An Efficient and Trusted Data Storage Process for Cloud Computing

Abstract: In recent years due to attractive features of cloud computing, users are storing large amount of data on cloud storage, these data may be users personal or secret. Users remotely store their personal or secret information on cloud storage and enjoy best features of cloud applications without burden on local hardware and software management. After storing data on cloud storage users can access their data by very thin clients. But there is a drawback o f outsourcing data on cloud storage is data security risks because users has no control over outsourced data even users are unknown about location of their data. So, in this situation, achieving data confidentialit y on outsourced data is an open challenge for researchers. Today some systems are available by using that we can store and retrieve encrypted data but if we have large amount of data to store on cloud than it is difficult to retrieve them efficiently. Anot her problem is to store and manage encryption keys efficiently. To solve the data confidentiality and key management problems together we are using ranking function on inverted indexes and advanced shamir’s secret sharing algorith m.
