The power curves of the Optimal Attack and QI Attack with different beacon setups with actual family members. For all attacks: (i) the first plot is when the beacon does not include any family members of the victim, (ii) the second plot is when only the mother of the victim is in the beacon, (iii) the third plot is when only the father of the victim is in the beacon and (iv) the fourth plot is when both parents of the victim are in the beacon. SNPs of the victim with MAF values smaller than t are hidden from the attacker
