Interesting question, could be fairly easy to provide proof in the form of a photo of you inside the open doorway.
replyHow do you verify that a doorway in a photo belongs to a given address?
replyYou could have the person doing the knocking compare it when they arrive at the location.
replyThe more practical solution (excluding just using a normal alarm) would probably just sending a OTP to the address that needs to be entered before the first order.
Alternatively (not sure if this is available in the US, just basing this on the German ID cards), you could use the person's eID to verify their address. This is probably a bit too complex for a fun project like this one though.
Could be easy to spoof with AI image gen and a telephoto of the front door of Shooty McTriggerhappy, the neighbourhood crank whom Badfaith Faux-Customer would like to see knocked up.
