Data anonymization is a data protection process focused on privacy protection. The role of data anonymization is to encrypt or remove personally identifiable information from data sets. In this manner, people from whom the data was collection remain remain anonymous.

Data anonymization is often used in the medical field, as well as in data-sensitive statistics analysis. If you need to render the data you’re working on anonymous, you can use one of the tools listed below.

What are the best data anonymization tools?


ARX Data Anonymization Tool

ARX is an open source software for anonymizing sensitive personal data. The tool transforms datasets into syntactic privacy models that mitigate attacks leading to privacy breaches.

ARX removes direct identifiers such as names from datasets and adds further constraints on indirect identifiers, such as email addresses or phone numbers. The tools also provides built-in data import facilities for relational databases (MS SQL, DB2, SQLite, MySQL), MS Excel and CSV files.

You can download ARX Data Anonymization for free from the tool’s official website.



Data can also come in the form of images. If you need a tool to blur images, we recommand Anonymizer. The software detects faces, car number plates and other image information in various scales and orientations and applies blurring filters to make the information unreadable.

The Anonymizer SDK is a standalone C/C++ library for Windows and Linux. You can use it to anonymize street-view photos, webcam photos, or any other photos for which privacy is a major concern.

You can download Anonymizer from Eyedea and try it out for free.
