Automated fingerprint recognition has matured as a reliable approach for authenticating humans through decades of research and development. Recent advances in fingerprint recognition are rapidly incorporating contactless finger acquisition. The rationale behind the progressive use of contactless fingerprint acquisition can be attributed to the improved user convenience, hygiene and prevention from the residual impressions. Emerging contactless fingerprint technologies enable deformation free and hygienic acquisition of ground truth finger ridge-valley details but pose new challenges for accurately matching with respective contact-based fingerprint images, billions of which are available in various government databases. In this talk, I will discuss on recent advances in contactless fingerprint identification technologies and share some of our results. We will also discuss on the technical challenges that are limiting the deployment of emerging contactless 3D fingerprint technologies and further research on the contactless fingerprint technologies.
