Based On Cloud Environment Privacy Protection:the Minority Service Management System Research

With the in-depth development of reform and opening up and the market economy,the population of all ethnic groups is moving faster across urban and rural areas,which puts forward higher requirements for the government to provide public service management.From the perspective of the grassroots,this study uses cloud storage concepts and information technology to build a standardized,high-performance,highly reliable service management system for ethnic minorities.At the same time,the system construction is also facing the problems of information security and privacy protection,the data security problem in cloud environment cannot be ignored.This paper focuses on the research of protecting the confidentiality of data cloud storage.the main contributions are summarized as follows:(1)In order to implement the national ethnic policy,this paper design and implement a service management system for ethnic minorities,and manage the floating population of foreign ethnic minorities through information technology.(2)Analyzing the necessity of cloud as the system data storage environment selection,then we put forward a data confidentiality protection framework and design a cloud service method flow including encryption and password retrieval in view of the defects and risks of cloud storage existing technical solutions.The rich cloud retrieval method meets the system's functional requirements for password content retrieval.And by introducing a local data confidentiality protection system between the client and the cloud,the data processing operation is separated from the cloud to achieve cloud storage,it can separate the cloud storage password and the key,and also reduce the risk of cloud service providers maliciously peeking at private data.(3)Aiming at the security problems in the traditional cloud encryption schemes provided by cloud service providers,we designed privacy protection security target design,and proposed a cloud storage privacy protection method based on segmented recombination and dual algorithm hybrid encryption.Experiment shows that compared with the traditional data encryption protection method,the encryption efficiency and encryption strength can be more effectively considered.This system has been put into use in a certain city at the present stage,and has performed well in its operation.The system construction provided an operational platform for the public service management of ethnic minorities in China.It provides a method reference for improving the cross-regional service management of ethnic minorities' floating population from fragmentation and dissociation to coordination and order,and has application value and practical significance.
