摘要：Cloud Computing becomes prevalent, sensitive information are being increasingly centralized into thecloud. For the protection of data privacy, sensitive data has to be encrypted before outsourcing, which makes effectivedata utilization a very challenging task. Although traditional searchable encryption schemes allow users to securelysearch over encrypted data through keywords, without capturing any relevance of data files. Ranked search greatlyenhances system usability by enabling search result relevance ranking instead of sending undifferentiated results, andfurther ensures the file retrieval accuracy. The statistical measure approach, i.e. relevance score, from informationretrieval to build a secure searchable index. . In proposed system, stemming and Synonym clustering is applied on thescore calculation of each keyword in the file collection, it increase the score value and it help to retrieve more relevantfiles.
