Contactless Fingerprint Capture and Data Interchange Best Practice Recommendation



Shahram Orandi, John M. Libert, Craig I. Watson, Gregory Fiumara, John Grantham


While contactless fingerprint capture devices stand to provide for many benefits, images from this nascent technology are sufficiently different than traditional contact-collected images thereby warranting the separation of these new contactless fingerprint images from legacy contact-collected images and systems operating on them. This Best Practices Recommendation defines voluntary (informative) changes to the ANSI/NIST standard to allow for the creation of contactless transactions that are not readily ingestible by existing systems, but based closely on ANSI/NIST so that minimal changes to the system can allow for processing. Furthermore, the transactions can include the original sensor data, in addition to the contact-compatible/interoperable image in the event that vendors improve their technologies and allow for the reprocessing of the data without recapturing.
