DP query analysis

Write an ordinary aggregation query; anon.dp_query derives the sensitivity, adds Laplace or Gaussian noise, and refuses what it can't bound.

Table

Aggregate

WHERE filter (optional)Query sent to dp_query

Mechanism

ε: 1.00

Trials: 30

Estimated sensitivity Δ

Δ = 1row-level

no DP PID: the neighbor is add/remove one row, so Δ = base

Laplace scale b = Δ/ε = 1.00
