Abstract

Cloud computing is a successful environment due to many recent technologies. The main advantage of using cloud computing is that it allows users to store a copious amount of data. The mobile data which has been redistributed to the third party cloud requires protection from the trapdoor, intruders to do so the data were encrypted using asymmetric encryption into blocks and then distributed to the various cloud storages. But there exists some difficulties in search of those data in cloud, which may not give an accurate search results. The main aim of this paper is to overcome this drawback through gateway encryption and blind storage, through dynamic block splitting in order to preserve the redistributed data in the cloud storage. Natural Language Processing technique is used to extract keywords by secured multi-keyword search over the cloud data which pre computes the resulting data that the user needs to search and gives accurate and relevant results by without downloading the files contents .Indexing and the privilege preferences were also done prior to enhance the security and decryption of the entire group members file content is also done.
