I think that part is made easier by the fact that I uploaded the ID in the first place under fully trusted conditions.

If I have the same physical piece of ID—as I imagine OP might have, upon release from prison—then they can directly compare it to the copy that I supplied previously. Scuff marks and specific document numbers included. I think that probably even scales.

If I lose access to my main identity document, one advantage of government ID is that I’ll urgently have it reissued. In most of the places I’ve lived, that’s the kind of thing you can validate against either the underlying authority or a sleazy-but-reasonably-accurate data broker. But in either case it’s out-of-band from my relationship with the tech company, in a way they can validate by semi- or fully-automated means, and with reference to an independent authority.

If somebody wants to physically mug me to steal my ID for access to my GitHub, I figure I’m pretty much out of luck—to paraphrase James Mickens [0], Mossad’s gonna Mossad.
