A computer Security challenge: Finding humans. Build a test that AI
can’t pass.
Why
CAPTCHAs have gotten so difficult
… Because CAPTCHA is such
an elegant tool for training AI, any given test could only ever be
temporary, something its inventors acknowledged at the outset. With
all those researchers, scammers, and ordinary humans solving billions
of puzzles just at the threshold of what AI can do, at some point the
machines were going to pass us by. In 2014,
Google pitted one of its machine learning algorithms against humans
in solving the most distorted text CAPTCHAs: the computer got the
test right 99.8 percent of the time, while the humans got
a mere 33 percent.
Look for legal voids, make huge profits?
How your
health information is sold and turned into ‘risk scores’
… Over the past year, powerful companies such
as LexisNexis have begun hoovering up the data from insurance claims,
digital health records, housing records, and even information about a
patient’s friends, family and roommates, without telling the
patient they are accessing the information, and creating risk scores
for health care providers and insurers. Health insurance giant Cigna
and UnitedHealth's Optum are also using risk scores.
There’s no guarantee of the accuracy of the
algorithms and “really no protection” against their use, said
Sharona Hoffman, a professor of bioethics at Case Western Reserve
University. Overestimating risk might lead health systems to focus
their energy on the wrong patients; a low risk score might cause a
patient to fall through the cracks.
No law
prohibits collecting such data or using it in the exam room.
Congress hasn’t taken up the issue of intrusive big data
collection in health care. It’s an area where technology is moving
too fast for government and society to keep up.
