Data Redaction

Data Redaction is confused with data masking, neither it doesn’t work like SMD, but it works pretty much like DDM.

We know how data masking works i.e., it changes original data with random values so if data reaches into wrong hands, the identity of relevant person should not compromise.

Data Redaction also blacks out the data ON THE FLY which may or may not even make sense to the users using it.

There are four types of Data Redaction.

1. Random: Data is masked randomly
2. RedExp: Expressions are masked.
3. Partial: Some of the data is masked
4. Full: Everything is masked

We deal with Data Redaction on daily basis 😊. For example, when we do a Credit/ Debit Card transaction, a message comes on our mobiles. You must have noticed, except last few numbers all card numbers are always STARS i.e., ******* so for layperson those stars are Redacted values where partial data is masked.
