Abstract

Nowadays, the growth of virtual environments such as virtual organizations, social networks, and ubiquitous computing, have led to the adoption of TRUSTconcept. One of the methods of making TRUST in such environments is to usea long-term relationship with a TRUSTed partner. The main problem of thiskind of TRUST, which is based on personal experiences, is its limited domain. Moreover, both parties of such TRUST relationship will face big problems ofcollecting data and forming reasonable and reliable beliefs. Considering theconcept of \group" in modeling TRUST is a way to overcome the above mentionedproblems. Since, GROUP-based TRUST is more suited with the nature of TRUST innew virtual environments. In this paper, a new TRUST model called \GTRUST" isproposed in which TRUST is considered as a collective and shared feature of allgroup members. Therefore, GROUP membership is used as the judgment criteriaregarding a person's expected behavior and how he can be a TRUSTee. GTRUSTis based on METAGRAPHs which are graphical data structures for representinga collection of directed set-to-set mappings. We show that by using GTRUST, large TRUST spaces between unknown individuals can be shaped e ectively. Theproposed model not only o ers a better description of human sense of TRUSTwhen considering communities, but also provides the setting for evaluating theTRUST of individuals whom we do not know, and therefore provides an extendedevaluation domain.
