A Survey of Rank Based Search Results over Encrypted Cloud Data

Migration of users into the cloud environment is increased with the high popularity of services provided by the cloud providers. When large number of users outsource their files into the cloud environment privacy becomes the most important issue. In order to assure privacy users encrypt their files before outsourcing it to the cloud server. The efficient searching and effective retrieval of files becomes most complex when the files are stored in the encrypted format. In the previous work Multi- Ranked Search over Encrypted (MRSE) cloud data is implemented to assure privacy enhanced searching mechanism. The ranking mechanism is used to retrieve the most similar files over the encrypted files. However one cannot assure that whether all retrieved results are having similar fields. This work focuses on implementing the rank test method to check the integrity of the rank order (i. e. ) to find out the resulting files are having similar fields or not. Our proposed system is used to retrieve the files with the most similarity values and hence the privacy is improved.
