Introduction to MAGNATE: Gathering and analysis of trust evidence

Trust is often calculated based on evidence which may come from a set of diverse sources. Challenges in trust calculation include the lack of a standard way to access evidence sources, lack of a standard for presenting evidence, unreliable evidence sources and differences of opinion on how evidence should be interpreted. This work shows that there are aspects of trust calculation that can be abstracted into a middleware. Doing so makes it easier for developers to develop applications that take trust into account when making decisions.
