Abstract

Today outsourcing sensitive data to the cloud server is a major concern. Encrypting this data is one such solution to the problem which hides the actual data from the server. Even, the index is encrypted for further protection. In most of the data privacy algorithms, the index is constructed on the original file and then both index and document are encrypted. However, leakage of the secret key allows the cloud server to decrypt and figure out the data. This motivated us to propose a method based on the encryption of every word in a file. This method achieves its efficiency by applying a new idea where index is constructed on these encrypted words. The algorithm further ensures the security by encrypting the search query passed by the subscriber. Hence, the search is only on encrypted words in the index. The cloud server is oblivious of the data in all ways
