Biological recogntion of human faces

3D touchless fingerprinting
Dr. Giuseppe Parziale
TBS Holding AG

The current fingerprinting technologies rely upon either applying ink (or other substances) to the finger tip skin and then pressing or rolling the finger onto a paper surface or touching or rolling the finger onto a glass (silicon, polymer, proprietary) surface (platen) of a special device. In both cases, the finger is placed on a hard or semi-hard surface, introducing distortions and inconsistencies on the images.

Touchless technology is a novel approach to acquire fingerprints. Introduced the first time by TBS, touchless fingerprinting combined with the 3D representation of the finger can achieve superior results than traditional enrollment methods in terms of image quality and fingerprint matching.

The lecture on 3D touchless fingerprinting will provide:

1. an overview of the new involved image-processing and 3D matching algorithms introduced by TBS for this innovative capture approach;
2. a new liveness and fake detection approach;
3. a demonstration of the Surround Imager™, a live-scan device able to capture a rolled-equivalent fingerprint without the need of touching any surface; and
4. an overview of the current development of the Touchless Sweep Sensor™, a new fast-capture device able to acquire all the fingerprints and the palmprints of both hands.
