A successful transaction of digital contents is primarily dependent on security policies, trust relationships and benefit equilibriums among various participants in a DRM (Digital Rights Management)-enabling contents value chain ecosystem. We first analyzed basic value chain architectures in existence, together with some fundamental security and trust requirements. And then, a state-ofthe-art a...

When and why is the peace in a region so stable that the outbreak of a major war is unlikely or perhaps even inconceivable? There are essentially two ways to answer these questions; either a given system must possess necessary structural prerequisites of stability, or the social and cognitive conditions of stabil...

Disagreements between psychologists and economists about the need for and size of financial incentives continue to be hotly discussed. We examine the effects of financial incentives in a class of interactive decision-making situations, called centipede games, in which mutual trust is essential for cooperation. Invoking backward induction, the Nash equilibrium solution for these games is counter...

Trust prediction turns out to be an important challenge when cooperation among intelligent agents with an impression of trust in their mind, is investigated. In other words, predicting trust values for future time slots help partners to identify the probability of continuing a relationship. Another important case to be considered is the context of trust, i.e. the services and business commitmen...

Many business transactions on the Internet occur between strangers, that is, between entities with no prior relationship and no common security domain. Traditional security approaches based on identity or capabilities do not solve the problem of establishing trust between strangers.
