Cache Me If You Can: Accuracy-Aware Inference Engine for Differentially Private Data Exploration. (arXiv:2211.15732v1 [cs.CR])

Differential privacy (DP) allows data analysts to query databases that
contain users' sensitive information while providing a quantifiable privacy
guarantee to users. Recent interactive DP systems such as APEx provide accuracy
guarantees over the query responses, but fail to support a large number of
queries with a limited total privacy budget, as they process incoming queries
independently from past queries. We present an interactive, accuracy-aware DP
query engine, CacheDP, which utilizes a differentially private cache of past
responses, to answer …
