Abstract

Cloud computing is the fundamental for the next computing generation. Cloud computing is
the collection of the resources, all the resources of cloud that are provided across the
internet. For avoiding the unwanted space in the cloud storage the file system is
necessary.de-duplication is most commonly used technique in cloud storage which allows
only one copy of the file to store. De duplication is most useful in reducing the
communication and the storage expenses in the client perspective as well as in the server. In
this paper the main objective is to avoid the duplicated files in the centralized cloud server. A
secure auditing method will convince the client that the storage of data will be secured in the
cloud. Some security problems are raised between the cloud service provider and client, For
that third party auditing has been introduced, the files are classified into four categories they
are sensitive files, confidential files, private clouds, public clouds this will enlarge the
maintenance and management of the large data in the cloud. While uploading the files in the
cloud the most important files will be stored in the sensitive and confidential files and the less
important files will be stored into the private and public cloud. The file which is stored in the
sensitive and in the confidential file will be stored permanently, the files that are uploaded in
the pubic cloud will be deleted after 6 months and files that are stored in the private files will
be deleted after 3 months. The file segmentation is the technique has been involved in this for
the maintenance of the files.
