LBP - TOP Based Countermeasure against Face Spoofing Attacks
نویسندگان
چکیده
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%.

Detection of Video-Based Face Spoofing Using LBP and Multiscale DCT
Despite the great deal of progress during the recent years, face spoofing detection is still a focus of attention. In this paper, an effective, simple and time-saving countermeasure against video-based face spoofing attacks based on LBP (Local Binary Patterns) and multiscale DCT (Discrete Cosine Transform) is proposed. Adopted as the low-level descriptors, LBP features are used to extract spati...

متن کاملEfficient software attack to multimodal biometric systems and its application to face and iris fusion
In certain applications based on multimodal interaction it may be crucial to determine not only what the user is doing (commands), but who is doing it, in order to prevent fraudulent use of the system. The biometric technology, and particularly the multimodal biometric systems, represent a highly efficient automatic recognition solution for this type of applications. Although multimodal biometr...

With the wide deployment of face recognition systems in applications from border control to mobile device unlocking, the combat of face spoofing attacks requires increased attention; such attacks can be easily launched via printed photos, video replays and 3D masks. We address the problem of facial spoofing detection against replay attacks based on the analysis of aliasing in spoof face videos....
متن کاملFace Liveness Detection Using Dynamic Local Ternary Pattern (DLTP)
Face spoofing is considered to be one of the prominent threats to face recognition systems. However, in order to improve the security measures of such biometric systems against deliberate spoof attacks, liveness detection has received significant recent attention from researchers. For this purpose, analysis of facial skin texture properties becomes more popular because of its limited resource r...
