Billboards that look back 2 Jun 2008

From CNET News:

"[Entrepreneurs] are equipping billboards with tiny cameras that gather details about passers-by -- [including] their gender, approximate age, and how long they looked at the billboard. These details are transmitted to a central database.

"Behind the technology are small start-ups that say they are not storing actual images of the passers-by, so privacy should not be a concern. The cameras, they say, use software to determine that a person is standing in front of a billboard, then analyze facial features (like cheekbone height and the distance between the nose and the chin) to judge the person's gender and age. So far the companies are not using race as a parameter, but they say that they can and will soon."

Scary stuff!
