Engelsma","Kai Cao","Anil K. Jain"],"abstract":"We open source an easy to assemble, spoof resistant, high resolution, optical\nfingerprint reader, called RaspiReader, using ubiquitous components. By using\nour open source STL files and software, RaspiReader can be built in under one\nhour for only US $175. As such, RaspiReader provides the fingerprint research\ncommunity a seamless and simple method for quickly prototyping new ideas\ninvolving fingerprint reader hardware. In particular, we posit that this open\nsource fingerprint reader will facilitate the exploration of novel fingerprint\nspoof detection techniques involving both hardware and software. We demonstrate\none such spoof detection technique by specially customizing RaspiReader with\ntwo cameras for fingerprint image acquisition. One camera provides high\ncontrast, frustrated total internal reflection (FTIR) fingerprint images, and\nthe other outputs direct images of the finger in contact with the platen. Using\nboth of these image streams, we extract complementary information which, when\nfused together and used for spoof detection, results in marked performance\nimprovement over previous methods relying only on grayscale FTIR images\nprovided by COTS optical readers. Finally, fingerprint matching experiments\nbetween images acquired from the FTIR output of RaspiReader and images acquired\nfrom a COTS reader verify the interoperability of the RaspiReader with existing\nCOTS optical readers.","url_abs":"http://arxiv.org/abs/1712.09392v1","url_pdf":"http://arxiv.org/pdf/1712.09392v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"raspireader-open-source-fingerprint-reader","repo_url":"https://github.com/engelsjo/RaspiReader","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
