Abstract: Trust is a concept taken from social sciences and is
considered as a soft security approach that is effective in
reducing risk. In this paper, for estimating the trust between
unknown nodes, a group-based trust propagation method has
been proposed. Most of the conventional trust propagation
methods are not applicable for trust evaluation of today\\'s large
trust graphs. Our trust propagation method is scalable because
of using grouping method. For better trust estimation inside
group the confidence of trust value have been considered. We
also consider two factors Intermediate Group Confidence
(IGC) and Group Confidence (GC) for confidence of trust
between two groups. To evaluate this method a real large data
set of advogato.org is used. Evaluation of accuracy is based on
correlation and mean absolute error(MAE). Comparing the
proposed method with the Iterative Multiplication method
(IMS) results suggests that the correlation and absolute mean
error have been improved. In addition, due to the use of groupbased
method the speed of the proposed method has been
improved.
