Unknown Face
Your face will be indexed. Be sure. Does it make you shudder? Ah-ah-ah. It is not sci-fi. Something so extended as Picasa is already capable to search and sort photos on face value. Yes, it is a great chance to populate ontologies 
but it gives the machines more power to know everything about you.
Face-finding has made huge improvements recent years. Researchers at Carnegie Mellon University have developed a system that can recognize faces in low resolution videos.
Freedom, privacy, information access… just think that when you upload something to the web you are providing more information than you thought.
