Removal of duplicate data from encrypted cloud storage

Cloud computing plays vital role in data storage. In cloud computing data are stored through online, so that it is a trivial process to maintain its privacy and security. There are many algorithms are available to provide these services. Even though it is hard to identity and removes duplicate data. In this paper, Message locked encryption algorithm is discussed about removal of duplicate data in a storage. But this method fails to provide security. To overcome this method, we propose we propose a scheme called proxy re-encryption which provides high security and ease of maintenance. And then both the algorithms are simulated and the result given.
