A service-based testbed for Trust Negotiation

Trust Negotiation allows users to develop trust incrementally, by disclosing credentials step by step. This way, services and resources can be shared in an open environment, and access rights can be granted on the basis of peer-to-peer trust relationships. This article presents a service-based testbed for Trust Negotiation. At its core, it is created as a generic framework based on the WS-Trust standard. It integrates a modular trust engine and a rule engine, which is used as a policy checker. The system is mainly oriented at Web services composition and location-based social networking scenarios

The Prospects for Consumer-Oriented Social Media

The term \u27social media\u27 refers to a cluster of applications and online services that support human interaction and content broadcasting and sharing. Current services are isolated islands or \u27walled gardens\u27, and are based on a business model that is highly exploitative of individuals and their data. An alternative, consumer-oriented approach is feasible, involving open architecture, inter-operability and portability features, fair terms and privacy-sensitivity. Key impediments to the emergence of such services are identified, and means of overcoming the impediments are outlined.
