Data Masking

Protect your personal data

Anonymization of personal data

I. Data masking and anonymization


Data masking is a technology which aims to prevent the manipulation of personal data by giving users fictitious data (but realistic) instead of real personal data.

The anonymization of personal data consists in modifying the content or structure of this data in order to make it impossible to “re-identify” users (physical or legal) or entities concerned.

Personal data exposed to staff

With the constitution of test data sets intended to populate different environments (such as test, Quality Assurance (QA), qualification, training, dedicated to young recruits, etc…), there is a growing risk of personal and confidential data originating from production becoming visible to unauthorized staff such as testers, QA staff and developers. These users are not authorized to visualize this personal production data  (name of persons, addresses, mobile numbers, bank account numbers, social security details) and can introduce a potential data leak. Since the security level of development servers are not as high as production servers, a desensitization of personal and confidential data is needed.

70% of security incidents come from internal sources


To be effective, anonymization must preserve the usability of data:

  • Maintain its readability (preservation of the data format)
  • Maintain data format and type (an adress must remain an adress for example)
  • Retains values from one transformation to another
  • Ensures cross-platform consistency (the same anonymization rule used in different databases)

Take a look at our infographic and find out how Data Masking can anonymize production data while maintaining its usability. To go even further, check out our article about the 5 most common questions about data anonymization.

Analyze the concepts, mechanisms and solutions that data masking and anonymization can provide, as well as the latest implementation scenarios and algorithms in our Data Masking White Paper

II. GDPR and data protection

GDPR (General Data Protection Regulation) is in application since 25 May 2018. This regulation relates to the protection of physical persons against the misuse of personal data during processing and the free movement of such data.

Become an expert on our GDPR page (Definition, when does it apply?, Who is impacted? How do the fines work?, How can I protect my company from data leak?..).

Find out the issues related to this new european regulation in our White Paper. Prepare for these challenges by watching our webinar.

Any data protection project (GDPR, CCPA, etc.) begins by identifying personal data to feed your registry. Discover how to detect them in this article
