Project Overview Flying Freedom Per Heselius & Martin Hedenfalk
Project Goals Location privacy for mobile internet Anonymous Payment System
Location Privacy, constraints No one should be able to determine the users physical position. Roaming between different networks must be possible.
Payment system, constraints The user should be able to make anonymous payments for the roaming time. Anonymous in this case means that the foreign network should not know the identity of the user paying. The bank should not be able to identify users by the payments the bank receives from the foreign networks. Double spending should not be possible. Double charging should not be possible. Counterfeiting should not be possible. Theft should if possible be prevented.
