Fingerprint Recognition Software Development
Kit (Platinum
Edition)
Digital
Persona’s Platinum Fingerprint Recognition
Software Development Kit
(SDK) enables developers to add the power
of fingerprint authentication security to
their networked applications. This powerful,
multi-layered toolkit provides a set of DCOM
objects that enable developers to access all
the functionalities of the system in a very
flexible way. The toolkit includes the Device,
the Engine, the High Level Functions and the
User Database. The toolkit’s Security Layer
is completely transparent to the application
developer. The Toolkit uses PKI based on X.509
certificates both to set up trust relationships
among client to server in the domain and to
ensure data integrity.
Device
The
device component
provides both
physical device
and Plug-and-Play
(PnP) management
functions. It
supports security
features such
as the use of
a challenge- response
protocol to avoid
playback attack
when communicating
with a remote
server. Secure
images produced
by the sensor
are only decrypted
on a secure server.
Engine
The
engine component
provides the basic
functionality
of feature extraction,
matching, and
registration of
the fingerprint.
Feature
Extraction
The
feature extraction component removes defining
characteristics of biometric samples and
organizes them into a template. The Digital
Persona Fingerprint Feature Extraction component
implements a minutiae-based algorithm that
accepts grayscale images with a minimum
of 250dpi and 16 gray levels. Extracted
templates are completely hardware independent.
Compressed templates are signed and encrypted
prior to export.
User
Database
The
user database
contains user
information including
fingerprint templates.
User Records are
system objects
that can be securely
exported. An implementation
of a persistent
storage is also
provided.
Matching
The
matching component compares a registered
template to the one provided by the user
to ensure authentication. The algorithm
is rotation invariant. Digital Persona quotes
a False Accept Rate of 0.01% for a False
Reject Rate of 1.4%. The Digital Persona
Fingerprint Matching component generates
a registration template from a set of fingerprints,
adapting to the quality of the fingerprint
that is being imaged. This process consists
of extracting features from each print and
combining them into one robust template.
High
Level Functions
The
toolkit provides
a high level interface
to the Device
and to the Engine.
The various functions
(including Enroll,
Verify, and others)
require the services
of several components.
Individual components
can be instantiated
on different network
nodes for maximum
flexibility and
security. The
Interface is usable
from C++ and all
other scripting
languages including
Visual Basic.
The user interface
is designed as
a separate object
for extreme flexibility.
The User Interface
components are
all ActiveX components.
Developers that
do not want to
use the User Interface
that is provided
can develop and
use their own
instead.
