~ Introduction ~
The Privacy & Personal Data Management Session of the Solid Symposium 2026 aims to bring together
technical and legal-ethical experts to discuss Solid as a concrete system for data governance,
to ground the debate on emergent problems from both a technical perspective and a
legal-ethical perspective of data protection.
In this edition, we aim to continue the discussions around technical and legal privacy aspects that
should be incorporated into Solid. We aim to draw from a broad interdisciplinary perspective on privacy
and personal data management, including human-centric perspectives on privacy and the emergence of
personal data spaces and digital wallets. Towards this aim, the programme will be a mix of flash talks
from extended abstracts and presentations of short papers to showcase the
current state of research and trajectories in privacy-related research in Solid.
~ Call for Contributions ~
The Privacy & Personal Data Management Session aims to bring together technical and legal-ethical experts to discuss
Solid as a concrete system for data governance, to ground the debate on emergent problems from both a technical
perspective and a legal-ethical perspective of data protection. The first three editions of this Session were co-located
with the Solid Symposium 2023, 2024 and 2025, and were hosted in Nürnberg, Germany,
Leuven, Belgium,
and Leiden, Netherlands,
respectively.
The previous editions explored privacy-related problems concerning identity management, security, and authorisation
in Solid from an interdisciplinary perspective.
In this edition, we aim to discuss technical and legal privacy aspects that should be incorporated into Solid.
We aim to draw from a broad interdisciplinary perspective on privacy and personal data management, including
human-centric perspectives and the emergence of personal data spaces and digital wallets.
The session welcomes a broad range of methodologies not limited to semantics and knowledge engineering,
proof-of-concept implementations, and methodologies drawn from legal and social sciences.
Thus, this session comprises presentations from short papers and flash talks from extended abstracts in related areas
not limited to the following:
- User-centric perspectives on privacy, security, and transparency
- Regulatory/legal compliance (e.g., GDPR, DGA, CCPA) in decentralised settings
- Legal agreements for automated data exchange based on legal grounds beyond consent
- Semi-automation of consent support systems
- Interfaces for consenting / consent withdrawing / rights exercising / usage control
- Access and usage control policies
- Policy management and enforcement
- Negotiation of access to data through agents
- Privacy-preserving agents and autonomous multi-agent systems
- Usability of data-related decisions on Solid
- Solid for personal data spaces
- Personal knowledge graphs
- FAIR management and interoperability of personal data spaces
- Digital identities, data wallets (e.g., impact of EUDI regulation)
- Solutions for data sovereignty, identity management and authentication
- Auditing Pods for transparency & accountability (logging, registries, …)
- Compliance with standards (e.g., Web or security standards)
- Privacy-preserving data analysis technologies / privacy enhancing technologies
- Risk and impact assessments
