Acesso e compartilhamento de dados de saúde em blockchain usando smart contracts

Abstract

The advancement of digital technology has played an essential role in the field of healthcare. The secure and efficient exchange of medical information is of significant importance to ensure effective treatments in healthcare management. Considering the recent advancements in the healthcare sector with the Internet of Medical Things, the introduction of wearable and, more recently, ingestible devices, along with the traditional Electronic Health Records (EHR), it is necessary to manage these data to ensure that only authorized individuals have access. There is a challenge of interoperability of medical data among various healthcare institutions, and ensuring the secure transmission of these data has become a priority due to cyberattacks carried out by hackers. This information is highly confidential and valuable in the market, susceptible to extortion. Blockchain emerges as a potential revolution in the healthcare industry, offering features such as data privacy and transparency. To control the information generated by various medical devices and the diverse healthcare data from different sources, such as imaging exams, laboratory tests, etc., we propose the use of Blockchain-based Smart Contracts for secure access and sharing of data, enabling patients to control who can access their medical data and under what circumstances. The system will utilize the sCrypt development platform, a framework for developing blockchain applications based on the Bitcoin protocol with the creation of Smart Contracts. An application that will record and store all events on the blockchain, with an immutable history and global access to medical information from anywhere at any time.
