Methods and systems for automated fingerprint recognition
First Claim
1. An image acquisition system, comprising:
- a dark field image acquisition device for producing a first output representative of a finger;
a bright field image acquisition device for producing a second output representative of the finger;
a processing entity configured to combine the first and second outputs to create a composite fingerprint image representative of the finger.

Abstract
A method of identifying a donor of a fingerprint image exhibiting a pattern of minutiae. The method comprises deriving a donor index code and a donor match code associated with the donor fingerprint image. A database of records is accessed—each record being associated with an identity and indicative of a respective index code and a respective match code—in an attempt to identify at least one record for which the respective index code corresponds to the donor index code. Responsive to the attempt being successful, it is determined whether any of these “candidate” records includes a particular record for which the respective match code corresponds to the donor match code. Upon indeed determining that this is so for a particular record, an output is generated, such output being indicative of a conclusion that the donor of the fingerprint image has the identity associated with the particular record.
