Our key-less and password-less future will hinge on being identified via our fingerprints, irises, and vocal tones. The problem is, someone else may have a copy of your finger. Via the BBC:
A Brazilian doctor faces charges of fraud after being caught on camera using silicone fingers to sign in for work for absent colleagues, police say.
Thaune Nunes Ferreira, 29, was arrested on Sunday for using prosthetic fingers to fool the biometric employee attendance device used at the hospital where she works near Sao Paulo. She is accused of covering up the absence of six colleagues. Her lawyer says she was forced into the fraud as she faced losing her job.
Police said she had six silicone fingers with her at the time of her arrest, three of which have already been identified as bearing the fingerprints of co-workers.
