Abstract:
A wearable device includes a first sensor configured to detect a first biosignal generated in response to a gesture performed by a user, and a second sensor configured to detect a second biosignal of the user. The device further includes a memory configured to store, with respect to at least one user, information of the first biosignal and the second biosignal, and a processor configured to initiate user authentication based on a result of determining whether the detected first biosignal corresponds to the stored information, and authenticate the user by comparing the detected second biosignal to the stored information.
