Abstract: Today the need for technology in various aspects of life has risen abruptly, hence leading to the expansion of the internet of things (IoT), but when it comes to IoT data, there is a myriad of issues regarding controlling and auditing it. A lack of measures taken for security can also make IoT vulnerable to a number of threats. To better maintain and minimise these threats, using blockchain can play a significant role by auditing and recording all actions that occur while collecting the data and storing the same in the cloud. Due to the nature of consensus methods in a blockchain system, we introduced the uses of the interplanetary file system wherein the data collected will be stored in them and a hash value will be retrieved which will be sent to the blockchain and recorded. In this paper, we introduced better blockchain-based design for IoT which can show the distributed control of how IoT data is collected, recorded for auditing and stored. Through this system we succeeded in achieving secure sharing of IoT data and proper utilisation of cloud storage resources.

Keywords: blockchain; internet of things; IoT; interplanetary file systems; IPFS.
