Research And Implementation Of Traceability SYStem With Anti-FAke Ability Based On Blockchain Technology

With the development of blockchain technology,more and more fields are beginning to try the blockchain solutions,for the supply chain scenario,the blockchain is immutable,sorting data by timestamp has the advantage of traceability,but the problem of counterfeiting in the supply chain still exists,consumer and business interests cannot be safeguarded,the current problems with anti-fake technology are:the fake cannot be detected in time,and it is difficult to file counterfeit information;the consumer's reporting process for the problem product is cumbersome;the relevant departments are difficult to blame,and they cannot handle the report in full.In addition,the privacy issues of enterprises or individuals in traditional traceability solutions are also common.The problem of anti-fake ability and users privacy protection in the traceability system need to be solved urgently.Based on the above problems,this article designs and implements a new data security automatic anti-fake scheme based on the traceability capabilities of the blockchain itself.The anti-counterfeiting function is added to the source tracing system,so that counterfeiting can be found,notified in a timely manner.At the same time,it solves the problem of difficult reporting by consumers and strengthens the privacy protection of corporate users.This solution optimizes the traceability system from the anti-fake trusted value algorithm module,multi-role multi-channel privacy protection module,and database enhancement performance module,the main research contents of this article are as follows:(1)Add an anti-fake trusted value algorithm to the source tracing process,and use the analysis ideas of users situation awareness to list the factors that affect the authenticity of the product based on the operations of each role in the source tracing process,analyze the relationship of influence factors and list the calculation formula of anti-counterfeit credible value,through the blockchain smart contract to automatically perform the calculation process,the trusted value will have a specific classification for the hierarchical supervision of relevant departments,similarly,smart contracts will automatically trigger supervision operations,automatically detect and blame the fraudulent behavior.(2)Design a multi-role and multi-channel network to ensure data isolation and security between different users.The nodes in the channel jointly maintain a distributed ledger,but the information in the ledger cannot be seen outside the channel,so as to achieve the purpose of privacy protection.(3)In order to improve the efficiency of the blockchain system,the default database LevelDB in the Hyperledger framework was changed to CouchDB suitable for complex queries.This article studies the anti-counterfeiting technology of the blockchain traceability system and the privacy protection of the blockchain system.Implementing a data security traceability system capable of automatic anti-fake,Testing and analyzing the system,the anti-fake traceability system can handle common anti-fake cases while satisfying user data security..
