- They fall outside the scope of the RGPD, are respectful of everyone and can be put to use by all. 

  • Protect individuals,

- Avatars respect the privacy of individuals. 
- They guarantee the respect of confidentiality.

  • Maintain utility.

Sharing without revealing to exploit ethically


The protection of individuals is at the heart of the Avatar method and of Octopize's solutions, notably thanks to metrics that ensure and prove security. In particular, the method ensures compliance with the 3 criteria described in the G29 opinion of 05/2014 namely, individualization, correlation and inference.


Avatars allow sharing since the summary data resulting from the method are no longer personal data. They fall outside the framework of the RGPD, are respectful of everyone and can be used by all. The sharing also induces the transparency of the method and allows the reproducibility of the results.


Respecting the privacy of individuals is an ethical imperative. Avatars (synthetic data from our solution) guarantee respect for confidentiality. Our vision: "When we analyze data, there is no longer any justification for taking a risk of re-identification. "


Octopize, a Deeptech start-up, has developed a unique data anonymization technology. This breakthrough innovation facilitates access to data for secondary uses (innovation, research, sharing).

Heading towards ethical data for the benefit of all, respectful of everyone.

Our project


We are experts in Data Privacy / Data Sharing issues and the use of your personal data

Avatar, the personal data anonymization software

Octopize has developed a software dedicated to the processing and exploitation of personal data without compromising either their confidentiality or their informative value (secondary analyses).

Anonymization services with the Avatar solution

Our team also offers data anonymization services with its Avatar method. You provide us with a dataset, we configure the avatarization and return the anonymized dataset.
Our solution


Discover the Octopize solutions applied to different examples of use cases (sharing outside the EU, revaluation, etc.)

Data transfer outside the EU

This use case illustrates the problem of transferring personal data to a partner outside the European Union.

Risk limitation in internal use

This use case deals with precautionary notions in the use and governance of personal data. How to limit the risks linked to an internal use of this data?

Storage of spatio-temporal data

The "New York Taxi" use case presents a context of anonymization of spatio-temporal data. The difficulty lies in the particular nature of this data, where the combination of spatial and temporal dimensions accentuates the risk of re-identification.

Our collaborations

They trust us

Nantes University Hospital

We deploy our avatarization algorithm on large-scale medical data. Nantes University Hospital is interested in our solution to ensure privacy of patient data and quality retention for medical research.

SOS Médecins

We rework the complete data pipeline of SOS Médecins, from the collection of medical data to the production of a monitoring and predicting tool for physicians. This project involves extensive data management to handle more than 3 million medical records per year throughout France.

We integrated this scientific exploration project with the aim of advancing knowledge to fight cancer by organizing Data Challenges. Thanks to avatars, we allowed Data Challengers to work with anonymized databases available in Open Data.

Industrie pharmaceutique - client OCTOPIZE

Pharma industry

We work with the pharmaceutical industry and intervene on the anonymization of clinical trial data. Our expertise allows them to facilitate the sharing of data outside the EU and unlock secondary uses of the data collected without legal constraints or retention limits.
