Textural features for fingerprint liveness detection
… biometrics and in particular the Fingerprint Liveness Detection (FLD), namely the recognition of fake fingerprints. Fingerprints spoofing is a topical issue as evidenced by the release of the latest iPhone and Samsung Galaxy models with an embedded fingerprint reader as an alternative to …

Adding liveness detection to the hand geometry scanner
… spoofed and shows the implementation of the live detection feature through an inexpensive but efficient electronic design.;The method used for detection is Photo-Plethysmography. The Reflectance Sensor built is of original conception. After amplifying, filtering and processing the sensor's signal, …

Surveying face liveness detection in the deepfake era
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-05-01

Security and Privacy Issues of Mobile Cyber-physical Systems
… we focus on three important topics: voice liveness detection, face forgery detection, and securing PIN-based authentication. In terms of attack systems, we study the location privacy in augmented reality (AR) applications. We first investigate the voice replay attacks on smartphones. Voice …

Development, Evaluation, and Analysis of Complex Eye Movement Biometrics
… not impossible), providing an inherent level of liveness detection and counterfeit-resistance. Further, recent advances in video-oculography allow for the efficient capture of eye movements from even low-quality image sensors, reducing the cost of entry and enabling integration with many existing …

Comparison of classification methods for perspiration-based liveness algorithm
… or in the worst case, dismembered fingers. Liveness, i.e. to determine whether the introduced biometric is coming from a live source, has been suggested as a means to circumvent attacks that use spoof fingers. It has been shown that water based casting materials and cadaver fingers were able …

A Framework to Detect Presentation Attacks
… presentation attacks. Feature from live Iris (or liveness detection) is a promising approach. Further, additional layer of security from iris feature can enable hardening the security of authentication system that existing works do not address. To address these limitations, this thesis proposed …

Static and dynamic analysis of near infra-red dorsal hand vein images for biometric applications
… in a spectrum to detect a major peak for liveness. A fake dorsal hand video was introduced for comparative studies. Experimental results showed that a respiratory like signal was detected as the main peak in the spectrum, verifying the vital signs of dynamic dorsal hand vein images and …

Fusion of fingerprint presentation attacks detection and matching: a real approach from the LivDet perspective
The liveness detection ability is explicitly required for current personal verification systems in many security applications. As a matter of fact, the project of any biometric verification system cannot ignore the vulnerability to spoofing or presentation attacks (PAs), which must be addressed by …

The Art of Fingerprint Spoofing
… sensors thus leading to the creation of Liveness Detector modules, capable of detecting the liveness of a fingerprint: from handcrafted methods to deep neural networks, the performances, tested on datasets of first editions of the LivDet competitions containing live prints and fake prints …

ML-CHIEFS: machine learning-based corneal-specular highlight imaging for enhancing facial recognition security
… including Deepfakes and identity thefts, liveness presentation attacks (PA), and master face dictionary attacks (MFDA). We propose countermeasures against facial biometric PAs, detect DeepFakes, and identify MFDA using intelligent ML-based specular highlights detections upon the hypothesis …
