• The goal is to provide a privacy preserving methodology for strong biometric authentication in federated identity management systems. • Privacy Preserving Multifactor Authentication [1]: multifactor authentication is essential for secure authentication mechanisms. The identity management framework is used to provide proofs of multiple strong identifiers for a given user. • Interoperability: Our scheme provides an interoperable, usable, secure, and inexpensive to use biometric authentication in a federation. • User Control : The raw biometric never leaves the client machine therefore providing complete control to its owner.
