Storing private and professional data on the cloud server has a likely chance of losing possession of large size of data. Users convey data using Internet which can be affected by malicious attacks. So, to preserve the privacy of documents, data should be outsourced in encrypted format. In this proposed system, Secure Querying algorithm is used to retrieve top matching results from huge encrypted answer set relevant to user interest. To retrieve the documents of user interest, multi-keyword query has to be fired which will result in accessing the top k ranked documents. Lucene indexing technique has been developed to build an index of keywords from documents. Index will store hashed values of keywords. Blowfish algorithm is used for encryption and decryption of data.
