Abstract
Systems, methods, and other embodiments associated with virtual masked databases are described. One example system includes a masking logic to mask an unmasked column of a database table to produce a masked column. The masked column is then added to the database creating a bi-masked database. A portion of the bi-masked database is then selected by a view logic and provided to a user. The view provided to the user may allow fast, conflict free queries and updates to the database. By providing the user either masked or unmasked data based on information associated with the user, an added layer of data security may be achieved.
