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
