Deriving cryptographic keys from biometric parameters

A device, comprising:

• a biometric parameter detector operative to obtain at least one biometric parameter from a user;
• a storage device;
• and
• a processing circuit operative to
• obtain biometric parameters from the user using the biometric parameter detector;
• compare the biometric parameters to a database of biometric data objects stored in the storage device to identify biometric data objects that most closely match the biometric parameters from the user, wherein the database includes at least one authentic biometric data object for the user and a larger number of synthetic biometric data objects not associated with the user;
• obtain a plurality of candidate cryptographic keys based on the biometric data objects that most closely match the biometric parameters from the user;
• and
• apply one or more of the plurality of candidate cryptographic keys in an attempt to access information secured with a valid cryptographic key of the user.

A machine-readable storage medium for biometric processing, the machine-readable storage medium having one or more instructions which when executed by at least one processing circuit causes the at least one processing circuit to:

• obtain biometric parameters from the user;
• compare the biometric parameters to a database of biometric data objects to identify biometric data objects that most closely match the biometric parameters from the user, wherein the database includes at least one authentic biometric data object for the user and a larger number of synthetic biometric data objects not associated with the user;
• obtain a plurality of candidate cryptographic keys based on the biometric data objects that most closely match the biometric parameters from the user;
• and
• apply one or more of the plurality of candidate cryptographic keys in an attempt to access information secured with a valid cryptographic key of the user.
