In some embodiments, the system integrates different unique identifiers from agencies and organizations and associated the different unique identifiers with each other in a table. In some embodiments, the table links all different unique identifiers to a single individual so that a search for any one identifier returns links to all records and data associated with the individual. In some embodiments, the system collects the different unique identifiers from organizations such as patient medical services, local and federal law enforcement databases, and private company records. In some embodiments, the system parses each component of each identifier and stores them as variations. In some embodiments, each parsed identifier is associated with a master identifier. In some embodiments, the system links the master identifier to all records and data across multiple organizations and agencies.
