There are two sides to the technology. As someone who has been involved in digital image processing I find the algorithmic aspects interesting. But that is as far as it goes.

From a deployment side one perhaps two positives. No private rooms for the TSO perps they will now be out in the open. Second perhaps it will now only take two instead of three TSOs to conduct the scoping.

So while the above addresses the privacy issues, it does not address the primary issue efficacy. As such, TSA can invest all they want in processing software and even address the exposure issues. Until they address the efficacy it is more money down a piss hole.
