Local differential privacy (LDP) can mask poisoning behavior in crowdsensing by making poisoned sensory data difficult to distinguish from benign sensory data, which in turn makes malicious workers difficult to identify and undermines reliable truth discovery. Conventional value based defenses lose discriminative power...

Repeated co-occurrences in worker trajectory data can expose latent relationships in mobile crowdsensing. Existing methods mainly focus on protecting individual or dyadic relationships, which inadequately capture higher-order relationships between trajectories. To address this problem, we propose a hypergraph-based def...

In federated learning (FL), client data often suffer from the challenges of data distribution imbalance such as Non-IID and noisy labels. Crucially, these two issues are highly coupled and mutually exacerbating: Non-IID data complicates the identification of noisy labels, while noisy labels severely amplify local model...
