Not everyone wants to be famous for 15 minutes.
From Times Online:
By wearing a specially designed electronic badge that jams electronic cameras, they will be able to prevent photographers from taking unwanted pictures.
The “privacy protection system” being developed by Hewlett-Packard will allow the publicity-shy to transmit an infrared signal to any nearby compatible camera. Once activated, the camera’s software will automatically blur beyond recognition the face of anybody wearing the badge, New Scientist magazine reports.
(Sites like this would be one reason why such a feature would be desirable.)
And just to cover all bases, HP is also developing technology that will allow you to take a picture without being detected.
