    Anti-adversarial machine learning defenses start to take root

    pubsub.slavino.sk / infoworldcom · Thursday, 19 November - 11:00 edit

Much of the anti-adversarial research has been on the potential for minute, largely undetectable alterations to images (researchers generally refer to these as “noise perturbations”) that cause AI’s machine learning (ML) algorithms to misidentify or misclassify the images. Adversarial tampering can be extremely subtle and hard to detect, even all the way down to pixel-level subliminals. If an attacker can introduce nearly invisible alterations to image, video, speech, or other data for the purpose of fooling AI-powered classification tools, it will be difficult to trust this otherwise sophisticated technology to do its job effectively.

Growing threat to deployed AI apps

This is no idle threat. Eliciting false algorithmic inferences can cause an AI-based app to make incorrect decisions, such as when a self-driving vehicle misreads a traffic sign and then turns the wrong way or, in a worst-case scenario, crashes into a building, vehicle, or pedestrian. Though the research literature focuses on simulated adversarial ML attacks that were conducted in controlled laboratory environments, general knowledge that these attack vectors are available will almost certainly cause terrorists, criminals, or mischievous parties to exploit them.
