Biometric Access Protection Devices and their Programs Put to the Test (c't)

C't has published a study of eleven biometric access controls intended to prevent unauthorized access. "In our attempts at outfoxing the protective programs and devices we have concentrated on the first method: direct attempts at deceiving the systems with the aid of obvious procedures (such as the reactivation of latent images) and obvious feature forgeries (photographs, videos, silicon fingerprints)."
