Litchfield et al. [ 44 ] have discussed issues regarding healthcare data security and privacy and suggested blockchain to overcome these issues besides doing a survey on healthcare issues. Vora et al. [ 45 ] discussed breaching of patient information such as name, address etc. on a regular basis. They proposed blockchain mechanism to handle electronic health records. The main goal of their paper was to analyze their system performance to see how their proposed framework handles the needs of a patient, doctors and third parties.

Electronics 2020 , 9 , 94 4 of 23 Zhang et al. [ 46 ] wrote a book chapter proposal where they have discussed di ff erent use cases of healthcare blockchain. They have highlighted the importance of the blockchain-based system for healthcare and how blockchain technology provides e ff ective healthcare design. Siyal et al. [ 47 ] discussed how blockchain technology and smart contracts are beneficial for the healthcare sector by streamlining the overall process. In their work, they have stated that managing healthcare record are crucial and blockchain has the potential to reduce the loss and to prevent fabrication of data by securing the information on the ledger. Jamil et al. discussed the issues regarding drug regulations and how to standardized drugs using blockchain. In their work, they have highlighted the di ffi culties to detect falsified drugs and proposed blockchain as a way to detect counterfeits [ 48 ]. Lee and Yang worked on the fingernail analysis management system using blockchain and microscopy sensor. Human nails are very unique and reflects the physiological nature of the human being. In their work, they have used microscopic sensors to capture the nail images and used image pre-processing techniques to get the clear images. A deep neural network was utilized for performance monitoring of a feature extraction algorithm. Blockchain technology was used as a means to protect user data and provide security and privacy so any change in the system can be tracked and recorded via the ledger [ 49 ]. Agbo et al. [ 50 ] did a systematic review of current research of blockchain applications for healthcare. They have selected 65 papers to address their research question. Their study shows that blockchain could be a potential technology for di ff erent healthcare use cases which includes drugs supply chain, biomedical research, managing electronic healthcare records. However, they have also analyzed the fact that there is still needs to develop more understanding of blockchain technology and how it could be a best fit for di ff erent healthcare related challenges. Innovation has been slowed down in healthcare because of ine ffi ciencies and heavy regulations. Azaria et al. discussed these regulation issues causing ine ffi ciencies in EMR system [ 51 ]. They have proposed blockchain based solution known as MedRec for managing huge amount of medical data in EMR system. They have demonstrated a unique and innovative approach for accessing of healthcare records, which provides fair audit access log system. MedRec enabled patients and doctors to share

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
