Large-scale AFIS and multi-biometric identification
MegaMatcher is designed for large-scale AFIS and multi-biometric systems developers. The technology ensures high reliability and speed of biometric identification even when using large databases.
Available as a software development kit that allows development of large-scale single- or multi-biometric fingerprint, iris, face, voice or palm print identification products for Microsoft Windows, Linux, macOS, iOS and Android platforms.
Mobile Fingerprint Client component
The Mobile Fingerprint Client component performs fingerprint template creation from images with additional fingerprint image segmentation. It also provides functionality for fingerprint template and image formats support based on biometric standards, as well as advanced image formats support.
The component is designed to be run on ARM Linux or Android or iOS devices. The Android devices should based on at least Snapdragon S4 system-on-chip (Krait 300 processor with 4 cores running at 1.51 GHz).
The component extracts a single fingerprint template in 1.2 seconds.
Proprietary image quality control may be applied to accept only good quality fingerprint images.
The Mobile Fingerprint Client can generalize a fingerprint template from several images that contain the same fingerprint to improve the template's quality.
The fingerprint image segmentation module is used to separate fingerprints if an image contains more than one fingerprint, . This functionality enables the Mobile Fingerprint Client component to process fingerprints from scanned tenprint card or image captured using scanners that allow to scan two or more fingers at once.
Fingerprint pattern classification module is included with the Fingerprint Client component to determine a fingerprint pattern class. The classification is usually used in forensics, but it also may be used to increase fingerprint matching speed. The defined classes are:
- Left Slant Loop;
- Right Slant Loop;
- Tented Arch;
- "Unknown" – for the nondetermined classes.
The component allows to integrate support for fingerprint template and image format standards with new or existing biometric systems based on MegaMatcher SDK. These formats and standards are supported:
- Neurotechnology proprietary fingerprint template format

- CBEFF V3.0 (ISO/IEC 19785-3:2015) (Common Biometric Exchange Formats Framework)

- 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)
- ANSI/NIST-ITL 1-2011 (Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information)
- ANSI/NIST-ITL 1-2011 Update:2013 Edition 2 (Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information)
- ANSI/NIST-ITL 1-2011 Update:2015 (Data Format for the Interchange of Fingerprint, Facial, & Other Biometric Information)
The component allows conversion between Neurotechnology proprietary fingerprint templates, ISO/IEC 19794-2:2005, ISO/IEC 19794-2:2011, ANSI/INCITS 378-2004, ANSI/INCITS 378-2009 and ANSI/NIST-ITL templates.
The component also includes support modules for advanced image formats:
- JPEG 2000 image format support module with 1000 ppi Fingerprint Profile;
- NIST IHead image format support module;
- module with NIST Fingerprint Image Quality (NFIQ) algorithm, a standard method to determine fingerprint image quality.
WSQ (Wavelet Scalar Quantization) image format module allows to compress a fingerprint image up to 10-15 times, as well as read images in this format.
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.
Three licenses for the Mobile Fingerprint Client component are included with MegaMatcher 11.2 Standard and Extended SDK. The licenses can be used on Android, iOS or ARM Linux platform. More licenses for this component can be purchased any time by MegaMatcher 11.2 SDK customers.
