The U.S. Government's Soundex technology, an obsolete algorithm that was used in World War I to match names, is the foundation of the database technology used by the FBI National Crime Information Center (NCIC) and other watch list databases. However, says Mark Tanner of the FBI, NCIC's name-matching is not as powerful as some other tools available, even though Soundex is what's available to police officers in patrol cars.' Zalmai Azmi, CIO of the FBI, says officials are considering replacing Soundex at NCIC. Two other terrorist watch lists using Soundex are the National Automated Immigration Lookout System II (NAILS II) and the Interagency Border Inspection System (IBIS), which are used by Department of Homeland Security (DHS). NAILS II has millions of files, approximately 58,000 of which concern suspected or known terrorists and their supporters. IBIS is better than NAILS II according to a report from the Congressional Research Service, but it is not regarded as equal in power to the State Department's Consular Lookout and Support System (CLASS), especially for certain search functions. More advanced technologies will replace Soundex, says Steve Cooper, CIO of Homeland Security, to help avoid possibly inaccurate name matching. Soundex has been shown to make mistakes, especially with foreign names, since Soundex systems do not capture the punctuation of names in non-Roman alphabets and sometimes cannot track alternate spellings of a name.
