Instructions

Dependencies

  • seaborn
  • numpy
  • pylab
  • matplotlib
  • argparse
  • csv

Usage

  1. Run evaluateMorphingVulnerability.py

    usage: evaluateMorphingVulnerability.py [-h] [--fmr [FMR]]
                                    	[--figureTitle [FIGURETITLE]]
                                    	[--legendLocation [LEGENDLOCATION]]
                                    	matedScoresFile nonMatedScoresFile
                                    	figureFile

Evaluate the vulnerability of biometric systems to attacks using morphed
biometric information.

positional arguments:
  matedScoresFile       filename for the mated scores
  nonMatedScoresFile    filename for the non-mated scores
  figureFile            filename for the output figure

optional arguments:
  -h, --help            show this help message and exit
  --fmr [FMR]           FMR in percentage of the verification threshold, if
                        none provided, FMR = 0.1 per cent
  --figureTitle [FIGURETITLE]
                        title for the output figure
  --legendLocation [LEGENDLOCATION]
                        legend location

  2. Input: at least 2 score files (mated and non-mated score examples provided), and the file name for the output figure, and optionally other parameters of the computation and the formatting of the figure.

    The score files contain the subject IDs being compared followed by the resulting comparison score, separated by blank spaces. They should be stored as a csv or text file, which will be processed with the csv package. Examples are provided.

  3. Output: figure with score distributions and resulting Pmorph.
