Call for Papers
ACM CCS2007 Workshop on Digital Identity Management
November 2, 2007, George Mason University, Fairfax, VA, USA

"Usability Issues for Identity Management"

As the Web 2.0 trend exemplifies, user experiences on the Net are becoming more and more interactive, dynamic, and personalized. With appropriate control over the number and use of their identity(s), users can enjoy the advantages of highly sophisticated personal services without the management burden they currently face or sacrificing their privacy. However, standing in the way of this attractive goal are malicious identity-motivated attacks (such as phishing & pharming), inadequate user understanding of the underlying trust models (including the consequences of poorly set security and privacy preferences), and the complexity of managing how identities are to be used, shared, and delegated. To address such issues, many technological solutions have been already proposed, both in the industry and academia, to date with mixed success.

To ensure that the emerging identity management technologies are accepted by end-users, we must reconcile (or strike the right balance between) two goals that are generally thought to be contradictory: the usability of the systems on one hand and their security and privacy on the other. The aim of this workshop is to gather vendors, users, and researchers, in the areas of identity management, to discuss and provide recommendations for the best approaches for making implementable and deployable improvements to the usability of identity management. Topics of particular interest include (but are not limited to):

• User interaction design for identity management
• Social identity
• User centric identity
• Expressing trustworthiness of identity management to users
• Empirical analysis of usability problems with identity management systems
• Evaluation methodologies for usability of identity management systems
• Novel user interface technologies for identity management
• Privacy enhanced user interaction
• User education on identity management
• Elicitation of privacy preferences from end users
• Identity theft prevention
• User-readable privacy policies
• Methodologies and interfaces for managing multiple identities including delegation
• Identity theft prevention
• Privacy-enhancing identity management
• Consistent UI for identity transactions

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 the 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 June 8, 2007. Submission instructions will be announced shortly. Authors of accepted papers must guarantee that their paper will be presented at the workshop.
