## Abstract

Systems and methods may provide to prevent user input capture. in one example, the method may include measuring an attribute based on a user's interaction with a user input component of a user input device, generating a user input signature based on the measured attribute, generating an obscuring signature based on the user input signature, and transmitting a control signal, based on the obscuring signature, to obscure a user's input activity and prevent user input capture.
