How companies harvest your web search info
In the summer of 2015, Alexandra Franco got a letter in the mail from
a company she had never heard of called AcurianHealth. The letter,
addressed to Franco personally, invited her to participate in a study of
people with psoriasis, a condition that causes dry, itchy patches on
the skin.
Franco did not have psoriasis. But the year before,
she remembered, she had searched for information about it online, when a
friend was dealing with the condition. And a few months prior to
getting the letter, she had also turned to the internet with a question
about a skin fungus. It was the sort of browsing anyone might do, on the
assumption it was private and anonymous.
Now there was a letter,
with her name and home address on it, targeting her as a potential
skin-disease patient. Acurian is in the business of recruiting people to
take part in clinical trials for drug companies. How had it identified
her? She had done nothing that would publicly associate her with having a
skin condition.
