Chemical Traces On Your Phone Reveal Your Lifestyle, Scientists Say (theguardian.com)
An anonymous reader quotes a report from The Guardian: Scientists say they can deduce the lifestyle of an individual, down to the kind of grooming products they use, food they eat and medications they take, from chemicals found on the surface of their mobile phone. Experts say analysis of someone's phone could be a boon both to healthcare professionals, and the police. "You can narrow down male versus female; if you then figure out they use sunscreen then you pick out the [people] that tend to be outdoorsy -- so all these little clues can sort of narrow down the search space of candidate people for an investigator," said Pieter Dorrestein, co-author of the research from the University of California, San Diego. Writing in the Proceedings of the National Academy of Sciences, researchers from the U.S. and Germany describe how they swabbed the mobile phone and right hand of 39 individuals and analyzed the samples using the highly sensitive technique of mass spectrometry. The results revealed that each person had a distinct "signature" set of chemicals on their hands which distinguished them from each other. What's more, these chemicals partially overlapped with those on their phones, allowing the devices to be distinguished from each other, and matched to their owners. Analysis of the chemical traces using a reference database allowed the team to match the chemicals to known substances or their relatives to reveal tell-tale clues from each individual's life -- from whether they use hair-loss treatments to whether they are taking antidepressants.
if you could make the phone detect those things itself, what an amazingly invasive thing that! they are talking about doing it in a lab here but imagine the bio sensors really taking off
Can't you just get all that information from the persons phone and social profile?!
Just say it, the semen all over my phone makes it obvious I'm a Slashdotter.
This technique will soon be used by law enforcement to profile persons with encrypted phones, especially at the borders. I will be sure to stick mine up my ass before handing it to them.
This is in no way a surprise to learn that the chemicals on the hand that picks up and handles the phone are also on the phone. I wonder who paid for this study and what agencies the scientists are hoping will continue to fund further research that further proves that when you touch something you transfer what you had on the surface of your hands. Are they hoping that law enforcement supports their work? This might be useful where burner phones were used in a crime and were wiped to remove prints. Outside of that scenario, I don't see another practical use for this analytical method..

...with a Samsung Galaxy Notes 7! This smartphone has been carefully designed with privacy in mind: it incorporates a very low level phone formatting mode to erase completely not only data, but also chemical substances that could compromise user's privacy.
All these latest articles seem like preparing us for the inevitable.
"Oh so you like privacy, burner phones and shit?, look what we have come up with, cool right? right."
This certainly making the creepiness great again.
the people that snort coke from their phone's screen...
Hey everyone, I have a new startup and I'm looking to get funded. We're going to provide smartphone recovery services based on chemical signature. Just register your unique chemical signature, and if your phone ever gets lost, we'll find it for you. All your information will be protected with military-grade encryption. Join us and help change the world by making it a better place!
* First round of funding has already been started by In-Q-Tel.

This reminds me of a story I read where Stalin had a special toilet installed for a diplomatic visit from Mao. The toilet didn't drain into the sewer, but into a special tank. Then the Soviets did nothing with Mao but feed him as much food as he could possibly eat for ten days. At some point he angrily shouted that he was in Russia to do more than just eat and shit. Meanwhile Stalin had a crack team of scientists secretly collect and analyse Mao's stool samples for clues into his personality. They took it so seriously that they decided not to sign a trade agreement or something. Source.

They're going to find fecal matter, aren't they?
In other words they are saying you probably shouldn't lick someone else's cellphone (or your own for that matter)? What are we supposed to do when the screen gets all sticky and cheeto covered?
..so they are going to have to do their forensics the old fashion way with me.
BTW remind me that I should write a book about not owning a mobile telephone in the 21st century.
I think I will call it "The narcisists and me."
Till a 'study' with a sample size of 39 is used by a prosecuting attorney as 'fact' and the plebe of a public defender rolls under it and does not contest. Juries love forensic 'experts' makes things look a bit more like the CSI drivel they watch.
Silence is a state of mime.
It's what smartphones are for, yes?
And jizz.
"they swabbed the mobile phone and right hand..."
So, do the tadpoles interfere with the imagery?

The chemical traces *anywhere* in my house or on my person (take that how you desire) will reveal even more about my lifestyle! I would probably just answer any question asked anyway.
OMG facts!
If you have access to someone's phone, and a legitimate reason to ask, the phone company can easily give you their identity based on the phone's MEID and SIM card information. If it's a burner phone, you can still get more information about how/where it was purchased in a much shorter time than any of this information will provide about the person.

I was intrigued (I suppose that I still am) until the comment about sunscreen and being outdoorsy. Herein lies the danger of such things, but I assume it is poor journalism rather than poor science (or, at least, I hope the scientists aren't concluding this).
You see, I wear sunscreen. Religiously. I am not terribly "outdoorsy". I am paranoid about skin cancer (runs in the family) and wrinkles (I'm a bit vain, what can I say).
I think what they meant to say is, given a population with certain characteristics, one can infer certain probabilities about the population. While this is interesting in a population, it's also the same horse s#!t that results in me getting Facebook ads centered around marijuana because I align closely with libertarians (but I don't smoke pot. At all). I long for the day when our marketing overlords start sending me phone ads for paddle boarding or tennis or outdoor yoga because I wear sunscreen. It's so much easier to tune out stuff that has zero relevance.
Just replace the word "PHONE" with any of the words below:
1. Lipstick
2. Chopsticks
3. Keyboard
4. Comb
5. Underwear
6. anything you touch.......................
But I work in chemistry and microbiology. Might be neat to see what they derive from that.
Sounds like something that can be done with any personal item someone keeps on themselves all of the time including pocketbooks, baseball caps, glasses, jackets, etc....
Really, no thanks. May you all fall into the sea along with all your research.
Condoms for cell phones! The new iDOM...protection for using your phone. The new GalaxyDOM....explosive results!
I'm sure in a lot of cases you could also learn a lot from using a black light to examine the phone... :-)

All they're gonna get from mine is pizza and mac n' cheese.
Once sniff of your ass and your dog knows more about what you've been up to than your spouse, your boss, and the NSA combined.
They're gonna find out I like to eat oatmeal and use Crest toothpaste. Good thing I use a mini tablet when nature is calling. Otherwise they would find out I can only beat FreeCell half the time.
If your phone has micro bits of cocaine or heroin on it is it enough to get a conviction? After all, it is possession. And if your child goes to school and micro amounts of dope can be found on their skin or clothing should the home be raided? This technology just might create some serious social discomfort. What's a criminal to do ?
What if you use a phone case ?
How easily can it be defeated? Would it be possible to collect samples in public places and add them to your phone's chemical signature to throw people off your scent?
