SECURE MULTI- RANKED MULTI-KEYWORD SEARCH FOR MULTIPLE DATA OWNERS IN CLOUD COMPUTING

Abstract

Now days with the advent of cloud computing, it has become increasingly popular for data owners to store their data to public cloud servers while allowing data users to retrieve this data. Users are stores their data in encrypted format on the cloud that’s why unauthorized user cannot access the data. When user wants to access the data they have to get decryption key from user. However, most cloud servers in practice do not just Serve unique owner; instead, they support multiple owners to share the benefits of the cloud computing. This paper, we suggest 1) To keep safe the secrecy 2) Several-owners model search several keywords and Ranked. To make possible cloud servers to execute safe to look omission knowing the real information of both keywords and trapdoors,1)To keep alive the privacy of related scores between keywords and files and rank the search result, we suggest a novel Additive Order and Privacy Preserving Function family.2)dynamic hidden key creation rule and a new data user to establish as genuine rule
