Fingerprint Matcher component

The Fingerprint Matcher performs fingerprint template matching in 1-to-1 (verification) and 1-to-many (identification) modes. Also the Fingerprint Matcher component includes fused matching algorithm that allows to increase template matching reliability by:

• matching templates that contain 2 or more fingerprint records (note that Fingerprint Segmenter or Fingerprint Client components are required to perform template extraction from images that contain more than one fingerprint);
• matching templates that contain fingerprint, face, voiceprint and/or iris records (note that matching faces, irises and voiceprints requires to purchase Face Matcher, Iris Matcher and Voice Matcher components correspondingly).

Technical specifications and reliability and performance tests contain information abour the template matching speeds and recognition quality in different scenarios.

One Fingerprint Matcher license is included with VeriFinger 6.5 Standard SDK, VeriFinger 6.5 Extended SDK, MegaMatcher 4.3 Standard SDK and MegaMatcher 4.3 Extended SDK. More licenses for this component can be purchased any time by VeriFinger 6.5 SDK and MegaMatcher 4.3 SDK customers.

Fast Fingerprint Matcher component

The Fast Fingerprint Matcher component is intended for the large-scale AFIS and biometric systems. The component includes a fast matching mode and also has the same matching mode as the regular Fingerprint Matcher.

Multi-biometric fused template matching can be achieved by combining the Fast Fingerprint Matcher component with Face, Voice and/or Iris Matchers (regular or fast versions of them can be used depending on project implementation).

See the reliability and performance testing results for the comparison of matching modes and multi-modal template matching.

One Fast Fingerprint Matcher license is included with MegaMatcher 4.3 Standard SDK. Two Fast Fingerprint Matcher licenses are included with MegaMatcher 4.3 Extended SDK. More licenses for this component can be purchased any time by MegaMatcher 4.3 SDK customers.

Fingerprint Client

The Fingerprint Client component is a combination of the Fingerpint Extractor, Fingerprint BSS, Fingerprint Segmenter and Fingerprint WSQ components. It is intended for the systems that need to support most or all functionality of the mentioned components on the same PC. Using these licenses allows to optimize component license costs as well as reduce license management.

Three non-concurrent licenses and one concurrent license for the Fingerprint Client component are included with VeriFinger 6.5 Extended SDK, MegaMatcher 4.3 Standard SDK and MegaMatcher 4.3 Extended SDK. More non-concurrent and concurrent licenses for this component can be purchased any time by VeriFinger 6.5 Extended SDK customers and MegaMatcher 4.3 SDK customers.

Fingerprint Extractor component

Fingerprint Extractor creates fingerprint templates from fingerprint images. Image quality control can be applied to accept only good quality fingerprint images.

The Fingerprint Extractor can generalize a fingerprint template from several images that contain the same fingerprint to improve the template's quality.

See technical specifications for the template extraction speed, the size of fingerprint template and the requirements for fingerprint image size and resolution.

One Fingerprint Extractor license is included with VeriFinger 6.5 Standard SDK, VeriFinger 6.5 Extended SDK, MegaMatcher 4.3 Standard SDK and MegaMatcher 4.3 Extended SDK. More licenses for this component can be purchased any time by VeriFinger 6.5 SDK and MegaMatcher 4.3 SDK customers.

Fingerprint Segmenter

The Fingerprint Segmenter components separates fingerprints if an image contains more than one fingerprint. This component enables Fingerprint Extractor component to process fingerprints from scanned tenprint card or image captured using scanners that allow to scan two or more fingers at once.

The component can be used from C/C++, C# and Java applications on all supported platforms. .NET wrappers of Windows libraries are provided for .NET developers.

The Fingerprint Segmenter licenses can be purchased anytime by VeriFinger 6.5 Extended SDK and MegaMatcher 4.3 SDK customers.

Fingerprint BSS (Biometric Standards Support)

The Fingerprint BSS component allows to integrate support for fingerprint template and image format standards and additional image formats with new or existing biometric systems based on VeriFinger SDK.

These biometric standards are supported:

• BioAPI 2.0 (ISO/IEC 19784-1:2006) (Framework and Biometric Service Provider for fingerprint identification engine)
• ISO/IEC 19794-2:2005 (Fingerprint Minutiae Data)
• ISO/IEC 19794-4:2005 (Finger Image Data)
• ANSI/INCITS 378-2004 (Finger Minutiae Format for Data Interchange)
• ANSI/INCITS 381-2004 (Finger Image-Based Data Interchange Format)
• ANSI/NIST-CSL 1-1993 (Data Format for the Interchange of Fingerprint, Facial, & SMT Information)
• ANSI/NIST-ITL 1a-1997 (Data Format for the Interchange of Fingerprint, Facial, & SMT Information)
• ANSI/NIST-ITL 1-2000 (Data Format for the Interchange of Fingerprint, Facial, & SMT Information)
• ANSI/NIST-ITL 1-2007 (Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information)
• ANSI/NIST-ITL 1a-2009 (Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information)

The Fingerprint BSS component allows conversion between Neurotechnology proprietary fingerprint templates, ISO/IEC 19794-2:2005, ANSI/INCITS 378-2004 and ANSI/NIST-ITL templates.

Fingerprint pattern classification module that allows to determine a fingerprint pattern class is included with Fingerprint BSS module. The classification is usually used in forensics, but also it can be used to increase fingerprint matching speed. The defined classes are:

• Left Slant Loop;
• Right Slant Loop;
• Tented Arch;
• Whorl;
• Scar;
• "Unknown" – for the nondetermined classes.

The Fingerprint BSS component also includes:

• JPEG 2000 image format support module with 1000 dpi Fingerprint Profile;
• NIST IHead image format support module;
• module with NIST Fingerprint Image Quality (NFIQ) algorithm, a standard method to determine fingerprint image quality.

Latent Fingerprint Editor is available with Fingerprint BSS component. In most cases automated image processing is unable to extract all minutiae or extracts a lot of false minutiae from latent fingerprint image (for example, taken from the crime scene). Therefore, an expert should manually edit a fingerprint template in order to submit it to an AFIS for the identification.
Sample latent fingerprint template editor (.NET) shows how to change minutia's coordinates, direction, type and other parameters.

The Fingerprint BSS component can be used from C/C++, C# and Java applications on all supported platforms. .NET wrappers of Windows libraries are provided for .NET developers.

Licenses for the Fingerprint BSS component can be purchased anytime by VeriFinger 6.5 Extended SDK and MegaMatcher 4.3 SDK customers.

Fingerprint WSQ

The Fingerprint WSQ component allows to integrate support for WSQ (Wavelet Scalar Quantization) image format. The WSQ format allows to compress a fingerprint image up to 10-15 times. WSQ compression process is "lossy", meaning that the reconstructed image is not equal to the original (some information is lost). However, the WSQ algorithm was specially designed to minimize the loss of fingerprint information therefore the reconstructed image is as close as possible to the original.

Neurotechnology's implementation of WSQ 3.1 fingerprint image compression was certified by the FBI as compliant with the accuracy requirements in the Wavelet Scalar Quantization (WSQ) Gray-Scale Fingerprint Image Compression Specification, Version 3.1.

The component can be used from C/C++, C# and Java applications on all supported platforms. .NET wrappers of Windows libraries are provided for .NET developers.

Licenses for the Fingerprint WSQ component can be purchased anytime by VeriFinger 6.5 Extended SDK and MegaMatcher 4.3 SDK customers.
