If you are trying to hide something from someone, you create more noise. So much noise around it that even though it's in plain sight, nobody can tell which is real and which is added. Easy examples in Cryptonomicon by Neil Stephenson and The Imitation Game movie. To hide something, you add a shit ton of false information. I imagine conspiracy theorists could be incredibly useful tools/unwitting dupes to various intelligence agencies for hiding the real stories.
AI makes effortless noise. The closer it gets to being indistinguishable from reality, the better the noise. Just like that story of people wearing a fake sixth finger to make camera footage look like AI. AI will make noise, and it will hide a hell of a lot in that noise. AI will definitely be a tool to invade privacy. But it will also be a tool to create privacy, and hide things. Double-edged sword, fun times.
