v0.2.3

  • Deprecated SmartNoise-Core
  • Please migrate to the OpenDP library: docs.opendp.org/

v0.2.2

  • Custom sensitivities may be passed directly to mechanisms
    • protect_sensitivity must be disabled in the privacy definition
  • Expand documentation for each component as well as Python Analysis class
  • Python Bindings: Analysis initializer only accepts keyword arguments.

v0.2.0

  • Bump minor version to reflect change in default behavior in v0.1.1

v0.1.2

  • Minor readme changes

v0.1.1

  • Python Bindings: enable protect_floating_point by default.
    • Real-valued queries are less susceptible to floating-point attacks, at the cost of utility
    • Use sn.Analysis(protect_floating_point=False) to enable the laplace and (analytic) gaussian mechanisms
  • Fix noise scaling issues in the Gaussian and Analytic Gaussian mechanism
  • Fixes for Gaussian and Analytic Gaussian accuracy
  • Postprocess geometric mechanism noise with clamping
  • Compute sensitivities as integers whenever possible (counts, histograms, sums)
  • Added runtime sanity checks to detect violations of static properties in pre-aggregated data
  • O(n^2) -> O(n) runtime performance in exponential mechanism and categorical imputation
  • Fixed an incorrect inference of dataset size when transforming a dataset with unknown size against a broadcastable scalar
  • Unions always permitted on public data
  • Added inference of nature (categories, bounds) to ToInt
  • Plug-in mean derives bounds for sum in laplace and geometric mechanism

v0.1

  • Renamed package to Smartnoise, version number reset
  • Added snapping mechanism
  • Added analytic gaussian mechanism
  • Added DP Linear Regression through the Theil-Sen transform and gumbel mechanism
  • Added generalized resize for privacy amplification by subsampling
  • Tightened c-stability checks to protect against adversarial dataset reordering when unioning data partitions
  • Modified error messages to contain suggested fixes
  • Bugfix to retain statistics when generating reports
