A Crypto Scheme Using Data Obfuscation of Entity Detection and Replacement for Private Cloud

Abstract

Cloud has been rising, renown, and extremely demanding innovation now a day. Cloud has wide ubiquity with its advanced features, like web access, more stockpiling, easy setup, programmed refreshes, low cost, and resource provisioning on a rent basis. Disregarding many advantages, security is viewed as increasingly significant and drew the consideration of numerous researchers. The information storage is drastically increasing, and there are many occasions that cloud doesn't ensure that data/information that has been placed in the cloud is secured from unauthorized access. Many experts are attempting to guarantee data security in the cloud, yet tragically they don't give satisfactory results. Hence we attempted to propose an effective crypto-scheme with obfuscation and cryptography for unstructured information. The scheme attempts to safeguard the secrecy of information at two phases. In the first phase, it obfuscates the file by supplanting the keywords (obfuscation), and at the subsequent phase, the obfuscated file is encoded by using the conventional RSA (Rivest Shamir Adleman) encryption algorithm for high security. Investigation results show that the proposed mechanism yields great outcomes.
