Cloud computing promises the capability of sharing encrypted data with different users through public cloud storage and it may have the security issues over the data confidentiality and authentication access control. The blind storage allows a client to store a set of files on a remote server that the server does not familiar with the files that are stored in it. In this paper, the authors develop a searchable encryption technique for multi-keyword ranked search over the data storage in the context of cloud. The efficient multi-keyword ranked scheme can return the search resultant based on the ranked search with efficient accuracy by using enhanced K-nearest neighbor technique.
