Trusted secure service design: Enhancing trust with the future sim-cards
MetadataShow full item record
The SIM cards are going through several new enhancements both in the underlying hardware and its capabilities. They are becoming secure wireless networked devices containing embedded sensors. This thesis assess how this new SIM capabilities together with its pervasiveness and security can support the development and design of trust-based applications. It reviews the new trust possibilities based on the identity factor, connectivity and context-awareness sensors on the SIM. Moreover, we present a specific use-case around a seamless trust builder for social networks, which makes use of sensed inputs towards building hard contextual evidences to trust relations. We conclude with the description of the challenges of building this evidence based trust-builder and the necessary steps to going from the prototype we developed to a real application which may accurately describe trust relations.
