"Sniffing Out Your Identity With Breath Biometrics"

In collaboration with the University of Tokyo, researchers from Kyushu University's Institute for Materials Chemistry and Engineering have developed an olfactory sensor for biometric authentication using breath. The artificial 'nose' they developed can identify individuals based on their breath. The olfactory sensor system, which is equipped with a 16-channel sensor array capable of detecting various compounds found in a person's breath, has the potential to become another option in the biometric security toolkit. The 'artificial nose,' when combined with Machine Learning (ML), successfully authenticated up to 20 individuals with an average accuracy of more than 97 percent. Biometric authentication is a way to protect valuable assets in this age of information and technology. There is various biometrics that machines can use to identify individuals, ranging from fingerprints, palm prints, voices, and faces to the less common options of ear acoustics and finger veins. These techniques rely on each individual's physical uniqueness, but they are not foolproof as physical characteristics can be copied or damaged by injury. Therefore, human scent has been emerging as a new type of biometric authentication, using a person's unique chemical composition to confirm their identity. This article continues to discuss the new potential odorous option for the biometric security toolkit.
