Adelaide, Brisbane, Cairns, Darwin, Gold Coast, Melbourne, Perth and Sydney. So far only passengers exiting via international flights are affected. Domestic and international passengers departing Newcastle Port Stephens airport have been subject to body scanning since October 2019. Passengers who refuse a scan may be banned from flying. The scanners proposed to be used in Australia have shown a high rate of error in testing. Public outrage over the nude images created by the body scanners being collected by policy resulted in a lawsuit in 2010 to stop body scanning. Canada In Canada, 24 airports currently have these scanners in use, using millimeter-wave technology. Transport Canada notes that "Passengers selected for a secondary search can choose between the full body scanner or a physical search." United States In the U.S. full-body scanners have been installed at train stations, subways, penitentiaries and airports. After having previously used X-ray-based scanners the TSA currently uses Millimeter Wave AIT scanners exclusively, which show no identifying characteristics of the person being scanned. Instead, a generic outline of a person is used. As of December 2015, "While passengers may generally decline AIT screening in favor of physical screening, TSA may direct mandatory AIT screening for some passengers as warranted by security considerations in order to safeguard transportation security." Regarding privacy concerns the Transportation Security Administration (TSA) has stated in 2010 they "[have] not, will not and the machines cannot store images of passengers at airports". However the TSA later disclosed, in a response to the house chair on homeland security, that its procurement of airport scanners requires manufacturers to include image storage and transmission features but that these features should be disabled before being placed in an airport. The TSA shows 45 individuals have the ability to turn these machines into 'test mode' which enables recording images, but states that they would never do this on a production system. The US Marshal Service did operate a backscatter machine in a courthouse which records images. However, in a statement they noted that only individuals involved in a test were recorded. A sample of these images was received and disseminated by Gizmodo in 2010, using a Freedom Of Information Request. It is not clear if the US Marshal service has put these new scanning machines, that have recording capabilities, into production.
