Biometric identification is the standard for ensuring criminal information pertains to the correct individual. All states and the FBI use a form of biometric identification based on fingerprint images to uniquely identify a person. This ID may be referred to as the State Identification Number (SID) or FBI Number. Not all justice data systems capture this information. Much of the disposition data received from other data systems cannot be matched on the criminal history resulting in incomplete records. The data compiled in a criminal history is very accurate, but also often incomplete.
