This delightful story from Pink Tentacle shows how the Japanese cigarette-machine RFID-leveraging face-recognition system is completely fooled by the magazine photo. "The face-recognition machines rely on cameras that scan the purchaser's face for wrinkles, sagging skin and other signs of age. Facial characteristics are compared with a database of more than 100,000 people, and if the purchaser is thought to be well over 20 years old (the legal age), the sale is approved," the story said.
No sooner had IT concocted a system to try and automatically detect an under-age shopper than someone has crafted a remarkably low-tech way to fool it. How low-tech? How about a picture ripped out of a magazine?
