Commonly Used Data Masking Techniques - TDM

In my previous posts I discussed about Data Subset and Data Masking.  In this post, I will discuss the data Masking techniques that are widely used.  This is by no means exhaustive but will provide a general idea of the techniques that are available.

  • Random Substitution
    • In this technique, the value to be masked is replaced or substituted with a random value.  Depending on the nature of the random value, they can be further categorized into
      • Random Numbers
      • Random Dates
      • Random Seed Values For ex.
        • Names
        • Addresses
        • SSN Numbers
        • Credit Card Numbers
        • Telephone numbers
        • And a lot more
      • Random Alphanumerics
