ABSTRACT
The emergence of wearable technology for assessing health data has revolutionized the health sector. Consequently, medical practitioners can now virtually examine the patient's health and provide immediate medications. However, when the security of this equipment is considered, there is a grave hazard. The data is delivered across an open channel, i.e., the internet, from the patient's device to the doctor, and it may be tampered with by intruders. Insurance firms keep a record of their patient's health and subsequently offer appropriate treatments. In case of data tampering, the insurer will consider the conduct fraudulent. As a result, ensuring the system's integrity and granting access only to authorized stakeholders becomes critical. Blockchain has surpassed conventional technologies in terms of guaranteeing security for information held. Motivated by these, this paper has developed a novel approach that uses blockchain technology to transmit a patient's health information to a medical expert. Machine Learning (ML) techniques, K-Nearest Neighbours (KNN), and Logistic Regression (LR) is used to categorize Coronavirus Disease (COVID) positive users and malevolent wearable devices, respectively. The performance of the proposed model is evaluated considering parameters such as accuracy, precision, recall, and F1 score. The proposed model achieves an accuracy of 98.15% for COVID positive detection and 96.78% for malevolent user detection. © 2022 IEEE.
ABSTRACT
CCybersecurity primarily deals with a clear interpretation of various issues related to attacks that occur on digital resources and subsequent remedies therein. While discussing the safety against attacks or crimes against digital resources, the confidentiality, integrity, and availability of such information must be preserved. The COVID-19 pandemic showed us that most human activities such as education, work in various fields, shopping, and communication shifted to online quickly. Therefore, the cybersecurity of computers, networks, and communication systems is critical. Cybersecurity is a challenging and rapidly evolving domain, and it is essential to stay up to date and use the latest protection technologies. This chapter introduces the basic cybersecurity concepts and terminology. The domains and the threats and actors are characterized extensively. Also, this chapter tries to explain the need for cybersecurity in the context of digitalization and increasing Internet usage. A short book outline is also presented. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
