Privacy Preserving Multi-Keyword Ranked Search Over Secured Cloud Data

computer engineering

As the cloud technology is getting more and more popular day by day users are inspired to store their data on cloud. The clouds like amazon azure are getting more and more popular day by day. Clouds provide resilience and reasonable in price. But for privacy preserved it is necessary to encrypt that file before upload on cloud. Since there so many files are uploaded by various users on cloud so it is required to provide facility of searching not only searching but the multi keyword search with the proper ranking. Currently the search facilities which are provided are mostly a single keyword search or a Boolean search. So we think it is necessary to provide multi keyword ranked search to enhance the experience of user. From many of the algorithm, we used coordinate matching for getting more and more matches as possible and to give more flexibility towards users we also provide backup facility.
