The traditional data trustworthiness evaluation method monitors the historical behavior of data subjects, service quality and other characteristics, and then grades the trustworthiness of the data generated by them. However, this evaluation method has great limitations for medical data subjects (patients) who are highly mobile. Therefore, this paper proposes a trustworthiness evaluation method that combines skewed distribution and entropy weight method, classifies medical data and divides multiple evaluation indicators, integrates the weights of each indicator and performs statistical analysis and trustworthiness probability calculation on the indicators, so as to obtain the trustworthiness of the data to be chained and improve the quality of medical services.","PeriodicalId":327964,"journal":{"name":"2022 International Conference on Service Science (ICSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131203524","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}

Adding cache components to the microservice system can significantly improve the concurrency and throughput of the whole microservice framework, and effectively promote the overall performance of the microservice system. However, traditional caching algorithm can easily lead to the imbalance of cache resource allocation in microservice system, thus affecting the performance of the microservice system. We study the basic architecture of cache in microservice platform, and propose the mathematical model of distributed cache and the probability distribution model of data access in microservice platform. Next, based on the above mathematical model, we design a cache replacement algorithm based on dynamic constraints in microservice platform. The algorithm can effectively solve a series of problems of traditional algorithms in microservice platform, making the algorithm more suitable for the environment of microservice architecture. We evaluate and verify the algorithm on the simulation software platform. Experimental results show that the algorithm meets the performance requirements of high cache hit rate, high concurrency and high throughput in the microservice platform, and is significantly better than the traditional cache algorithms.","PeriodicalId":327964,"journal":{"name":"2022 International Conference on Service Science (ICSS)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132402639","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}
