Application of cryptography in enhancing privacy of personal data in medical services

Abstract

Computer security began decades ago in an era where there was no internet or network to take into consideration. During this era, the top priority was to protect data based on physical measures. Furthermore, security largely focused on preventing individuals with enough knowledge about how to operate an electronic device. Over the years, the security of data has greatly evolved with the evolution in technology. The scope of data security has also enlarged making it a sensitive area in contemporary society. This paper analyses cryptography in securing the privacy of personal data transmission in medical services. It focuses on the evolution of these strategy, the need for cryptography, and some of the given instances that cryptography is applied in medical services. Additionally, this paper provides code-based examples of cryptography with a real-time demonstration using an Integrated Development Environment (IDE).
