I'm not sure how they intend to police photos of their daughter as taken by cameras not under their control, or on accounts not under their control, or other information posted about her by friends and family. Given the technologies involved, it would not be terribly hard to infer the daughter's photographs and personal information (name, etc.) and connect the two. There's also the very real possibility that she may not be interested in their idea of her personality and identity by the time she's grown up.
