Method, system and device for realizing independent transaction by using electronic signature equipment

Abstract

The invention provides a method, a system and a device for realizing an independent transaction by using electronic signature equipment. The method comprises the steps that first electronic signature equipment sends a transaction request to second electronic signature equipment; the second electronic signature equipment reminds a user holding the second electronic signature equipment of a transaction message; the second electronic signature equipment receives confirmation message for the transaction message, carries out first processing on the transaction message so as to generate a first to-be-verified message, and sends the transaction message and the first to-be-verified message to the first electronic signature equipment; the first electronic signature equipment reminds a user holding the first electronic signature equipment of the transaction information, generates a first transaction data packet according to a predetermined format after receiving the confirmation information for the transaction information and stores the first transaction data packet; and the first electronic signature equipment is networked with a first background server, the first electronic signature equipment sends the first transaction data packet to a first background server, and a procedure that the first background server and a second background server complete transaction operations is executed.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and system for realizing independent transactions by using electronic signature equipment. Background technique [0002] At present, the electronic signature device generally needs to be connected to the background server through the terminal to conduct transactions. For example, when the electronic signature device is a USBKEY, when executing a transaction, the user needs to transfer the transaction information confirmed in the USBKEY through a networked terminal. When USBKEY is not connected to the Internet, it cannot realize offline transfer anytime and anywhere. [0003] With the development of electronic technology, there are a variety of ways to use electronic cash for offline transactions, through the circulation of electronic cash to achieve payment or transfer purposes, such as electronic wallets or payment cards (such as bus IC cards, stored value in shoppi...

Problems solved by technology

However, since the numbers stored in the account are easy to be copied and tampered with, the electronic cash representing the funds may be maliciously altered, for example, the amount in the account is increased, causing the funds to appear out of thin air, resulting in the problem of over-issued cash

Moreover, the existing offline electronic cash transactions have not established a connection with the bank's Internet account system, are not subject to the supervision of the banking system, and have low security
