Part 2: System Performance Evaluation

Laboratory staff will systematically attempt to spoof the system and also collect corresponding live data

• 500 live attempts from 50 people
• 500 attempts for five different materials (three known methods: Play-Doh, gelatin, silicon; two unspecified methods)
• Same finger molds will be used for all systems. New casts will be made for each system where degradation in spoof sample is seen after multiple placements (e.g. Play-Doh, gelatin).

The parameters adopted for the performance evaluation will be the following:

Evaluation per system

• Frej_n: Rate of failure to enroll for the system
• Fcorrlive_n: Rate of correctly classified live fingerprints for system
• Fcorrfake_n: Rate of correctly classified fake fingerprints for system
• Ferrlive_n: Rate of misclassified live fingerprints for system
• Ferrfake_n: Rate of misclassified fake fingerprints system
• ET: Average processing time per image
• MAM: Max. Allocated Memory while the algorithm is running

Rates are based on the assumption of a threshold of 50. Quality and match scores will be computed based on the collected images to support efforts to maintain fairness between the submitted systems.

Declaration of the Winner

• The winner will be awarded based on minimum overall classification error. Only one winner will be awarded.
