Trends and Challenges of Block Chain in Electronic Health Record System

The exponential growth in the quantity of digital information is accumulated in electronic health records. Electronic health records are now booming in providing patients, doctors and health care management in examining the profiles of patients and giving proper treatment when emergency. Thus, it has also led to huge impetus on exploiting the EHR to aid clinical decision support systems. The enormous increase of data breach, criminal deception, unjustifiable claiming and thefts in patients' data make difficult for health care systems to provide quality oriented care to patients by contradict it needs an effective authentication mechanisms and secured data storage. Blockchain technology recently have immensely attracting the healthcare industries with its storage methods, distributed and immutability nature of securing the data. There is a growing research body in this direction to develop useful insights for secured EHR. The main objective of the research is to identify various methods, frameworks, regulations and perform an extensive review. Recent advances in deep learning techniques with blockchain technology have contributed to secure applications using EHR. Towards this, overview of recent advancements and techniques employed to analyze EHR data securely is introduced. Reviews of the literature discuss the challenges of different approaches. In addition to that effective cryptographic authentication mechanisms that aid future research improvements and trigger innovative applications in healthcare will be highly beneficial for deploying an improved block chain security framework.
