A Secure Truth Discovery for Data Aggregation in Mobile Crowd Sensing

Algorithm 1

Truth discovery process.
Input: Sensing Data for n participants:
output: Estimation Truth for m objects:
(1) Randomly initialize the ground truth for each object;
(2)repeat
(3)  for i = 1, 2, …, n do
(4)   for j = 1, 2, …., m do
(5)    Weight Update base on equation (2);
(6)    Truth Estimate base on equation (5);
(7)   end for
(8)  end for
(9)until Convergence criterion is satisfied;
(10)return;
