Amnesia: sovereignty score and 8 European alternatives

Amnesia is an anonymisation tool for datasets, developed by Athena Research Center and offered through the OpenAIRE initiative. It replaces secondary identifiers such as date of birth and postal code so that individuals can no longer be identified in the data. Amnesia supports k-anonymity and km-anonymity for tabular data and for data with multiple values per entry. It is available as a downloadable desktop application for Windows and Linux, and through a ReST API for integration into existing systems.

Athena Research Center is a Greek research and innovation centre headquartered in Marousi, near Athens. The source code is published on GitHub under a BSD 3-Clause licence, with some files carrying Apache licence terms. Because the software can run on the organisation's own infrastructure, a European organisation can anonymise data without sending raw data to an external service. The online demo, which the provider intends for practice only, does not state a hosting location or a GDPR commitment.

Why digital sovereignty matters with Amnesia

Amnesia is headquartered in GR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Amnesia scores best on data residency.

Amnesia is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Amnesia together with your other vendors and gives a total score, a heatmap and the main risk drivers.
