                     Call for Papers

   The Fourth ACM Workshop on Digital Identity Management
               (Collocated with ACM CCS2008)

October 31, 2008, George Mason University, Fairfax, VA, USA

                "Services and Identity"

As the competitive edge of the global economy is shifting to 
"services" delivered over the Internet, we need a way of making 
identity available on-demand to the services in an open, scalable, 
and secure manner.  Identity for services is a holistic concern 
that must satisfy technology, regulatory and business needs for 
existing and emerging markets, such as Software as a Service (SaaS) 
and Service Oriented Architectures (SOA).  Identity services should 
introduce consistency, efficiency and scalability in IT infrastructures 
built on the Internet to form the new "identity layer".  Also, it 
should be easy for developers to incorporate identity services as part 
of distributed application logic.
To fully achieve the potential benefits of identity managed as a set 
of services, such as cost-effectiveness and shorter deployment times, 
several security and privacy challenges must be addressed. Such 
challenges arise because of the complex and distributed systems across 
different organizations involved in identity service offerings. The goal 
of the workshop is to lay the foundation and agenda for further research 
and development in this area. Under the broad umbrella of "Services and 
Identity", we encourage both researchers and practitioners to participate 
and submit papers on topics including, but not limited to the following:

Identity management for SaaS
SOA for identity
Scalability issues in identity management
Resilient identity service provisioning
Dynamic mutual trust negotiation
SLA for identity services
Identity based access control
Migration to identity services
Identity service discovery
Virtual directories
Identity management process assurance
Identity life-cycle
Externalization of identity
Risk management for identity
Identity oracles
Translation and resolution of namespaces
Network transport as a service
Privacy and hosted services
Mobile identities
Balance between de-centralization of identity and centralization of controls
Privacy preservation during orchestration of services in multiple domains

Submission Instructions: 
Submitted papers must not substantially overlap with papers that have 
been published or that are simultaneously submitted to a journal or a 
conference with proceedings. Papers should be at most 10 pages, using 
at least 10.5-point font and reasonable margins on A4 or US letter-size 
paper (8.5 inch x 11 inch). Committee members are not required to read 
the appendices, and so submissions should be intelligible without them. 
Each submission should start with the title, abstract, and names and 
contact information of authors. The introduction should give background 
and summarize the contributions of the paper at a level appropriate for 
a non-specialist reader. Papers must be electronically submitted in PDF 
or portable PostScript format and must be received by the deadline of 
May 23, 2008. The instruction for the submission will be noticed shortly. 
Authors of accepted papers must guarantee that their paper will be 
presented at the workshop.
