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.
