribute to our privacy enhancing technology (PET) database.
Stanford Law School student Seth Gilmore got us started on a PET wiki. As the name suggests, PETs are technologies or techniques that assist users in protecting their information from abuse. They include software allowing for anonymous surfing, plug-ins that reveal who is tracking you online, and improvements in browser security. Microsoft and the Office of the Information and Privacy Commissioner of Ontario, Canada cosponsor an award for PETs, and there is a call for papers (due March 2, 2009) for an upcoming PET conference in Seattle.
