As cloud computing has become prevalent data owners tend to outsource their sensitive information to the cloud. The data have to be encrypted before outsourcing to protect the data privacy. Related works on searchable encryption support either single keyword search or Boolean keyword search which focuses on exact keyword. It does not support minor typos or format inconsistencies. Sorting of results is also rare. In this paper, the authors propose secure fuzzy multi keyword ranked search over encrypted cloud data. This scheme allows multiple keywords in the search request and returns the documents in the order of their relevance to these keywords.
