The attacking technique uses the scores provided by the matcher to adapt a global distribution, computed from a development set of users, to the local specificities of the client being attacked. The proposed attack is evaluated on an Eigenfacebased verification system using the XM2VTS database. The results show a very high efficiency of the hill-climbing algorithm, which successfully bypassed the system for over 85\% of the attacked accounts.}, pdf = {https://publications.idiap.ch/attachments/papers/2009/Galbally_BIDS_2009.pdf} }
