Abstract：As a new media, social network gains a wide range of social influence, and the social network based e-commerce becomes more and more popular, which make the study of information propagation of great significance. A trust based information propagation model was presented in this paper according to the trust relationship between people in daily life. First, the algorithm of data mining was employed on personal information to make the classification of the users. And then the value of trust between the users was calculated according to their relationships. At last, this paper predicted the range of information propagation by using the trust value between the users and messages. Compared with two basic methods, the final experiment shows that the results generated by the model are enhanced by 15% in precision, while the time used decreases more than 50%. The results differ with the statistic results on the dataset at 5%, which shows that the model preforms well in practice.
