Abstract(in English) | Recently, paper based transactions are being replaced by digitized transactions in rapid pace. These kind of digitized data is useful compared to paper based data in sense of the flexibility of the data. Loan Service, (for example, Library, Rental video, debt etc.,) is among the services that makes use of sophisticated digitized transactions. Loan services handle a lot of personal information, which enables the administrators of the information, the analysis of personal hobby and tastes, or even living levels. This leads to a large privacy problem. We examined ways to avoid this privacy problem. One solution is to use "An Anonymous Loan" that the user can be anonymous while borrowing and returning, but the anonymity is unveiled on the due date without return. In this paper, we will suggest a new version "An Anonymous Loan System" that the loan party is allowed to control the number of rights transact by one user, using tamper resistance device and electronic cash scheme for off-line payment. |
