Knowing about trust between members of an online social network (OSN) is essential for many applications. In this paper we propose and discuss methods for deriving information about trust within a social network by analyzing disclosure of personal information items. A formal model of trust and disclosure is presented and possible trust functions were analysed. We distinguish different types of information and assess their privacy value. A methodology for calculating privacy values and trust functions is provided.
