eidigitaalisia

Eidigitaalisia is a concept in digital sociology and information science that describes the modular, user-controlled construction and management of digital identities across multiple platforms. It foregrounds portability of identity data, granular consent, and context-specific identity fragments rather than a single, centralized profile.

The term is a Finnish neologism formed from e- (electronic) and digi- (digital) with a generic -taalisia noun suffix. It is used in discussions about self-sovereign identity and interoperable identity technologies, including decentralized identifiers and verifiable credentials.

In practice, eidigitaalisia refers to systems and designs that let individuals assemble identity attributes as needed, store them in digital wallets, and share them selectively with services under user consent. Real-world analogues include self-sovereign identity frameworks and portable identity wallets, which aim to reduce vendor lock-in and increase privacy.

Benefits include enhanced user agency and privacy, and potential benefits for cross-platform trust. Challenges include achieving interoperability among diverse platforms, ensuring security, protecting against data leakage, and navigating regulatory requirements. Some critics warn of fragmentation and usability hurdles.
