Law enforcement interoperability
Law enforcement, NIST making fingerprint files easier to search (GCN)
Not all AFIS are alike, however. State and local agencies often maintain their own databases, and although there can be some interoperability in a vertical hierarchy of local, state and federal databases, there is very little interoperability horizontally between neighboring jurisdictions. To search different databases, examiners must mark distinctive features for fingerprints manually for different systems, using different coding, notation methods and data definitions.
