|Title:||Lbp-top Based Countermeasure Against Face Spoofing Attacks|
|Author:||De Freitas Pereira T.|
De Martino J.M.
|Abstract:||User authentication is an important step to protect information and in this field face biometrics is advantageous. Face biometrics is natural, easy to use and less human-invasive. Unfortunately, recent work has revealed that face biometrics is vulnerable to spoofing attacks using low-tech cheap equipments. This article presents a countermeasure against such attacks based on the LBP-TOP operator combining both space and time information into a single multiresolution texture descriptor. Experiments carried out with the REPLAY ATTACK database show a Half Total Error Rate (HTER) improvement from 15.16% to 7.60%. © 2013 Springer-Verlag.|
