Table 3:

Privacy (in terms of estimation error) and utility (in terms of accuracy of beacon responses) of the proposed scheme for different values of $\widehat{\tau }$ (correlation threshold) when $\widehat{\gamma }=0.03$.and ϵ = 1. Estimation error is computed by assuming the attacker uses τ = 0.02 and γ = 0.03.

$\widehat{\tau }$	0.02	0.04	0.06	0.08	0.1
Estimation Error (E)	0.483	0.486	0.492	0.499	0.503
Accuracy (A)	0.950	0.942	0.918	0.892	0.865
