Electronic Health Records management in healthcare system is one of the perplexing systems which should be secured, decentralized, and authentic, and any minute error in these systems can be all around expensive both monetarily and socially. The data residing in existing EHR systems is centralized in healthcare institutions or hospitals in databases on servers inside the institutions or hospitals. These systems may suffer from different issues like no distributed access of EHRs, interoperability issues like handling different formats of data and their exchange, security and recovery issues like any loophole in the system can lead to cyber-attacks. The blockchain innovation empowers the usage of profoundly secure and protection saving decentralized frameworks where exchanges are not under the influence of any outsider associations. Utilizing the blockchain innovation information put in a fixed compartment called block conveyed over the system in an undeniable and mutable way. Data security and protection are improved by the blockchain innovation in which information are scrambled and disseminated over the whole system. This paper provides an insight into the existing health record management systems and their challenges. Also this paper introduces blockchain technology, its architecture, and impacts in the healthcare industry. In addition, a model for the generation of the unique identity of the patient as Unique Patient Identifier (UPID) is proposed to have the single patient identification record for universal access using blockchain technology. |
