Technology seen in science fiction movies is more and more commonly appearing in the real world.   The target advertising that makes use of the scanning technology depicted in the movie  "Minority Report",  is gradually becoming more widespread.   In the UK,  this kind of advertising is about to be used in marketing.   They make use of facial recognition technology to scan pedestrians and then decide what type they will use.   I think apart from being interesting,  privacy issues should also be properly addressed.
