Opportunistic Multi-Modal User Authentication for Health-Tracking IoT Wearables

no code implementations28 Sep 2021 Alexa Muratyan, William Cheung, Sayanton V. Dibbo, Sudip Vhaduri

While most of these external authentication techniques suffer from multiple limitations, including recall burden, human errors, or biases, researchers have started using various physiological and behavioral data, such as gait and heart rate, collected by the wearables to authenticate a wearable user implicitly with a limited accuracy due to sensing and computing constraints of wearables.
