Description
Technical Field
The invention relates to a commodity information management system, in particular to a commodity traceability dynamic data management system based on a block chain technology.
Background
The tracing system is widely applied to various industries at present, can perform production control, commodity anti-counterfeiting, quality lot and the like on products by directional or non-directional tracing, and is suitable for the whole life cycle of modern products such as production, sale, transportation, use and the like.
The traceability system can realize 100% bidirectional traceability function of all batches of products from raw materials to finished products and from finished products to raw materials. The system has the greatest characteristic function of data safety, and each manual input link is backed up by software in real time. After the system is established, once relevant accidents occur, a supervisor can judge whether the enterprise has a mistake behavior through the system, and the system can be used for searching which link, which step has a problem and who is responsible for the enterprise, so that the difficulty brought to accident handling due to incomplete data, unclear responsibility and the like is avoided, and the problem is solved more quickly. In the tracing process, commodity information needs to be guaranteed not to be tampered, authenticity is kept, and inquiry can be carried out at any time, a traditional tracing system has various means in an encryption link, such as dialing of an after-sale hot line of a commodity manufacturer, logging in of an official platform for inquiry, anti-counterfeiting codes with coatings, various anti-counterfeiting labels and the like, the prior art still has the defects in guaranteeing uniqueness and confidentiality of the anti-counterfeiting label, and particularly has an effective effect in preventing goods fleeing.
The tracing technology has three general types: one is RFID wireless radio frequency technology, a label with a chip is additionally attached to a product package, relevant information can be automatically acquired and read when the product enters and exits a warehouse and is transported, and the flow direction of the product can be recorded on the chip; one is the two-dimensional code, a consumer can inquire related information of a product only by shooting the two-dimensional code through a mobile phone with a camera, inquired records are reserved in the system, and a short message can be directly sent to the consumer once the product needs to be recalled, so that accurate recall is realized; and the other is the bar code added with the product batch information (such as production date, production time, batch number and the like), and the production cost of the production enterprises is not increased basically by adopting the method.
With the rise and development of the block chain concept and technology, the distributed shared account book and the database which have the characteristics of decentralization, no tampering, trace leaving in the whole process, traceability, collective maintenance, public transparency and the like are widely applied. Due to the characteristics, the block chain technology is applied to commodity production management, product traceability and the like, and has a good prospect. The invention patent with application number 201810433070.4 discloses a product tracing method based on a block chain technology, wherein visible information of a product is placed in a common chain, invisible information is placed in a private chain, and effective and comprehensive tracing is realized.
In order to overcome the technical defects, a solution is to independently use a readable and writable RFID tag or other types of chips for each commodity, and read or update information by using a reading and writing device in a link where information needs to be updated, but this method has a high cost for the tag or chip and is difficult to popularize in most commodities, and has a certain requirement for the reading and writing device, and is difficult to be equipped in each link of commodity production and circulation, especially, a terminal consumer has a great obstacle in inquiring about authenticity, updating after-sale service data such as maintenance and the like.
