Wearable technology allows for consumers to record their healthcare data for either personal or clinical use via portable devices. As advancements in this technology continue to rise, the use of these devices has become more widespread. In this paper, we examine the significant security and privacy features of three health tracker devices: Fitbit, Jawbone and Google Glass. We also analyze the devices\u27 strength and how the devices communicate via its Bluetooth pairing process with mobile devices. We explore possible malicious attacks through Bluetooth networking. The outcomes of this analysis illustrate how these devices allow third parties to access sensitive information, such as the device exact location, which causes the potential privacy breach for users. We analyze and compare how unauthorized parties may access the user data and the challenges to secure user data on three wearable devices (Fitbit, Jawbone, and Google Glass) security vulnerability and attack type
