Credential Types

Indicio uses a variety of credential types, exchanges, and representations to provide the best solution to fit our customer's needs.

The technical specification or structure that defines how credential data is encoded, presented, and exchanged. Credential formats ensure that the data within a verifiable credential can be securely issued, shared, and verified across different systems. Key aspects of a credential format include how the data is digitally signed, the cryptographic techniques used, and how privacy-preserving features like selective disclosure or zero-knowledge proofs are implemented.

Indicio provides robust support for a variety of credential formats, enabling organizations to choose the format that best aligns with their use case and interoperability requirements including:

• JSON-LD (Linked Data): A format that integrates with semantic web technologies, allowing credentials to include rich metadata and context for better interoperability.

• SD-JWT (Selective Disclosure JWT): A JWT-based format with added support for selective disclosure, enabling granular control over what information is shared from a credential.

• mDL: Supports proximity based sharing of driver license.

• Open Badges 3.0: Supports educational achievements.

• DTC for digital passports (ICAO DTC Type 1 compliant): A digital travel credential derived from the data inside a user's passport to be easily held and shared before traveling.

• DTA for digital visas: Digital Travel Authorization that is easily digitized and shared before the traveler arrives and goes through customs or security.

• DIF Presentation Exchange: a codified presentation definition format for verifiers to use to articulate proof requirements.

• W3C Verifiable Credential standards compliant: A set of standards developed by the World Wide Web Consortium to enable the issuance, sharing, and verifiaction of digital credentials in a privacy respecting manner.

• AnonCreds: A privacy-preserving format that supports privacy-preserving features such as selective disclosure, predicate proofs, and zero-knowledge proofs, allowing users to share only the necessary information from a credential without revealing the entire dataset. JSON Web Tokens (JWT): A widely-used format based on JSON that is compact and easy to process, suitable for web-based applications and lightweight implementations.

• BBS+: A secure, multi-message digital signature protocol, supporting proving knowledge of a signature.

By offering this flexibility, Indicio empowers organizations to build decentralized identity solutions that are secure, private, and interoperable across diverse systems and industries.
