Management of Encrypted Data and De-Duplication of Big Data in Cloud Computing

Cloud computing is the accessibility of computer resources which includes storing of data and power to compute the data, when there is a demand of it for several applications. It is used to represent the data centers to users in the end over the Internet. The user cannot directly manage it actively. The challenging problem is the integrity of outsourced data. The encryption and decryption of data must be secure to overcome this problem. Here we use MD5 encryption algorithm to secure the outsourced data. Data replication is avoided by using de-duplication technique; thus the efficiency of memory storage is enhanced and time for processing is minimized.
