Cost and communication efficient framework for privacy assured data management cloud

Abstract

Now a days the data on cloud is one of the major concern for the researcher and enterpriser, in respect with cost maintenance, availability for the use with greater reliability over the transfer. Storing the data and hosting with the cheaper cost is one of the major task. Once user put data on cloud he fell confident on data. In this regard we have proposed a scheme where authenticity of data is protected while transfer. This scheme also work for the optimization of cost while transfer from one to other with secure channel for transfer. The optimization of image is very good with the fragmentation of pixel. Time required for the reconstruction of image is very less so that system is more efficient. The chunk of image is decide by the user with fix number so it’s easy to avoid losses in fragmentation. The encryption technic used for the security aspect while transferring data or images. We have provided 2 level security first for chunk with encrypted format and the file where chunk sequence are stored is also in encrypted format We have found that our scheme shows greater performance with the existing system with the variety of aspects.
