Study shows we leave a trail of DNA behind us - even on the beach
Prof Yves Moreau, from Leuven University in Belgium, who analyses genetic data, said he did not think that the new study, which he was not involved with, raised any “immediate concerns” in terms of authorities being able to track people.
It was already known, Prof Moreau said, that people leave DNA in many locations, even on door handles, but the analysis of such “touch DNA” or “trace DNA” faces serious technical challenges, although they may be overcome by technology.
“Currently the landscape around DNA collection is very unclear,” he said. “The American Civil Liberties Union has argued because we cannot control where our DNA goes. We need to have that privacy respected as if it’s on your person.
“We need to have … a really good framework everywhere in the world that limits where and how our DNA is collected.”
