Practical Auditing of Differentially Private Graph Release Mechanisms: Methodology, Toolkit, and Case Study
Nicholas D'Silva, Surya Nepal, Salil S. Kanhere
Differential Privacy (DP) has become a prominent approach for protecting graph data releases, yet empirical auditing methodologies have largely been developed for tabular datasets…
LLMs Anchor on Chief Complaint and Fail to Integrate Evidence in Sequential Clinical Triage
Dipankar Srirag, Haokai Zhao, Ashutosh Kumar +6
Triage in the emergency department (ED) is a sequential decision process that unfolds turn by turn. Existing evaluations of large language models (LLMs) for triage use completed re…
GuardianAgent: Policy-Conditioned Risk-Adaptive Anonymization with Verified Adversarial Escalation
Ruiyi Yang, Gayathri Lihinikaduarachchi, Rahat Masood +2
Privacy protection for live web traffic requires more than detecting private spans. Agent-based privacy protection systems must determine whether an outgoing action complies with t…
From Triage to Discharge: A Survey of NLP Tasks, Methods, and Open Challenges in the Emergency Department
Dipankar Srirag, Aditya Joshi, Salil Kanhere +1
Emergency departments (EDs) operate under time pressure, generating multimodal data such as clinical conversations, triage notes, and discharge documents. Recent advances in natura…
Beyond Attack Success Rate: Examining Trigger Leakage in Vision-Language Agentic Systems
Jiamin Chang, Salil Kanhere, Piotr Koniusz +3
Vision-Language Agentic Systems (VLAS) connect visual perception to planning, tool use, and physical actions. This means backdoor-type triggers can propagate through both decision…
GETA: Generalized Encrypted Traffic Analysis
Ransika Gunasekara, Rahat Masood, Salil Kanhere
Traditional traffic analysis is being fundamentally challenged by the rapid adoption of encryption, tunnelling, and privacy-preserving protocols, which increasingly obscure packet…
If you're waiting for a sign... that might not be it! Mitigating Trust Boundary Confusion from Visual Injections on Vision-Language Agentic Systems
Jiamin Chang, Minhui Xue, Ruoxi Sun +3
Recent advances in embodied Vision-Language Agentic Systems (VLAS), powered by large vision-language models (LVLMs), enable AI systems to perceive and reason over real-world scenes…
SoK: Practical Aspects of Releasing Differentially Private Graphs
Nicholas D'Silva, Surya Nepal, Salil S. Kanhere
Graph data is increasingly prevalent across domains, offering analytical value but raising significant privacy concerns. Edges may encode sensitive relationships, while node attrib…
TriageSim: A Conversational Emergency Triage Simulation Framework from Structured Electronic Health Records
Dipankar Srirag, Quoc Dung Nguyen, Aditya Joshi +2
Research in emergency triage is restricted to structured electronic health records (EHR) due to regulatory constraints on nurse-patient interactions. We introduce TriageSim, a simu…
Revisit Time Series Classification Benchmark: The Impact of Temporal Information for Classification
Yunrui Zhang, Gustavo Batista, Salil S. Kanhere
Time series classification is usually regarded as a distinct task from tabular data classification due to the importance of temporal information. However, in this paper, by perform…
Demystifying Trajectory Recovery From Ash: An Open-Source Evaluation and Enhancement
Nicholas D'Silva, Toran Shahi, Øyvind Timian Dokk Husveg +3
Once analysed, location trajectories can provide valuable insights beneficial to various applications. However, such data is also highly sensitive, rendering them susceptible to pr…
Modern Computing: Vision and Challenges
Sukhpal Singh Gill, Huaming Wu, Panos Patros +22
Over the past six decades, the computing systems field has experienced significant transformations, profoundly impacting society with transformational developments, such as the Int…
