Researchers Develop Biometric Security with Your Personal Stink as a Digital Fingerprint
According to the researchers, there are recognizable patterns to body odor. As part of their study, they found that they could accurately identify a person by their unique odor greater than 85 percent of the time, a value that remained true as body odors changed due to disease, diet, mood swings, and whatever else.
The group is working with Ilia Systems Ltd., which is a Spanish engineering consulting firm. Ilia Systems ran with the research and built a sensor that's capable of detecting volatile elements in body odor. Unfortunately, an 85 percent accuracy rate is about the same as current biometric identifiers, which is considered too low by security professionals.
That said, there's a bit of an upside here. Capturing body odor is easier than other biometric systems -- just walking past a sensor is enough to get a reading. If the researchers can fine tune the technology, there would be a world of possibility and potential applications, such as using it at security checkpoints at airports and the such.
