GNS: Forge High Anonymity Graph by Nonlinear Scaling Spectrum

Algorithm 1

Design the scaling function

	Input: The diagonal matrix composed of eigenvalues of matrix M
	Output: The suitable scaling function for the
(1)	Calculate the distribution of
(2)	ifthen
(3)	do choose a nonlinear and monotonic increasing function in this distribution
(4)	else ifthen
(5)	do choose a nonlinear function that decreases in the range less than 0 and increases in the range bigger than 0
(6)	while the scaled result of f (x) is not similar to the original spectrum then
(7)	do adjust the parameters for
(8)	Return
