  • What device you use is one of the biggest data points advertisers and trackers use to fingerprint you across the internet. No, “I use a Google Pixel 9” does not, by itself, de-anonymize you, but it does make a big dent when combined with other information.

    You keep talking about “proving the authenticity of an image” with something that does not even move you .00000001% towards an image being legitimate. It is literally zero information about that question in every possible context. It is, eventually, if you throw out every camera on the planet and use heavy cryptography, theoretically possible to eventually, in the future, provide some evidence that some future picture came from some specific camera, but it will still not be proof that what that camera processed wasn’t manipulated.




  • No, you cannot use metadata as even extremely weak evidence that an image is real. It is less than trivial to fake, and the second anyone even hints at making it a standard approach, it will be on every photo anyone uses to mislead anyone.

    Most photos on the internet are camera phones, and you absolutely are not entitled to know what phone someone has. Knowing someone’s phone has infinitely more value to fingerprinting a user than including metadata could ever theoretically have to demonstrate whether a photo is legitimate or not.

    Photos without a specific, on record provenance from a credible source are no longer useful for evidence of anything. You cannot go back from that.









  • The point isn’t “it’s their fault”. But it changes the dynamic.

    An enthusiast community can, for good and bad, largely self regulate. It’s easier to keep corporate interests either out, or engaging on your terms.

    Once the community grows to include a high enough proportion of casual participants, that ability goes away, because manipulations that don’t work on inquisitive expert audiences do work on less informed ones, and less willing to question. It’s harder to establish who actually knows what they’re talking about by reputation, it’s harder to weed out the trolls from the naive, and it’s just generally harder to keep the focus of the community where you want it to be.

    Corporations are one of the groups of bad actors manipulating that difference in dynamics, but the dynamics are different because of the large influx of people who don’t understand as much and aren’t trying to.
