The Human Key: Identification and Authentication in Wearable Devices Using Gait

With the advent of wearable devices and the commonality of on-body monitoring devices, a future is anticipated in which the body-area networks will become commonplace in daily life. It is envisioned that the whole process will be automated wherein a user wearing such a device automatically enables the associated security mechanism and establishes communication between that user and her surroundings. This article addresses a technique to identify the wearer of the device and proposes an encryption scheme for secure communication, allowing for identification and authentication before establishing communication. It suggests using gait as a metric for identity association using wearable sensors.
