If this new patent filed by Kodak becomes a reality, it doesn't matter how many plastic surgeries and facelifts you get... you can't lie about your age no more! The camera conglomerate is adapting the technology used to automatically correct flash-induced "red-eye" in digital images to determine a person's age. A patent filed by researchers from the company's labs in Rochester, New York, suggests the technique could provide a quick and easy way to check someone's date of birth preventing underage drinking and the likes.

So how would this work? The "red-eye" takes care of all that. Red-eye is the effect seen when a person's open pupils allow a camera's flash light to be reflected off their retinas. Correction software analyses a picture, looking for a pair of red dots in the centre of a face, and automatically dulls them to remove the effect. And according to Kodak researchers, as a person gets older, their pupils have greater difficulty widening to cope with dim light. The good news for those who constantly lie about their age, this age-detecting camera ain't happening in the near future...it may take a while.
