Data Redaction is confused with data masking. Its kind of true and false at the same time. It doesn’t work like Static Data Masking (SMD) but it works like Dynamic Data Masking (DDM).
Let’s decode it…..
We know how data masking works i.e., it changes data with random values, means to hide original data so if data reached into wrong hands, one should not be able to identify the individual to whom the record refers.
Data Redaction totally black 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 layman those stars are Redacted value where partial data is masked.

2 年Data Radiation is a subclass of Data Masking: I am amazed I know this information since I am using a credit card, but I do not see the term and subclassification like data radiation--> Expression are masked.
