Security against Ransomware Attack in Medical Healthcare Records Using Blockchain Technology

As a matter of fact, Ransomware Attack is considered an essential threat to cyber security. This type of intimidation often causes an immense loss. For instance, the electronic records of medical healthcare have been one of the main targets of Ransomware attacks. This could be attributed to the fact that sensitive data belongs to patients. In this paper, we use Blockchain technology to be an appropriate solution for Ransomware attacks. It is believed that the procedures taken by this technology, specifically in the health sector, will create a defense wall that would protect patients' data. We mainly intend in this paper to enhance Medical Healthcare Records (MHR)-based healthcare through the utilization of the Ethereum Network to treat and investigate unusual transactions. In order to achieve this objective, an astute arrangement has been developed so that MHR will be sent via the Ethereum Blockchain network. Thus, MHRs are protected from any Ransomware attacks, especially from those attackers who pretend to be patients and attempt to penetrate the web through their claimed records. Finally, the recommended system could be evaluated through the metrics utilized for evaluating performance, including the cost that reduced the cost to 855304 Wei and the execution time for raising patient records on Ethereum Network compared to the standard system by 60%, immutability, data storage, and estimated time required by attackers to attack the block.
