Abstract
The invention provides a payment account secure transaction method and system which improve the transaction security of a payment account through multiple protection means and will not leak the real information of users. The invention adopts the following technical scheme: a user applies for a payment account, an authentication node performs feature extraction on the user's personal information, after checking, the user is added to the payment account transaction block chain node and constrained by the intelligent contract, according to the specific process of payment account transaction, theuser pays or accepts the virtual currency, transmits the virtual currency through ring signature encryption, and extracts the real currency through the clearing node. A credit rating block chain nodeis set to monitor and manage account credit ratings of users and user transactions, if a first violation of a user account during a transaction is monitored, then, the transaction operation of the user account is restricted, and if the second violation behavior of the user transaction object account in the transaction process is monitored, the transaction operation of the user transaction object account is restricted, and other nodes in the block chain are informed of the above-mentioned dishonest behavior in a manner that the true information of the user and the user transaction object is notdisclosed.
Description
technical field [0001] The present invention relates to the field of payment account transactions, in particular to a block chain-based payment account security transaction method and system.
