Application design for privacy and security in healthcare
Electronic health records (EHRs) were seen as a panacea for managing all medical related data about the patient. The goal was to identify the siloed data fragmented across various healthcare providers and combine it in a uniform way in order to provide the best possible diagnostics and make it easy for the practitioners to gather and study patient's medical data. However, despite decades into development, such record systems are still long ways off in terms of practical implementation. They have been dogged by various shortcomings and above all concerns regarding potential loopholes in the privacy and security of patient data. Given the poor track record of the industry when it comes to preventing illicit access and sharing of data, there is an ever-growing impetus to stanch the consistent violation of the privacy of an individual's personal information by illegitimate parties. In this chapter, we aim to develop an understanding of an EHR system, identify associated shortcomings, and the requirements that it is supposed to fulfil. We also present various proposed implementations that show promise in the development of a safe, secure, and unified EHR system. In the last section, we discuss the potential of blockchains and how they have the goods to deliver a perfect EHR system.
