Balancing Privacy-Utility of Differential Privacy Mechanism: A Collaborative Perspective

Algorithm 1

Collaborative algorithm of differential privacy mechanism.

	Input: Data utility , desired privacy budget , -sensitivity
	Output:
(1)	Computing the utility factor from data utility ;
(2)	while required privacy budget do
(3)	Generating noise using differential privacy mechanism with desired privacy budget ;
(4)	end while
(5)	whiledo
(6)	and ;
(7)	end while
(8)	Computing noise
(9)	Adding noise to numerical query results ;
