Keywords: Concept Search | Confidential data | Cloud computing | Keyword Search | Order-preserving mapping | Ranked Search

In this paper we define and solve the effective yet secure ranked keyword search over encrypted cloud data. We used order preserving symmetric encryption to protect the cloud data. Even though there are lots of searching techniques available, they are not giving efficient search results. For example the search results returned 40 records and in those 30 records are relevant and the remaining 10 records result contains irrelevant data. This paper mainly focuses on searching methods which will improve the efficiency of searching. We used both keyword search and concept based search methods in order to retrieve the relevance search criteria. This method will retrieve the documents based on broader conceptual entities, which will improve the efficiency of ranked keyword search.
