A photo of you in public does not violate your privacy.  It has been ruled, time and time again, that the image you present is public and anyone can take a picture of it.<p>BUT, technology allows me to capture far more than the visible spectrum.  Give your clothes probably don&#x27;t consist of lead plates, part of the photos I can detect are from your body and not your clothes.  So using this information, and some recoloring algorithms, I can likely create a decent image of your underlying body.<p>Applying technology allows for more information to be withdrawn from situations where previously that information wasn&#x27;t available.  But due to the need for advanced technology to pick up on the information, most people do not even realize they are leaking it.  (Take private conversation being recorded at a distance by viewing vibrations in objects near where the conversation is happening.)<p>Our technology has outpaced our moral&#x2F;philosophical reasoning and the gap keeps growing.
