Fingerprints are one of the most important biometric characteristics due to their uniqueness and persistence. Touch-based schemes are widely implemented but show some issues e.g. the presence of latent fingerprints or hygienic concerns of the users. Touchless recognition schemes circumvent many of these issues and form a fast, user-friendly and hygienic way of fingerprint recognition. This work presents an automatic touchless fingerprint recognition scheme based on a state-of-the-art smartphone. We propose a run-through on all steps of the recognition pipeline and discuss important requirements for a fully automatic recognition scheme. During a database acquisition touchless samples are captured of 29 subjects in different environmental situations and with sensor types. Evaluations on the acquired database show a comparable performance of our touchless scheme to the touch based one under constrained environmental influences. Also, the interoperability test between both systems shows a good performance. A usability study show that the subjects prefers the touchless capturing method.
