John,

This begs the question - where are you going to store the unique string so when (if) the user comes back you can match the entered string?

If you're using some type of flat file store, or in-memory storage - all the above should work fine. However, if your using a database, most rdbms all ready have this capability built in. Sybase has identity columns and Oracle has sequences (Mysql has ??) these are guarenteed (sp?) to be unique and can be most useful for your situtation.
