Blockchain Technology Based Privacy Protection Scheme for Large-Scale Distributed Systems

Abstract

The cloud and mobile cloud deployment in large scale distributed systems offer excellent service that enhances both individual and organizational effectiveness. These cloud and blockchain based systems can provide resources at a very cheap cost since they are built on independent nodes except for any special centralized monitoring and controlling. As a result, the growth of mobile services and apps is unpredictable. Data-driven apps stand out among them in terms of popularities or revenue generation. However, the data-intensive applications have additional issues such as storage, big data filtering, and the critical tasks of securing confidential or sensitive data. In this study, a blockchain model using cloudlet concept is proposed. This model is then used in mobile cloud computing. The simulation of the proposed system is carried out in a mobile cloud computing simulator. According to the experimental analysis and latency result, the blockchain approach outperforms the conventional cloud models by up to 90%,
