A class that implements the basic Laplace mechanism of differential privacy, for privatizing numeric vector releases.
# S4 method for DPMechLaplace
show(object)
an instance of class DPMech
.
show
: automatically prints the object.
sensitivity
non-negative scalar numeric L1 target sensitivity.
Defaults to Inf
for use with sensitivitySampler()
.
target
the target non-private function to be privatized, takes lists.
Defaults to a constant function. Laplace mechanism assumes functions that
release numeric vectors of fixed dimension dims
.
gammaSensitivity
NA_real_
if inactive, or scalar in [0,1)
indicating that responses must be RDP with specific confidence.
dims
positive scalar numeric dimension of responses. Defaults to
NA_integer_
for use with sensitivitySampler()
which can
probe target
to determine dimension.
