Anlan writes "A Swedish student wrote her Master's thesis about current fingerprint technology. After a thorough literature study some live testing took place. Simple DIY fingerprint copies were used (detailed how-to in the thesis). Have current commercial products improved as much as proponents claim? Well, this qoute from the abstract says it all: 'The experiments focus on making artificial fingerprints in gelatin from a latent fingerprint. Nine different systems were tested at the CeBIT trade fair in Germany and all were deceived. Three other different systems were put up against more extensive tests with three different subjects. All systems were circumvented with all subjects' artificial fingerprints, but with varying results.' You can guess how happy the sales people at CeBIT were - most systems claim to be spoof proof..."
