You write, "It's slow, but it doesn't have to be warp speed to send over facial map data."
Excuse me, but do you hear yourself? Speed isn't an issue when you are trying to identify god knows how many people entering a polling place? That is tons of information required at a rate that you have no control over.
It doesn't matter though as the software just doesn't work under these haphazard circumstances.
The speed of a network link is not a factor in the processing algorithm, the CPU is, and I was talking about the speed of CDPD cellular modems. Presumably, each laptop is capturing the images and generating the face maps locally, and sending the resulting digested and compressed data up over the 9600-14,400bps CDPD link to the central location where it is stored in a database of all polling places and voters.
The facial comparasons against the rest of the database are presumably then done by the central computer, not by the laptop. If there's a hit, the laptop operator is presumably notified with the details.
There's a window of five minutes or so during which a person would be in the polling place, or longer if the line is long, during which the comparison can be done, a double-voter identified, and subsequently apprehended.
