Remember that time you sat next to someone in a taxi or school and you just cant bare that smell oozing out of them. Its seems the Researchers at the Universidad Politécnica de Madrid are currently developing a new form of biometric authentication based on personal body odor. So that smell could come in handy for these researchers. Three groups of Biometrics, Biosignals and Security (GB2S), hope that it works and could be used used for citizen security at airports security checkpoints and national borders. and in realm of disease detection.
85% smell accuracy
According to the group reports, everyone has their own unique odor that stays the same most of the time. With an accuracy rate of at least 85%, a person’s bouquet can be traced back to them. The researchers have also created a sensor for smell detection, which is sensitive enough to detect volatile elements in body odor.
We have seen Biometrics making a comeback recently like in the the iPhone 5S’ own Touch ID scanner. Are you willing to give up your scent data for security scanning anyway?
