Audiovisual Liveness Detection
2015Although multi-modal (e.g. voice and face) biometric verification systems were in active development and showed impressive performance they need to be protected from spoofing attacks. In this paper we present methods for verifying face liveness based on estimation of synchrony between audio stream and lips movements track during the pronunciation of ...

Improving FRET Detection in Living Cells
Molecular Imaging II, 2009Unambiguous FRET detection in living cells is often challenging. Here we describe how the advantages of fluorescence lifetime sensing with FLIM, fluorophore selection, and critical environmental controls provide better FRET detection.

Actively developing passive liveness detection
Biometric Technology Today, 2022When it comes to online verification, passive liveness detection (PLD) offers a superior user experience because it asks nothing of the customer. But not all PLD systems have the features needed to maximise their performance, says Jan Lunter of Innovatrics.

Iris Liveness Detection: A Survey
2018 IEEE Fourth International Conference on Multimedia Big Data (BigMM), 2018Iris is an accurate but vulnerable trait which is widely used in biometric system. To protect iris recognition module, an additional process called liveness detection is integrated into biometric system. The primary objective of this paper is to review the recent progress in iris liveness detection.

Living being presence detection system
The Journal of the Acoustical Society of America, 2009A system for distinguishing between a first condition corresponding to a living subject being directly in contact with an object of interest, and a second condition corresponding to the absence of contact between the living subject and the object of interest.

Correlation based fingerprint liveness detection
2015 International Conference on Biometrics (ICB), 2015Fingerprint recognition systems are vulnerable to spoof attacks, which consist in presenting forged fingerprints to the sensor. Typical anti-spoofing mechanism is fingerprint liveness detection. Existing liveness detection methods are still not robust to spoofing materials, datasets and sensor variations.

Experimental Results on Fingerprint Liveness Detection
2012Fingerprint liveness detection is aimed to detect if a fingerprint image, sensed by an electronic device, belongs to an "alive" fingertip or to be an artificial replica of it. Recent studies have shown that a fingerprint can be replicated and, if a clever attacker tries to evade the system, this is an issue.

Survey on fingerprint liveness detection
2013 International Workshop on Biometrics and Forensics (IWBF), 2013Recent researches have shown great attention in biometric systems due to the importance of its applications and its challenges. Researchers proved that the available fingerprint recognition systems are vulnerable to attack at sensor level. Thus, developing an efficient algorithm to protect fingerprint systems from imposer access is urgent.
