Systems and methods of selection acknowledgement for interfaces promoting obfuscation of user operations

Abstract:

Techniques for obfuscating user selections during user-input of sensitive information, involving displaying targets, such as keys of a virtual keyboard, on a display device, where each target corresponds to one of multiple options. A visual indication for a current user target can move to a first target in response to a first input event at a first time, and the first target can be actuated in response to a second input event for actuation of the current user target at a second time. An obfuscation system is configured to present to a user, at approximately the second time, a discriminatory signal used to confirm actuation of a target. The discriminatory signal includes one of a haptic signal generated by a device in physical contact with the user, an audio signal, and a modified image.
