This report is an extension of the NIST Studies of one-to-one Fingerprint Matching with Vendor SDK Matchers which evaluated the accuracy of SDK (Software Development Kit) based on COTS (Commercial Off-The-Shelf) fingerprint matching systems for one-to-one verification applications. Fingerprint matching systems from twelve vendors were evaluated. The two finger matching evaluation is an extension of that testing used to evaluate the accuracy that can be achieved by combining the index finger scores to achieve a match. These results are based on the SDK matchers provided for the original single finger SDK testing. More details will be available from the Minutiae Exchange Test 2004 (MINEX04) The more accurate matchers in the two finger SDK scoring were able to achieve true accept rates (TAR) in the range of .985 - .998 at a false accept rate (FAR) of 0.0001.
