New: we proved it could be done. I used an AI replica of my voice to break into my bank account. The AI tricked the bank into thinking it was talking to me. Could access my balances, transactions, etc. Shatters the idea that voice biometrics are foolproof vice.com/en/article/dy7axa/h…

Models such as Stable Diffusion are trained on copyrighted, trademarked, private, and sensitive images. Yet, our new paper shows that diffusion models memorize images from their training data and emit them at generation time. Paper: arxiv.org/abs/2301.13188 👇[1/9]

"Given access to a synthetic dataset, a strategic adversary can infer, with high confidence, the presence of a target record in the original data." Synthetic data have a lot of value, so this study is concerning and disappointing to see. Though perhaps not surprising.

I got into a discussion with @OrinKerr the other day about the recent NYT op-ed on Signal and whether “metadata-resistant communications” is good or bad for policing and if it should be opposed. And I guess I wanted to talk about how those arguments should be approached. 1/

As experts have long been pointing out: NFTs are a lie. The "thing" you think you are buying is just a URL. When the website goes down, your NFT points to nothing.

I can’t tell what’s going on internally, but it looks like Apple has gotten over these concerns sufficiently to (soon) enable full encryption for iCloud backups. This will require users to opt in, and it will include a “social backup” feature in case you lose your passcode. 6/
