> Am I breaching the privacy of the people I saw at the grocery store yesterday because I can remember what their faces look like? You remembering faces is fine as it doesn't allow you to share with others what your mind "recorded". The amount of detail is questionable and you'd probably not remember everyone and everything but what strikes you as unusual/suspect etc.. Second, since you're not a machine you wouldn't be able to run algorithms on the data you recorded, you'd make a few inferences here and there and that is normal but you wouldn't be able to study the psychology of every customer that entered your store and use it against them.
