SXDOS.EXE and SXWIN.EXE are SOUNDEX calculators for the MSDOS and Windows (v3.1x, '95, '98, and NT 3.51 or later) operating systems.
The use of SOUNDEX codes provides an alternative to supplying surnames when confidentiality is required. Confidentiality is ensured as no SOUNDEX code is unique to a single surname. This makes it possible to share confidential data about (e.g.) sexually transmitted infections or psychiatric conditions without using surnames.
SOUNDEX coding is well suited to the public health surveillance of stigmatized diseases.

SOUNDEX coding may also be used to identify potential duplicate records with a high sensitivity. Combining SOUNDEX with other personal identifying data such as sex and year of birth provides a more specific method of identifying potential duplicates than the use of SOUNDEX alone.
