What is Data Hiding?
Data hiding is a protection mechanism. Data hiding is the simple concept of hiding data in a place where it is not easily discovered. This concept is extensively used in security controls and in programming.
An example of data hiding in an organization is the use of classification labels. A database can be classified as Top Secret, which will “hide” (restrict) the database from lower classification levels. Someone who has a Secret clearance won’t be able to read the Top Secret database.
