7 FingerTIP SDK Software and Biometric Algorithms
This chapter is intended to give users a brief overview (see figure 19) of the biometric
algorithms delivered optionally with the FingerTIP. These algorithms are part of the
FingerTIP SDK software package. Though the flow chart is simplified, it shows the
principles of the underlying signal processing performed on a processor engine. The major
software blocks of the biometric algorithms are the Encoder and the Matcher module.

Figure 19: Principle Software Data Flow
7.1 Enrollment
Enrollment is the process of generating the reference data set of a fingerprint. This data
set is used as the reference pattern which has to be matched for identification or
verification.
7.2 Verification
Verification refers to the process of comparing a fingerprint which has just been transferred
from the FingerTIP to the background processing engine with a set of reference data. As
a prerequisite the claimed user’s identity must be known to the system. The system
verifies this identity by comparing the current fingerprint with the fingerprint of the
reference image.
For detailed information on the software structure and its functionality refer to the Infineon
documentation: FingerTIP Software Package User’s Guide /4/ and FingerTIP
Software Package Programmer’s Guide /5/.
At the moment there is no exclusive international application programming interface
standard (API) for biometric applications. Actually several standards are being developed
right now, and the unification process is underway. Thus the FingerTIP
TM algorithms come
as the easy to use SDK, that has been created – where reasonable - in most compliance
with the respective versions of BAPI and HA-API standards. Infineon is a BioAPI member
and, once finished, the FingerTIP
TM SDK will be compliant with the BioAPI standard.
