The 26th ACM Symposium on Applied Computing
at TaiChung, Taiwan

Track: Trust, Reputation, Evidence and other Collaboration Know-how (TRECK)

Proceedings: ACM printed form, ACM CD-ROM and ACM digital library, possible follow-up Journal issue, e.g., was Applied Computing Review in 2010

Aims and scope of the TRECK track:

Computational models of trust and online reputation mechanisms have
been gaining momentum. The ACM SAC 2005, 2006, 2007, 2008, 2009 and
2010 TRECK tracks attracted researchers from both academia and
industry who have joined an online group at

The goal of the ACM SAC 2011 TRECK track remains to review the set of
applications that benefit from the use of computational trust and
online reputation. Computational trust has been used in reputation
systems, risk management, collaborative filtering, social/business
networking services, dynamic coalitions, virtual organisations and
even combined with trusted computing hardware modules. The TRECK track
covers all computational trust/reputation applications, especially
those used in real-world applications.

The topics of interest include, but are not limited to:
Trust management, reputation management and identity management
Pervasive computational trust and use of context-awareness
Mobile trust, context-aware trust
Web 2.0 reputation and trust
Trust-based collaborative applications
Automated collaboration and trust negotiation
Trade-off between privacy and trust
Trust/risk-based security frameworks
Combined computational trust and trusted computing
Tangible guarantees given by formal models of trust and risk
Trust metrics assessment and threat analysis
Trust in peer-to-peer and open source systems
Technical trust evaluation and certification
Impacts of social networks on computational trust
Evidence gathering and management
Real-world applications, running prototypes and advanced simulations
Applicability in large-scale, open and decentralised environments
Legal and economic aspects related to the use of trust and reputation engines
User-studies and user interfaces of computational trust and online
 reputation applications

Submission guidelines are posted on the TRECK 2011 Web site (, which always contains the latest updates.

Authors are invited to submit full papers about original and
unpublished research. A paper cannot be submitted to more than one
track. We would like to encourage the submission of industrial
experience reports and reports of innovative applications.

The body of each paper should not exceed 6,000 words. The standard
paper is 6 ACM pages long and 2 extra ACM pages may be added.

Submissions should be properly anonymized to facilitate blind
reviewing.  At least three reviewers will be assigned to each
submission to the TRECK track.
