Multi-card processing method and system based on 5G message and blockchain

Abstract

The invention discloses a multi-card processing method and system based on a 5G message and a blockchain, and relates to the technical field of mobile interconnection. The method comprises the steps that a client receives a card binding request input by a user in the 5G message and sends a mobile phone number of the user to a 5G message server; the 5G message server queries the mobile phone number of the user in a mapping relation between the mobile phone number and a bank card number list pre-stored in a blockchain network to obtain the bank card number list of the user; the client receives all to-be-bound bank card information selected by the user from the list in the 5G message, obtains biological characteristic information of the user and sends the biological characteristic information to a 5G message server; and the server compares the sent biological characteristic information with biological characteristic information of a user pre-stored in a blockchain network, and if the biological characteristic information is consistent with the biological characteristic information, a binding interface of a bank end corresponding to each piece of to-be-bound bank card information is called to complete multi-card binding processing. According to the invention, efficient and safe multi-card processing can be realized.

Description

technical field [0001] The present invention relates to the field of mobile internet technology, in particular to a multi-card processing method and system based on 5G messages and blockchain. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, each customer has bank cards of multiple banks, which is very troublesome to manage. Although some bank APPs or third-party software support the binding of bank cards of different banks, customers need to download the APP, and the process of binding cards requires input. A series of authentications such as card number, verification SMS verification code, input of identity certificate, and input of password are cumbersome to operate, and customer information is not safe during the operation.
