The habit of sharing huge amounts of photos on the social Web is creating many new privacy issues that have been addressed in a multitude of research efforts in the past few years. Most of this research focused on securing users' own photos and managing their online identity in terms of access control. However, implications for other people have not yet received sufficient attention. Photos affect the privacy of all depicted people and those mentioned in metadata. Therefore awareness about photos is a key issue for protecting privacy.
