Even after committing the delete of a row in a table, the 'ghost' data remains on the datafile.
The 'ghost' data could potentially be accessed by a malicious user, circumventing the database access controls, using a hex editor on the datafile.
Short of moving the table (and all other segments) into a new tablespace and then shredding the old datafile, how can I securely delete a specific row?
