Abstract: The main aim of project is data owners are motivated to outsource their complex data management systems from local sites to the cloud for great flexibility and economic savings. But for protecting data privacy, sensitive data has to be encrypted before outsourcing, which obsoletes traditional data utilization based on plaintext keyword search. Thus, enabling an encrypted data search service is of paramount importance. Considering the large number of data users and documents in the cloud or server, it is necessary to allow multiple keywords in the search request and return documents in the order of their relevance to these keywords. Related works on searchable encryption focus on single keyword search or Boolean keyword search, and sort the search results. In this process, define and solve the challenging problem of privacy preserving Multi-keyword ranked search over encrypted data. Among various multi keyword semantics, choose the efficient similarity measure of coordinate matching, as many matches as possible, to capture the relevance of data documents to the search query. Provide the data to the users in a secure manner.
Keywords: Two round searchable encryption, searchable symmetric encryption, order preserving encryption, multi keyword search.
