Hand Vein Spoof GANs: Pitfalls in the Assessment of Synthetic Presentation Attack Artefacts
IH&MMSec '23: Proceedings of the 2023 ACM Workshop on Information Hiding and Multimedia SecurityPages 133–138https://doi.org/10.1145/3577163.3595107I2I translation techniques for unpaired data are used for the creation of biometric presentation attack artefact samples. For the assessment of these synthetic samples, we analyse their behaviour when attacking hand vein recognition systems, comparing ...

First Learning Steps to Recognize Faces in the Noise
IH&MMSec '23: Proceedings of the 2023 ACM Workshop on Information Hiding and Multimedia SecurityPages 139–144https://doi.org/10.1145/3577163.3595105A UNet-type encoder-decoder inpainting network is applied to weaken the protection strength of selectively encrypted face samples. Based on visual assessment, FaceQNet quality, and ArcFace recognition accuracy the strategy is shown to be successful, ...

On the Feasibility of Post-Mortem Hand-Based Vascular Biometric Recognition
IH&MMSec '23: Proceedings of the 2023 ACM Workshop on Information Hiding and Multimedia SecurityPages 121–126https://doi.org/10.1145/3577163.3595096Recently, there is a growing interest to employ biometrics in post-mortem forensics, mainly to replace cost intensive radiology based imaging devices. While it has been shown that post-mortem biometric recognition is feasible for fingerprints, face and ...
