antispoofing.evaluation 2.0.0

This package provides methods for evaluation of biometric verification systems under spoofing attacks. The evaluation is based on the Expected Performance and Spoofability Curve (EPSC). Using this package, you can compute thresholds based on EPSC, compute various error rates and plot various curves related to EPSC.

Besides providing methods for plotting EPSC within your own scripts, this package brings several scripts that you can use to evaluate your own verification system (fused with an anti-spoofing system or not) from several perspectives. For example, you can:

• evaluate the threshold of a classification system on the development set

• apply the threshold on an evaluation or any other set to compute different error rates

• plot score distributions

• plot different performance curves (DET, EPC and EPSC)

Furthermore, you can generate hypothetical data and use them to exemplify the above mentioned functionalities.
