Abstract: | We show that the {\em privacy hierarchy} for $N$-argument functions $f(x_{1},...,x_{N})$ which are defined over finite domains, has exactly $\lceil \frac{N}{2} \rceil$ levels. We prove this by constructing, for any $\lceil \frac{N}{2} \rceil \leq t \leq N -2$, an $N$-argument function which is $t$-private but not $t + 1$-private. |
