What would hacks of augmented reality look like? Imagine a see-through AR display on your car helping you navigate—now imagine a hacker adding images of virtual dogs or pedestrians in the street.

Franzi Roesner, 31, recognized this challenge early on and is leading the thinking into what security and privacy provisions AR devices will need to protect them, and ourselves. Her research group at the University of Washington created a prototype AR platform that can, for example, block a windshield app from hiding any signs or people in the real world while a car is in motion.

 “I’ve been asking the question, ‘What could a buggy or malicious application do?’” she says.
