In this paper we have designed a partially blind signature scheme for the blinded e-cash based payment system using ECC-based self-certified public key cryptosystems. Using partially blind signatures to design the e-cash scheme can avoid the unlimited growth of the bank's database which keeps all spent e-cashes for preventing double spending, and also let the signer assure himself that the message contains accurate information such as the face value of the e-cash without seeing it. In addition, the proposed e-cash system is constructed using elliptic curve cryptosystems (ECC) under the limited-storage environment such as smart cards, and therefore able to efficiently use smart cards to store the coins. Furthermore, in order to avoid criminals to abuse the anonymity, the proposed electronic payment system is traceable by the trustee in the case of fraudulent transactions. We affirm the proposed efficient security schemes will make the electronic cash payment system securely workable for Internet consumers.
