The SF Chronicle reports that airline res systems use an ancient name
indexing system that guarantees masses of false positives.
Story here.
Also fun to note that even the TSA is critical of the current system. Too bad that their solution is the bizarre and invasive CAPPS II system, a beta software so offensive it has led to a boycott of Delta Airlines.
Many airlines rely on name-searching software derived from "Soundex," a
120- year-old indexing system first used in the 1880 U.S. census. It was
designed to help census clerks quickly index and retrieve sound-alike
surnames with different spellings -- like "Rogers" and "Rodgers" or
"Somers" and "Summers" -- that would be scattered in an alphabetical list.
Soundex gives each name a key using its first letter and dropping the
vowels and giving number codes to similar-sounding vowels (like "S" and
"C"). The system gives the same code, L350, for "Laden" and all
similar-sounding names: Lydon, Lawton, and Leedham."
Soundex is well known these days to genealogical hobbyists. Here is an
article laying out the Soundex coding scheme.
And here is a Web-based Soundex calculator to see what your last name will get you into. I entered Moussaoui and found that it gets lumped in with forty other fairly common last names, which might spell trouble for designer Bob Mackey and ficitious trucker BJ McKay (no word as of yet on whether or not his best friend Bear is implicated in the investigation.)
