4 Local differential privacy for machine learning

This chapter covers

  • Local differential privacy (LDP)
  • Implementing the randomized response mechanism for LDP
  • LDP mechanisms for one-dimensional data frequency estimation
  • Implementing and experimenting with different LDP mechanisms for one-dimensional data

In the previous two chapters we discussed centralized differential privacy (DP), where there is a trusted data curator who collects data from individuals and applies different techniques to obtain differentially private statistics about the population. Then the curator publishes privacy-preserving statistics about this population. However, these techniques are unsuitable when individuals do not completely trust the data curator. Hence, various ...
