The new frontier of biometric access: the body odor

The Universidad Polit├ęcnica de Madrid has added to the biometric recognition tools already on the market, another ingredient: the body odor. Identification parameter that, according to the researchers may soon be used for a reliable recognition through personal characteristics and biological properties. So we’ll be able to filter people based on the scent they emit.

The challenge is identify and isolate, in the safest way, the odorous signature that characterized each of us. In fact, it isn’t the single odor, but the pattern of odors that characterizes us in the course of life. This smell remains stable and it’s the unmistakable signature that tomorrow will help us to embark on an airplane or go into the bank. Today the control of our identity, in many airports or border crossings, is based on the physical resemblance to the picture of an identity card or a passport. Limit that can be easily crossed. In the future will be increasingly difficult to tamper the new electronic documents, the use of biometric techniques that do leverage on the physical characteristics of a person will increase the levels of safety. On the other hand from many years, the accesses through biometric recognition make the public and private places more confident, drastically raising the level of protection.

At the moment the rate of recognition of the new system is estimated around 85%, in addition the odor of the body can vary over time and the sensors available are not yet very precise. So the new technology isn’t comparable to the reliability of biometric systems as the most advanced iris scanning, the reading of the fingerprint or the facial recognition. We’ll have to wait a little longer to see electronic noses in the areas of access.
