Algorithms:

• Iris engine now features all quality improvements in iris templates extracted using Neurotec Biometric 12.2 SDK.
• Changed default configuration value to convert fingerprint templates to small representation when loading to memory. This results in significantly less RAM usage while not having noticeable impact on accuracy in most cases.

New features:

• Parallel database operations now supported. This can be useful for some ODBC databases which are optimized for multiple concurrent operations.

Fixes:

• Small fixes in webconfig.

Updates and improvements:

• Extended and improved template replication in memory functionality useful for high availability.
• Reduced memory usage in replicated mode.

Fixes:

• Fixed a bug with no database node failing reloading in presence of delete operations.
• Fixed issues in federation mode to properly handle additional connections.

Updates and improvements:

• Loading batch size now is controlled through parameters.

Fixes:

• Fixed the bug which caused failure to insert when palmprints used together with other modalities.
• Fixed several issues in WebConfig UI .

Updates and improvements:

• Increased accelerated faces speed.
• Decreased fingerprint memory usage for previous line templates.

The first release of MegaMatcher Accelerator 12.

Algorithms:

• Fingerprint, face and iris matching engines in the MegaMatcher Accelerator 12.0 Extreme edition now do not require GPU for reaching the highest matching speed. This greatly simplifies deployment without requiring installation of special hardware.
• The fingerprint matching algorithm now provides even higher accuracy, proven by the first place in NIST MINEX III, NIST PFT III and FVC-onGoing fingerprint algorithm evaluations.
• The face matching algorithm now provides higher accuracy.
• The iris matching engine now matches 1.2 Billion irises per second on a single server in the MegaMatcher 12.0 Extreme edition (same speed as for fingerprint and face engines).
