Abstract: Cloud data have to be encrypted to protect data privacy, before outsourced to the commercial public cloud. The encryption process makes effective data utilization service a very challenging task. Traditional searchable encryption techniques allow users to securely search over encrypted data through keywords. They support only Boolean search and are not yet sufficient to meet the effective data utilization need that is inherently demanded by large number of users and huge amount of data files in cloud. The system facilitates server side ranking without keyword privacy. Search result authentication is provided in the system. The similarity analysis scheme is used to identify the query results under the cloud data storage.

Keywords: Encryption, Searchable encryption technique, Boolean search, Ranked Search
