FORGETMARK: STEALTHY FINGERPRINT EMBEDDING VIA TARGETED UNLEARNING IN LANGUAGE MODELS

ICASSP 2026poster

Existing invasive (backdoor) fingerprints suffer from high-perplexity triggers that are easily filtered, fixed response patterns exposed by heuristic detectors, and spurious activations on benign inputs. We introduce \textsc{ForgetMark}, a stealthy fingerprinting framework that encodes provenance vi…

Understanding PII Leakage in Large Language Models: A Systematic Survey

IJCAI 2025

Large Language Models (LLMs) have demonstrated exceptional success across a variety of tasks, particularly in natural language processing, leading to their growing integration into numerous facets of daily life. However, this widespread deployment has raised substantial privacy concerns, especially

Unlocking the Effectiveness of LoRA-FP for Seamless Transfer Implantation of Fingerprints in Downstream Models

EMNLP 2025

With the rapid development of large language models (LLMs), protecting intellectual property (IP) has become increasingly crucial. To tackle high costs and potential contamination in fingerprint integration, we propose LoRA-FP, a lightweight plug-and-play framework that encodes backdoor fingerprints

SMMA-Net: An Audio Clue-Based Target Speaker Extraction Network with Spectrogram Matching and Mutual Attention

ICASSP 2024accepted

We propose a deep neural network with spectrogram matching and mutual attention (SMMA-Net) for audio clue-based target speaker extraction (TSE). To effectively use the auxiliary speech, we proposed spectrogram matching (SM) strategy and mutual attention (MA) block. We conducted all experiments on th…

A Large-Scale Pretrained Deep Model for Phishing URL Detection

ICASSP 2023accepted

Phishing attacks have always been a security issue that has attracted great attention in the cyber security community. Recently, the famous pre-trained models is being used as an anti-phishing solution. However, existing studies either simply transfer models pre-trained on text to phishing detection…

A Multi-Scale Feature Aggregation Based Lightweight Network for Audio-Visual Speech Enhancement

ICASSP 2023accepted

Audio-visual speech enhancement (AVSE) was shown to be superior over conventional audio-only counterpart for improving the speech quality. However, most existing AVSE models are heavyweight in the sense of parameter count, which is inappropriate for the deployment and practical applications. In this…

The NERCSLIP-USTC System for the L3DAS23 Challenge Task2: 3D Sound Event Localization and Detection (SELD)

ICASSP 2023accepted

Sound event localization and detection (SELD) aims at identifying the temporal activities of a known set of sound event classes and estimating their locations. It remains challenging especially when there are overlapped acoustic events. In this work, a robust network architecture with data augmentat…
