Patent attributes
Systems and methods for performing multi-factor authentication using a smart ring are disclosed. An exemplary method includes performing a first authentication operation by: collecting, by sensors, gestural data representing a candidate gesture corresponding to ring movement; comparing the candidate gesture to an authentication gesture for a known user; when the candidate gesture matches the authentication gesture, generating a first signal indicating that a particular user has been identified and authenticated as the known user; and transmitting the first signal to a second device, wherein the second device controls access to a resource. The method also includes performing a second authentication operation by detecting contact between the ring and an external component; and generating and transmitting a second signal in response to detecting the contact, and when the second device receives the first and the second signals, causing the second device to grant the particular user access to the resource.
