The “Re-identification Challenge”: Now OPEN for registrations

The CHAIMELEON project has just launched the “Re-identification Challenge”! AI4HI and EUCAIM innovators are encouraged to help tackle one of the most pressing issues in today’s digital landscape – ensuring the protection of personal data. We are seeking innovators like you to test the effectiveness of de-identification processes in European AI projects.

Participants, exclusively comprising AI4HI and EUCAIM researchers, will be tasked with re-identifying medical images that have been previously pseudonymized using one of the de-identification methods employed in ongoing AI4HI projects, namely CHAIMELEON or ProCancer-I.

Participants will be challenged to re-identify pseudonymized medical studies with two de-identification methods used in ongoing AI4HI projects.

Are you interested in testing the effectiveness of de-identification processes in European AI projects to safeguard patient data in AI and health imaging?

Don’t miss out on the opportunity to demonstrate your expertise, collaborate with fellow researchers, and make meaningful strides in safeguarding patient privacy.

A total prize pool of €10,000 awaits the winners to be distributed among the top performers based on the number of re-identified patients.
