Web 2.0 Trust (W2Trust),
Trondheim, Norway
in conjunction with IFIPTM 2008

Web 2.0 has emerged as the adopted suite of technologies by
developers, users and business.  The new web 2.0 paradigm provides the
technology that enables government, businesses and users to interact
and integrate services and data and benefit The Wisdom of the Crowds.
Because of strong collaborative nature of Web 2.0 applications,
mechanisms for trust management are crucial for its healthy

Trust in Web 2.0 opens several new vistas for researchers and
practitioners. In particular, approaches to trust management designed
for Web 1.0 need to be revisited.  In Web 1.0 Trust was mostly related
to e-commerce and security of the portal.  The main trust issues were
related to the website content, and authenticity of the source which
posted data. With the advent of the Web 2.0 the issue of trust has
shifted from the people or companies that run a site to focus more on
the people that populate it. This new technology in fact enables users
to interact and collaborate seamlessly.  For example, using social
networks users are engaging with each other at a one to one level in
several ways, for business, pleasure, for knowledge sharing and so
forth.  The predominant issue is now whether one can trust the people
on a site, since the content is being generated by anyone and then
being rated by anyone.  How to ensure that what other users write is
true, authentic and will not misused is an open challenge.  Trust
evaluations are however fundamental to help users making the best
decisions when sharing resources and data.  Thus, the success of Web
2.0 strongly depends on the development of efficient, adequate and
scalable trust models.

During this one-day workshop attendees will discuss and analyze the
problems of trust in the Web 2.0 arena, and the potential consequences
in terms of privacy breaches and security vulnerabilities. The
dominant focus of the workshop will be on presentation of refereed
papers both long and short. We also plan on including a keynote and a
panel discussion.

We solicit papers, case studies, and participation from researchers,
systems architects, vendor engineers, and users. Suggested topics
include but are not limited to:

* Secure Mashup Technologies.
* Trust in Data Aggregation and Integration.
* Trust in Service Oriented Architecture.
* Security in Social Networks.
* Trust in New Technologies Such as AJAX.
