Blockchain Application in Healthcare Industry: Attacks and Countermeasures

Blockchain technology is a collection of records called blocks, and it is characterized by several features including transparency, which means that everyone in the network can view all information stored in the blockchain, and blockchain technology is also decentralized, meaning that there is no authority within it. This technology is used in many areas, including digital identities. Digital auctions as well as cryptocurrency and so on. Blockchain technology plays a large role in healthcare in terms of its many services, as it helps healthcare researchers decode the genetic code and securely transmit patient medical records, and it also manages the drug supply chain. All Blockchain-based systems are exposed to various attacks by attackers, which threatens the security of information and data stored on blockchain systems, and among these systems are blockchain-based healthcare systems. This paper focuses on the recent attacks and countermeasures of blockchain technology in the healthcare field. Several expected attacks are discussed and countermeasures that can be used to prevent or reduce the risk of these attacks are mentioned.
