Dictionary Attacks on Speaker Verification

Mirko Marras, Pawel Korus, Anubhav Jain +1

In this paper, we propose dictionary attacks against speaker verification - a novel attack vector that aims to match a large fraction of speaker population by chance. We introduce…

Hard-Attention for Scalable Image Classification

Athanasios Papadopoulos, Paweł Korus, Nasir Memon

Can we leverage high-resolution information without the unsustainable quadratic complexity to input scale? We propose Traversal Network (TNet), a novel multi-scale hard-attention a…

Empirical Evaluation of PRNU Fingerprint Variation for Mismatched Imaging Pipelines

Sharad Joshi, Pawel Korus, Nitin Khanna +1

We assess the variability of PRNU-based camera fingerprints with mismatched imaging pipelines (e.g., different camera ISP or digital darkroom software). We show that camera fingerp…

FiFTy: Large-scale File Fragment Type Identification using Neural Networks

Govind Mittal, Pawel Korus, Nasir Memon

We present FiFTy, a modern file type identification tool for memory forensics and data carving. In contrast to previous approaches based on hand-crafted features, we design a compa…

Neural Imaging Pipelines - the Scourge or Hope of Forensics?

Pawel Korus, Nasir Memon

Forensic analysis of digital photographs relies on intrinsic statistical traces introduced at the time of their acquisition or subsequent editing. Such traces are often removed by…

Content Authentication for Neural Imaging Pipelines: End-to-end Optimization of Photo Provenance in Complex Distribution Channels

Pawel Korus, Nasir Memon

Forensic analysis of digital photo provenance relies on intrinsic traces left in the photograph at the time of its acquisition. Such analysis becomes unreliable after heavy post-pr…

Large-Scale and Fine-Grained Evaluation of Popular JPEG Forgery Localization Schemes

Pawel Korus

Over the years, researchers have proposed various approaches to JPEG forgery detection and localization. In most cases, experimental evaluation was limited to JPEG quality levels t…

Correction Trees as an Alternative to Turbo Codes and Low Density Parity Check Codes

Jarosław Duda, Paweł Korus

The rapidly improving performance of modern hardware renders convolutional codes obsolete, and allows for the practical implementation of more sophisticated correction codes such a…
