FedComm: Federated Learning as a Medium for Covert Communication

no code implementations21 Jan 2022 Dorjan Hitaj, Giulio Pagnotta, Briland Hitaj, Fernando Perez-Cruz, Luigi V. Mancini

Proposed as a solution to mitigate the privacy implications related to the adoption of deep learning, Federated Learning (FL) enables large numbers of participants to successfully train deep neural networks without having to reveal the actual private training data.

Capture the Bot: Using Adversarial Examples to Improve CAPTCHA Robustness to Bot Attacks

no code implementations30 Oct 2020 Dorjan Hitaj, Briland Hitaj, Sushil Jajodia, Luigi V. Mancini

To this date, CAPTCHAs have served as the first line of defense preventing unauthorized access by (malicious) bots to web-based services, while at the same time maintaining a trouble-free experience for human visitors.

EnCoD: Distinguishing Compressed and Encrypted File Fragments

no code implementations15 Oct 2020 Fabio De Gaspari, Dorjan Hitaj, Giulio Pagnotta, Lorenzo De Carli, Luigi V. Mancini

To address this issue, we design EnCoD, a learning-based classifier which can reliably distinguish compressed and encrypted data, starting with fragments as small as 512 bytes.
