Product information dynamic management system based on block chain

Abstract

The invention discloses a product information dynamic management system based on a block chain. The system includes a product information database, graphic and text information printed on the surfaceof a product package, and a management platform, wherein the product information database is composed of public block chain data and private block chain data,the public block chain data is publicly displayed to the outside; wherein the private block chain data is used for traceability management, the data corresponding to each product comprises public block chain data and private block chain dataat the same time, a specific database address corresponding to each product data generates unique addressing information, the private block chain data is provided with a database key, and the databasekey sets data read-write permission. According to the invention, the mode of combining the platform key information with the graphic and text information is adopted, so that each circulation node canconveniently acquire and update the data in real time on the premise of not modifying the product package or increasing other data acquisition costs.

Description

technical field [0001] The present invention relates to a commodity information management system, in particular to a commodity traceable dynamic data management system based on block chain technology. Background technique [0002] The traceability system has been widely used in various industries. It is a kind of production control, commodity anti-counterfeiting, quality batch, etc. that can track products in a directional or non-directional way. It can be applied to the production, sales, transportation and use of modern products. Wait for the whole life cycle. [0003] The traceability system can realize 100% two-way traceability of all batches of products from raw materials to finished products, and from finished products to raw materials. The biggest characteristic function of this system is the security of data, every link of manual input is backed up by software in real time. After the system is established, once a related accident occurs, supervisors can use the sy...

Problems solved by technology

The invention patent with the application number 201810433070.4 discloses a product traceability method based on blockchain technology, which puts the visible information of the product into the public chain and puts the invisible information into the private chain to achieve effective and comprehensive traceability. Due to the existing characteristics of the distributed decentralized database of blockchain technology, and the commodity data is written in the database in advance, the data information cannot be updated quickly and conveniently in real time, and multi-center collaborative processing is required, which leads to the logistics, warehousing, and consumption of goods after they leave the factory. Information update is difficult to add new dynamic information

[0006] Aiming at the above technical defects, one solution is to independently use readable and writable RFID tags or other types of chips for each product, and use read-write equipment to read or update the information when the information needs to be updated. On the one hand, the cost of tags or chips is high, and it is difficult to popularize most commodities. On the other hand, there are certain requirements for reading and writing equipment, and it is difficult to equip every link of commodity production and circulation, especially when end consumers are checking the authenticity. There are even bigger obstacles when updating after-sales service data such as warranty and maintenance
