Blockchain technology has the characteristics of transparency and credibility, tamper-proof traceability, privacy security and high reliability of the system, and it is of great significance to study how to apply blockchain technology to improve the logistics and supply chain information system of pandemic prevention materials, so as to better cope with the current and possible future pandemic. To this end, this paper uses the literature analysis method and knowledge map method to reveal the research status, hot spots and evolution context of blockchain technology application in the logistics and supply chain information system under pandemic-hit. The research results show that there is a significant correlation between the number and theme changes of relevant literature and the progress of pandemic prevention and control. There have been a number of research hotspots, but they are still relatively scattered. There are few studies on the organic combination of blockchain technology application, pandemic prevention and control, the logistics and supply chain information system. Looking forward to the research trend, in the future, blockchain can be integrated with the Internet of things, cloud computing, big data, etc., so as to ensure the efficient operation of pandemic emergency logistics, help the management of pandemic material donation, and improve the pandemic medical material supply chain information system.","PeriodicalId":190093,"journal":{"name":"Proceedings of the 2022 4th Blockchain and Internet of Things Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123956261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the different research objects and data completeness of each participant, it is difficult to form effective interconnection and data sharing among databases, the phenomenon of data silos is still serious. Blockchain has the advantages of high trustworthiness, data immutability, and has a high fit with data sharing systems. While data sharing has brought a lot of benefits, a series of problems caused by bogus data have also emerged. Trust issues becomes a prerequisite for the implementation of the data sharing platform. To address these problems, this paper proposes an improved data sharing method based on the consensus algorithm of Proof of Authority (PoA), implements a distributed data transaction authentication system using a consortium blockchain. To improve the throughput and reduce the latency of the consensus mechanism, temporary grouping of PoA validation nodes is performed and different blocks of data transactions are validated in parallel between each group of validation nodes. After the experimental results in this paper, it is shown that the proposed Improved PoA consensus mechanism improves the throughput by 27.65% and reduces the latency by 21.66% than the traditional PoA consensus algorithm.","PeriodicalId":190093,"journal":{"name":"Proceedings of the 2022 4th Blockchain and Internet of Things Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124921338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, private issues become more acute as their data is outsourced to third parties. It is easy for sensitive information to be leaked in a big data environment. To solve these problems, a location data algorithm that satisfies Local Differential Privacy (LDP) is proposed to protect user privacy. In this paper, we use the randomized response mechanism to reconstruct the Laplace algorithm so that it satisfies LDP, perturbing the original location of each user from the client. The user location is clustered using k-means clustering algorithm, the perturbed data are noise reduced in the blockchain software development kit (SDK), and the noise reduced location data is uploaded to the blockchain network for storage through smart contracts. In addition, the effectiveness of the privacy protection mechanism is verified by comparative experiments. Compared with the existing privacy protection methods, the privacy protection mechanism not only can meet the privacy needs of users better, but also the noise reduction algorithm in the SDK can restore the original data and has higher data availability.","PeriodicalId":190093,"journal":{"name":"Proceedings of the 2022 4th Blockchain and Internet of Things Conference","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115952150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, the logistics cloud platform, as a new model of Internet + logistics development, can integrate all the information of service supply chain providers and realize the digitization and networking of logistics resources. However, limited by the existing technology and management mechanism, the development of my country's logistics cloud platform is still in its infancy, and the phenomenon of uneven distribution of power and information asymmetry is expected, which limits the willingness of enterprises to share information to a certain extent. It is also not conducive to the long-term development of the logistics cloud platform. Because of this, this paper builds a logistics cloud platform based on blockchain technology, and explores and solves the problem of information sharing among nodes on the logistics cloud platform. Firstly, analyze the goals and participants of the logistics cloud platform, and then combine the factors that affect information sharing, use blockchain technology to build a logistics cloud platform and outline its functions, and finally compare it with the traditional supply chain, highlighting the blockchain logistics cloud platform The advantages. It is hoped that by building this platform to encourage relevant logistics enterprises to share information, so as to promote the development of the entire logistics industry.","PeriodicalId":190093,"journal":{"name":"Proceedings of the 2022 4th Blockchain and Internet of Things Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114641566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
