Cyber Security Risks in Wearable Devices

Abstract

The growing popularity of wearable devices, particularly for medical and fitness applications, has increased reliance on these technologies for tracking biometric data. These devices typically transmit data in multiple stages, beginning with Bluetooth Low Energy (BLE) connectivity, followed by transmission to internet-enabled devices, and ultimately to cloud storage. Each communication step introduces potential cybersecurity vulnerabilities. Understanding the functionality of wearable devices, the data transmission process, and the associated cyber risks, is crucial to safeguarding users against cyberattacks. This paper explores the types of sensors used in wearables, the data transmission workflow, and the cybersecurity challenges involved. It also discusses potential preventative measures to mitigate these risks.
