Recent years have witnessed a widespread interest in healthcare issues and the search for faster and safer service for patients. Electronic health record was established to provide advanced health services. Researchers seek to provide permanent and simplified ways to monitor patients remotely using remote patient monitors. One of these methods is the use of Internet of Things (IoT) devices, where the healthcare provider can monitor the patient remotely. However, with the current centralized electronic patient record system and increase in number of IoT devices, security and privacy issues have arisen, as some patients may not want to disclose their data, in addition to particular concerns or risks that affect the patient’s life. To reduce these issues, several studies have presented the use of blockchain technology as a trustworthy network of solutions to ensure patient information security and secure the transfer of IoT devices’ data. In this regard, this research is an attempt to present a new framework that facilitates the storage and transfer of patient data in the blockchain by merging the electronic health record and remote patient monitoring techniques into a single framework using Django. This framework allows the transfer of data from IoT devices to multiple peers, making use of the smart contract provided by the Ethereum platform.

During the last two decades, all fields, including the oil sector, depended mainly on technological progress to keep pace with the developments in this field. This technological progress was accompanied by an increase in hacking attempts. Cyber-attacks are defined as the hacking of a computer by a person or group of people over the Internet, causing a lot of damage, especially to devices and equipment that depend on the Internet; This leads to substantial financial losses. Therefore, it is very important to understand these attacks and try to overcome them.  In the oil sector, cyber-attacks can be scanned in three areas (upstream, midstream, and downstream).  This paper discusses how to secure cyber security for the oil sector by making plans for Internal and external cybersecurity by creating and securing separate loops by using blockchain technology and creating a smart contract for each loop to protect it information. As well as using the simulation and control system to increase the effectiveness of cyber security, and after this survey process. This paper aims to classify the cyber-attacks that affect the oil and gas sectors. Create a strong system against any type of cyber-attack, and thus provide higher protection for oil and gas companies and equipment through the work of special programs to protect systems and equipment from hacking.
