The 2nd Competition on Counter Measures to 2D Face Spoofing Attacks

Sébastien Marcel, André Anjos, Ivana Chingovska

As a crucial security problem, anti-spoofing in biometrics, and particularly for the face modality, has achieved great progress in the recent years. Still, new threats arrive in form of better, more realistic and more sophisticated spoofing attacks. The ob ...

Complementary Countermeasures for Detecting Scenic Face Spoofing Attacks

Sébastien Marcel, André Anjos

The face recognition community has finally started paying more attention to the long-neglected problem of spoofing attacks. The number of countermeasures is gradually increasing and fairly good results have been reported on the publicly available databases ...

Is the Network Turing-Complete?

Dejan Kostic, Peter Peresini

Ensuring correct network behavior is hard. This is the case even for simple networks, and adding middleboxes only complicates this task. In this paper, we demonstrate a fundamental property of networks. Namely, we show a way of using a network to emulate t ...

LBP-TOP based countermeasure against face spoofing attacks

Sébastien Marcel, André Anjos, Tiago De Freitas Pereira

User authentication is an important step to protect information and in this eld 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 ...

On the Effectiveness of Local Binary Patterns in Face Anti-spoofing

Sébastien Marcel, André Anjos, Ivana Chingovska

Spoofing attacks are one of the security traits that biometric recognition systems are proven to be vulnerable to. When spoofed, a biometric recognition system is bypassed by presenting a copy of the biometric evidence of a valid user. Among all biometric ...

Optinal Source-Based Filtering of Malicious Traffic

In this paper, we consider the problem of blocking malicious traffic on the Internet via source-based filtering. In particular, we consider filtering via access control lists (ACLs): These are already available at the routers today, but are a scarce resour ...

Counter-Measures to Photo Attacks in Face Recognition: a public database and a baseline

Sébastien Marcel, André Anjos

A common technique to by-pass 2-D face recognition systems is to use photographs of spoofed identities. Unfortunately, research in counter-measures to this type of attack have not kept-up - even if such threats have been known for nearly a decade, there se ...

Routing Attacks as a Viable Threat: Can Software Systems Protect Themselves?

Dan Alistarh

In this paper, we show that distributed systems are vul- nerable to routing attacks and propose an architecture to obviate this vulnerability. A somewhat surprising finding is that even a small-scale routing attack can completely dis- rupt the operation of ...

Intrusion Detection System Resiliency to Byzantine Attacks: The Case Study of Wormholes in OLSR

Georgios Theodorakopoulos

In this paper we extend the work presented in [1], [2] by quantifying the effects of in-band wormhole attacks on Intrusion Detection Systems. More specifically, we propose a mathematical framework for obtaining performance bounds of Byzantine attackers and ...
