The definition of privacy determines parameters for sensitivity derivations and the set of available algorithms.

Fields

group_size: u32

Privacy leakage with respect group_size number of rows. This is typically one.

neighboring: i32

Define the kind of perturbation that may be applied to a dataset to create a neighboring dataset.

strict_parameter_checks: bool

enable to reject the use of algorithms using delta when n is not known enable to reject the use of algorithms when some soft violations of assumptions are observed

• epsilon greater than one with the gaussian mechanism

protect_overflow: bool

enable for tighter bounds checking to prevent leaks via overflow/underflow

protect_elapsed_time: bool

enable if side-channel elapsed execution time is considered part of the release

protect_memory_utilization: bool

enable if side-channel memory usage is considered part of the release

protect_floating_point: bool

enable to block mechanisms known to be vulnerable to floating point attacks

protect_sensitivity: bool

enable to prevent manual insertion of sensitivity to mechanisms

Implementations

impl PrivacyDefinition

pub fn neighboring(&self) -> Neighboring

Returns the enum value of neighboring, or the default if the field is set to an invalid enum value.

pub fn set_neighboring(&mut self, value: Neighboring)

Sets neighboring to the provided enum value.
