Experimental Protocol
Due to the wide variety of current liveness detection algorithms, the competition
defines some constraints for the submitted algorithms:
1) Methods must output, for each image, a “liveness degree” ranging from 0 to 100
(e.g. Posterior probability of “true” class).
2) A training set of fake and live fingerprint images will be made available to each
participant, freely downloadable from the LFC site after the participant
registration. These images are a small subset of the evaluation data set.
3) Each submitted algorithm, as a Win32 console application, must follow the input
and output sequence explained in this site.
The competition is open to academic and industrial institutions. Each user will
receive, after his registration and information about the competition rules, a
password to enter into the site and manage his/her personal information and uploaded
files. In order to finalize the registration, it is necessary to fill the license agreement
of the data set use. The filled and signed agreement must be sent through fax and by
mail.
Once a signed consent form is obtained, a link for downloading the training set will
be given.
Each participant must give their preference on whether to enter as anonymous. All
results will be included in the final report, in regard to the anonymity of the
participant.
With regard to this aspect, it is worth to point out that results published at
LivDet2009 cannot be used for commercial purposes. The goal of the competition
is merely to demonstrate the state-of-the-art.
