Deep-Fake CAPTCHA: Mitigating Next-Generation Social Engineering Attacks
Guy Frankovits, Lior Yasur, Fred M. Grabovski +1
This paper presents DF-CAPTCHA, an active defense against real-time deepfake impersonation in voice and video calls. Instead of passively searching for artifacts, DF-CAPTCHA prompt…
LeakBoost: Perceptual-Loss-Based Membership Inference Attack
Amit Kravchik Taub, Fred M. Grabovski, Guy Amit +1
Membership inference attacks (MIAs) aim to determine whether a sample was part of a model's training set, posing serious privacy risks for modern machine-learning systems. Existing…
ASRJam: Human-Friendly AI Speech Jamming to Prevent Automated Phone Scams
Freddie Grabovski, Gilad Gressel, Yisroel Mirsky
Large Language Models (LLMs), combined with Text-to-Speech (TTS) and Automatic Speech Recognition (ASR), are increasingly used to automate voice phishing (vishing) scams. These sys…
Validation and Implementation of ILBFS
Fred Matanel Grabovski, Lior Yasur
Recursive Best-First Search (RBFS) is a heuristic search algorithm known for its efficient memory usage compared to traditional best-first search methods like A*. Despite its theor…
Back-in-Time Diffusion: Unsupervised Detection of Medical Deepfakes
Fred Grabovski, Lior Yasur, Guy Amit +1
Recent progress in generative models has made it easier for a wide audience to edit and create image content, raising concerns about the proliferation of deepfakes, especially in h…
DiffFinger: Advancing Synthetic Fingerprint Generation through Denoising Diffusion Probabilistic Models
Freddie Grabovski, Lior Yasur, Yaniv Hacmon +2
This study explores the generation of synthesized fingerprint images using Denoising Diffusion Probabilistic Models (DDPMs). The significant obstacles in collecting real biometric…
Deepfake CAPTCHA: A Method for Preventing Fake Calls
Lior Yasur, Guy Frankovits, Fred M. Grabovski +1
Deep learning technology has made it possible to generate realistic content of specific individuals. These `deepfakes' can now be generated in real-time which enables attackers to…
