Abstract: IoT is the boon for industries with capabilities to digitize complete industry process, system, software’s and machineries on one single platform. The capability enables the 360 degree view of the industry. The security concerns is very important while implementing the IoT, since it become crucial for any IoT or IIoT project to implement the security else since IoT application has direct access on internet hence it become more prone to internet attacks hence to avoid we need to have high security which ensures full proof system for this we can have integration of block chain technologies with IoT.

Keywords: IoT, IIoT, Blockchain, Privacy, Security.
