Abstract: Cloud computing with new techniques has become a rapid development in modern technologies. As the importance and usage of cloud demand more access, the problems of cloud security face lot more threats. The problems have caused great influences on the development and popularization of cloud computing. The data storage has become an indispensable part in cloud computing. The data could be either numeric or non-numeric. The data to be stored need to be protected with confidentiality measures. The data must be encrypted before deposited into cloud database. The cryptographic techniques play a vital role in enhancing the security. This paper proposes a technique to store the data of numeric and non-numeric type by obfuscation and encryption methods. This paper also proposes the technique to enhance security level. The paper produces minimum time data size and service while uploading into the cloud storage.

Keywords: Cloud Storage, Obfuscation, Encryption, Cryptography, Confidentiality.
