We increasingly live in a world of real-time marketing. Soon you'll even be able to turn your face into a customer loyalty card. That's essentially the premise behind a new service called Facedeals, "an automated check-in system using passive facial recognition to notify you of in-store deals that are customized just for you." But as Greg Beato reports, there's also a growing market for privacy, such as encryption apps that hide your email and texts. As old-fashioned anonymity grows increasingly difficult to attain, at least without detaching yourself from the culture at large, Beato writes, the fetish value of privacy is likely to flourish.
