For completeness, and as a followup after all the 'deleted immediately' assertions, and to keep the 'nothing to hide' crowd happy (that their images *will* inevitably end up on the web):
Reg 12/1/10 : US airport body scanners can store and export images
Quote:
Full body scanners at US airports can transmit digital strip search images of people, contrary to US Transportation Security Authority assurances.
[...]
According to the TSA procurement specification, v1.02, 23 September 2008, the scanner, termed a Whole Body Imager (WBI) will have "a high capacity read/write drive... to permit data uploads and downloads." It will also "provide capabilities for data transfers via USB devices" and support both Ethernet and TCP/IP. Field reporting data for up to a year will be stored on the hard drive.
No indication that I can see of the capabilities of the ones to be used at UK airports but it's unlikely that the machine functional specs would be much different.
[ It's not normal practice to post followups once something has been moved into this section - but the apparent disparity between the announcement and the facts did seem to warrant it in this case. And no, this isn't a call for further additions... ]
