Wearable technology in the health care sector is evolving into a game-changer instrument for monitoring and improving individual’s well-being. Technologically advanced devices, such as wearable health monitoring devices, fitness trackers, smart rings, and smartwatches, are now considered vital in promoting proactive health care management. However, grave concerns for the privacy of sensitive information emerge as these devices are increasingly integrated into health care environments. Consequently, this chapter critically analyzes the privacy implications of wearable technology in addressing concerns such as data security, consent, and potential misuse of sensitive data. The chapter assesses the interplay between theoretical and ethical underpinnings such as Privacy Calculus Theory, Health Belief Model, Technology Acceptance Model, Kantian ethics, and Utilitarianism. The chapter further assess the utility of such devices in patient’s care, the storage of sensitive data, security breaches, and privacy challenges. Thus, by proposing the best practices to enhance the privacy of data, the chapter seeks to advance the debate on how innovation can be balanced with proper data protection controls so that wearable technology enhances health care without violating personal privacy.
