Social Security Number redux

This article describes the continuing problem of banks using social security numbers as identifiers and partial passwords.  It seems the FTC has previously identified the problem of SSNs being utilized as authentication tokens and has even gone so far as to propose legislation to reduce the over-reliance on them in industry.  I would like to point out my simple solution doesn’t require any legislation, simply publish SSNs on the internet as a ubiquitous identifier, thereby reducing their value to identity thieves and as authentication tokens.
