A SECURE AES BASED DATA DE-DUPLICATION TECHNIQUE USING INVERTED INDEX IN CLOUD COMPUTING

Cloud computing comes throughout focus development of grid computing, virtualization as well as web technologies. Cloud Computing technology that interrelates between applicant and businesses to use web services without an installation. All the web services uses by business and applicant can access the information and files at any computer system having an internet connection. Cloud computing utilizes both central remote servers and internet to manage the data and applications with use of internet technology. With a lot of benefit of cloud such as scalability, accessibility, cost saving world user tend to shift their data to cloud storage. In this paper we are removing duplicate data to save storage space and increase storage speed of network. Hear we applied inverted index technique and tf-idf to identify duplicate data in cloud environment. Once de duplication is achieved system design for secure data transformation in network. Cryptography is common approach to protect the information in Cloud. Encryption algorithm plays a main role in information security system. Security is achieved throw encryption and decryption on data. In this paper we examine secure de duplication technique.. After removal of duplicate data markle hash tree applied.
