Research On Cloud Storage File Confidentiality Based On File Segmentation

Cloud storage is an emerging network storage technology extended from cloud computing.Current cloud storage applications are widely used due to the powerful functions and the flexibility.On the other hand,Cloud storage is also facing varieties of challenges,especially the cloud data confidentiality,because most of the data security protection methods in cloud storage are based on traditional data encryption technology.Aim at the lack of cloud storage security confidentiality methods.In this dissertation,the original file segmentation method has been improved and proposed a new file segmentation method based on cloud storage data confidentiality method.After analysing the advantages and challenges of current cloud storage technology,This dissertation illustrates the new file segmentation method and explains the algorithms and advantages of the new method.Besides,in this paper,it specifically elaborates the security of the new method through the perspective of probability and information entropy to illustrate the advantages of new methods in applications of cloud storage.then,it discusses the overall operation of the new method including segmenting,uploading,downloading and reorganization of files,and matches them with data storage patterns of cloud storage.At last,the feasibility and advantages of this method in cloud storage applications are obtained.Cloud storage is a very convenient technology.File segmentation method in the file confidentiality has a unique advantage.The use of file segmentation technology in cloud storage has a very good combination of benefits for cloud storage data protection.
