Reality is - no we don't have that legal right. Based on sensitivities, one may wish others hadn't shared certain types of information, but .... this is more about moral perception (ours!!) then of legality. Traumatic perhaps,
but petty to others. Personal information (minor or major) is well-guarded by myself, but what other's know about me by looks or thru acquaintance I can hardly control what they tell to others (or when). It is information by default, it is no secret, not something I can hide. And if it is something that was shared with others and they turn around and 'spill the beans' then it is life's lesson to the person who told the secret, that yes indeedy -- the best way to keep something secret/private/confidential is to keep it to yourself, after all.
