Description
Technical Field
The invention relates to the technical field of block chain application, in particular to a traffic product authentication tracing system and method based on a block chain technology.
Background
As an authoritative certification authority in the field of traffic products, the central highway science traffic inspection and certification limited company (CTVIC) will also develop from issuing traditional certification vouchers (certification marks, certificates and sample inspection reports) to organically combining certification and traceability.
At present, the traditional tracing technology can be roughly divided into bar code, two-dimensional code and RFID wireless radio frequency technology, although the traditional tracing is widely applied in different industries, the tracing system is based on the current Internet centralized account book mode, or is recorded and stored by each participant in a dispersed and isolated manner, and is an information isolated island mode. In the centralized ledger mode, usually, the certificate-obtaining manufacturer or the channel dealer maintains the centralized ledger, which is the beneficiary in the circulation chain. For accounts maintained by participants in information island mode, there is also the possibility of modifying the compilation in the system. If the certification authority is used as a third party to perform qualified evaluation on product tracing, the certification authority either passively refers to tracing records provided by a manufacturer single party or establishes a data center for collecting data of each product, and for the future world of the internet of things, the operation and maintenance mode is high in cost.
The block chain technology is a recording technology different from a traditional centralized account book accounting mode, is a continuously-increased distributed database which is maintained jointly by multiple parties and can be also called as a distributed shared account book, and is characterized in that a trust relationship is established among the distributed database, the cryptology account book with a non-falsifiable time sequence and a distributed consensus mechanism through a distributed network, data is programmed and operated by an intelligent contract consisting of automatic scripts, and finally the evolution from information interconnection to value interconnection is realized. The block chain is not capable of being tampered and the time stamping capability on the data storage scene, and a powerful tool is provided for source tracing and anti-counterfeiting.
Product enterprises taking 'block chain + traceability' as a development direction are increasing day by day. Related data in the purchasing process, the processing process, the storage process, the transportation process and the selling process of upstream raw materials of the product are linked up and stored by an enterprise, and a client can trace the product by accessing the linked up data. However, due to various customer levels and the limitation of self conditions, professional qualification judgment cannot be performed on the traceability information of each link provided by the enterprise, and whether the enterprise can continuously and stably provide qualified products after certain key raw materials and equipment suppliers are changed cannot be judged. Some enterprises may adopt the detection or authentication result directly in the blockchain traceability platform. For example, CN113177799A provides a block chain-based system and method for anti-counterfeiting traceability of steel, where the system includes a steel asset authentication center intelligent contract module for maintaining authenticated steel asset profile information. The system also comprises a steel asset quality guarantee certificate inquiry module which is used for generating a digital quality guarantee certificate with a fixed format according to the ownership registration information of the property right transfer of the steel asset caused by processing and transaction for the client to distinguish the authenticity. However, this is a fidelity proof for asset circulation that is biased towards asset validation. The function of product authentication is more fundamental in that whether an enterprise has quality assurance capability or not is evaluated in addition to whether products produced by the enterprise meet corresponding product standard requirements or not, whether qualified products can be continuously and stably provided for a long time or not is judged, and product quality fluctuation is avoided. In addition, on the basis of the development of the traditional product authentication service, the qualification evaluation of product tracing is explored, the qualification evaluation dimension of the product can be increased, and the risks brought by product sampling inspection, quality management system files and quality assurance record file sampling evaluation in the original authentication mode are reduced.
