基于区块链技术的绿证智能合约交易风险聚类分析模型

Cluster Analysis Model of Green Card Smart Contract Transaction Risk Based on Block Chain Technology

常见的聚类分析模型受到分布式清洁能源接入模式的冲击,内部数据容易被篡改,模型安全性较低。对此,提出基于区块链技术的绿证智能合约交易风险聚类分析模型。引入区块链技术,改变交易信息的哈希结构,将同时生成的区块链证书记入区块链数据库中,作为信息不可篡改的凭证,用于信任认证;设计智能合约响应机制,实现区块链数据的信任认证,在认证完成后,投影区块链数据,完成区块链数据的聚类处理;以聚类结果为依据,构建决策树风险分析模型。实验结果表明,在面对分布式清洁能源接入模式的冲击时,该模型内部数据安全,没有被篡改,安全评估值在4.5以上,自身的安全性得到了提高。

The common cluster analysis model is impacted by the distributed clean energy access mode,the internal data are easy to be tampered,and the security of the model is low.Therefore,a green card smart contract transaction risk cluster analysis model based on blockchain technology is proposed.The blockchain technology is introduced to change the Hash structure of transaction information,and the blockchain certificate generated at the same time is entered into the blockchain database as an information tamper proof certificate for trust authentication.The smart contract response mechanism is designed to realize the trust authentication of blockchain data.After the authentication is completed,the blockchain data are projected to complete the clustering processing of blockchain data.Based on the clustering results,a decision tree risk analysis model is constructed.The experimental results show that in the face of the impact of distributed clean energy access mode,the internal data of the model are secure and have not been tampered.The security evaluation value is more than 4.5,and its own security has been improved.
