The Korean Social Security Number (KSSN) is similar to the United States Social Security Number (US SSN) in that it is used to identify a citizen in Korea. It contains 13 digits, and is in the following format:<\/span><\/p>\n

BBBBBB-GRRRRSC<\/pre>\n
The first six characters of the KSSN comprise the recipient\u2019s date of birth, while the seventh digit specifies gender. The next four numbers signify the region where the person was born. The 12th digit is a serial number based on the region and date of birth. The final character is a calculated check character used to validate the KSSN.<\/p>\n
IRI has created new functions for its RowGen<\/a>\u00a0test data generation software product for those who wish to create valid or invalid KSSN values, and\/or validate existing KSSN values. \u00a0Any number of records can be generated and sent to one or more output file or table targets in one or more (custom) formats, with or without other data fields. The other fields can either be randomly generated, or randomly selected from real data, to provide realism and privacy together.<\/p>\n

\nCreating Valid KSSN Values<\/strong><\/p>\n
To create a computationally and structurally correct KSSN, the RowGen user can define a job script similar to this one:<\/p>\n
\/INFILE=RowGen_KSSN_valid.placeholder.in\r\n   \/ALIAS=RGKSSN\r\n   \/PROCESS=RANDOM\r\n   \/INCOLLECT=1   # Number of records to produce\r\n   \/FIELD=(NATID=natid_gen_korea(\"64\/12\/26\", \"M\"), TYPE=ASCII, POSITION=1,\r\n   SEPARATOR=\"\\n\")\r\n\/REPORT\r\n\/OUTFILE=stdout\r\n   \/PROCESS=RECORD\r\n   \/FIELD=(NATID, TYPE=ASCII, POSITION=1, SEPARATOR=\"\\t\")<\/pre>\n
The output from this routine is:<\/p>\n
641226-3191835<\/p>\n
