Standards and Frameworks

OSIA (Open Standards Identity API) enables seamless connectivity between all components of the identity management ecosystem – independent of technology, solution architecture or vendor.

OSIA is an official International Telecoms Union (ITU) standard. ITU Standardization Sector (ITU-T) Recommendation X.1281 – APIs for interoperability of identity management systems.

The Accountable Digital Identity Architecture is a standardized, interoperable framework for decentralized identity services to ensure the authenticity of, and to establish trust in, digital identities. It’s built around core principles of user privacy (end-users hold and control their own data), no centralization of identity data, disclosure only with individual consent, and inclusivity for people regardless of technology access — with real-world applications spanning healthcare, government, education, financial services, and enterprise identity. As of April 2025, ADIA and its members have joined SIA in a strategic partnership that granted SIA an exclusive license to the ADIA Digital ID Trust Framework Specification.

The eDocument Scheme for Evaluating Physical Security (eSEC) has been designed by the SIA’s Document Security Working Group and other experts of the ID documents sector to help governments develop secure eDocuments. It can be used as a self-assessment tool to evaluate the physical security of current documents, the security impact of additional design changes, or simply to learn and understand what is required to build a ‘secure eDocument’.

SIDI Hub is a community where governments, NGOs, standards bodies, private entities, multilaterals and academic organizations collaborate following a shared roadmap.
