touchless4f: A dedicated device for contactless fingerprint scanning

Developed over the last two decades, contact-based fingerprint authentication has found its place in various scenarios such as police control, border control, access control and forensics. To gain high biometric recognition accuracy, fingerprint samples have to be of high quality. To find its way into a broader field of application scenarios, fingerprint acquisition lacks in terms of hygienic harmless capturing and acquisition speed. Improving speed and decreasing hygienic concerns would also benefit for a higher convenience and public acceptance rate.

We present a special hardware-based approach for a dedicated device for contactless fingerprint scanning which is fast, small, cheap in price terms, and it delivers images of high quality.

The presentation will address the acquisition process, hardware setup, used elements, challenges in algorithmic design, quality estimation, shortcomings and potential improvements. At the end of the presentation there will be the chance to have some hand-on experiments on a device.
