Abstract
A fake finger discrimination device includes a fingerprint sensor and a control processor. The fingerprint sensor senses a rotating finger to obtain fingerprints in a fake finger discrimination mode. The control processor electrically connected to the fingerprint sensor, judges whether the fingerprints match with one another by way of rotation correlation comparison. If the fingerprints match with one another, the finger is determined as true. If the fingerprints do not match with one another, the finger is determined as fake. A fake finger discrimination method is also disclosed.
