1. A system for data and user authentication using biometric means, to verify to a third party that a document purporting to be from a first party is an unaltered version of a document issued by said first party, the system comprising: a) at least one network enabled client device for sending data to a network; b) at least one biometric data input mechanism on said client device for capturing biometric data, said data input mechanism further being configured to digitally bind said captured biometric data at said client device to a document, said digital binding comprising encrypting said document using a session key generated from said biometric data, said session key being retained for subsequent decryption of said document therefrom at an instigation of said third party; and c) an authentication server configured with storage for storing said session key, said storage making said session key available for said instigation by said third party, and enabling remote data and user authentication at said authentication server side and further configured to pass a token to said client device if said user authentication is successful, said token to enable generation of said binding in association with said authentication, said binding thereby verifying the document in a current version as coming from said first party, and reversing said binding using said session key thereby verifying to said third party that a document obtained thereby is said current version from said first party, said first party identification thereby comprising biometric identification.
