A Novel Technique for Relevant Data Retrieval from a Set of Encrypted Documents

Data owners can outsource their data in cloud servers rather than purchasing their own storage devices. The Amount of trust provided by the third party cloud server will threaten security of our data as anyone who has access to the data server can view our sensitive information. Solution is to encrypt the data before outsourcing it. Searching on encrypted domain is a prominent research problem. Usually a search request will prompt the server to upload the entire file to the user and user has to decrypt the whole data at its local host. This is not an efficient solution for remote storage as it needs decrypting the entire data for retrieving a small part from it. Searchable encryption algorithms can be used to search on the cipher text. When a search request arrives then the cloud server attempts to search on the encrypted domain making a simpler solution. This paper introduces a new technique to search on the encrypted domain.
