This paper explains how an effective, still privacy preserving fuzzy keyword search in the domain of cloud based computing can be done. The paper discusses the problem of extracting the file from a cloud server using minimal amount of resources. Whenever a user wants to find a file on the cloud server, he/she has to browse through a lot of files. It results in complete wastage of bandwidth and most important time. One of the easier and efficient way to do this is to retrieve the files through keyword-based search technique. By this, they won't have to retrieve files that are encrypted and doing such a thing would be totally impractical in case of cloud computing. So, the keyword based search allows the users to retrieve the files of their interest. Such a technique is applied widely in plain text searching scenarios, like search engines. But, data encryption prove to be a restriction to user's ability as it does not allow user to perform keyword search, making a plain-text-search method useless for cloud computing. [1] An effective way is formalized for resolving the problem of performing an effective-keyword-search on the encrypted data stored in a cloud and yet, maintain the privacy of the keywords.
