Abstract
Current approaches for asserting trust focus on propagating known trust values amongst peers in a trusted network and do not provide measures for asserting a trust value from user interactions between peers. Moreover, Social Web applications assume that all users connected in one’s social graph share the same level of trust. These platforms do not provide any means to capture and differentiate trust levels amongst one’s connected peers. This makes it difficult for users to decide whom to trust and they have to rely on limited knowledge—their own or recommended by other peers. In this work, we present a trust framework for automatically asserting subjective trust values for connected users based on social user interactions—actions that provide users to interact with one another within a Social Network. In this work, we describe our model how we assert trust from these interactions. We also present our Trust Manager that automatically asserts user’s subjective trust values based on our model. These trust values help users to decide who is more trustworthy and with whom they can share their personal information.
