Authentication concealment and alignment systems

A method for controlling a user monitoring apparatus for identifying a user of a vehicle, the method comprising:

• capturing image data depicting identifying information of the user in a field of view;
• detecting an alignment condition;
• in response to the alignment condition, activating an emitter to output an alignment emission through a selectively transmissive privacy device;
• and
• illuminating alignment information with the alignment emission on a display panel through the selectively transmissive privacy device, wherein the alignment information visually indicates an alignment of a portion of the user within the field of view.

A user monitoring apparatus for identifying a user of a vehicle comprising:

• a scanning apparatus configured to capture identifying information of the user in a field of view;
• a panel comprising a display portion;
• and
• a feedback apparatus comprising comprises at least one emitter configured to emit an alignment emission through a selectively transmissive privacy device, the feedback apparatus disposed behind the panel and configured to communicate alignment information visually indicating an alignment of the facial feature within the field of view of the scanning apparatus, wherein the selectively transmissive privacy device limits a viewing angle of the alignment information visible through display portion of the panel, wherein the viewing angle is within or commensurate to the field of view of the scanning apparatus.
