Griaule SDK Description

GrFinger is Griaule Biometrics’ fingerprint recognition software development kit(SDK). With fingerprint recognition becoming the norm across a wide variety of platforms, Griaule’s SDK is emerging as one of the popular options for adding fingerprinting feature to applications. Not only does GrFinger SDK support over fifty different types of fingerprint readers, in addition it supports multiple types of fingerprinting features which cover areas of scanning, authentication, recognition and verification.

One of the major advantages of using the GrFinger SDK is that existing application teams just need to understand the features in the SDK and they can then program their specific fingerprinting requirements into their own applications. This results in significant cost savings as current infrastructure doesn’t need any upgradation as well there are no additional software purchase costs involved.

Another important feature of Griaule’s fingerprinting SDK is that it has separate releases for Microsoft and Java based libraries, thus supporting integration with both categories of applications at a binary level. While the Microsoft library is accessible through DLL and COM Components (Active X), the Java library is the standardized one which can be added as a dependency in any existing Java code. Java-based SDK has the added advantage of being Operating System neutral, as for any other Java application, and hence can be run on any Java supported operating systems such as Windows, Linux (including Gnu), MAC OS X as well as Android. In addition, the SDK comes with full-fledged documentation for bringing the developers up-to-speed with its SDK at a rapid pace, coupled with source code samples to show the SDK’s usage in code and topping it off with a demo application showcasing an across-the-layers usage of the SDK.

Griaule SDK Features

Biometrics anywhere

Windows and Linux.

Independence of sensor

Supports 50 different fingerprint readers.  Most fingerprint libraries provided by manufacturers only support their own devices.  Fingerprint SDK supports many fingerprint readers, allowing the developer, or End User, the ability to choose the reader most suitable for their needs.  Even after the application has been developed and/or deployed, Griaule Fingerprint SDK will let you change the fingerprint reader’s hardware without modifying your code.

Easy and intuitive

Fingerprint recognition libraries from other fingerprint SDKs only offer an interface in a hard to use dynamic link library (DLL).  For example, you have to create an import file for the specific language you are using.  Griaule Fingerprint SDK offers multiple interfaces in ActiveX, DLL, Java and .NET elements.

Use your preferred programming language

Fingerprint Software Development Kit also supports many programming languages such as Java, Delphi Visual Basic, FoxPro, C++, .NET,  Perl, PHP, ASP and many others.

The way you need it

Most solutions only offer a one-to-one match which can only be used for fingerprint verification purposes.  With Fingerprint recognition SDK you have unlimited one-to-many fingerprint matches, making it one of the very best biometric SDKs for fingerprint authentication.

Biometric data interchange and interoperability standards

Biometric SDK is compliant with ISO 19794-2 and ANSI 378-2004.

Quality worldwide

Biometric API is the most powerful technology behind thousands of biometric transactions performed daily.  It is used in government and civil programs in over 80 countries worldwide.

Easy licensing

In order to use Fingerprint matching SDK, you must use a product key to activate the licensed copy for every computer the software is installed on.  This can be easily done through an online activation procedure or by using a USB key and the Griaule License Manager.

30-Day Free Trial

You can download your free trial of Fingerprint SDK to create your applications and use it non-commercially for 30 days.  You will need to request a trial license online.  Once you decide to purchase SDK, you do not have to re-install the software.

Biometrics for all

Web and business growth for applications on stand-alone PCs, networking PCs, client-server based web applications or any other computer design.

ARM Processor Support

Fingerprint SDK can work on mobile devices & operating systems such as Android, Windows Mobile and Linux.  Please contact us for a quote.

Easy to learn

Fingerprint SDK supports multiple programming languages, and offers source code examples in programming languages that use the ActiveX component, Dynamic Link Library (DLL), Java packages, and .NET library.

Fingerprint template consolidation

Fingerprint API is designed to improve the recognition rate, the more often someone uses it and is recognized by the system; the more precise the registered biometric information becomes by improving the quality of the fingerprint template, thus reducing the database size and the identification time.

Outstanding fingerprint matching speed

Fingerprint authentication SDK has been rated as one of the fastest algorithms for fingerprint matching speed within the industry.  Biometric SDK is more than capable for the most demanding applications and saves you valuable time.

Griaule Tools

This is a support tool that runs as an icon in the system tray.  It shows useful information for technical support while providing online activation.

International merit

In 2003, Griaule Fingerprint SDK was tested by one of the world’s leading fingerprint recognition systems, NIST (National Institute of Standards & Technology) and successfully passed.

In 2006, GrFinger SDK was rated the best recognition algorithm across all fingerprint databases in the Fingerprint Verification Contest (FVC2006).

Ph.D. research team

The Griaule Biometrics team continually strives to improve the quality of the algorithms used with Fingerprint SDK. The team works continuously to increase the recognition rates and ensures that SDK is working with the latest versions of Windows & Linux operating systems.  The key members of this team have extensive knowledge and publications on image processing, computer vision and other related fields.

Driver-less Microsoft Fingerprint reader and Digital Persona support

Our SDK comes with its own driver for these readers and therefore you do not need the manufacturer’s drivers or SDK (API).
