New 'Nightshade' tool lets artists fight back against AI by poisoning their own art

Researchers developed a tool called Nightshade that can "poison" AI image generators by altering pixels in artists' work, causing unpredictable/faulty results.

Nightshade aims to fight back against unauthorized use of artists' work to train AI models without permission.

It works by subtly changing images so AI interprets them as something entirely different than what they actually depict.

Poisoning attacks could potentially disrupt/corrupt AI art generators, but could also be misused by bad actors.

Authors suggest Nightshade may encourage model trainers to get artist permission, but it also allows artists to sabotage AI using their work without consent.
