Humans have nasal respiratory fingerprints

Kind of a silly personal anecdote, but growing up, my father had a unique "strained" nostril breathing pattern and bad sleep apnea + COPD. I became 'hyper aware' of people's breathing patterns - to the point where people at work had fun with it - standing behind me breathing normally. I could identify who it was > 90% of the time (they were not trying to breathe quietly or differently). I often thought of people's breathing signature as sort of factor to identify them by. I certainly didn't think I was the first person to note this.

More interestingly, I'm also able to pick out people who have early signs of "decreased health" based on their breathing pattern at rest - I don't think it's overly difficult.

This study appears to cover both aspects - creating a breathing fingerprint and estimating BMI. I certainly wasn't aware of breathing differences associated with cognitive state. Bravo to the researchers for formalizing all of this - hope some positive interventional techniques are driven by these findings.

Can't wait for my phone to identify me by making an impulse response recording of my nose so I can convince it that I'm me at 6 in the morning.

For the past few years I have had difficulty working out in the yard, and then in 2018 it got harder and harder to breathe. After many tests, it was a CT scan that showed Emphysema, and scarring in my lungs. I quit smoking 8 years ago, but the damage has been done. I got to a point I couldn’t catch my breath and was coughing so hard I thought the top of my head would blow off; nothing was really working to help my condition. Finally, I started on the COPD formula, and with the help of this treatment, I’m active again. Its effects on emphysema are amazing; all my symptoms gradually faded away. I breathe much more freely now and no longer need my oxygen cylinder! Google uinehealthcentre. net to get this formula. I'm surprised a lot of people with COPD/emphysema haven't heard of the formula.

Today it requires wearing a mask to effectively capture the data. I wonder if we will see this done acoustically or via some other non-intrusive, remote method.

There should be nothing surprising about this. Any physiological characteristic of a human being, -subject as it is to thousands or millions of morphological variations caused by the fuzziness of biological creation- can quickly become a unique identifier. All you need is a method for quantifying it. We started with fingerprints in the 19th century, now we have man others, and especially DNA. Respiratory "fingerprints" aren't useful in the sense that they're left behind like DNA or fingerprints, but as a biometric marker, they make sense.

Not very practical when they have to record the sample for several hours with a mask. I'm sure in 10 years they'll be able to do it with a 10 second sample as you walk by, though.

I once went to see a doctor because of anxiety, and they had me try some simple breathing exercises. That was when I first noticed how much my breathing pattern changes depending on my state. Now whenever I feel tense, I consciously slow down my breathing and it actually helps me feel more in control. After reading this article, the idea of a breathing fingerprint makes a lot of sense to me. It probably reflects not just physical traits but also your current state.

It appears like you need a rather long sample (hours) to have a good chance of identifying someone.

Is a fingerprint only workable as an identifier in 94 out of 97 people? (I assume no because ex. Apple shipped touch ID)

Wasn't there an app for recording and analyzing coughs for the early detection of cancer or similar?

I guess I'll just have to Wim Hof Breathe all day so they can't catch me!

In the future, US citizens wanting to exercise their 4th amendment right against unlawful seziure of their biometrics will do so by ceasing to breathe.

Because you can't require a warrant for biometrics that you impart to the (public) environment around you, like fingerprints on a door handle, saliva on a discarded cigarette, or in this case... air.
