Sorry I was unclear and linked to the wrong article, I meant that wapo journo poking around led to DHS & CBP responding on the record. It was one in the line of recent articles about facial recognition that travelers can opt-out of but nobody is sure how exactly you are supposed to do so. The wapo article I linked did attribute The Register info linking Perceptics. Both wapo articles are linked in this tweet: https://twitter.com/geoffreyfowler/status/113817627922244403...
> And on Monday, after I published this column online, Department of Homeland Security officials called me to disclose that photos of travelers were recently taken in a data breach, accessed through the network of one of its subcontractors.
