Identity and Trust on the Internet (IDtrust) Symposium 2011

IDtrust is devoted to research and deployment experience related to making good security decisions based on identity information, especially when public key cryptography is used and the human elements of usability are considered.

All software systems, from enterprise data centers to small businesses and consumer-facing applications, must make access control decisions for protected data. IDtrust is a venue for the discussion of the complete access control process (authentication, authorization, provisioning and security decision workflow), addressing questions such as: "What are the authorization strategies that will succeed in the next decade?" "What technologies exist to address complex requirements today?" "What research is academia and industry pursuing to solve the problems likely to show up in the next few years?"
