Abstract

As a smart and effective technology, the Internet of Things (IoT) plays a very important role in today's technology-driven world. This technology refers to a set of computer and technology-driven communications and interactions such as sensors, processing units, software and hardware with other devices and systems, that are connected and linked via the Internet or other communication networks. On the other hand, blockchain is a decentralized and distributed ledger that records transactions on many computers. This structure ensures that no single entity can access the entire chain to commit fraud. Each block in the chain contains a list of transactions, a time stamp and a cryptographic hash of the previous block, so each record created is unchangeable in a secure way. Blockchain technology, as one of the great innovations of the digital world, has been applied in many areas, including cybersecurity. Security is one of the fundamental challenges in the field of IoT, which can be enhanced and improved through blockchain. The purpose of this research is to analyze the solutions to improve security and privacy and to apply it in creating a privacy monitoring system in the Internet of Things based on blockchain technology. Finally, blockchain, with its unique features, can be an important tool in strengthening the security of the IoT against various threats and reducing risks. Using this technology in areas such as data protection, preventing information manipulation, and increasing the security of cloud systems can help reduce threats and improve digital security. Although there are challenges in the path of blockchain adoption and implementation, its benefits, especially in this area, are very significant.
