Problems solved by technology

The problem with this patent is that it can only conduct online transactions. The user’s temporary identity can only be followed by the subsequent transaction process when it is recognized by its own server. When the user cannot communicate with its own server, the payee of this method cannot use it. The user's temporary identity verifies its digital signature on the transaction (in the digital signature based on digital certificate, because the user needs to hide the real identity, it is impossible to provide a digital certificate containing its real identity, and it is impossible to prove the relationship between its temporary identity and its digital certificate Therefore, it

Abstract

The invention discloses a one-time secret key anonymous double-offline transaction method and system based on digital currency. The method comprises the steps that secret keys based on ID cryptography are issued to a money sending party and a receiving party through a secret key management server; using a communication method based on an ID cryptography one-time key to realize near field communication between the credible intermediary and the money sending party and between the credible intermediary and the money receiving party; near field communication between a money sending party and a receiving party is realized by using a communication method, and offline transaction is completed through a trusted intermediary in an offline state; and confirming the transaction through the commercial bank and the central bank in the online state. The method has the beneficial effects that the privacy information of the user can be better protected, so that the transaction (especially the double-offline transaction) is safer.
