Blockchain financial big data processing system and method

Abstract

The invention relates to a blockchain financial big data processing system, the blockchain comprises at least five nodes, and each node comprises an encryption module (100), a broadcast module, a receiving module and an identification module. The control module compares the position information detected by the GPS module with the position information of the credit granting area in the big database; and if the Bluetooth module is matched with the Bluetooth shield and the Bluetooth module is matched with the Bluetooth shield, starting a power supply module of the touch screen (101), so that a user can input a login password through the touch screen (101), encrypt the first data and transmit the encrypted first data to a broadcasting module. According to the method, the financial big data serving as the first data are transmitted to each node in the block chain more safely as much as possible. According to the system and the method, the encryption module can carry out double-position authentication on the encryption module before inputting a login password, so that a hacker is prevented from remotely controlling nodes in a block chain, and the security of financial big data is improved.

Description

[0001] The patent application for the present invention is a divisional application. The patent number of the original case is 201811023191.8, and the application date is September 4, 2018. The name of the invention is a blockchain financial big data processing system and method. technical field [0002] The invention relates to a block chain system, in particular to a block chain system for processing financial big data. Background technique [0003] The traditional centralized transaction is a process in which A sends money to the bank, and the bank transfers the money to B. In this process, the bank acts as the center, and its data is easily tampered with. In the blockchain transaction, A sends money to the blockchain, and A broadcasts encrypted information in the blockchain. When more than half of the nodes in the blockchain receive the above broadcast and successfully decode and verify it, the blockchain sends A The money is transferred to B. The above-mentioned block...

[0004] However, the speed of the above-mentioned blockchain transactions is much lower than that of traditional centralized transactions. Therefore, most of the above-mentioned blockchain financial transactions are selected for transaction security, but there are still many security risks in the blockchain transaction link. , especially in financial big data, there are more security risks
