Image recognition technology may be sophisticated, but it is also easily duped. Researchers have fooled algorithms into confusing two skiers for a dog, a baseball for espresso, and a turtle for a rifle. But a new method of deceiving the machines is simple and far-reaching, involving just a humble sticker.

Google researchers developed a psychedelic sticker that, when placed in an unrelated image, tricks deep learning systems into classifying the image as a toaster. According to a recently submitted research paper about the attack, this adversarial patch is "scene-independent," meaning someone could deploy it "without prior knowledge of the lighting conditions, camera angle, type of classifier being attacked, or even the other items within the scene." It's also easily accessible, given it can be shared and printed from the internet.

    Where I work we have a security demo station that I have done some testing with. It may depend on the quality of the cameras, and whether they are designed to supplement visible spectrum with IR for night vision as some of them are equipped with, but even my "up to 1W" blue beam was unable to permanently damage any of the cameras I attacked (with authorization of management). This suggests that the output, even in wide "unfocused" spread would have to be significant enough that injury to the user is a real possibility. As I said, you don't see the IR, so unlike having a bright flashlight clipped to the front of your shirt where you can tell that you need to aim it away or squint a little bit sometimes and be fine, the safety margin is too thin for my comfort.

    Try taking an average TV remote. Most of them are NIR, and can demonstrate washout pretty well (or lack thereof, as the case may be). I found them to be mildly annoying at best and not significantly impairing recognition in the video stream, but again, haven't worked up into stronger LEDs for the above reasons. Not to mention, your power source would need to be bulkier and/or more often refreshed when your power output is boosted.
