Abstract

To resolve the privacy, consistency, and scalability based on missing link, blockchain technology is an involvement in the Internet of Things (IoT). It can be used in tracking billions of connected devices, enable the processing of transactions and coordination between devices that allow for significant savings to IoT industry manufacturers. Blockchain technique has provided with decentralized security and privacy and also accomplished essential energy, computational overhead, and delay. These are not a suitable for most resource-constrict IoT devices. This approach of decentralization would create an additional network for devices to run on and eliminate the single points of breakdown. This study describes block chain technology using cryptographic algorithm based on encryption and decryption has built a user database with highly secure and privacy and this paper illustrate about the security and privacy preserving based on block chain in IoT.
