IoT and Blockchain-Based Method for Device Identity Verification

The Internet of Things (IoT) is nowadays having outstanding developments in the IT industry and for research purposes. However, it actually experiences security and protection liabilities. Traditional security and protection approaches will, in general, be irrelevant for IoT, principally because of its decentralized geography and the asset imperatives of most of its gadgets. Blockchain that supports the cryptographic money Bitcoin has been as of late used to give security and protection in distributed networks with comparative geographies to IoT. In the IoT, ensuring the validity of the identity of a device accessing the network is the basis of security. A computer network consists of nodes. These nodes are linked through the communication links. The nodes are distributed geographically, and the purpose of the network is to transmit between different types of nodes. These nodes can be personal computers, workstations, sensors, etc. Users carrying wearable devices move from one place to another, and there is a possibility of linking to more than one network. That might raise the anomalies of the information in the network. We aim to remove the anomalies by validating the node with the help of blockchain technology. This paper proposes a system and method for verifying identity using IoT and blockchain technologies. The proposed model will detect anomalies by comparing node traffic profile and behavioral information of the node in the blockchain to the observed node activity.
