Abstract
A smart city ensures quality maintenance in diverse sectors, namely citizen safety, security, healthcare, transportation, and energy. Besides, data privacy and security have become an uprising concern for Electronic Health Records (EHR) in smart cities. This is because the EHR platforms are constantly getting cyber threats from cybercriminals. On the other hand, health insurance companies offer certain specific policies that require the association of patients' financial data with EHRs. Thus, additional security concern arises as fraudulent entities can alter these insurance policies. An extra challenge is triggered as patients need to validate their identities separately while communicating with different smart healthcare entities. This is because these healthcare facilities and insurance companies ought to ensure authenticity before offering any service for an individual. Hence, we have implemented a blockchain framework to safeguard patients' personal information and insurance policy. In this paper, we propose a solution for the healthcare system that provides data privacy and transparency. Furthermore, in the proposed system, insurance policies are incorporated in blockchain via the Ethereum platform and data privacy is shielded with cryptographic tools.

Summary
I N order to improve the efficiency of fitness, travel, resources, education, and public infrastructure, smart cities use numerous innovations, resulting in a upper level of comfort for their citizens [7]. The main focus of developing a smart city is to improve the quality of life of its citizens. EHR is a collection of a patient’s health history in a digital format. The doctor has the information of the patients visiting him/her. Doctors require the patient sign a document confirming their understanding of their privacy policy, but they are not concerned about maintaining these data [8]. EHR solved the issue as its a digital format of patient’s medical history. EHR, patients’ personal informations, and social security numbers are highly valuable, and cyber attackers sell these to counterfeiter on the open market for profit [21].
