8th IEEE International Workshop on Secure Digital Identity Management (SDIM 2025)

The goal of the workshop

Secure digital identity management, required by cloud services, federated services, or newest distributed and decentralized technologies such as blockchain and distributed ledger technologies, is receiving increasing attention from both service providers’ and end users’ perspectives, in terms of protection of enterprise assets and customers’ privacy in the cloud, and possibly in the future virtual reality environments as well, respectively.  This workshop solicits contributions describing state-of-the-art methodology and technology innovations in the field of secure identity management, encourages experience sharing (both positive and negative ones), and also welcomes work-in-progress ideas towards future concepts.

Workshop theme

The workshop is dedicated to the security and privacy aspects of identity management (IDM) in smart devices, the cloud, or blockchain and distributed ledger environment. Topics are articulated around several important themes as “concept design”, “enabling technologies”, “federated identities”, “decentralized identities” and “applications”. It is expected they will attract both theoretical and empirical works from the IDM society, the cloud computing society, and the decentralized identity management society.

Scope of the workshop

Any submission whose content is relevant to the area of secure identity management will be considered, but  any submission whose subject matter is related to one of the following topics will be particularly welcome.  Practice-oriented approaches will also be appreciated. 

  • Identity-based access control and personal data management 
  • Biometric identities 
  • Privacy-preserving identity attribute processing and analysis  
  • Service-oriented architecture for IDM in cloud 
  • Identity federations & trust fabrics 
  • Cryptographic methods for IDM 
  • PKI architecture, security policy, and operation method 
  • Identity management in the IoT environment  
  • Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) 
  • IDM on a blockchain, self-sovereign identity or other decentralized identity platform
  •  IDM in the virtual environment and its connection to the physical world 
  • Anonymization, pseudonymization, and other privacy / data protection methods
  • Legal, ethical, and socioeconomic aspects
