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…
Single-Component Privacy Guarantees in Helper Data Systems and Sparse Coding with Ambiguation
Behrooz Razeghi, Taras Stanko, Boris Škorić +1
We investigate the privacy of two approaches to (biometric) template protection: Helper Data Systems and Sparse Ternary Coding with Ambiguization. In particular, we focus on a priv…
Privacy-Preserving Identification via Layered Sparse Code Design: Distributed Servers and Multiple Access Authorization
Behrooz Razeghi, Slava Voloshynovskiy, Sohrab Ferdowsi +1
We propose a new computationally efficient privacy-preserving identification framework based on layered sparse coding. The key idea of the proposed framework is a sparsifying trans…
Sparse Ternary Codes for similarity search have higher coding gain than dense binary codes
Sohrab Ferdowsi, Slava Voloshynovskiy, Dimche Kostadinov +1
This paper addresses the problem of Approximate Nearest Neighbor (ANN) search in pattern recognition where feature vectors in a database are encoded as compact codes in order to sp…
On Multiple Hypothesis Testing with Rejection Option
Naira Grigoryan, Ashot Harutyunyan, Svyatoslav Voloshynovskiy +1
We study the problem of multiple hypothesis testing (HT) in view of a rejection option. That model of HT has many different applications. Errors in testing of M hypotheses regardin…
