Abstract: Some disclosed methods involve performing a fingerprint enrollment process involving obtaining fingerprint image data via a first fingerprint sensor of a fingerprint sensor system including two or more fingerprint sensors and creating a first fingerprint sensor template for subsequent fingerprint authentication via the first fingerprint sensor. Some disclosed methods involve determining a second fingerprint sensor of the fingerprint sensor system for which a fingerprint template will be created, determining one or more second fingerprint sensor characteristics of the second fingerprint sensor and creating a second fingerprint sensor template for subsequent fingerprint authentication via the second fingerprint sensor based, at least in part, on the first fingerprint sensor template and the one or more second fingerprint sensor characteristics. In some examples, the method may involve creating the second fingerprint sensor template without performing an enrollment process involving the second fingerprint sensor.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may receive, from a fingerprint scanner, fingerprint scan data associated with an image that depicts a scanned fingerprint of a user; process, using a model-based iterative reconstruction (MBIR) model, the fingerprint scan data to generate an enhanced image associated with the image; and perform, based at least in part on the enhanced image, a match analysis to authenticate the user. Numerous other aspects are provided.
