Data Masking

Data masking is a crucial data protection strategy. It plays a key role in today’s digital world. In this age of digital growth and increasing cyber threats, protecting sensitive information is more important than ever.

What is data masking?

Almost every organization does everything it can to protect personal data against hackers and other criminals. The ‘front door’ is firmly locked. But there is also a back door and sometimes it is wide open. Databases with personal data are copied for analysis or to test software. That’s where data leaks lurk.

Data masking is a method to anonymize or pseudonymize production data, so that the data can no longer be traced back to unique natural persons. At the same time, the representativeness of the data is maintained.

Pseudonymization

If it is desirable to make data traceable again, pseudonymization is a better option. This is also possible with data masking. In that case, all names are replaced by a fixed name according to a certain rule. This can be useful, for example, in medical analyses, where a doctor sometimes needs to be warned about an individual case.

Anonymize

With data masking you can both pseudonymize and anonymize. Anonymization is done by mixing personal data according to rules that the user enters himself. For example, by changing all names. For example, rules keep families together or maintain zip codes for geographical analysis. Anonymization is irreversible.

Why is data masking important?

In today’s digital world, data about all of us is collected and stored. Companies, governments and organizations have access to enormous amounts of data, including personal information such as names, addresses, telephone numbers and email addresses.

This data can be used for various purposes, such as providing personalized services and improving products. But if this data falls into the wrong hands, it can also be misused for criminal activities such as identity theft and fraud.

Data masking is therefore an important way to protect the privacy of individuals and reduce the risk of unauthorized access to sensitive information.
