Fingerprint authenticating system |
摘要 |
<p>A fingerprint sensor acquires fingerprint information of an object being in contact. A light source irradiates a light to the object from a lateral side of the fingerprint sensor. A measuring unit measures a diffusion pattern of the light passing through the object. A determining unit determines whether the object is a live finger or an artificial finger based on the diffusion pattern measured by the measuring unit.</p> |
