An Introduction to Vein Presentation Attacks and Detection
============================================================
This package is part of the signal-processing and machine learning toolbox
Bob_. It reproduces results presented in Chapter 18 of the "Handbook of
Biometric Anti- Spoofing: Presentation Attack Detection 2nd Edition".
Installation
------------
We use conda_ to manage the software stack installation. To install this
package and all dependencies, first install conda_, and then run the
following command on your shell::
$ conda create --name hobpad2-veins --override-channels -c https://www.idiap.ch/software/bob/conda -c defaults python=3 bob.hobpad2.veins
$ conda activate hobpad2-veins
(hobpad2-veins) $ #type all commands inside this "activated" environment
.. note::
At the present time, Bob_ only offers support to Linux and MacOS operating
systems. Windows installations are **not** supported.
This will install all the required software to reproduce this paper.
You now need to procure the raw data to run the experiments. Visit the web page
for the `VERA FingerVein`_ and click on the "Download" link on that page.
Follow the instructions to sign the End-User License Agreement (EULA) and then
you'll be able to access the package with the data. Download and uncompress it.
Annotate the directory leading to the root of the dataset. In this guide, we'll
refer to it using a generic path ``/path/to/verafinger``.
Once the data is downloaded and uncompressed, configure Bob_'s access to it by
editing (or creating) a file called ``${HOME}/.bob_bio_databases.txt`` and set
the path to the dataset there. Here is an example::
(hobpad2-veins) $ cat ~/.bob_bio_databases.txt
[YOUR_VERAFINGER_DIRECTORY] = /path/to/verafinger
You're now all set. Proceed to the instructions to re-run algorithms and
analysis routines available in this package.
Re-running Vulnerability Analysis
---------------------------------
To re-run results for vulnerability analysis, first run the baseline
experiments based on Maximum Curvature and Miura Matching using the `Vera
Fingervein`_ "Nom" Protocol::
(hobpad2-veins) $ verify.py mc_bio
(hobpad2-veins) $ verify.py mc_pa
This should take about 2 hours to complete in a modest computer. If you have
more cores available, it is adviseable to run the jobs in parallel. Just
execute it like this instead::
(hobpad2-veins) $ verify.py mc_bio parallel
Results are stored in the ``results`` folder, which is created if it doesn't
already exist. Then, run the analysis script to produce the vulnerability
analysis merit figures for the algorithm/protocol above::
(hobpad2-veins) $ bob vuln hist results/scores/mc/{Nom,Nom-va}/nonorm/scores-dev
The last script should produce a figure like Figure 10 in the book chapter,
together with error rates you can quote. Repeat the above analysis for other
protocols like the following, for the "Full" protocol::
(hobpad2-veins) $ verify.py --protocol='Full' mc_bio
(hobpad2-veins) $ verify.py --protocol='Full-va' mc_pa
There is a total of 4 different `Vera Fingervein`_ protocols supported: "Full",
"Nom" (the default), "Fifty" and "B". There is a total of 3 different baseline
algorithms that vary only on the feature extraction (binarisation) technique
used. All baselines use pre-annotated regions of interest pre-processing and
Miura Matching (correlation) for scoring: Maximum Curvature (configuration
``mc_bio``), Repeated Line Tracking (configuration ``rlt_bio``) and Wide-Line
Detector (configuration ``wld_bio``). You may refer to the documentation of
bob.bio.vein_ for details on the implementation. You can list available
baselines using the following command::
(hobpad2-veins) $ resources.py --types=config --packages=bob.hobpad2.veins
Once you ran all baselines, you should be able to reproduce Table 2 in the
book chapter.
For your reference, these are the EER values at the operation point:
+-----------------------+----------+-----------+-----------+
| **Protocol/Baseline** | **mc** | **rlt** | **wld** |
+-----------------------+----------+-----------+-----------+
| *Nom* | 2% | 19% | 7% |
+-----------------------+----------+-----------+-----------+
| *Full* | 1% | 11% | 4% |
+-----------------------+----------+-----------+-----------+
| *B* | 1% | 17% | 3% |
+-----------------------+----------+-----------+-----------+
| *Fifty* | 1% | 17% | 3% |
+-----------------------+----------+-----------+-----------+
This is Impostor Attack Presentation Match Rate (IAPMR) for thresholds on the
EER point for the baseline systems above:
+-----------------------+----------+-----------+-----------+
| **Protocol/Baseline** | **mc** | **rlt** | **wld** |
+-----------------------+----------+-----------+-----------+
| *Nom* | 83% | 38% | 76% |
+-----------------------+----------+-----------+-----------+
| *Full* | 89% | 34% | 80% |
+-----------------------+----------+-----------+-----------+
| *B* | 86% | 32% | 75% |
+-----------------------+----------+-----------+-----------+
| *Fifty* | 77% | 35% | 70% |
+-----------------------+----------+-----------+-----------+
Re-running Competition_ Baselines
---------------------------------
You can re-run the baseline algorithm for presentation-attack detection
provided by Idiap during "The 1st Competition_ on Counter Measures to Finger
Vein Spoofing Attacks", presented on ICB 2018. To do so, run::
(hobpad2-veins) $ #runs the FFT-based algorithm for the "full" PAD protocol
(hobpad2-veins) $ spoof.py -vv verafinger-pad fourier
(hobpad2-veins) $ # the same as above for the "cropped" protocol
(hobpad2-veins) $ spoof.py -vv --protocol=cropped verafinger-pad fourier
The above commands should get your scores in the directory ``results``. You may
then run the analysis, which will lead you to results reported in Figure 11 in
the book chapter (see the last two plots of each PDF)::
(hobpad2-veins) $ bob bio hist --output=idiap-full.pdf --eval results/scores/fourier/full/nonorm/scores-{dev,eval}
(hobpad2-veins) # The next line dumps a table with the calculated metrics
(hobpad2-veins) $ bob bio metrics --eval results/scores/fourier/full/nonorm/scores-{dev,eval}
Some of the results reported rely on scores provided by other teams that
participated on the competition_. Those scores are loaded from the folder
``scores`` available within this package. You can find the directory containing
the scores with the following command::
(hobpad2-veins) $ bob_hobpad2_veins_scores.py
Scores are located at /path/to/bob.hobpad2.veins/bob/hobpad2/veins/scores
(hobpad2-veins) $ ls -l /path/to/bob.hobpad2.veins/bob/hobpad2/veins/scores
total 0
drwxr-xr-x 6 foobar users 204 Apr 16 15:02 pad-competition/
drwxr-xr-x 10 foobar users 340 Apr 16 15:02 mc/
drwxr-xr-x 10 foobar users 340 Apr 16 15:02 rlt/
drwxr-xr-x 10 foobar users 340 Apr 16 15:02 wld/
Results from Table 3 in the book chapter can be reproduced with the following
script::
mkdir competition-results
SCORES_DIR=/path/to/bob.hobpad2.veins/bob/hobpad2/veins/scores
for participant in idiap guc blab grip-priamus; do
for protocol in full cropped; do
plotfname="competition-results/${participant}-${protocol}.pdf"
logfname="competition-results/${participant}-${protocol}.txt"
echo "PAD of '${participant}' on protocol '${protocol}' -> ${logfname}"
bob bio hist --output=${plotfname} --eval ${SCORES_DIR}/pad-competition/${participant}/${protocol}/scores-{dev,eval}
bob bio metrics --output=${plotfname} --eval ${SCORES_DIR}/pad-competition/${participant}/${protocol}/scores-{dev,eval}
done
done
By looking at all log files generated from the metrics commands, you should be
able to reconstruct the data on Table 1 relative to results published
alongside the 1st. Competition on Counter Measures to Fingervein Spoofing.
Results shown here correspond to the HTER on the test set for a threshold
chosen *a priori* on the development set EER (in parenthesis):
+--------------+-------------+-------------+-------------+------------------+
| **Protocol** | **Idiap** | **GUC** | **B-Lab** | **Grip-Priamus** |
+--------------+-------------+-------------+-------------+------------------+
| *full* | 0% ( 0%) | 4% (0%) | 0% (0%) | 0% (0%) |
+--------------+-------------+-------------+-------------+------------------+
| *cropped* | 19% (24%) | 3% (0%) | 1% (0%) | 0% (0%) |
+--------------+-------------+-------------+-------------+------------------+
Scores
------
To improve reproducibility aspects, we include all pre-generated scores after
running the systems described above, in the ``scores`` folder within this
package. The contents are the same as ``results/scores`` if you run all
variants described above. You may reproduce all analysis described in the book
chapter only by using them, instead of running all baseline scripts. To do so,
just replace the path on the relevant analysis command-line instructions above
from ``results/scores`` to ``/path/to/scores``, which may obtained with the
script ``bob_hobpad2_veins_scores.py`` as described above.
The scores sub-directory also contains de-anonymized scores provided by
competitors of our paper "The 1st Competition_ on Counter Measures to Finger
Vein Spoofing Attacks", presented on ICB 2018. You'll need these to reproduce
some of the figures shown in the book chapter. Notice we have not received
source code contributions for competitors and therefore cannot reproduce or
provide code to reproduce such results.
Extending Functionality
-----------------------
To extend functionality provided by this package, you'll need to develop new
components for either bob.bio.vein_ (our biometric vein recognition framework)
or bob.pad.vein_ (our presentation-attack detection framework for vein
recognition systems). Start by reading their user guides.
