Stanisław Ciszkiewicz, Artur Janicki
The growing need for secure and convenient authentication methods has led to the increasing popularity of biometric solutions. In addition to traditional and popular methods, such…
Can We Use Probing to Better Understand Fine-tuning and Knowledge Distillation of the BERT NLU?
Jakub Hościłowicz, Marcin Sowański, Piotr Czubowski +1
In this article, we use probing to investigate phenomena that occur during fine-tuning and knowledge distillation of a BERT-based natural language understanding (NLU) model. Our ul…

"The Good, The Bad And The Ugly": Evaluation of Wi-Fi Steganography
Krzysztof Szczypiorski, Artur Janicki, Steffen Wendzel
In this paper we propose a new method for the evaluation of network steganography algorithms based on the new concept of "the moving observer". We considered three levels of undete…
Steganalysis of Transcoding Steganography
Artur Janicki, Wojciech Mazurczyk, Krzysztof Szczypiorski
TranSteg (Trancoding Steganography) is a fairly new IP telephony steganographic method that functions by compressing overt (voice) data to make space for the steganogram by means o…
Influence of Speech Codecs Selection on Transcoding Steganography
Artur Janicki, Wojciech Mazurczyk, Krzysztof Szczypiorski
The typical approach to steganography is to compress the covert data in order to limit its size, which is reasonable in the context of a limited steganographic bandwidth. TranSteg…
