ARX Data Anonymization Tool vs DataVeil

ARX Data Anonymization Tool is open-source software for anonymizing sensitive personal data and examining privacy risk and data utility. Its graphical application supports data import and cleansing, transformation-rule setup, tailoring anonymized datasets, and analysis of utility and residual re-identification risk. It imports CSV, MS Excel, and relational database data, including MS SQL, DB2, MySQL, and PostgreSQL. Listed methods include k-anonymity, l-diversity, t-closeness, δ-presence, risk-based criteria, and semantic models such as differential privacy. ARX exports displayed tables to CSV and compares input with transformed data using information-loss models, descriptive statistics, and application-specific analyses. Its risk analysis reports prosecutor, journalist, and marketer attack risks, estimates population uniqueness, and can identify HIPAA Safe Harbor identifiers and further quasi-identifiers. A Java library and API can add anonymization capabilities to Java programs. The tool is free under Apache License 2.0 and supports Linux, macOS, Windows, API, and self-hosted options. The maker provides PGP/GPG-signed checksums for download integrity and states the software is provided without warranties or conditions.

DataVeil masks sensitive SQL database data with fictitious values for testing, development, training, analytics and support. It supports Microsoft SQL Server 2014 or later, Azure SQL DB and MI, MySQL 5.7 or later, Oracle 12c or later, and PostgreSQL 14 or later. Choose random masking or deterministic masking, which can keep values consistent across databases and separate runs. Masks can retain value formats and partial content to help preserve statistical distributions. Discovery algorithms check suspected identifiers and account numbers, and users can add regular-expression patterns. DataVeil maintains referential integrity for defined foreign keys and supports user-defined dependencies. Before writing masked values, users can compare originals and results side by side. Projects run from the GUI, command line or batch files. The Community license includes generated PDF reports and automatically multi-threaded masking. It runs as a Java client with an embedded JDK 21 and uses JDBC. The free Community License never expires and covers databases up to 10GB. The Team license is $5,690 a year for an example configuration; its price depends on connectivity options and source-data size.
