How can we use data masking transformation in Informatica?
Use the Data Masking transformation to change sensitive production data to realistic test data for non-production environments. The Data Masking transformation modifies source data based on masking rules that you configure for each column. Create masked data for software development, testing, training, and data mining.
What is data masking with example?
Deterministic data masking involves replacing column data with the same value. For example, if there is a first name column in your databases that consists of multiple tables, there could be many tables with the first name.
What is the default masking type for data masking transformation in Informatica?
Random Masking The Data Masking transformation returns different values when the same source value occurs in different rows. You can define masking rules that affect the format of data that the Data Masking transformation returns. In random masking, numeric, string, and date values can be masked.
What is the need to mask data?
Data masking is a way to create a fake, but a realistic version of your organizational data. The goal is to protect sensitive data, while providing a functional alternative when real data is not needed—for example, in user training, sales demos, or software testing.
What is key masking?
A column configured for key masking returns deterministic masked data each time the source value and seed value are the same. The Data Masking transformation returns unique values for the column.
What is data masking in SQL?
Data Masking is the process of hiding data with different rules. One of the main reasons to apply data masking is to protect Personal Identifiable Information (PII) and sensitive data from unauthorized access. Even when unauthorized users access these data, they will not be able to view the actual values.
What is purpose of Data Masking?
How do you unmask data in SQL?
Users with SELECT permission on a table can view the table data. Columns that are defined as masked, will display the masked data. Grant the UNMASK permission to a user to enable them to retrieve unmasked data from the columns for which masking is defined.
How do I mask a column in SQL?
To mask a column, use the SQL syntax MASKED [AS {BASIC | NULL | 0 | ‘ ‘}] as a column attribute on the CREATE TABLE, CREATE TABLE AS SELECT, or ALTER TABLE ALTER COLUMN statement. The MASKED attribute marks the column as being a protected resource.
What is masking in SQL?
Dynamic Data Masking in SQL Server is a masking technique that can be used to hide data. This feature is available in SQL Server as well as in SQL Azure. There are four types of masking and UNMASK permission should be provided to the users in order to view the data.
How do you mask data in SQL?
If you want to hide the data, then you can grant DENY permissions for the relevant column for the user. However, there are no special permissions needed to create masked columns. You only need the CREATE TABLE permissions and ALTER column permission to create or alter mask column.
How do I mask a string in SQL?
Use a combination of STUFF , REPLICATE and CHARINDEX . CHARINDEX will give you the position of a particular string inside another one (the first by default). REPLICATE will repeat a string N amount of times, we use this for the mask.
How do I mask data in a column?
To specify a mask for a particular column, you have to use the “MASKED WITH” clause. Inside the MASKED WITH clause, you have to specify the FUNCTION that you want to use for masking. If you want to perform default masking, you use the “default()” function.
Can data masking be reversed?
Encryption, tokenization, and data masking work in different ways. Encryption and tokenization are reversible in that the original values can be derived from the obfuscated data. Data masking, on the other hand, is irreversible if done correctly.
What is data masking transformation in Informatica?
In the data masking transformation, Dependent Column will be ZIP code and Output column will be City or State columns. This concludes the detailed explantion of data masking transformation in Informatica.
How to perform SQL transformation in Informatica workflow?

What are the prerequisites for data masking in Informatica?
In order to demonstrate more on data masking, the primary pre-requisite is the license for data masking transformation in Informatica. Random masking generates random nondeterministic masked data. The Data Masking transformation returns different values when the same source value occurs in different rows.
How to convert Informatica SQL transformation to passive mode?
SQL Transformation in Passive Mode: By default, Informatica SQL transformation is in Active mode. By checking this option, you can convert it to Passive Mode. For this demo, we will write a Select Query.
