This paper explores analytical connections between the perturbation
methodology of the Australian Bureau of Statistics (ABS) and the differential
privacy (DP) framework. We consider a single static counting query function and
find the analytical form of the perturbation distribution with symmetric
support for the ABS perturbation methodology. We then analytically measure the
DP parameters, namely the $(\varepsilon, \delta)$ pair, for the ABS
perturbation methodology under this setting. The results and insights obtained
about the behaviour of $(\varepsilon, \delta)$ with respect …
