Fingerprint recognition is widely used in the modern digital society and has become synonymous with reliable method of personal identification. However, artificial finger gummies with embedded fingerprints may easily spoof the current fingerprint system, which relies on the surface scanning of a finger. In this paper Optical Coherence Tomography (OCT) is applied to distinguish the artificial material, such as liquid silicone rubber and glue, as well as the real finger. Though the commercial fingerprint reader was easily spoofed by these artificial fingerprints, the OCT system easily detected them at all times.
