Advanced SIM Capabilities Supporting Trust-Based Applications

摘要

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 paper assess how this new capabilities together with the pervasiveness and security of the SIM card can support the development and design of trust-based applications. 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.
