Data Masking Techniques

Substitution

Organizations substitute the original data with random data from supplied or custom lookup file. This is an efficient and effective way to disguise data since businesses preserve the data’s integrity and structural format.

Shuffling

In shuffling, organizations substitute the original data with another authentic-looking data, but the same column’s entities are shuffled. The value can move vertically or randomly along the columns.

Blurring

The value stored in the database is altered with a defined range of values available.

Character Scrambling

Characters are randomly scrambled, rearranging the order of the characters involved. This process is irreversible, so the original data cannot be obtained from the scrambled data.

Tokenization

Tokenization is a reversible process where the data is substituted with random placeholder values. Tokenization can be implemented with a vault or without, depending on the use case and the cost involved.
