Blockchain information tracking method and system

Abstract

The invention provides a blockchain information tracking method and system, and the method comprises the steps: employing an asymmetric encryption algorithm to generate a key pair, employing the key pair to encrypt an account, employing an electronic signature to carry out the signature processing of a file, and obtaining a first encrypted file; A P2P network is adopted for data transmission, a connection channel is established between a first node and a newly-added node through searching of a server, the newly-added node is made to conduct whole-network broadcasting through a flooding mechanism, and a public key of a key pair is published to the P2P network; Wherein the first encrypted file is stored in a stand-alone designated storage area, and the networking verifies the transmission request through a private key of a key pair; Enabling the first encrypted file to generate a timestamp and then encrypt the timestamp to obtain a second encrypted file, enabling the second encrypted file to generate a public chain, and enabling the public chain to comprise file process information; Verifying the data reading request through the private key of the key pair, reading the public chain after the data reading request passes the verification, and checking the downloaded file. Distributed storage of public key information records at a server side is realized, and the data security performance is ensured.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and system for tracking block chain information. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. The application of blockchain technology in information tracking can greatly save the time of information tracking. [0003] Patent document CN107944894A discloses a method for tracking retail goods based on blockchain technology, which is divided into the first step, which defines the initial information of retail goods and adds them to the genesis block in the blockchain system. Define the c...

Problems solved by technology

However, the above-mentioned patent documents have storage defects in the information transmission method. For each information tracking request, all nodes need to participate in the calculation to calculate the best and nearest node position, resulting in a relatively slow overall efficiency.
