A type of body scanner in wide use across U.S. airports through last year fails to spot well-concealed weapons including guns and knives, computer security researchers contend.
The Rapiscan Secure 1000 full body scanner provides only “weak protection against adaptive adversaries,” according to their
paper, which will be presented on Thursday at the Usenix Security Symposium in San Diego. The researchers also set up a
website with their findings.
“It is possible to conceal knives, guns and explosives from detection by exploiting properties of the device’s backscatter X-ray technology,” the paper said.
Although the Rapiscan Secure 1000 was retired from U.S. airport use last year, it is still used at court houses and prisons. Airports currently use millimeter-wave scanning technology, which the researchers have not tested.
