Authentication and Privacy Preservation in IoT Based Forest Fire Detection by Using Blockchain – A Review

Abstract

Internet of Things (IoT) has garnered a good chunk of limelight with the emerging advancements in technologies. It comprises of heterogeneous devices embedded with sensors, which are able to communicate directly with each other without any human intervention. In this paper, a survey has been done on authentication and privacy in IoT using Blockchain during Forest Fire. The purpose of Blockchain is to design a data structure to construct a distributed ledger of transactions that cannot be tampered by any third party. The blockchain forms by cryptographically linked blocks of transactions. Public-key cryptography is used to sign transactions among users in blockchain technology. It achieves privacy very strongly as it is very difficult to modify or delete blocks of data which are stored in the ledger of blockchain.
