Abstract
A biometrically enabled machine readable token is biometrically associated with the user or owner of the token. Such a token may be generated by initially providing biometric data of the user, and concealing the biometric data such that the biometric data is selectively accessible. The concealed biometric data is then used in generation of a token request message either by embedding the concealed biometric data into the token request message or by providing a concealed link thereto within the token request message. Once a token request message is received by a token issuer the concealed biometric data may be associated with the token. As the biometric data is concealed the specifics of that data are not accessible to third parties. Optionally the authenticity of the token may be effected by having the token issuer digitally signing the token.
