Microsoft is leading the move to claims-based access with an announcement 
  this week of a claims-aware application codenamed "Geneva" Framework.
According to a Tuesday 
  post on the Geneva Team Blog , the Geneva Framework is the successor to 
  a previous beta known as Zermatt. Both are part of a suite of secure access 
  products known as "Geneva," which was rolled 
  out in October at Microsoft's Professional Developers Conference.
Geneva, according to MSDN, simplifies user access to applications and services 
  using claims-based access instead of the legacy identification-based access 
  prevalent today in protected environments.
