Chemical Traces in Your Phone Reveal Their Way of Life, Scientists Say

5616Molecular ‘Signature’ shows everything from cleaning products used for drug taken could help the police and medical professionals to build profiles of people.
As concerns about the personal data stored on your phone to keep you awake at night, you can outside of your phone a scrub.
Scientists say they distract the lifestyle of a person, to the type of cleaning products they use, the food they eat and the medicines they take, the chemicals found on the surface of your cell phone.
Experts say that the analysis of someone’s phone could be a boon for both health professionals and the police.
“Be the man versus reducing wife, if you find that using sunscreen, choose people who tend to be outside – so all these little clues can sort of narrowing the search space of a researcher candidates” said Pieter Dorrestein, co-author of the study from the University of California, San Diego.
Researchers from the United States and Germany, describe how the mobile phone were cleaned and the right hand of 39 persons and the samples were analyzed using the technique of highly sensitive mass spectrometry.
The results showed that every person a “signature” different set of chemicals in their hands that distinguish from one another. Moreover, these substances are overlapping in part with those of the phone, allowing devices to be distinguished from one another, and linked to their owners.
“If you look at the hands of an individual are unique in 99% of the samples examined. In two cases, it was not perfect, but in one of those cases people lived together,” Dorrestein said. “In 69% of cases, we were able to perfect the chemical profile, the molecular profile, the phone with the person to whom it belonged.”
But, he adds, the promise of the technology does not identify individuals, but to build a profile of the phone owner.
The analysis of the chemical fingerprint with the aid of a database of reference allowed the team to combine chemicals with family members to reveal well-known materials or telltale signs of the life of each individual, because, if they make use of treatments hair loss up as they antidepressants .
Some chemicals, such as DEET repellent, were found more than four months after the product was last used by the phone owner.
The approach, according to the authors, can be extended to a large database that can be used by the police to the lifestyle of a system on the basis of the specific set of chemical traces found on your telephone individual keys or to predict produce other objects.
They also suggest that the instrument can be used for various other purposes, such as monitoring human exposure to pollutants or controls or patients their medication or respond to certain drugs.
Melanie Bailey, an expert in forensic science at the University of Surrey, believes that the approach may prove valuable. “The problem is that if you have a cell phone, the fingerprints of developing it, but these numbers are completely useless if the donor is not a database or fingerprint dirty,” he said. “The information we have here could lead to annotate a list of suspects, or at least to provide some intelligence on what kind of person you should approach.”
But John Bond, former head of forensic services in Northamptonshire Police and associate professor of criminology at the University of Leicester professor, was less optimistic, noting that it is possible to detect traces of firearms, explosives and illegal drugs objects. It was less clear whether the chemical substances associated with lifestyle to identify criminals. “The problem is that they are not discriminatory things.
