Getting Started
1.1 The GBS Fingerprint SDK The GBS Fingerprint SDK is a fingerprint recognition library that comes packaged with a Software Development Kit (SDK), allowing you to integrate biometrics in a wide range of applications. Thanks to its support for several programming languages, code samples, and its documentation, you'll start developing your application in a matter of minutes.
1.2 Installing the SDK 1.2.1 Licensing The GBS Fingerprint SDK requires a software license to work correctly. It is distributed with a trial license valid for 90 days*. After this period a license must be purchased by sending an email to
[email protected] and must be installed in C:\ProgramData\Griaule. For questions, please contact the Griaule Biometrics support sending an email to
[email protected].

1.2.5 Programming Language Support GBS Fingerprint SDK supports multiple programming languages, including Java, C++ and C# / .NET.
1.3 Features 1.3.1 Technical Characteristics Capture:
7
Detects fingerprint readers plug/unplug;
Automatic finger detection;
Supports BMP files for fingerprint image saving/loading;
Maximum image size of 1280 x 1280 pixels;
Minimum image size of 50 x 50 pixels;
Maximum resolution of 1000 DPI;
Minimum resolution of 125 DPI;
Extraction:
Average extraction time of 100ms 1;
Maximum image size of 500 x 500 pixels 2;
Minimum image size of 50 x 50 pixels;
Average template size of 400 bytes;
Matching 3:
Verification speed: up to 100/s 4.
Notes: 1. Images of 300 x 300 pixels. Machine: Pentium4 2.8GHz, 512MB RAM. 2. Larger images are cropped. 3. The Identification one-to-many is not performed by the GBS Fingerprint SDK. 4. Images of 100 x 100 pixels. Machine: Pentium4 2.8GHz, 512MB RAM.
1.3.2 Threshold and Rotation Tolerance The verification function in Fingerprint SDK library are governed by two important parameters: threshold and rotation tolerance. The threshold is the minimum score needed to state that two fingerprints do match. The default value is 20 for the verification process, ensuring a 1% FRR. The rotation tolerance defines the maximum acceptable angle variation (in degrees) between two fingerprints being compared that will result in a match. This value is valid in both clockwise and counterclockwise directions, so the maximum value that can be set is 180. The default value is 180.
1.4 What’s New on Fingerprint SDK
Added AFIS (Automatic Fingerprint Identification System) functionality: patterns are identified by software in fingerprint images and are used for comparison with another fingerprint image patterns to determine if they came from the same finger and ultimately, from the same person.
8
Added converter to WSQ functionality. The WSQ is the best image format for fingerprints. It reaches a great compression with high image quality.
Image formats supported when converting to WSQ: BMP, JPEG, JPEG 2000, TIFF, GIF and PNG.
9
Added support to more Fingerprint Readers;
Added support to Windows 7, 8 and 8.1 32-bit and 64-bit.
Fixed some bugs from the Fingerprint SDK 2009;
Dropped the concept of Context;
Dropped the editions IDENTIFICATION and VERIFICATION;
Does not perform multi-thread operations such as identification one-to-many;
Performs fingerprint extraction and verification (matching one-to-one).
2 How to migrate from the Fingerprint SDK 2009 to the new GBS Fingerprint SDK This section highlights the main differences introduced when comparing the new Fingerprint SDK and the Fingerprint SDK 2009.
2.1 The GBS Fingerprint SDK In the Fingerprint SDK 2009, a MatchingContext object is where the biometric operations (fingerprint minutiae extraction and fingerprint matching) occur. All methods in a MatchingContext object are synchronized, thus to execute N biometric operations at the same time, N MatchingContext objects must be created. In the new Fingerprint SDK, the Matching Context is not applicable anymore. The application continues to be thread-safe, but only single-threaded operations are performed at a time. For multi-thread operations, such as Identification (one-to-many), the GBS Server is needed. For further information regarding this software of the Griaule Biometric Suite, please contact the Griaule Biometrics support (
[email protected]).
2.1.1 New API: discontinued and new methods The following tables match the discontinued methods of the previous softwares (Fingerprint SDK 2009, AFIS 2.0 and WSQ 1.2) with the new ones that replace them, if applicable. The value NA indicates that the method's functionality has been discontinued in the current release of the SDK.

12
2.1.1.1 Methods Signature Simplified: Gr_IMAGE and Gr_TEMPLATE In the Fingerprint SDK 2009, several primitive types must be passed as parameters of the API functions in order to define an image or a template. In the GBS Fingerprint SDK, new classes define how Image and Template data must be defined. They encapsulate the necessary information and allow a clearer understanding of the API.
