Web traffic has evolved to include both human users and automated agents, ranging from benign web crawlers to adversarial scanners such as those capable of credential stuffing, com…
The Privacy-Utility Tradeoff in Rank-Preserving Dataset Obfuscation
Mahshad Shariatnasab, Farhad Shirani, S. Sitharma Iyengar
Dataset obfuscation refers to techniques in which random noise is added to the entries of a given dataset, prior to its public release, to protect against leakage of private inform…
Privacy Limits in Power-Law Bipartite Networks under Active Fingerprinting Attacks
M. Shariatnasab, F. Shirani, Z. Anwar
This work considers the fundamental privacy limits under active fingerprinting attacks in power-law bipartite networks. The scenario arises naturally in social network analysis, tr…
Fundamental Privacy Limits in Bipartite Networks under Active Attacks
Mahshad Shariatnasab, Farhad Shirani, Elza Erkip
This work considers active deanonymization of bipartite networks. The scenario arises naturally in evaluating privacy in various applications such as social networks, mobility netw…
On Graph Matching Using Generalized Seed Side-Information
Mahshad Shariatnasab, Farhad Shirani, Siddharth Garg +1
In this paper, matching pairs of stocahstically generated graphs in the presence of generalized seed side-information is considered. The graph matching problem emerges naturally in…
