Machine learning attack on copy detection patterns: are 1x1 patterns cloneable?

Roman Chaban, Olga Taran, Joakim Tutt +3

Nowadays, the modern economy critically requires reliable yet cheap protection solutions against product counterfeiting for the mass market. Copy detection patterns (CDP) are consi…

Mobile authentication of copy detection patterns: how critical is to know fakes?

Olga Taran, Joakim Tutt, Taras Holotyak +3

Protection of physical objects against counterfeiting is an important task for the modern economies. In recent years, the high-quality counterfeits appear to be closer to originals…

Variational Leakage: The Role of Information Complexity in Privacy Leakage

Amir Ahooye Atashin, Behrooz Razeghi, Deniz Gündüz +1

We study the role of information complexity in privacy leakage about an attribute of an adversary's interest, which is not known a priori to the system designer. Considering the su…

Privacy-Preserving Near Neighbor Search via Sparse Coding with Ambiguation

Behrooz Razeghi, Sohrab Ferdowsi, Dimche Kostadinov +2

In this paper, we propose a framework for privacy-preserving approximate near neighbor search via stochastic sparsifying encoding. The core of the framework relies on sparse coding…

On Perfect Obfuscation: Local Information Geometry Analysis

Behrooz Razeghi, Flavio. P. Calmon, Deniz Gunduz +1

We consider the problem of privacy-preserving data release for a specific utility task under perfect obfuscation constraint. We establish the necessary and sufficient condition to…

Privacy-Preserving Image Sharing via Sparsifying Layers on Convolutional Groups

Sohrab Ferdowsi, Behrooz Razeghi, Taras Holotyak +2

We propose a practical framework to address the problem of privacy-aware image sharing in large-scale setups. We argue that, while compactness is always desired at scale, this need…
