On the one hand, User's anonymity is protected in our system ,On the other hand,bank can trace e-coin and owner of e-coin with the help of the group manager ,so it can prevent laundering ,corruption and kidnapping ,and the security of the scheme is based on strong RSA assumption and decision Diffie-Hellman assumption.
