A Secure and Scalable IoT Data Management System based on Blockchain

Abstract

Today’s market is home to an increasing number of Internet of Things devices. We often talk about gadgets like the Amazon Echo, Chromecast Mini, watches, and others. Since the majority of these systems employ a centralized architectural strategy, a single entity or organization often controls the majority of the online data. Although these firms have rigorous regulations against data abuse and illegal change, the fact that they have the authority to do so must be taken into account. Blockchains are decentralized, so if someone attempts to alter data on one blockchain, other blockchains will stay intact and the hashes of that particular blockchain will no not match, invalid that particular blockchain and protecting users’ data. Running a complete Chain server on all connected systems, especially low power or data storage devices, is challenging due to the extensive resource needs. In just this manuscript, we developed a modular approach blockchain based, as well as a centralized cloud architecture alternative that is a traditional user structure with a fundamental Blockchain at power or ability, as well as a solidity-written smart contract application on the Ethereum platform. By using Blockchain characteristics, we build this framework and show how it avoids data exploitation without requiring all IoT technologies to run a Chain node. From the standpoint of the user, it will show up to be the same as a typical web app, and from the standpoint of the developer, the reference implementation application will have equivalent software design to interactive web apps, enabling for an interesting experience for both centralized and decentralized methods while still upholding the trust of decentralization.
