An identity search algorithm for identifying a plurality of identity data such as personal names and entity names that might exist in a table or file containing a large number of identity data in an investigative environment. The algorithm is intended to identify person and entities in the shortest time possible with an overly inclusive results. The core algorithm is used in an environment with a growing number of names in the table, and implemented with a web-based user interface, it can dramatically improve identity-searching efficiency and increase the chance to generate useful leads in typical discovery and investigation.
