Scientists Create Breath Biometrics, Ability To Identify Someone With Their Breath

Published in Cornell University’s Arxiv studies database, titled “User authentication system based on human exhaled breath physics,” wrote in the summary description:

This work, in a pioneering approach, attempts to build a biometric system that works purely based on the fluid mechanics governing exhaled breath. We test the hypothesis that the structure of turbulence in exhaled human breath can be exploited to build biometric algorithms. This work relies on the idea that the extrathoracic airway is unique for every individual, making the exhaled breath a biomarker.

Methods including classical multi-dimensional hypothesis testing approach and machine learning models are employed in building user authentication algorithms, namely user confirmation and user identification. A user confirmation algorithm tries to verify whether a user is the person they claim to be. A user identification algorithm tries to identify a user’s identity with no prior information available. A dataset of exhaled breath time series samples from 94 human subjects was used to evaluate the performance of these algorithms.

The user confirmation algorithms performed exceedingly well for the given dataset with over 97% true confirmation rate. The machine learning based algorithm achieved a good true confirmation rate, reiterating our understanding of why machine learning based algorithms typically outperform classical hypothesis test based algorithms. The user identification algorithm performs reasonably well with the provided dataset with over 50% of the users identified as being within two possible suspects.

We show surprisingly unique turbulent signatures in the exhaled breath that have not been discovered before. In addition to discussions on a novel biometric system, we make arguments to utilise this idea as a tool to gain insights into the morphometric variation of extrathoracic airway across individuals. Such tools are expected to have future potential in the area of personalised medicines.

AUTHOR COMMENTARY

Something that I have repeatedly noted in so many of these new, innovative, wild technologies, is that they are almost always marketed as some great medical intervention that will ultimately benefit only a fairly small percentage, if that.

Of course, my cynicism and pessimism cannot help but raise caution towards this. After all, we know that elites want to and are arbitrarily measuring in carbon and emissions; and we know already that some of the lunatics have posited that breathing is bad for the environment. I can already imagine big-tech using something like this to track who is emitting how much, and by extension what they ate and drank. Again, we are carbon they want to reduce.

It is interesting that these scientists have determined that they can track and ID someone with their breath; as this is a confirmation that the statements made in the scriptures are true, that God gave man his own unique spirit and life in him.

And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.

The Spirit of God hath made me, and the breath of the Almighty hath given me life.

If he set his heart upon man, if he gather unto himself his spirit and his breath;

Genesis 2:7; Job 33:4; Job 34:14

[7] Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock? [8] Say I these things as a man? or saith not the law the same also? [9] For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen? [10] Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope. (1 Corinthians 9:7-10).
