Recently, Google added new functionality to the Google Arts & Culture app that allows users to snap a selfie and find artwork from around the world that resembles the user. The app very quickly rose to the top of the charts as users around the United States took plenty of photos. Almost everywhere around the United States at least. Illinois and a few other states have laws that prohibit the collection or use of biometric (iris, fingerprint, etc.) data by businesses except under certain circumstances. The Google Arts & Culture app uses biometric data to compare a user’s image to the Mona Lisa (or any other portrait).
