In this paper, the authors detail about various methods prevailing in literature for effective query service mechanisms in cloud. A privacy indexing for range query is discussed in detail. Methods for deriving privacy information from randomized data are portrayed. Geometric data perturbation for privacy preserving outsourced data mining and attack resilient geometric data perturbation private information retrieval and dynamic authenticated index structures for outsourced databases are examined. Various attacks view of distance preserving maps for privacy preserving data mining and privacy preserving index for range queries are semantically evaluated.
