U.are.U SDK - Developer Guide 20
Upgrading from previous SDKs
Changes in U.are.U Terminology from Previous Usage (Gold and One Touch)
This section describes differences in terminology between this product and the One Touch and Gold documentation.
Upgrading from U.are.U UPOS for OPOS/JavaPOS
This new U.are.U SDK version of the OPOS and JavaPOS APIs are backward-compatible. However the following new
features may or may not affect your existing applications:
• The default data format has a longer header. The default data format is now fully compliant with UnifiedPOS
1.13. The default data format is the same as the old format except that the template header has additional bytes of
information, i.e., a 45-byte header, instead of the previous 10-byte header for JavaPOS and 12-byte header for
Old Term New Term Explanation
Fingerprint authentication Fingerprint verification Change in industry standard terminology.
Fingerprint registration Fingerprint enrollment Change in industry standard terminology.
Fingerprint sensor
(referring to a fingerprint
capture device)
Fingerprint reader Erroneous usage: Sensors are a component of certain
types of fingerprint capture devices, they are not
themselves fingerprint capture devices.

Fingerprint template
Fingerprint minutiae data
Fingerprint templates (fingerprint features stored for
enrolled fingers) and fingerprint feature sets (images
used for verification and identification) have been
replaced with fingerprint minutiae data in the U.are.U
family of the SDKs only. With standards-based data
formats in the U.are.U SDKs, all fingerprints are stored
in the same format.

ROC curve DET curve More accurate terminology. We have never used ROC
curves, however our DET curves were sometimes
erroneously called ROC curves in the past.
FAR FMR or FNMR as
appropriate
The definition of FAR is application-specific.
In some applications FAR is similar to FMR while in
other applications, FAR is similar to FNMR.
FRR FMR or FNMR as
appropriate
The definition of FRR is application-specific.
In some applications FRR is similar to FNMR, while in
the others FRR is similar to FMR.
