The Social Security Administration (SSA) puts thousands of Americans at risk of identity theft each year by accidentally leaking their Social Security Numbers, names and dates of birth, according to an investigative report by the Scripps Howard New Service .
The leaks are the result of keying errors made by SSA employees when entering data into the agency's Death Master File, a database containing the records of 90 million deceased Americans.
Since 1980, when the SSA first started making the file publicly available, more than 400,000 SSNs belonging to living Americans may have been inadvertently published in the Death Master File as a result of the errors, according to the report.
In most cases, the victims of the inadvertent leaks are not informed of the breach. Many discover the error only after they ran into problems such as having their bank accounts frozen, job interviews refused or having their credit, mortgage or student loan applications declined, Scripps Howard reported.
The SSA did not immediately respond to a Computerworld request for comment.
For its report, Scripps Howard reviewed three files from the Death Master File and discovered 31,931 living Americans listed erroneously in them. Dozens of those who were incorrectly listed were later contacted by the news service. None said they'd been informed of the breach by the SSA.
The SSA has admitted that it inadvertently lists about 14,000 living people in the Death Master File each year, Scripps Howard said. Using that estimate, more than 400,000 records have been released since 1980, the report noted. (See also "Researchers Expose Security Flaw in Social Security Numbers.")
In the report, Scripps Howard quotes SSA Commissioner Michael Astrue, who spoke to members of Congress about the issue last month. Astrue said that the SSA takes prompt action to correct any errors it discovers. Any breach involving the accidental leakage of SSNs is also promptly reported to the U.S. Computer Emergency Response Team.
Astrue said the SSA has so far found no instance of fraud or misuse as a result of the inadvertent exposure.
