A blockchain traceability system and method based on feature code identification and verification technology

Abstract

The invention provides a block chain traceability system based on feature code identification and verification technology, and the system comprises an collection layer which respectively collects a plurality of state attribute features of an entity through deploying IOT equipment nodes, and enables the collected state attribute features to serve as data to be stored in a data storage file format;a transmission layer which is used for transmitting the acquired state data information to the processing layer through a data transmission protocol, further processing the data and ensuring that thedata can be transmitted under unreliable network conditions; a processing layer which is used for realizing related operations of data analysis and processing, wherein the processing layer comprises adata cleaning module (DCM); a data standardization module DSM (Data Standard Module), a data encryption module DEM (Data Encryption Module) and a data verification module DVM (Data Verification Module); a storage layer which is used for a data storage function; and a presentation layer which is used for executing related operations of the intelligent contract, and automatically executing corresponding rules and query and display operations through the intelligent contract. The invention further discloses a corresponding traceability method.

Description

technical field

[0001] The present invention relates to the technical field of blockchain, in particular to a blockchain traceability system and method based on feature code identification and verification technology. Background technique

[0002] At present, blockchain technology has sprung up suddenly, developed rapidly, and received extensive attention and promotion. The blockchain is essentially a chained data structure that combines the blocks that store data in chronological order. It uses cryptography to ensure safe access to data and is non-tamperable. Through distributed storage and consensus mechanisms Guarantee the openness and transparency of data, and realize data processing and related business operations by using automatically executed smart contract codes. Specifically, the blockchain uses encryption algorithms, consensus mechanisms, and P2P (Point to Point) network-related technologies to ensure that data cannot be tampered with and key data is stored in th...

Examples

specific Embodiment approach

[0064] This embodiment comprises the following steps:

[0065]Step 1: When a new pig is born in a farm, give the pig a fixed ID that uniquely identifies the pig, such as Figure 4 As shown, the fixed ID can include region, farm, date of birth, male and female, and the current time stamp. And upload the fixed ID to the blockchain database. The publishing user or administrator uploads the fixed ID of the pig to the blockchain system through the smart contract.

[0066] In actual demand, pigs are born with a fixed ID, and pigs are traced during the breeding or trading process. Since the status cannot be saved, the authenticity of the pig cannot be further confirmed through the status attribute, and the risk of fraudulent information is still not small. In order to effectively reduce this phenomenon, this embodiment designs a set of dynamic feature code IDs to track the features of pigs in real time.

[0067] Step 2: Collect the three attribute characteristics of pigs through I...
