I proposed something like this for my graphic design thesis about 10+ years ago, though it was meant more as a warning against all the social media apps that were coming out at the time (foursquare, facebook, and others). People were posting pics of themselves all over and you could grab a ton of info just from a person’s picture. To prove my point I picked a random person based on a photo they posted and found as much info as I could. The pitch was that I would present it completely straight, as if it was a legitimate service, but I wanted it to come off creepy as fuck, as a sort of warning against the out-of-control posting that people were doing. It was going to be a sort of “dating” service where you could take a picture of somebody and instantly get all the information available on the internet about them, more a stalking app than anything, but same basic idea as this. Apparently I should’ve started up my own company.
