Mobile Data Collection and Analysis with Local Differential Privacy

2019

Local Differential Privacy (LDP), where each user perturbs her data locally before sending to an untrusted party, is a new and promising privacy-preserving model for mobile data collection and analysis. LDP has been deployed in …

Estimating Numerical Distributions under Local Differential Privacy

2019 · arXiv (Cornell University)

When collecting information, local differential privacy (LDP) relieves the concern of privacy leakage from users' perspective, as user's private information is randomized before sent to the aggregator. We study the problem of recovering the distribution …
