Abstract
Payment is in nature an act of money transfer from one entity to another, and it is obvious that a payment method will be valued as long as the transaction can be completed with safety no matter what technology was used. The key to U-payment is convenience and security in the transfer of financial information. The purpose of this paper is to find a desirable U-payment scheme promoting seamlessness and privacy with a strong personal device and peer-based information transactions. We propose U-SDT(Secure Direct Transfer) Protocol as a way to make transactions seamless, secure and privacy-protected.
