Bracing Medical AI Systems for Attacks

There’s new advice on how to handle tampering that fools algorithms and enables healthcare fraud Last June, a team at Harvard Medical School and MIT showed that it’s pretty darn easy to fool an artificial intelligence system analyzing medical images. Researchers modified a few pixels in eye images, skin photos and chest X-rays to trick deep learning systems into confidently classifying perfectly benign images as malignant. These so-called “adversarial attacks” implement small, carefully designed changes to data—in this case pixel changes imperceptible to human vision—to nudge an algorithm to make a mistake. That’s not great news at a time when medical AI systems are just reaching the clinic, with the first AI-based medical device approved in April and AI systems besting doctors at diagnosis across healthcare sectors. Now, in collaboration with a Harvard lawyer and ethicist, the same team is out with an article in the journal Science to offer suggestions Continue reading Bracing Medical AI Systems for Attacks
