A cross-platform sharing method of digital medical conjoined medical information based on RAFT algorithm
With the rapid development of the digital medical consortium,achieving secure sharing of information among various medical platforms within the consortium is one of the urgent problems to be solved.Therefore,a cross platform sharing method for medical information in the digital medical consortium based on the RAFT algorithm is studied.On the basis of analyzing the architecture of the digital medical consortium,build an information cross platform sharing system that integrates information collection and management,information integration and distribution,platform services,and application services.Among them,the information integration and allocation process uses the RAFT algorithm to achieve data allocation and sharing between data requesters and data providers in the cross platform process of medical information through two functions:node election and log replication.The PageRank algorithm is also used to optimize the node criticality of the RAFT algorithm and improve the integrity of its information sharing.In the experiment,the maximum tolerable number of malicious nodes in this method can reach 16;In 45 seconds,this method can collect nearly 700 pieces of information data;When the number of nodes is 17,the communication complexity of our method is only 262.The experiment shows that this method has a higher tolerance for malicious nodes,faster extraction of massive medical information,and lower communication complexity in the process of sharing information across platforms.
