Digital Blindfolding

Blindfolds have been used for centuries to prevent sight, usually during kidnappings but really in any situation where you don't want someone to see something or somebody or someplace.

It's 2018, let's get creative. Imagine a blindfold-like device that went around your head (that also corrected that I-can-kind -of-see-in-that-crack- by-my-nose problem) and, for the most part, allowed regular sight. Using cameras and receiving digital information via wifi, the digital blindfold would see QR codes (or something similar) to automatically "blindfold" computer screens, rooms, faces(think digital camera facial recognition) and would even redact writing on pages (blocking classified information, etc.). Also, through wifi or some other medium, the blindfold would turn into a deaf-fold, using speakers to play white noise when signaled to do so. The nose-fold could be an option for super-secret chef locations, but I do not see this becoming a popular option (sprays vinegar to mask scents?) nor would the hand-fold (a glove-like device that inflates upon signal, depriving the user of any fine motor skills).

To prevent users from hiding codes or otherwise circumventing the system, it would be made with security in mind. The blindfold, using motion sensors, would also generally know where it is, and looks for certain visual markers to verify locations. If it does not see them, it will automatically alarm. The wifi would also require some kind of constant signal so that this cannot be circumvented. If no signal is established and constantly received, white noise will automatically play.
