http://infosecon.net/usec12/index.php USEC 2012 Workshop on Usable Security colocated with Financial Cryptography and Data Security 2012 March 2, 2012 Divi Flamingo Beach Resort Bonaire Submissions must be received at the site by November 16, 2011. Authors will be notified of acceptance by December 16th. A final version for the workshop should be received by January 16th. Many aspects of data security combine technical and human factors. If a highly secure system is unusable, users will move their data to less secure but more usable systems. Problems with usability are a major contributor to many high-profile security failures today. However, usable security is not well-aligned with traditional usability for three reasons. First, security is rarely the desired goal of the individual. In fact, security is usually orthogonal and often in opposition to the actual goal. Second, security information is about risk and threats. Such communication is most often unwelcome. Increasing unwelcome interaction is not a goal of usable design. Third, since individuals must trust their machines to implement their desired tasks, risk communication itself may undermine the value of the networked interaction. For the individual, discrete technical problems are all understood under the rubric of online security (e.g., privacy from third parties use of personally identifiable information, malware). A broader conception of both security and usability is therefore needed for usable security. The workshop on Usable Security invites submissions on all aspects of human factors and usability in the context of security. USEC'12 aims to bring together researchers already engaged in this interdisciplinary effort with other researchers in areas such as economics, intelligent interactions, artificial intelligence, theoretical computer science, and modeling. We encourage AI, HCI, security, psychologists, risk analysts, computer scientists, security specialists, business school faculty, and industry experts to submit original research. We particularly encourage collaborative research from authors in multiple fields.
