Embodiment 1

[0007] Embodiment 1: The application scenario of a control method for cross-border flow of data based on blockchain technology is exemplified below: It includes the following steps:

[0008] Data Cross Border Platform (DCBP for short) is a multi-centralized data interaction platform built on the basis of blockchain technology. DCBP does not directly transmit the original data of the enterprise, but interacts with the "cross-border index information" of the original data uploaded by each enterprise data center, and forms multiple backups.

[0009] The cross-border data flow management and control system is an application system based on DCBP. The users of the system include data cross-border customs, the Cyberspace Administration of China, and the Internet Security Bureau. The core functions include data cross-border customs clearance management, data verification, and tax management. etc. The cross-border data flow management and control system is a necessary management tool f...

Abstract

The invention relates to a blockchain technology-based data cross-border flow control method. The method comprises: a data cross-border platform and an established cross-border data flow management and control system. For the problems of data cross-border supervision from traditional sampling check to all data checkability, historical data traceability, cross-border record tampering prevention, record multiple back-ups, automatic auditing, and the like, the blockchain technology is used as a novel technology for comprehensive application, and the blockchain technology has the technical characteristics of distributed consistency, non-tampering, and traceability; the above problems existing in data cross-border supervision can be well solved.

Description

technical field [0001] The invention relates to the application field of block chain, and is a control method for data cross-border flow based on block chain technology. Background technique [0002] Blockchain is a new system of computer technologies such as consensus algorithm, distributed storage, point-to-point transmission, and encryption algorithm. It is widely used in many fields such as securities trading, e-commerce, smart contracts, Internet of Things, social communication, and file storage. The current blockchain technology is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value (hash) of the previous block, and it is guaranteed to be in the previous block in chronological order. After that, it will be generated and connected to the current block from the genesis block to form a block chain. Consensus algorithm is the core technology of blockchain. It determines the efficiency and part of the security of the...
