Period-conscious Time-series Reconstruction under Local Differential Privacy
Yaxuan Wang, Tianxin Li, Enji Liang +2
Periodic patterns are fundamental cues in multimedia signals and systems, including repetitive motion in video (e.g., gait cycles), rhythmic and pitch-related structure in audio, a…
Private Speech Classification without Collapse: Stabilized DP Training and Offline Distillation
Yadi Wen, Tianxin Li, Enji Liang +2
We study example-level private supervised speech classification under a practical release constraint: training may access privileged side information, but the released model must b…
Dual Utilization of Perturbation for Stream Data Publication under Local Differential Privacy
Rong Du, Qingqing Ye, Yaxin Xiao +3
Stream data from real-time distributed systems such as IoT, tele-health, and crowdsourcing has become an important data source. However, the collection and analysis of user-generat…
Privacy for Free: Leveraging Local Differential Privacy Perturbed Data from Multiple Services
Rong Du, Qingqing Ye, Yue Fu +1
Local Differential Privacy (LDP) has emerged as a widely adopted privacy-preserving technique in modern data analytics, enabling users to share statistical insights while maintaini…
Interactive Trimming against Evasive Online Data Manipulation Attacks: A Game-Theoretic Approach
Yue Fu, Qingqing Ye, Rong Du +1
With the exponential growth of data and its crucial impact on our lives and decision-making, the integrity of data has become a significant concern. Malicious data poisoning attack…
Differential Aggregation against General Colluding Attackers
Rong Du, Qingqing Ye, Yue Fu +4
Local Differential Privacy (LDP) is now widely adopted in large-scale systems to collect and analyze sensitive data while preserving users' privacy. However, almost all LDP protoco…
Matrix Bloom Filter: An Efficient Probabilistic Data Structure for 2-tuple Batch Lookup
Yue Fu, Rong Du, Haibo Hu +2
With the growing scale of big data, probabilistic structures receive increasing popularity for efficient approximate storage and query processing. For example, Bloom filters (BF) c…
Meta-Key: A Secure Data-Sharing Protocol under Blockchain-Based Decentralised Storage Architecture
Dagang Li, Rong Du, Man Ho Au +1
In this letter we propose Meta-key, a data-sharing mechanism that enables users share their encrypted data under a blockchain-based decentralized storage architecture. All the data…
Introduction of Improved Repairing Locality into Secret Sharing Schemes with Perfect Security
Yue Fu, Shuhao Sun, Dagang Li +1
Repairing locality is an appreciated feature for distributed storage, in which a damaged or lost data share can be repaired by accessing a subset of other shares much smaller than…
