New biometric technique to identify people by their body odor

A new biometric technique is underway to allow people to be identified by their body odor.

Researchers at the UPM along with the IlA-a Sistemas company have found that there are recognizable patterns of each person's body odor that remain steady, which leads the way to improve personal identification that is less aggressive than other biometric techniques being used today.

Several biometric techniques like the iris and fingerprint have a low error rate, but using biometric techniques based on a person's physical features would increase safety effectiveness.

The research has used a system developed by the IlA- Sistemas SL company that has a high sensitivity to detect volatile elements present in body odor.
