Abstract

The invention discloses a fingerprint payment certificate server, a fingerprint payment method and a system thereof. The server comprises a prepositioned server, which receives packaged data transmitted by a payment terminal which transacts based on fingerprint information, and comprises a preprocessing unit, a memory and a transaction server, wherein the preprocessing unit unpacks and deciphers the packaged data to obtain fingerprint information data and transaction data; the memory prestores user identity information including pre-acquired user fingerprint characteristic data; the transaction server is in signal connection with the prepositioned server and the memory, and certifies the user identity by comparing the fingerprint information data acquired by the prepositioned server with the fingerprint characteristic data of a corresponding user in the memory; and when the user identity is certified successfully, the transaction data is transmitted to a bank server. The fingerprint payment certificate server plays a role of a third party authenticator between the user and the bank, avoids the problem that impartiality deficiency of proof existing in unilateral certificate, and improves the convenience for user payment at the same time.
