New SYNAPSIS platform enables secure sharing of video and audio data

The Netherlands -- Researchers will soon have new opportunities to safely share and reuse video and audio materials. Through the SYNAPSIS project, universities and partners are developing a platform that allows recordings to be easily anonymised without losing valuable research information. The initiative aims to support responsible open science while improving privacy protection.

An increasing number of researchers in fields such as linguistics, communication science and other disciplines work with audiovisual data, including interviews, classroom observations and recordings of real-life interactions. At the same time, many recordings remain unused because privacy regulations make sharing complex. SYNAPSIS provides practical tools to lower this barrier and make data more accessible for future research.

"Video and audio data are essential for understanding human communication," says principal investigator Mark Dingemanse (Radboud University). "With SYNAPSIS, we make it possible to share data securely while safeguarding participants' privacy. In this way, we strengthen open science in a responsible manner."

Automatic anonymisation

Through a secure online environment, researchers can upload recordings and anonymise them in just a few steps. The platform uses technology to mask faces and voices and remove identifiable features while preserving important information such as movements, gestures and interactions. No programming knowledge is required, and the system can be used both in the cloud and locally.

According to data steward Henk van den Heuvel (Radboud University), this will help researchers handle sensitive data more effectively.

"By better protecting personal information, it becomes easier to manage audiovisual data according to FAIR principles and to share it responsibly."

Training and digital skills

In addition to technology, SYNAPSIS also focuses on training and support. In collaboration with partner universities, Vrije Universiteit Amsterdam will organise several training events where researchers, data stewards and support staff learn how to work with audiovisual data in a privacy-conscious way -- from data collection to archiving. Bogdana Huma (VU Amsterdam) and Inge Slouwerhof (Radboud University) are involved in organising the Masking Lab, a one-day workshop for research support professionals. Wim Pouw (Tilburg University) and James Trujillo (University of Amsterdam, ILLC) are involved in organising the Masking Schools, workshops on privacy-preserving techniques for audiovisual data.

"Our goal is to make innovative machine learning accessible to researchers without a technical background," says researcher Babajide Owoyele (Radboud University). "In this way, we strengthen digital skills across a wide range of disciplines."

Collaboration between universities

SYNAPSIS is a collaboration between Radboud University, Vrije Universiteit Amsterdam, Tilburg University, University of Amsterdam and Erasmus University Rotterdam, with support from SURF, DANS and international partners. The project is funded by the Dutch Research Council (NWO) through a programme for Thematic Digital Competence Centres (TDCC).

"We should archive and share our audiovisual data in a secure way such that people's identities are protected. We can increase the security and protection levels through masking, while maintaining the original purposes of transparency, verifiability, and open science," says Wim Pouw, Associate Professor at Tilburg University (Department of Computational Cognitive Science) and Radboud University (Donders Institute).

Over the next two years, the platform will be tested at multiple universities, and more than one hundred researchers and data stewards will receive training in privacy-conscious data management.
