I have often wonder how many passwords do security cameras capture when people type then on their phones or laptops, also stuff like one-time codes or credit card numbers and so on.
So, knowing 8490 worked for me is often entirely useless immediately, and if not it'll be useless within say 10 minutes.
You might think if you collect enough of them you'll be able to guess the next one. In principle that's true, but for all real systems you're fighting an actual cryptographic hash in there somewhere, so it's like you decided second pre-image attack on the hash (much harder than collision) wasn't difficult enough, you want hard mode.
I see photos being automatically OCRed by default now ... in Google Photos, in Microsoft SharePoint etc.
I am just imagining that in future a GPT Vision processing of all videos ever captured might become similarly prevalent (and cheap).
Which would open up a very easy attack vector / leakage of secrets ... like phone unlock pins and passwords.
I am in the same boat as the comment I replied to -- concerned about new risks that new tech might bring to the table.
My post was just "extrapolating" the risk to a larger scale -- not just one video clip being manually decoded, but all footage automatically spitting out secrets as simply as a Closed Caption / video transcript of today.
