An enhanced secure, robust and efficient crypto scheme for ensuring data privacy in public cloud using obfuscation & encryption

Cloud has been emerging, popular and very demanding technology now a day. Cloud has got wide popularity with its sophisticated features. The primary features of cloud include internet access, more storage, easy setup, automatic updates, and low cost and resource provisioning based on “pay as you go” policy. In spite of advantages, security is considered to be more important and drew the attention of many researchers because it is not guaranteed in an open cloud. The data storage is becoming an indispensable measurement in cloud and most of the times cloud does not guarantee that data that has been stored is secured from illegitimate access. Many researchers are working to ensure data security in the cloud but unfortunately they do not provide adequate security to data. This paper is aiming to propose a secure hybrid scheme with obfuscation and cryptography to ensure the privacy of data shared in public cloud. Experimental results show that the proposed scheme yields good results. © 2019 International Information and Engineering Technology Association. All rights reserved.
