Creating templates for fingerprint authentication

摘要

The present invention concerns a method, a system, a device for enrolling biometric data of a body part to be used for user authentication, using a two-dimensional sensor. The method comprises capturing, using the two-dimensional sensor, images representing different views of the body part, stitching the images into at least one mosaic, generating at least one constructed image by determining at least one area of interest in the mosaic, the area of interest representing an additional view of the body part, and extracting image data of the area of interest, and enrolling the constructed images in a set of templates to be used for user authentication.

1. A method in a biometric sensing system, of enrolling biometric data of a body part, to be used for user authentication, using a two-dimensional biometric sensor, the method comprising:
capturing, using the two-dimensional biometric sensor, images representing various views of the body part, wherein each of the images corresponds to a single and separate touch of the body part on the two-dimensional biometric sensor, stitching the captured images into at least one mosaic, generating at least one constructed image by determining at least one area of interest in the mosaic, the at least one area of interest representing an additional view of the body part that is different than the various views of the body part represented by the images, and extracting image data of the at least one area of interest, and enrolling the at least one constructed image in a set of templates to be used for user authentication.
