Multi-factor authentication using gestures

Abstract

This disclosure describes techniques for performing multi-factor authentication (MFA) by utilizing user generated authenticating gestures. The techniques may include establishing and monitoring peer-to-peer communication links between user devices. The techniques may include monitoring channel properties for fluctuations in the channel properties associated with the user generated authenticating gesture passing through signals of the communication links. The techniques may further include comparing a gesture performed by a user to a predefined authenticating gesture. The techniques may include determining a pattern of fluctuations in the channel properties associated with the predefined authenticating gesture. The techniques may include determining a confidence score associated with comparing the gesture performed and the predefined authenticating gesture. The techniques may further include determining a proximity of the user and/or the gesture to the user device. The techniques may further include granting or denying the user based at least in part on the proximity and/or the comparison.
