Database emerged as a big and important field in software development nowadays and use of database is increasing day by day.The use of database is increasing with the passage of time and the security & privacy issues of data in the database are also increasing so different techniques are emerging to tackle these issues .Data masking is the process of de-identifying (masking) specific data elements within data stores.The main reason for applying masking to a data field is to protect data that is classified as personal identifiable data, personal sensitive data or commercially sensitive data, however the data must remain u sable.There are variety of situations in which users, developers or other personnel may not be allowed to view information that they are not authorized to see such as in development phase, training sessions, testing etc.Many methods are used for data masking such as substitution, shuffling, variance, encryption, nulling out, field masking etc.Data masking is a technique used to hide the original data from developers and end users in development process and t raining sessions.
