US Patent 7421398 System and method for implementing healthcare fraud countermeasures

A method of discouraging healthcare fraud in conjunction with providing a health care service to a patient in which the patient provides a biometric signature. An event record is created where the event record creates an association between the biometric signature, a patient identifier, and location information indicating a location at which the biometric signature is obtained. The event record is stored in a central data store and can be later retrieved to verify the patient was present at the location.
