oh! er, Play Doh! “Fingerprint scanning devices often use basic technology, such as an optical camera that take pictures of fingerprints which are then “read” by a computer. In order to assess how vulnerable the scanners are to spoofing, Schuckers and her research team made casts from live fingers using dental materials and used Play-Doh to create molds. They also assembled a collection of cadaver fingers. In the laboratory, the researchers then systematically tested more than 60 of the faked samples. The results were a 90 percent false verification rate.” Link
