Abstract(in English) | Postpaid electronic money schemes are provided by credit-card companies. In these schemes, after electronic money is used, its user settles for its credit card. However the credit-card company grasps the most information of trading. Thus, the credit-card company may hurt users' privacy. In addition, since shops can know the information such as ID to specify an individual, users' anonymity may not be kept. This paper proposes a new scheme to keep users' privacy against credit-card companies and to protect users' anonymity against shops. Furthermore, after this scheme are implemented on a PC and a tablet terminal, its feasibility is estimated. |
