Abstract

The invention discloses a data acquisition device based on a blockchain. The data acquisition device comprises a data acquisition system, a blockchain data evidence storage system and at least one blockchain network, wherein the data acquisition system is used for acquiring original data and recording fact proof information of an acquisition event; the blockchain data evidence storage system is used for extracting feature data from collected original data, combining the feature data with fact proof information to generate a synthetic data structure, performing digital signature on the synthetic data structure to generate signature data, and sending the synthetic data structure and the signature data to a blockchain network. And the blockchain network is used for performing signature verification on the signature data through blockchain transaction, and storing the synthesized data structure after the signature verification is passed to complete uplink evidence storage. According to theinvention, information evidence storage is carried out on a data generation event or process, so that evidence instant storage and protection can be carried out on the fact proof information throughthe characteristics of tamper resistance, traceability and the like of the blockchain.

Description

technical field [0001] The present invention relates to block chain technology and data collection technology, especially a block chain-based data collection device to store factual information in the collection or production process through the block chain structure. Background technique [0002] Blockchain is a new system composed 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 trusted certificate deposit, 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 from the genesis block to the current block to form an ordered c...
