Proceedings of the 3rd International Workshop on Trends in Digital Identity (TDI 2025)

Digital identity is increasingly recognized as a fundamental building block in the development and deployment of digital infrastructures and services across a wide range of sectors, including e-commerce, e-government, healthcare, and finance. As the adoption of digital technologies accelerates, the need for secure and reliable identity management solutions grows significantly and becomes the cornerstone of other security services, such as access control. However, this increased demand presents numerous challenges, including technical issues like security, interoperability, and usability, as well as legal and regulatory concerns related to data protection, privacy, and compliance. To effectively address these challenges, collaboration among researchers and practitioners from various fields is essential. This workshop seeks to bring together representatives from academia, research institutions, industry, public administrations, and standardization bodies to discuss the evolving landscape of digital identity management. The objective is to drive a transformation process that ensures security guarantees, robust data protection, compliance, and a foundation of trust in digital services. By fostering these discussions, the workshop provides a unique opportunity for interdisciplinary collaboration, with the aim of shaping the future of digital identity.
