MegaMatcher Accelerator Provides Large Biometric Database Management

Neurotechnology : 28 October, 2011  (New Product)
Operators of large biometric iris and fingerprint databases now have access to MegaMatcher Accelerator 4.0 from Neurotechnology for improved reliability and fault-tolerance
MegaMatcher Accelerator Provides Large Biometric Database Management
Neurotechnology has released MegaMatcher Accelerator 4.0, the latest update of the company’s multi-biometric software and hardware solution for high-volume, high-speed fingerprint and iris identification. MegaMatcher Accelerator 4.0 includes a larger database capacity, enhanced fault tolerance and a new matching algorithm that provides even greater accuracy, with extremely fast matching speeds of up to 100 million fingerprints per second – with a tolerance of 360 degrees of fingerprint rotation – and up to 200 million irises per second. Even at these high speeds, MegaMatcher Accelerator performs a full database search for each match (unlike systems that use internal database indexing or pre-classification); this eliminates potential false rejections from incorrect classifications and gives MegaMatcher Accelerator a very high degree of reliability.

MegaMatcher Accelerator 4.0 provides fast, accurate multi-biometric identification using both fingerprint and iris modes together, or either mode can be used as a primary form of identification. MegaMatcher Accelerator also can check identification results with other biometric data from any Neurotechnology-supported modality, including face, palmprint or voice identification. It can manage a database of up to 40 million fingerprints and 50 million irises with the Extended version and up to 4 million fingerprints and 5 million irises with the Standard version. For even higher volume applications, multiple MegaMatcher Accelerators can be connected in a cluster to manage databases with billions of records.

"MegaMatcher Accelerator 4.0 simplifies the development of large Automatic Biometrical Identification Systems (ABIS) while having even higher reliability than the previous version," said Antonello Mincone, project team leader for Neurotechnology. "This makes MegaMatcher Accelerator 4.0 an even more competitive solution for a wide number of national scale government projects, such as document issuance and voter de-duplication, as well as biometric applications for private sector uses including banking and healthcare."

MegaMatcher Accelerator 4.0 includes a number of significant enhancements over the previous version. The new fingerprint algorithm offers even higher reliability than the previous version: at the same False Acceptance Rate (FAR) level, the False Rejection Rate (FRR) is up to three times smaller. MegaMatcher Accelerator 4.0 does not require flushing – a specific procedure that periodically pauses the processing of identification requests to optimize internal data structures. By eliminating the need for flushing, MegaMatcher Accelerator 4.0 can operate without pauses, further enhancing overall speed and efficiency.

Enhanced fault tolerance in MegaMatcher Accelerator 4.0 ensures high availability through the use of secondary and/or parallel MegaMatcher Accelerators. The secondary MegaMatcher Accelerator keeps information on the state of the main Accelerator and is activated if the main Accelerator becomes unavailable due to network issues, a crash or other hardware problems. This allows the system to continue working. When parallel MegaMatcher Accelerators are used, there is automatic data synchronization between the parallel systems.

MegaMatcher Accelerator 4.0 is available in both Extended and Standard versions. System benchmarks for both MegaMatcher Accelerator 4.0 versions are among the fastest in the industry:

* MegaMatcher Accelerator 4.0 Extended Version offers the highest performance for applications that require extremely fast matching with a large volume of data. Working on an HP ProLiant DL360G7 server with 96GB RAM, MegaMatcher Accelerator 4.0 Extended can manage a database of up to 40 million fingerprints and perform 1:N matching at a speed of 100 million fingerprints per second; it can manage a database of up to 50 million irises and perform 1:N matching at a speed of 200 million irises per second.

* MegaMatcher Accelerator 4.0 Standard Version is a fast, cost-effective, PC-based solution for customers with smaller biometric applications. Working on a PC with an i7 processor, 12GB RAM, 1.5TB HDD, MegaMatcher Accelerator 4.0 Standard can manage databases of up to 5 million irises or 4 million fingerprints and can perform matching of up to 35 million fingerprints or 70 million irises per second.

MegaMatcher and MegaMatcher Accelerator technology is used in a wide variety of biometric solutions worldwide for election control, passport and visa documentation, border control, criminal investigations and duplicate searches in large-scale government and commercial databases. The MegaMatcher fingerprint recognition algorithm is NIST MINEX-compliant for use in US Government Personal Identity Verification (PIV) program fingerprint recognition applications and it supports most biometric industry standards.
