Every day, organisations across Europe generate vast amounts of valuable data. Most of it remains unused, not because it lacks value, but because it cannot be shared securely.

As AI increases the demand for high-quality, trustworthy datasets, solving this challenge has become a strategic priority for Europe.

This is precisely where Project TITAN (Trusted envIronments for confidenTiAl computiNg) comes in.

Funded by the European Union as part of its Research and Innovation programme, TITAN brings together 16 organisations from 10 countries to develop a secure software platform that enables sensitive data to be shared, analysed and exploited responsibly, without ever exposing confidential information.

Think of it as a secure reading room in a library. Researchers can consult books, analyse their contents and generate new knowledge, but the original documents never leave the room. TITAN applies the same principle to data: organisations can extract valuable insights while the underlying sensitive information remains protected at all times.

The impact reaches far beyond technology. Across Europe, vast amounts of health records, financial information and public-sector datasets remain underused because the mechanisms required to establish trust between organisations are still too complex. At the same time, GDPR-compliant, high-quality datasets have become one of the scarcest and most valuable resources for developing reliable AI systems.

By providing a trusted framework for secure collaboration, TITAN enables organisations to unlock the value of sensitive data that would otherwise remain inaccessible. This opens the door to faster scientific discoveries, more effective public services and new opportunities for AI-driven innovation, all while preserving citizens’ privacy.

The project also supports Europe’s broader ambition to strengthen its digital sovereignty. While achieving complete technological independence will take time, reinforcing trust, governance and data protection today represents a pragmatic and essential step towards building a resilient European data ecosystem.

Turning trust into technology

Making trusted data sharing a reality requires more than a vision—it requires practical technology.

As a core technology partner, Fujitsu plays a central role in transforming TITAN’s ambitions into practical, operational capabilities.

Leveraging its expertise in AI, cybersecurity, privacy engineering and distributed technologies, Fujitsu is developing solutions that allow organisations to collaborate with confidence while maintaining the highest standards of security, transparency and regulatory compliance.

One of Fujitsu’s key contributions is DataShade, an advanced data anonymisation solution designed to maximise the value of sensitive datasets while protecting individual identities.

Using privacy-enhancing technologies such as differential privacy and k-anonymity, DataShade removes personally identifiable information while preserving the quality and usefulness of the data for AI and research. It also assesses the risk of re-identification, enabling organisations to share datasets with confidence while ensuring that individuals remain protected.

Fujitsu is also developing the Agreement Manager (AGRM), a governance component that addresses one of the biggest barriers to secure data sharing: establishing trust between organisations.

AGRM automates the creation and management of data-sharing agreements by defining who can access which datasets, under what conditions and for how long. Every agreement is secured through digital signatures and distributed ledger technology (DLT), creating a transparent, trustworthy and fully auditable record of every decision while helping organisations demonstrate compliance with regulations such as GDPR.

Together, DataShade and AGRM demonstrate that privacy, governance and innovation are not opposing objectives, they reinforce one another. By embedding trust directly into the data-sharing process, they enable organisations to collaborate more effectively without sacrificing control over sensitive information.

Supporting Europe’s data strategy

Beyond the development of individual technical components, Fujitsu’s contributions directly support the ambitions of the European Open Science Cloud (EOSC) and the European Data Strategy, both of which aim to create secure, interoperable and trustworthy European data spaces that accelerate research, foster innovation and strengthen Europe’s competitiveness.

Ultimately, the future of AI will depend on more than increasingly powerful algorithms. It will depend on organisations’ ability to collaborate around trusted, high-quality data in ways that respect privacy, strengthen governance and inspire confidence.

Projects such as TITAN demonstrate that privacy is not an obstacle to innovation, it is one of its essential enablers. By helping build the trusted foundations that make secure data collaboration possible, Fujitsu is contributing to a more resilient, sovereign and responsible European digital future.
